intelliJ ♥ Docker Tutorial

A short tutorial on how to use Docker within intelliJ and with a little help from Gradle.

Prerequisites

• install intelliJ Docker plugin

• install Docker Machine (https://docs.docker.com/machine/get-started)

• check that there is a default Docker Machine: docker-machine ps. If there is no default machine create one: docker-machine create --driver virtualbox default.

• start the default Docker Machine: docker-machine start default.

• bind the env vars to the shell: eval "$(docker-machine env default)"

• check if everything is correct: docker ps

Using Docker with intelliJ

1) Setup Docker cloud provider in intelliJ global preferences as shown below.

Tip	You can get the API URL by executing docker-machine ls and using the shown IP & port for the default machine.

2) Check connection to Docker daemon in intelliJ "Docker" tab

3) Create new project from version control using github (https://github.com/adersberger/intellij-docker-tutorial.git)

4) Create a new run configuration to deploy application to Docker as shown on the following screenshots:

Tip	Be sure not to forget to add the Gradle tasks as a "before launch" action as shown at the very bottom of the screenshot.

Tip	The same is also possible for Docker Compose files. Just point the "Deployment" dropdown to the Docker Compose file.

5) Run the configuration and inspect the Docker container. A browser will open automagically and point to the REST endpoint. Within intelliJ you can access the containers console output, environment variables, port bindings etc.

6) Celebrate!
