The Dockerfile is provided as the basis for development and running
a thorough set of tests.
The general workflow is to use a combination of the Dockerfile and the
docker-compose.yml file.
The current image is builting using Alpine and associated perl packages
and other development packages.
The database engine is the one most recently installed by Alpine's package
manager apk under the name mariadb.
All Perl modules required by MySQL::Diff are installed, but MySQL::Diff
is not. Instead, the building of the Docker image is expected to be executed
and run from inside of the top level of the upstream git repository.
Given this assumption, the current working directory on the host computer is
mounted as /home/test/git/mysqldiff.
NOTE: This container is not intended to roll releases using Dist::Zilla - the
build would take a very long time and the image size would not worth it.
The Makefile.docker contains that actual docker build command, but to
run it:
$ make -f ./Makefile.docker
This will run a while.
Using docker-compose, launch the container in the background. To see what's
happing, inspect the docker-compose.yml file:
$ docker-compose up -d
See the container running (will be named mysqldiff):
$ docker ps
The following command will enter a running container named mysqldiff as the
test user and run the test suite:
$ make -f ./Makefile.docker test
$ make -f ./Makefile.docker shell
The only thing one must do is install Dist::Zilla while on the running container
as root:
$ docker exec -it mysqldiff sh (as root on container)$ cpanm Dist::Zilla
