vidbina/scala-dev-env repository overview

⁠Scala Development Container

Used this container to run through the Functional Programming Principles in Scala⁠ course by Martin Odersky⁠.

If you are unfamiliar with docker the documentation provided by Docker⁠ may help to get you started.

Assuming that you want to work on a project at the path $PROJECT_PATH and you already have docker installed you may run the container using

docker run -it vidbina/scala-dev-env:latest -v $PROJECT_PATH:/src

The directory $PROJECT_PATH will be mounted in /src and the terminal will drop into an sbt session right away. If you don't want to be dropped into sbt, specify the entrypoint of choice. The entrypoint chosen below is /bin/bash which should drop you into a trusty old bash session.

docker run -it vidbina/scala-dev-env:latest -v $PROJECT_PATH:/src /bin/bash

Since containers are stateless any work done while the container is running will not be persisted unless

• the changes are made on a mounted volume, in which case all changes are not really happening in the container but directory on the source directory in the host filesystem, or
• the changes are committed.

Since sbt will most likely pull some packages the first time you start sbt in a new project, you may want to commit the results by opening a new terminal session while the container is still running and executing docker commit $NAME_OF_HASH_OF_THE_CONTAINER $COMMITED_IMAGE_NAME[:$TAG].

Since I use this container to walk through the Scala course by Martin Odersky I commit my environments by exercise e.g.: docker commit $SOME_HASH vidbina/scala-dev-env:ex-2.
