Java: Start WAS with Docker and deploy your own application

At the beginning

I started WebSphere on Docker and tried to deploy my own application

Docker settings

Creating a Dockerfile

Source on GitHub Image uses "websphere-liberty" If you place the war in / config / drops /, it will be deployed automatically, so set the war in the local folder where the war built with gradle is placed to be copied to the remote / config / drops /.

docker-compose.yml Source on GitHub There is nothing to consider

Creating a web module

Create gradle file

Source on GitHub Specify war for plugin and set the dependencies required for build

Java module

Source on GitHub

The response type of the app created in About SImple JAX-RS apps is changed to PLAN_TEXT.

Build-to-deploy flow

Create a war file with gradle's war task
Create a virtual environment on docker with docker-compose up -d (If it doesn't work, clear the cache with docker-compose build --no-cache)
Go to http: // localhost / MyWebApp / sample / Area (WAS seems to need to specify the name of the war file as the context root)

Execution result

Is displayed, it is confirmed that WAS is running safely!
