0.8.1

Fixes

  • clean command now works properly.
  • If bender can't create a container, a useful error message is now being printed.

Features

  • Warn when you request a change to UID while running in rootless mode (user namespaces are tricky).
  • If an image build failed, bender tagged the image with a -failed suffix so it could be inspected further. Now bender also prepends timestamp so one image is not being overwritten over and over.

Minor

  • Improvements to documentation in README and --help output.

0.8.0

Thank you to all the contributors! You are awesome!

And special thanks to @kmehant, our Red Hat Open Source Contest 2019 student.

Features

  • You can now pass extra arguments to buildah from call when bender creates new build container. This can be done from CLI using --extra-buildah-from-args option of build command or in the playbook: vars → ansible-bender → buildah_from_extra_args. Thanks to @jordemort #140
  • One can print bender's version using -V/--version options.
  • The final image build by bender can now be squashed — all layers merged into one. This can be done with the --squash option or in the playbook: vars → ansible-bender → squash. @jordemort #154
  • Entrypoints now can be set! Aside from default container commands. Similar drill: --entrypoint or vars → ansible-bender → target_image → entrypoint, thanks you, @slopedog #155
  • Build times in list-builds are now more readable, enjoy! Thanks to @kmehant #161
  • Bender can now locate platform-python of RHEL 8 and CentOS 8, thanks to @hhenkel #171
  • When running bender in debug mode (--debug), ansible stdout callback plugin is set to debug (ANSIBLE_STDOUT_CALLBACK=debug). @kmehant #175
  • Ansible executes a playbook in the buildah container using buildah run command. Before bender gets to that point, it tries to create a no-op container (buildah from --name $container $base_image && buildah run $container true) first to verify that the container runtime is correctly set up. @kmehant #174
  • We have two new subcommands:
    • init — create a template playbook in the current working directory so you can get on-board bender's train more easily. @kmehant #184
    • clean — clean images from database which are no longer present on disk @kmehant #180

Bug fixes

  • Buildah 1.7.3 introduced a backwards-incompatible change to commit command which required changes in bender's code. Bender is now able to work with both: buildah < 1.7.3 and >= 1.7.3. CentOS 8.0 and RHEL 8.0 have buildah < 1.7.3.
  • Bender is using file locking when using its database (~/.cache/ab/db.json), the locks are now atomic thanks to @kmehant #176
  • When you set bender-specific variables in your playbook (vars → ansible-bender) and there is a typo in any of the variables or the variable is not recognized, bender exits and informs you about this problem — we have implemented this to prevent typos in the configuration so that you would not be able to build invalid images. @kmehant #189
  • Bender no longer prints output from buildah pull as errors. @kmehant #195

Minor

  • Contribution guide is now placed in the upstream repo.
  • You can now invoke ansible-bender directly from the upstream git repo using the common python way: 
    $ python3 -m ansible_bender --help
    @kmehant #160
  • Bender is now using Packit project for continuous integration.

0.7.0

Changes

  • Intermediate image layers are no longer tagged with a name. This was required by buildah, which is no longer the case since the 1.8 release. You can have the old behavior by adding verbose_layer_names: true to the root of the configuration.

Bug fixes

  • list-builds should no longer error out after an upgrade.
  • Bender incorrectly printed output of buildah inspect $base_image which cluttered the output a lot - that's no longer the case.

0.6.1

Bug fixes

  • Make bender work with ansible 2.8.

Minor

  • Test bender in vagrant VMs against ansible 2.7 and 2.8.

0.6.0

Features

  • You can specify a user to be used during the build process (--build-user). (Thanks to @11mariom #122)

Bug fixes

  • Bender is able to correctly process multiple build volumes. (Thanks to @11mariom #118)

0.5.3

Thank you for contributions from @jamescassell and @alexgarel!

Bug fixes

  • Bender now correctly picks up all cached layers and does not display an error message: Error: could not get runtime: error creating runtime static files directory /var/lib/containers/storage/libpod: mkdir /var/lib/containers/storage/libpod: permission denied. This was coming from podman so we switched to buildah to perform checks for presence of layers.
  • A name of a working container now contains month digits instead of minutes as one would expect. (How come that no one noticed?)

Minor

  • README now contains a bit of documentation for limitations of rootless mode.

0.5.2

Bug fixes

Minor

  • Document how to make Ansible roles available during a build if they are on a custom path.

0.5.1

Bug fixes

  • When pushing a build using the push command, bender now picks the correct image with metadata, instead of the last layer.
  • Variables are now expanded recursively. This means that when you define a variable in vars section, you can use it in other variables.

Minor

  • Documentation updates.

0.5.0

Breaking changes

  • Option --labels was renamed to --label to match other container tooling.

Features

  • Ansible-bender can now be configured using Ansible variables. For more info, please read the documentation
    • Given this change, base image and target image name are now optional arguments of the build command.
  • Bender now uses more candidates when searching for python interpreter in the base image, namely /usr/bin/python3.7 and so on.
  • You can now set annotations on the target image.
  • When bender invokes a playbook against a container, it now changes hosts variable (in a copy), so that it's not accidentally executed in localhost environment.
  • Json schema is now used to validate input.
  • Before starting the build process, bender checks if the container backend works.

Bug fixes

  • When ansible-playbook command uses python 2, bender refuses to continue since the build will not work.
  • Errors are now being properly logged when bender looks for python interpreter in the base image.
  • There was a need for a compatibility fix with buildah 1.7.
  • A build will terminate if there was an exception thrown during the caching or layering process.
  • Bender will not try to load non-existent layers from cache.

0.4.0

Ansible-bender now uses Azure Pipelines as a CI system.

Features

  • There were updates to documentation in README:
    • Info about vfs and overlay buildah storage backends.
    • Rootless containers.
    • How you can use base images with python2.
    • Requirements of ansible-bender.
  • Bender now produces a more clear message when a base image doesn't have a python interpreter.
  • You are now able to pass path to the python interpreter inside the base image via CLI.

Bug fixes

  • Bender now uses more buildah commands instead of podman.
  • If bender is invoked with a non-root user, the ansible-playbook session is now wrapped with buildah unshare.
  • Don't print to error log when an image is being pulled.

0.3.2

I experimented with running ansible-bender inside an OpenShift pod. Details can be found in a Makefile and in the contrib/ directory.

Bug fixes

  • Ansible-bender is now able to pull base images properly again if they are not present before a build.
  • podman is now used to perform inspect.
  • Working container name was improved to be more safe.

0.3.1

Breaking changes

  • Since our executable, ab, conflicted with a binary from httpd package, I decided to rename it to ansible-bender. Please add a shell alias if you want ab back.

Features

  • You can pass extra arguments to ansible-playbook command via --ansible-extra-args=. Use it with caution!
  • Python packaging was improved, thanks to great help from @webknjaz

Bug fixes

  • Ansible-bender now correctly processes build volumes even when a layer is loaded from cache.

0.3.0

Features

  • There is a new command available: push. You can push the images you built to remote locations. This is built on top of podman push command, for more info please see manpages podman-push(1) or skopeo(1).
  • Inspecting a build now produces more info: playbook path, ID of the image, build volumes.

Bug fixes

  • For file-related actions, when ansible reports changed=False, the respective layer will be now loaded from cache.

0.2.1

Bug fixes

  • Correctly recreate working container when loading a layer from cache.
  • When ab is installed using pip on Fedora 29, it wasn't able to import itself when invoked from the callback plugin. This is now resolved.

0.2.0

Renamed to ansible-bender, the binary name was left intact.

Features

  • Failed builds are commited as -failed.
  • The tool tries to find python interpreter inside the base image.
  • Added command list-builds.
  • Added command get-logs.
  • Added command inspect.
  • Implemented a caching mechanism:
    • Limitation of caching are file tasks: ansible can't detect that a file wasn't changed and reports it changed. This means that ab is not able to load such result from cache.
    • Caching can be controled by a tag no-cache which you can put into a task.
  • You can disable layering either by build's option --no-cache or adding a tag stop-Layering to a task.
  • Multiple user experience, output, polish changes.

0.1.0

Initial release!

Features

  • You can build your container images with buildah as a backend.
  • You are able to set various image metadata via CLI:
    • working directory
    • environment variables
    • labels
    • user
    • default command
    • exposed ports
  • You can do volume mounts during build.
