Blueprint Reference

Blueprints are text files in the TOML format that describe customizations for the image you are building. To be used in the 🔵 on premises environment.

Analogously the request content of the image-builder /compose request describes customizations of an image the 🟤 hosted service should be building. Not all customizations are supported in the API but those existing, are highlighted here with a 🟤 hosted label.

An important thing to note is that these customizations are not applicable to all image types. osbuild-composer currently has no good validation or warning system in place to tell you if a customization in your blueprint is not supported for the image type you're building. The customization may be silently dropped.

A very basic blueprint with just the required attributes at the root looks like:

name = "basic-example"
description = "A basic blueprint"
version = "0.0.1"

Where:

  • The name attribute is a string that contains the name of the blueprint. It can contain spaces, but they will be converted to - when it is imported into osbuild-composer. It should be short and descriptive.
  • The description attribute is a string that can be a longer description of the blueprint and is only used for display purposes.
  • The version attribute is a string that contains a semantic versioning compatible version number. If a new blueprint is uploaded with the same version the server will automatically bump the PATCH level of the version. If the version doesn't match it will be used as is. For example, uploading a blueprint with version set to 0.1.0 when the existing blueprint version is 0.0.1 will result in the new blueprint being stored as version 0.1.0.

You can upload a blueprint with the osbuild-composer blueprints push $filename command, the blueprint will then be usable in osbuild-composer compose as the name you gave it.

Blueprints have two main sections, the content and customizations sections.

Distribution selection with blueprints 🔵 🟤​

The blueprint now supports a new distro field that will be used to select the distribution to use when composing images, or depsolving the blueprint. If distro is left blank it will use the host distribution. If you upgrade the host operating system the blueprints with no distro set will build using the new os. You can't build an OS image that differs from the host OS that Image Builder lives on.

eg. A blueprint that will always build a Fedora 38 image, no matter what version is running on the host:

Note that osbuild-composer prior to version 100 didn't use a dot . to separate major and minor release versions in the distro name. New versions are backward compatible, so they will still accept the old distro names of distributions supported up to the version 100. However, going forward, it is strongly advised to use the new naming scheme. Future distribution versions won't be backward compatible (e.g. rhel-100 won't work in the future for RHEL 10.0, but one will have to use rhel-10.0).

name = "tmux"
description = "tmux image with openssh"
version = "1.2.16"
distro = "fedora-38"

[[packages]]
name = "tmux"
version = "*"

[[packages]]
name = "openssh-server"
version = "*"
name = "tmux"
description = "tmux image with openssh"
version = "1.2.16"
# for osbuild-composer version < 100
# distro = "rhel-84"
distro = "rhel-8.4"

[[packages]]
name = "tmux"
version = "*"

[[packages]]
name = "openssh-server"
version = "*"

Content​

The content section determines what goes into the image from other sources such as packages, package groups, or containers. Content is defined at the root of the blueprint.

Packages 🔵 🟤​

The packages and modules lists contain objects with a name and optional version attribute.

  • The name attribute is a required string and can be an exact match, or a filesystem-like glob using * for wildcards and ? for character matching.
  • The version attribute is an optional string can be an exact match or a filesystem-like glob of the version using * for wildcards and ? for character matching. If not provided the latest version in the repositories is used.

Currently there are no differences between packages and modules in osbuild-composer. Both are treated like an rpm package dependency.

When using virtual provides as the package name the version glob should be *. And be aware that you will be unable to freeze the blueprint. This is because the provides will expand into multiple packages with their own names and versions.

For example, to install tmux-2.9a and openssh-server-8.* packages, add this to your blueprint:

[[packages]]
name = "tmux"
version = "2.9a"

[[packages]]
name = "openssh-server"
version = "8.*"

Or in alternative syntax1:

packages = [
    { name = "tmux", version = "2.9a" },
    { name = "openssh-server", version = "8.*" }
]

Groups 🔵​

The groups list contains objects with a name-attribute.

  • The name attribute is a required string and must match the id of a package group in the repositories exactly.

groups describes groups of packages to be installed into the image. Package groups are defined in the repository metadata. Each group has a descriptive name used primarily for display in user interfaces and an ID more commonly used in kickstart files. Here, the ID is the expected way of listing a group. Groups have three different ways of categorizing their packages: mandatory, default, and optional. For the purposes of blueprints, only mandatory and default packages will be installed. There is no mechanism for selecting optional packages.

For example, if you want to install the anaconda-tools group, add the following to your blueprint:

[[groups]]
name = "anaconda-tools"

Or in alternative syntax1:

groups = [
    { name = "anaconda-tools" }
]

Containers 🔵 🟤​

The containers list contains objects with a source and optional tls-verify attribute.

These list entries describe the container images to be embedded into the image.

  • The source attribute is a required string and is a reference to a container image at a registry.
  • The name attribute is an optional string to set the name under which the container image will be saved in the image. If not specified name falls back to the same value as source.
  • The tls-verify attribute is an optional boolean to disable TLS verification of the source download. By default this is set to true.
  • The local-storage attribute is an optional boolean to pull the container image from the host's local-storage. By default this is set to false.

The container is pulled during the image build and stored in the image at the default local container storage location that is appropriate for the image type, so that all supported container tools like podman and cri-o will be able to work with it.

The embedded containers are not started, to do so you can create systemd unit files or quadlets with the files customization.

Container images from local-storage are only supported on-premise.

To embed the latest fedora container from http://quay.io and a container from your host, add this to your blueprint:

[[containers]]
source = "quay.io/fedora/fedora:latest"

[[containers]]
source = "localhost/test:latest"
local-storage = true

Or in alternative syntax1:

containers = [
    { source = "quay.io/fedora/fedora:latest" },
    { source = "quay.io/fedora/fedora-minimal:latest", tls-verify = false, name = "fedora-m" },
    { source = "localhost/test:latest", local-storage = true },
]

To access protected container resources a containers-auth.json(5) file can be used, see Container registry credentials.

Customizations​

In the customizations we determine what goes into the image that's not in the default packages defined under Content.

Hostname 🔵 🟤​

customizations.hostname is an optional string that can be used to configure the hostname of the final image:

[customizations]
hostname = "baseimage"

This is optional and can be left out to use the default hostname.

Kernel 🔵 🟤​

Kernel Command-Line Arguments​

An optional string that allows to append arguments to the bootloader kernel command line:

[customizations.kernel]
append = "nosmt=force"

SSH Keys 🔵 🟤​

An optional list of objects containing:

  • The user attribute is a required string and must match the name of a user in the image exactly.
  • The key attribute is a required string that contains the public key to be set for that user.

Warning: key expects the entire content of the public key file, traditionally ~/.ssh/id_rsa.pub but any algorithm supported by the operating system in the image is valid

Note: If you are adding a user you can add their SSH key in the additional users customization instead.

Set an existing user's SSH key in the final image:

[[customizations.sshkey]]
user = "root"
key = "PUBLIC SSH KEY"

The key will be added to the user's authorized_keys file in their home directory.

Additional Users 🔵​

An optional list of objects that contain the following attributes:

  • name a required string that sets the username.
  • description an optional string.
  • password an optional string.
  • key an optional string.
  • home an optional string.
  • shell an optional string.
  • groups an optional list of strings.
  • uid an optional integer.
  • gid an optional integer.

Warning: key expects the entire content of the public key file, traditionally ~/.ssh/id_rsa.pub but any algorithm supported by the operating system in the image is valid

Note: If the password starts with $6$, $5$, or $2b$ it will be stored as an encrypted password. Otherwise it will be treated as a plain text password.

Add a user to the image, and/or set their ssh key. All fields for this section are optional except for the name. The following is a complete example:

[[customizations.user]]
name = "admin"
description = "Administrator account"
password = "$6$CHO2$3rN8eviE2t50lmVyBYihTgVRHcaecmeCk31L..."
key = "PUBLIC SSH KEY"
home = "/srv/widget/"
shell = "/usr/bin/bash"
groups = ["widget", "users", "wheel"]
uid = 1200
gid = 1200

Additional groups 🔵 🟤​

An optional list of objects that contain the following attributes:

  • name a required string that sets the name of the group.
  • gid a required integer that sets the id of the group.
[[customizations.group]]
name = "widget"
gid = 1130

Timezone 🔵 🟤​

An optional object that contains the following attributes:

  • timezone an optional string. If not provided the UTC timezone is used..
  • ntpservers an optional list of strings containing NTP servers to use. If not provided the distribution defaults are used.
[customizations.timezone]
timezone = "US/Eastern"
ntpservers = ["0.north-america.pool.ntp.org", "1.north-america.pool.ntp.org"]

The values supported by timezone can be listed by running the command:

$ timedatectl list-timezones

Some image types have already NTP servers setup such as Google Cloud images. These cannot be overridden because they are required to boot in the selected environment. However, the timezone will be updated to the one selected in the blueprint.

Locale 🔵 🟤​

An optional object that contains the following attributes to customize the locale settings for the system:

  • languages an optional list of strings containing locales to be installed.
  • keyboard an optional string to set the keyboard layout.

Multiple languages can be added. The first one becomes the primary, and the others are added as secondary. You must include one or more languages or keyboards in the section.

[customizations.locale]
languages = ["en_US.UTF-8"]
keyboard = "us"

The values supported by languages can be listed by running can be listed by running the command:

$ localectl list-locales

The values supported by keyboard can be listed by running the command:

$ localectl list-keymaps

Firewall 🔵 🟤​

An optional object containing the following attributes:

  • ports an optional list of strings containing ports (or port ranges) and protocols to open.
  • services an optional object with the following attributes containing services to enable or disable for firewalld.
    • enabled optional list of strings for services to enable.
    • disabled optional list of strings for services to disable.

By default the firewall blocks all access, except for services that enable their ports explicitly such as the sshd. The following blueprint can be used to open other ports or services.

Note: Ports are configured using the port:protocol format; port ranges are configured using portA-portB:protocol format:

[customizations.firewall]
ports = ["22:tcp", "80:tcp", "imap:tcp", "53:tcp", "53:udp", "30000-32767:tcp", "30000-32767:udp"]

Numeric ports, or their names from /etc/services can be used in the ports enabled/disabled lists.

The blueprint settings extend any existing settings in the image templates. Thus, if sshd is already enabled, it will extend the list of ports with those already listed by the blueprint.

If the distribution uses firewalld you can specify services listed by firewall-cmd --get-services in a customizations.firewall.services section:

[customizations.firewall.services]
enabled = ["ftp", "ntp", "dhcp"]
disabled = ["telnet"]

Remember that the firewall.services are different from the names in /etc/services.

Both are optional, if they are not used leave them out or set them to an empty list []. If you only want the default firewall setup this section can be omitted from the blueprint.

Note: The Google and OpenStack templates explicitly disable the firewall for their environment. This cannot be overridden by the blueprint.

Systemd Services 🔵 🟤​

An optional object containing the following attributes:

  • enabled an optional list of strings containing services to be enabled.
  • disabled an optional list of strings containing services to be disabled.
  • masked optional list of strings for services to mask.

If a service enabled or disabled through the corresponding attributes does not exist in the image that is being built then this customization will fail and the build will fail as a result. However, the corresponding package is not required on the image when masking a service.

[customizations.services]
enabled = ["sshd", "cockpit.socket", "httpd"]
disabled = ["postfix", "telnetd"]
masked = ["rpcbind"]

This section can be used to control which services are enabled at boot time. Some image types already have services enabled or disabled in order for the image to work correctly, and cannot be overridden. For example, ami image type requires sshd, chronyd, and cloud-init services. Without them, the image will not boot. Blueprint services do not replace these services, but add them to the list of services already present in the templates, if any.

The service names are systemd service units. You may specify any systemd unit file accepted by systemctl enable, for example, cockpit.socket:

Files and directories 🔵 🟤​

You can use blueprint customizations to create custom files and directories in the image. When using the custom files and directories customization, the following rules apply:

  • The path must be an absolute path and must be under /etc, /root, /usr/local/bin or /usr/local/sbin.
  • There must be no duplicate paths of the same directory.
  • There must be no duplicate paths of the same file.

These customizations are not supported for image types that deploy ostree commits (such as edge-raw-image, edge-installer, edge-simplified-installer). The only exception is the Fedora iot-raw-image image type, which supports these customizations.

Directories​

You can create custom directories by specifying items in the customizations.directories list. The existence of a specified directory is handled gracefully only if no explicit mode, user or group is specified. If any of these customizations are specified and the directory already exists in the image, the image build will fail. The intention is to prevent changing the ownership or permissions of existing directories.

The following example creates a directory /etc/foobar with all the default settings:

[[customizations.directories]]
path = "/etc/foobar"
mode = "0755"
user = "root"
group = "root"
ensure_parents = false
  • path is the path to the directory to create. It must be an absolute path under /etc. This is the only required field.
  • mode is the octal mode to set on the directory. If not specified, the default is 0755. The leading zero is optional.
  • user is the user to set as the owner of the directory. If not specified, the default is root. Can be specified as user name (string) or as user id (integer).
  • group is the group to set as the owner of the directory. If not specified, the default is root. Can be specified as group name (string) or as group id (integer).
  • ensure_parents is a boolean that specifies whether to create parent directories as needed. If not specified, the default is false.

Files​

You can create custom files by specifying items in the customizations.files list. You can use the customization to create new files or to replace existing ones, if not restricted by the policy specified below. If the target path is an existing symlink to another file, the symlink will be replaced by the custom file.

Please note that the parent directory of a specified file must exist. If it does not exist, the image build will fail. One can ensure that the parent directory exists by specifying it in the customizations.directories list.

In addition, the following files are not allowed to be created or replaced by policy:

  • /etc/fstab
  • /etc/shadow
  • /etc/passwd
  • /etc/group

Using the files customization comes with a high chance of creating an image that doesn't boot. Use this feature only if you know what you are doing. Although the files customization can be used to configure parts of the OS which can also be configured by other blueprint customizations, this use is discouraged. If possible, users should always default to using the specialized blueprint customizations. Note that if you combine the files customizations with other customizations, the other customizations may not work as expected or may be overridden by the files customizations.

The following example creates a file /etc/foobar with the contents Hello world!:

[[customizations.files]]
path = "/etc/foobar"
mode = "0644"
user = "root"
group = "root"
data = "Hello world!"
  • path is the path to the file to create. It must be an absolute under /etc. This is the only required field.
  • mode is the octal mode to set on the file. If not specified, the default is 0644. The leading zero is optional.
  • user is the user to set as the owner of the file. If not specified, the default is root. Can be specified as user name (string) or as user id (integer).
  • group is the group to set as the owner of the file. If not specified, the default is root. Can be specified as group name (string) or as group id (integer).
  • data is the plain text contents of the file. If not specified, the default is an empty file.

Note that the data property can be specified in any of the ways supported by TOML. Some of them require escaping certain characters and others don't. Please refer to the TOML specification for more details.

Installation device 🔵 🟤​

The customizations.installation_device variable is required by the edge-simplified-installer image. It allows the user to define the destination device for the installation.

[customizations]
installation_device = "/dev/sda"

Ignition 🔵 🟤​

The customizations.ignition section allows users to provide Ignition configuration files to be used in edge-raw-image and edge-simplified-installer images. Check the RHEL for Edge (r4e) butane specification for a description of the supported configuration options.

The blueprint configuration can be done either by embedding an Ignition configuration file into the image (only available for edge-simplified-installer), or providing a provisioning URL that will be fetched at first boot.

ignition.embedded configuration​

[customizations.ignition.embedded]
config = "eyJpZ25pdGlvbiI6eyJ2ZXJzaW9uIjoiMy4zLjAifSwicGFzc3dkIjp7InVzZXJzIjpbeyJncm91cHMiOlsid2hlZWwiXSwibmFtZSI6ImNvcmUiLCJwYXNzd29yZEhhc2giOiIkNiRqZnVObk85dDFCdjdOLjdrJEhxUnhxMmJsdFIzek15QUhqc1N6YmU3dUJIWEVyTzFZdnFwaTZsamNJMDZkUUJrZldYWFpDdUUubUpja2xQVHdhQTlyL3hwSmlFZFdEcXR4bGU3aDgxIn1dfX0="

Add a base64 encoded Ignition configuration in the config field. This Ignition configuration will be included in the edge-simplified-installer image.

ignition.firstboot configuration​

[customizations.ignition.firstboot]
url = "http://some-server/configuration.ig"

Add a URL pointing to the Ignition configuration that will be fetched during the first boot in the url field. Available for both edge-simplified-installer and edge-raw-image.

FDO 🔵 🟤​

The customizations.fdo section allows users to configure FIDO Device Onboard (FDO) device initialization parameters. It is only available with the edge-simplified-installer or iot-simplified-installer image types.

The manufacturing_server_url is a required field.

The user must choose one of the device initialization methods providing diun_pub_key_insecure, diun_pub_key_hash or diun_pub_key_root_certs.

The user may provide an IFACE name at di_mfg_string_type_mac_iface.

[customizations.fdo]
manufacturing_server_url = "http://192.168.122.199:8080"
diun_pub_key_insecure = "true"
di_mfg_string_type_mac_iface = "enp2s0"

Repositories 🔵 🟤​

Third-party repositories are supported by the blueprint customizations. A repository can be defined and enabled in the blueprints which will then be saved to the /etc/yum.repos.d directory in an image. An optional filename argument can be set, otherwise the repository will be saved using the the repository ID, i.e. /etc/yum.repos.d/<repo-id>.repo.

Please note custom repositories cannot be used at build time to install third-party packages. These customizations are used to save and enable third-party repositories on the image. For more information, or if you wish to install a package from a third-party repository, please continue reading here.

The following example can be used to create a third-party repository:

[[customizations.repositories]]
id = "example"
name="Example repo"
baseurls=[ "https://example.com/yum/download" ]
gpgcheck=true
gpgkeys = [ "https://example.com/public-key.asc" ]
enabled=true

Since no filename is specified, the repo will be saved to /etc/yum.repos.d/example.repo.

The blueprint accepts the following options:

  • id (required)
  • name
  • filename
  • baseurls (array)
  • mirrorlist
  • metalink
  • gpgkeys keys (array)
  • gpgcheck
  • repo_gpgcheck
  • priority
  • ssl_verify

Note: the baseurls and gpgkeys fields both accept arrays as input. One of baseurls, metalink & mirrorlist must be provided

Repository GPG Keys​

The blueprint accepts both inline GPG keys and GPG key urls. If an inline GPG key is provided it will be saved to the /etc/pki/rpm-gpg directory and will be referenced accordingly in the repository configuration. GPG keys are not imported to the RPM database and will only be imported when first installing a package from the third-party repository.

Partitioning mode 🔵 🟤​

The customizations.partitioning_mode variable can be used to select how the disk image will be partitioned. auto-lvm will use raw unless there are one or more filesystem customizations in which case it will use LVM. lvm always uses LVM, even when there are no extra mountpoints. raw uses raw partitions even when there are one or more mountpoints.

Supported modes:

  • auto-lvm uses raw unless filesystem customizations are included.
  • raw always uses raw partitions
  • lvm always uses LVM partitions
[customizations]
partitioning_mode = "lvm"

Filesystems 🔵 🟤​

The blueprints can be extended to provide filesytem support. Currently the mountpoint and minimum partition minsize can be set. On RHEL-8, custom mountpoints are supported only since version 8.5. For older RHEL versions, only the root mountpoint, /, is supported, the size argument being an alias for the image size.

[[customizations.filesystem]]
mountpoint = "/var"
minsize = 2147483648

Filesystem customizations are currently not supported for the following image types:

  • image-installer
  • edge-installer (RHEL and CentOS) and iot-installer (Fedora)
  • edge-simplified-installer (RHEL and CentOS)

In addition, the following image types do not create partitioned OS images and therefore filesystem customizations for these types are meaningless:

  • edge-commit (RHEL and CentOS) and iot-commit (Fedora)
  • edge-container (RHEL and CentOS) and iot-container (Fedora)
  • tar
  • container

Allowed mountpoints (osbuild-composer version < 94)​

In addition to the root mountpoint, /, the following mountpoints and their sub-directories are allowed:

  • /var
  • /home
  • /opt
  • /srv
  • /usr
  • /app
  • /data
  • /tmp

Allowed mountpoints (osbuild-composer version >= 94)​

Arbitrary custom mountpoints are allowed, except for specific paths that are reserved for the OS.

The following mountpoints are not allowed (including their sub-directories):

  • /bin
  • /boot/efi
  • /dev
  • /etc
  • /lib
  • /lib64
  • /lost+found
  • /proc
  • /run
  • /sbin
  • /sys
  • /sysroot
  • /var/lock
  • /var/run

The following mountpoints are allowed, but their sub-directories are not allowed:

  • /usr

OpenSCAP 🔵 🟤​

From RHEL 8.7 & RHEL 9.1 support has been added for OpenSCAP build-time remediation. The blueprints accept two fields:

  • the datastream path to the remediation instructions (optional)
  • the profile_id of the desired security profile

If the datastream parameter is not provided, osbuild-composer will now provide a sensible default based on the selected distro.

Please see the OpenSCAP page for the list of available security profiles.

[customizations.openscap]
datastream = "/usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml"
profile_id = "xccdf_org.ssgproject.content_profile_cis"

OpenSCAP Tailoring​

It may be desirable to add or exclude OpenSCAP rules from the remediation scan, this can be achieved by specifying tailoring options for the OpenSCAP customizations. A tailoring file with a new tailoring profile ID is created and saved to the image. The new tailoring profile ID is created by appending the _osbuild_tailoring suffix to the base profile. For example, given tailoring options for the cis profile, tailoring profile xccdf_org.ssgproject.content_profile_cis_osbuild_tailoring will be created. The default namespace of the rules is org.ssgproject.content, so the prefix may be omitted for rules under this namespace, i.e. org.ssgproject.content_grub2_password and grub2_password are functionally equivalent.

Note: the generated tailoring file is saved to the image as /usr/share/xml/osbuild-oscap-tailoring/tailoring.xml

[customizations.openscap]
datastream = "/usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml"
profile_id = "xccdf_org.ssgproject.content_profile_cis"

[customizations.openscap.tailoring]
selected = [ "xccdf_org.ssgproject.content_bind_crypto_policy" ]
unselected = [ "grub2_password" ]

FIPS 🔵 🟤​

Enables/disables the system FIPS mode (disabled by default). Currently only edge-raw-image, edge-installer, edge-simplified-installer, edge-ami and edge-vsphere images support this customization.

[customizations]
fips = true

Architecture 🟤​

Select the target architecture the image should be built for. On premises, we don't support multi-arch builds. The architecture of the image is determined by the architecture of the host.

{
  "image_requests": [
    { "architecture": "x86_64" }
  ]
}

Installer 🔵 🟤​

Anaconda installer (ISO) image types support the following extra customizations.

[customizations.installer]
unattended = true
sudo-nopasswd = ["user", "%wheel"]
  • unattended: creates a kickstart file that makes the installation fully automatic. This includes setting the following options by default:
    • text display mode.
    • en_US.UTF-8 language/locale.
    • us keyboard layout.
    • UTC timezone.
    • zerombr, clearpart, and autopart to automatically wipe and partition the first disk.
    • network options to enable dhcp and auto-activation.

Or, in plain kickstart form:

liveimg --url file:///run/install/repo/liveimg.tar.gz
lang en_US.UTF-8
keyboard us
timezone UTC
zerombr
clearpart --all --initlabel
text
autopart --type=plain --fstype=xfs --nohome
reboot --eject
network --device=link --bootproto=dhcp --onboot=on --activate

Blueprint customizations that match the kickstart options (languages, keyboard, timezone) will change the value in the kickstart file as well.

  • sudo-nopasswd: adds a snippet to the kickstart file that, after installation, will create drop-in files in /etc/sudoers.d to allow the specified users and groups to run sudo without a password (groups must be prefixed with %). For example, setting the value to ["user", "%wheel"] will create the following kickstart %post section:
%post
echo -e "user\tALL=(ALL)\tNOPASSWD: ALL" > "/etc/sudoers.d/user"
chmod 0440 /etc/sudoers.d/user
echo -e "%wheel\tALL=(ALL)\tNOPASSWD: ALL" > "/etc/sudoers.d/%wheel"
chmod 0440 /etc/sudoers.d/%wheel
restorecon -rvF /etc/sudoers.d
%end

  • set the root ssh key
  • add the groups: widget, admin users and students
  • set the minimal size of root filesystem.
  • set the CIS Red Hat Enterprise Linux 8 Benchmark for Level 2 OpenSCAP profile.
