This repository has all that is needed to build docker images for the development and execution of the entire drudge stack. Note that the images are not (yet) optimized to be super lean for deployment, but rather for the convenience of development.
We start with the corebase image, which contains mostly the relatively stable
dependencies for the development of core C++ libraries like libcanon and
libparenth. Then in the base image, heavier dependencies, like Python and
JRE/Spark, not used in the core libraries are installed.
Then the drudge and gristmill projects are introduced as git submodules. Docker-compose in the root directory can be used to build all the images. Note that to build from scratch, it needs to be done in an order topologically sorted according to the dependency. Different from the base images, the Docker files for drudge and gristmill are actually maintained in their respective repositories, rather than here.
Note that inside the compose file, all the images are given tags in the
drudge repository in the root namespace without an explicit user. For
publishing into a remote registry, proper tagging is needed. Different stages
in the stack are tagged with plain name, with -latest omitted for
convenience. Specific versions will be marked when needed.
The docker repository
tschijnmo/drudge
has all its images built from here. The images without explicit version are
all based on the master branch of this repository, and shall be updated
whenever there is an update here.
In addition to being the platform to build docker images for drudge, this
repository can also serve as the ground for drudge development. The images can
be easily launched as services, with the source tree and a swap working
directory on the host machine mounted for convenience. For instance, to do
some drudge development, docker-compose up drudge can be followed by a
docker exec -it in the launched container to do the development. Changes to
the source code can immediately be visible. Unfortunately, setting tty: true, open_stdin: true still experiences hanging problems on some platforms and
cannot be used.
