While not official releases, the Apache Yetus project makes available two types of images available via
the GitHub Container Registry:
ghcr.io/apache/yetus-base
This image is the same as the 'built-in' Dockerfile when --docker is used without --dockerfile on the precommit command line. It includes all of the pre-requisites as needed by the various Apache Yetus components. It is located in precommit/src/main/shell/test-patch-docker/.
ghcr.io/apache/yetus
This image is the same as ghcr.io/aapache/yetus-base but includes a pre-built version of Apache Yetus as part of the base OS image. In other words, qbt, releasedocmaker, shelldocs, test-patch, etc., are in /usr/bin and available in the default path. It is generated from the Dockerfile located in the root of the source and is built with the options provided in the hooks directory.
Both images should be suitable to be used as a building block or even directly if your build environment needs no other dependencies. These images are especially useful for various CI systems that require a Docker image to be used.
Images are tagged such that 'main' represents the last successful Docker image build of the main branch. Images based off of the official source releases are tagged with a matching version number (e.g., 0.9.0). There is no 'latest' tagged image. It is recommended that users choose a stable tag so as not to be surprised by incompatible changes.
All of the executables that Apache Yetus provides requires access to one or more directories. These directories should be provided on the command line via the volume flags to docker run. For example, to run shelldocs against test-patch.sh:
docker run \
--rm \
-v /tmp/out:/output \
-v /src/precommit/src/main/shell:/input:ro \
ghcr.io/apache/yetus:0.14.0 \
shelldocs --output /output/test-patch.md --input /input/test-patch.sh
In this example, we mount two volumes: one for input (marked read-only), one for output. After execution, shelldocs has processed test-patch.sh and generated a test-patch.md file in /tmp/out on our local machine.
Precommit also works, assuming that Apache Yetus image has all of your project's dependencies. For example:
docker run \
--rm \
-v /tmp/patchdir:/patchdir \
-v /src:/basedir \
ghcr.io/apache/yetus:0.14.0 \
qbt \
--plugins=all \
--basedir=/basedir \
--patch-dir=/patchdir \
--project=yetus
If your project needs additional dependencies, it is trivial to build off of the Apache Yetus image:
FROM ghcr.io/apache/yetus:0.14.0
RUN apt-get -q update && apt-get -q install -y \
clang \
libssl-dev \
valgrind \
zlib1g-dev
docker build -t project/build:0.9.0 -f .
This example builds a docker image based off of Apache Yetus 0.9.0 but with the additions of clang, some development libraries, and valgrind. Now project/build:0.9.0 can be used instead of ghcr.io/apache/yetus:0.14.0 since it has all of Apache Yetus and the additions needed by our project.
test-patch and friends have direct support for Docker outside of the convenience images. That information is covered in-depth in theprecommit-docker section.
