Building the main process inside Docker container

This source code was created for a Hungarian Youtube tutorial. For english links, please check the release list or the latest version of this readme. It demonstrates how you can build the main process (the first process with 1 as PID) inside a Docker container using SHELL, ENTRYPOINT and CMD and how the RUN instruction is similar to the others.

Note: The tutorial requires jq and recent Bash version installed on your machine.

Each Dockerfile has a version number. You can run the tests one by one using build.sh and run.sh passing the version as the first argument to each script.

./build.sh v1
./run.sh v1

Pass a command optionally as the second argument

./run.sh v1 'echo "Hello Docker"'

Run all tests using test-all.sh

./test-all.sh

You can also list the already created containers:

./list.sh

Or delete everything with reset.sh

./reset.sh

NOTE: This script will deletes containers and images created by the tests. It uses open container annotations to identify whether the container was created by this project and will fail if the required label is not found or the repository stored as image source is different. If you had an existing container with the same name (not likely), you can export an environment variable in your terminal to override the default container prefix which is "command":

export CONTAINER_NAME_PREFIX=mycommand
