Simple dockerfile to install jsonnet-bundler and go-jsonnet into a runnable container.
You need to mount the jsonnet files to /src in the container. Existing
jsonnetfile.json dependencies will be installed and the jsonnet compiled. You
can pass extra arguments to jsonnet:
docker run --rm -it -v $(pwd):/src syseleven/jsonnet-builder ${ARGS}
If the jsonnetfile.json file is not directly located in the mounted folder
you can change the basedir with the BASEDIR argument. All entrypoint commands
(jb and jsonnet) will be relative to /src/${BASEDIR} (or ${BASEDIR} if
specified as absolute path).
Assuming you have the following structure
$ find .
one/
one/jsonnetfile.json
one/one.jsonnet
two/
two/two.jsonnet
If one.jsonnet imports ../two/two.jsonnet and you want to pass the -S
flag to the build, you can use the command
docker run --rm -it -v $(pwd):/src -e BASEDIR=one/ syseleven/jsonnet-builder -S one.jsonnet
