Attention! It's under strong development
State: Alpha
The purpose of this project is to provide an image of Sabayon docker-capable builder. It is just a Sabayon base with upgrades and compilation tools.
Images are also on Docker Hub sabayon/builder-amd64 sabayon/builder-amd64-squashed.
The docker container serves as a out-of-the-box builder for Sabayon.
The image will run a script that will check that all the deps of your specified atom are available on entropy, and installs them before compiling the actual package; then, it will emerge and build the packages and it's dependency that are not already available on the official sabayon repository
Ensure to have the daemon started and running:
sudo systemctl start docker
The container expect as arguments the commands to be executed to emerge, it acts like a wrapper with few enhancements.
For example, if you want to build app-text/tree
docker run -ti --rm sabayon/builder-amd64 app-text/tree
Or a package available in an overlay
docker run -ti --rm sabayon/builder-amd64 plasma-meta --layman kde
you can inspect the volumes mounted by docker, or mounting externally the output directories (in such case /usr/portage/distfiles)
docker run -ti --rm -v "$PWD"/artifacts:/usr/portage/packages sabayon/builder-amd64 app-text/tree
e.g. now you can find your tbz2 in your current directory, inside the "artifacts" folder
The -v flag can furthermore exploited and chained to obtain more fine-grained tweaks
You can of course customize it further, and replace all the configuration that's already been setup on the Docker Image.
- custom.unmask: will contain your unmasks
- custom.mask: will contain your masks
- custom.use: will contain your use flags
- custom.env: will contain your env specifications
- custom.keywords: will contain your keywords
Exporting those files to your container is a matter of adding an argument to your docker run command.
Example. Exporting your custom.unmask:
-v /my/path/custom.unmask:/opt/sabayon-build/conf/intel/portage/package.unmask/custom.unmask
Example. Exporting your custom.mask:
-v /my/path/custom.mask:/opt/sabayon-build/conf/intel/portage/package.mask/custom.mask
Example. Exporting your custom.use:
-v /my/path/custom.use:/opt/sabayon-build/conf/intel/portage/package.use/custom.use
Example. Exporting your custom.env:
-v /my/path/custom.env:/opt/sabayon-build/conf/intel/portage/package.env/custom.env
Example. Exporting your custom.keywords:
-v /my/path/custom.keywords:/opt/sabayon-build/conf/intel/portage/package.keywords/custom.keywords
In this way you tell to docker to mount your custom.* file inside /opt/sabayon-build/conf/intel/portage/package./custom. inside the container.
Keep in mind that the container have the portage directory located at /opt/sabayon-build/conf/intel/portage/ ; the /etc/portage folder is then symlinked to it.
Attention! Remember also to use absolute paths or docker will fail to mount your files in the container.
You can tweak the default behavior of the script setting those env variables with docker.
- BUILDER_PROFILE: Sets the profile for compilation, you can select it using the number or the name
- BUILDER_JOBS: How much jobs emerge will have assigned (-j option)
- PRESERVED_REBUILD: 1/0 to Enable/Disable preserved rebuild compilation
- EMERGE_DEFAULTS_ARGS: a list of commands that you might want to specify
- FEATURES: you can override default FEATURES (like in Portage's make.conf)
- ARTIFACTS_DIR: Copy emerge output files in this directory inside the container after all went as expected
Sabayon related:
- USE_EQUO: 1/0 Enable/Disable equo for installing the package dependencies (if you plan to use a pure gentoo repository, set it to 0, but the compilation process would be much longer)
- EQUO_INSTALL_ATOMS: Install the latest version of the dependency packages
- EQUO_INSTALL_VERSION: Install the specific version of the dependency packages
- EQUO_SPLIT_INSTALL: Install all the packages separately one by one
You can pass the ENV options to docker with the -e flag
docker run -e "EQUO_INSTALL_VERSION=1" -e "EQUO_INSTALL_ATOMS=0" -ti --rm -v "$PWD"/artifacts:/usr/portage/packages sabayon/builder-amd64 app-text/tree
Note: If you want to keep your container, remove the --rm option.
