Setup for composing an image
The new output type must add a kickstart template to ./share/composer/ where the name of the kickstart (without the trailing .ks) matches the entry in compose_args.
The kickstart should not have any url or repo entries, these will be added at build time. The %packages section should be the last thing, and while it can contain mandatory packages required by the output type, it should not have the trailing %end because the package NEVRAs will be appended to it at build time.
compose_args should have a name matching the kickstart, and it should set the novirt_install parameters needed to generate the desired output. Other types should be set to False.

Setup v0 of the API server
v0_api() must be called to setup the API routes for Flask
Some requests only return a status/error response.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Example response:
{ "status": true }Error response:
{ "errors": ["ggit-error: Failed to remove entry. File isn't in the tree - jboss.toml (-1)"] "status": false }
All of the blueprints routes support the optional branch argument. If it is not used then the API will use the master branch for blueprints. If you want to create a new branch use the new or workspace routes with ?branch=<branch-name> to store the new blueprint on the new branch.
List the available blueprints:
{ "limit": 20, "offset": 0, "blueprints": [ "atlas", "development", "glusterfs", "http-server", "jboss", "kubernetes" ], "total": 6 }
Return the JSON representation of the blueprint. This includes 3 top level objects. changes which lists whether or not the workspace is different from the most recent commit. blueprints which lists the JSON representation of the blueprint, and errors which will list any errors, like non-existant blueprints.
Example:
{ "changes": [ { "changed": false, "name": "glusterfs" } ], "errors": [], "blueprints": [ { "description": "An example GlusterFS server with samba", "modules": [ { "name": "glusterfs", "version": "3.7.*" }, { "name": "glusterfs-cli", "version": "3.7.*" } ], "name": "glusterfs", "packages": [ { "name": "2ping", "version": "3.2.1" }, { "name": "samba", "version": "4.2.*" } ], "version": "0.0.6" } ] }Error example:
{ "changes": [], "errors": ["ggit-error: the path 'missing.toml' does not exist in the given tree (-3)"] "blueprints": [] }
Return the commits to a blueprint. By default it returns the first 20 commits, this can be changed by passing offset and/or limit. The response will include the commit hash, summary, timestamp, and optionally the revision number. The commit hash can be passed to /api/v0/blueprints/diff/ to retrieve the exact changes.
Example:
{ "errors": [], "limit": 20, "offset": 0, "blueprints": [ { "changes": [ { "commit": "e083921a7ed1cf2eec91ad12b9ad1e70ef3470be", "message": "blueprint glusterfs, version 0.0.6 saved.", "revision": null, "timestamp": "2017-11-23T00:18:13Z" }, { "commit": "cee5f4c20fc33ea4d54bfecf56f4ad41ad15f4f3", "message": "blueprint glusterfs, version 0.0.5 saved.", "revision": null, "timestamp": "2017-11-11T01:00:28Z" }, { "commit": "29b492f26ed35d80800b536623bafc51e2f0eff2", "message": "blueprint glusterfs, version 0.0.4 saved.", "revision": null, "timestamp": "2017-11-11T00:28:30Z" }, { "commit": "03374adbf080fe34f5c6c29f2e49cc2b86958bf2", "message": "blueprint glusterfs, version 0.0.3 saved.", "revision": null, "timestamp": "2017-11-10T23:15:52Z" }, { "commit": "0e08ecbb708675bfabc82952599a1712a843779d", "message": "blueprint glusterfs, version 0.0.2 saved.", "revision": null, "timestamp": "2017-11-10T23:14:56Z" }, { "commit": "3e11eb87a63d289662cba4b1804a0947a6843379", "message": "blueprint glusterfs, version 0.0.1 saved.", "revision": null, "timestamp": "2017-11-08T00:02:47Z" } ], "name": "glusterfs", "total": 6 } ] }
Create a new blueprint, or update an existing blueprint. This supports both JSON and TOML for the blueprint format. The blueprint should be in the body of the request with the Content-Type header set to either application/json or text/x-toml.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Delete a blueprint. The blueprint is deleted from the branch, and will no longer be listed by the list route. A blueprint can be undeleted using the undo route to revert to a previous commit.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Write a blueprint to the temporary workspace. This works exactly the same as new except that it does not create a commit. JSON and TOML bodies are supported.
The workspace is meant to be used as a temporary blueprint storage for clients. It will be read by the info and diff routes if it is different from the most recent commit.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Remove the temporary workspace copy of a blueprint. The info route will now return the most recent commit of the blueprint. Any changes that were in the workspace will be lost.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
This will revert the blueprint to a previous commit. The commit hash from the changes route can be used in this request.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Tag a blueprint as a new release. This uses git tags with a special format. refs/tags/<branch>/<filename>/r<revision>. Only the most recent blueprint commit can be tagged. Revisions start at 1 and increment for each new tag (per-blueprint). If the commit has already been tagged it will return false.
The response will be a status response with status set to true, or an error response with it set to false and an error message included.
Return the differences between two commits, or the workspace. The commit hash from the changes response can be used here, or several special strings:
- NEWEST will select the newest git commit. This works for from_commit or to_commit
- WORKSPACE will select the workspace copy. This can only be used in to_commit
eg. /api/v0/blueprints/diff/glusterfs/NEWEST/WORKSPACE will return the differences between the most recent git commit and the contents of the workspace.
Each entry in the response’s diff object contains the old blueprint value and the new one. If old is null and new is set, then it was added. If new is null and old is set, then it was removed. If both are set, then it was changed.
The old/new entries will have the name of the blueprint field that was changed. This can be one of: Name, Description, Version, Module, or Package. The contents for these will be the old/new values for them.
In the example below the version was changed and the ping package was added.
Example:
{ "diff": [ { "new": { "Version": "0.0.6" }, "old": { "Version": "0.0.5" } }, { "new": { "Package": { "name": "ping", "version": "3.2.1" } }, "old": null } ] }
Return a JSON representation of the blueprint with the package and module versions set to the exact versions chosen by depsolving the blueprint.
Example:
{ "errors": [], "blueprints": [ { "blueprint": { "description": "An example GlusterFS server with samba", "modules": [ { "name": "glusterfs", "version": "3.8.4-18.4.el7.x86_64" }, { "name": "glusterfs-cli", "version": "3.8.4-18.4.el7.x86_64" } ], "name": "glusterfs", "packages": [ { "name": "ping", "version": "2:3.2.1-2.el7.noarch" }, { "name": "samba", "version": "4.6.2-8.el7.x86_64" } ], "version": "0.0.6" } } ] }
Depsolve the blueprint using yum, return the blueprint used, and the NEVRAs of the packages chosen to satisfy the blueprint’s requirements. The response will include a list of results, with the full dependency list in dependencies, the NEVRAs for the blueprint’s direct modules and packages in modules, and any error will be in errors.
Example:
{ "errors": [], "blueprints": [ { "dependencies": [ { "arch": "noarch", "epoch": "0", "name": "2ping", "release": "2.el7", "version": "3.2.1" }, { "arch": "x86_64", "epoch": "0", "name": "acl", "release": "12.el7", "version": "2.2.51" }, { "arch": "x86_64", "epoch": "0", "name": "audit-libs", "release": "3.el7", "version": "2.7.6" }, { "arch": "x86_64", "epoch": "0", "name": "avahi-libs", "release": "17.el7", "version": "0.6.31" }, ... ], "modules": [ { "arch": "noarch", "epoch": "0", "name": "2ping", "release": "2.el7", "version": "3.2.1" }, { "arch": "x86_64", "epoch": "0", "name": "glusterfs", "release": "18.4.el7", "version": "3.8.4" }, ... ], "blueprint": { "description": "An example GlusterFS server with samba", "modules": [ { "name": "glusterfs", "version": "3.7.*" }, ... } } ] }
List all of the available projects. By default this returns the first 20 items, but this can be changed by setting the offset and limit arguments.
Example:
{ "limit": 20, "offset": 0, "projects": [ { "description": "0 A.D. (pronounced "zero ey-dee") is a ...", "homepage": "http://play0ad.com", "name": "0ad", "summary": "Cross-Platform RTS Game of Ancient Warfare", "upstream_vcs": "UPSTREAM_VCS" }, ... ], "total": 21770 }
Return information about the comma-separated list of projects. It includes the description of the package along with the list of available builds.
Example:
{ "projects": [ { "builds": [ { "arch": "x86_64", "build_config_ref": "BUILD_CONFIG_REF", "build_env_ref": "BUILD_ENV_REF", "build_time": "2017-03-01T08:39:23", "changelog": "- restore incremental backups correctly, files ...", "epoch": "2", "metadata": {}, "release": "32.el7", "source": { "license": "GPLv3+", "metadata": {}, "source_ref": "SOURCE_REF", "version": "1.26" } } ], "description": "The GNU tar program saves many ...", "homepage": "http://www.gnu.org/software/tar/", "name": "tar", "summary": "A GNU file archiving program", "upstream_vcs": "UPSTREAM_VCS" } ] }

Get detailed information about the compose. The returned JSON string will contain the following information:
- id - The uuid of the comoposition
- config - containing the configuration settings used to run Anaconda
- blueprint - The depsolved blueprint used to generate the kickstart
- commit - The (local) git commit hash for the blueprint used
- deps - The NEVRA of all of the dependencies used in the composition
- compose_type - The type of output generated (tar, iso, etc.)
- queue_status - The final status of the composition (FINISHED or FAILED)
Example:
{ "commit": "7078e521a54b12eae31c3fd028680da7a0815a4d", "compose_type": "tar", "config": { "anaconda_args": "", "armplatform": "", "compress_args": [], "compression": "xz", "image_name": "root.tar.xz", ... }, "deps": { "packages": [ { "arch": "x86_64", "epoch": "0", "name": "acl", "release": "14.el7", "version": "2.2.51" } ] }, "id": "c30b7d80-523b-4a23-ad52-61b799739ce8", "queue_status": "FINISHED", "blueprint": { "description": "An example kubernetes master", ... } }
Returns a .tar of the metadata used for the build. This includes all the information needed to reproduce the build, including the final kickstart populated with repository and package NEVRA.
The mime type is set to ‘application/x-tar’ and the filename is set to UUID-metadata.tar
The .tar is uncompressed, but is not large.
Returns a .tar of the metadata, logs, and output image of the build. This includes all the information needed to reproduce the build, including the final kickstart populated with repository and package NEVRA. The output image is already in compressed form so the returned tar is not compressed.
The mime type is set to ‘application/x-tar’ and the filename is set to UUID.tar
Returns a .tar of the anaconda build logs. The tar is not compressed, but is not large.
The mime type is set to ‘application/x-tar’ and the filename is set to UUID-logs.tar
Returns the output image from the build. The filename is set to the filename from the build with the UUID as a prefix. eg. UUID-root.tar.xz or UUID-boot.iso.
Returns the end of the anaconda.log. The size parameter is optional and defaults to 1Mbytes if it is not included. The returned data is raw text from the end of the logfile, starting on a line boundry.
