Compile MailCleaner's build of Exim with Docker/Podman/etc.
The mc-exim package will be built from the GitHub source tree by checking out a tagged version of the Git repository. This requires the version to be provided as a commandline option, as described below, which matches an existing Git tag.
To build the package, you can use the one-step compose file or build and extract the package manually:
Run the build_and_extract.sh script with the target version as an option:
./build_and_extract.sh 4.97
you can optionally provide a destination directory as the second argument to have the .deb exported to a specific directory. By default, ${HOME}/debs/ will be used.
If successful, the path to the new .deb will be printed.
Note: docker will be used below, but note that other equivalent runtimes, such as podman which are compatible with the Dockerfile/Containerfile format can be substituted.
Below, the following option will be used:
${EXIM_VERSION}- The target tag version to be checked out from Git, which will also be used as the output file name. (default:4.97)
Build compilation container:
docker build --build-arg EXIM_VERSION=${EXIM_VERSION} -t build/mc-exim -f Containerfile
Run the container to get build results:
docker run -d build/mc-exim
the last line of the output will provide a hash ID which should be used as the CONTAINER_ID below.
Copy the .deb out of the container:
docker cp CONTAINER_ID:/mc-exim-${EXIM_VERSION}_amd64.deb /path/to/copy/to/
Clean up the container:
docker rm CONTAINER_ID
MailCleaner specific build options are defined in DEBIAN/EDITME. These need to be updated appropriately based on Exim changelogs (for new features, deprecations and renaming of options).
It would be best practice to increment the default version number within Containerfile and this document.
