Docker and NetBeans

This section shows you basic Docker tooling with NetBeans:

• Pull/Build Docker images
• Run/Start/Stop Docker containers

NOTE: NetBeans only supports configuring Docker Engine running using Docker Toolbox. This means that if you are running Docker for Mac or Docker for Windows then NetBeans cannot be used.

Configure Docker Host

In “Services” window, right-click on “Docker”, click on “Add Docker...”

• Publish ports on Docker host interface (-P or -p in docker run command)

Click on “Next>” to see the options to configure exposed ports. Click on “Add” to explicitly map host port “8091” to container port “8091”.

Click on “Finish” to run the container. “Services” window is updated as:

Log is shown in the “Output” window:

Right-click on the container, select “Show Log” to show the log generated by the container. The container can be paused and stopped from here as well.
