docker pull openkbs/ubuntu-bionic-jdk-mvn-py3-x11

FROM openkbs/ubuntu-bionic-jdk-mvn-py3-x11

Then, you're ready to run:

• make sure you create your work directory, e.g., ./data

mkdir ./data
docker run -d --name my-ubuntu-bionic-jdk-mvn-py3-x11 -v $PWD/data:/data -i -t openkbs/ubuntu-bionic-jdk-mvn-py3-x11

Say, you will build the image "my/ubuntu-bionic-jdk-mvn-py3-x11".

docker build -t my/ubuntu-bionic-jdk-mvn-py3-x11 .

To run your own image, say, with some-ubuntu-bionic-jdk-mvn-py3-x11:

mkdir ./data
docker run -d --name some-ubuntu-bionic-jdk-mvn-py3-x11 -v $PWD/data:/data -i -t my/jdk-mvn-py3

docker exec -it some-ubuntu-bionic-jdk-mvn-py3-x11 /bin/bash

To run Python code

docker run -it --rm openkbs/ubuntu-bionic-jdk-mvn-py3-x11 python3 -c 'print("Hello World")'

or,

docker run -i --rm openkbs/ubuntu-bionic-jdk-mvn-py3-x11 python3 < myPyScript.py

or,

mkdir ./data
echo "print('Hello World')" > ./data/myPyScript.py
docker run -it --rm --name some-ubuntu-bionic-jdk-mvn-py3-x11 -v "$PWD"/data:/data openkbs/ubuntu-bionic-jdk-mvn-py3-x11 python3 myPyScript.py

or,

alias dpy3='docker run --rm openkbs/ubuntu-bionic-jdk-mvn-py3-x11 python3'
dpy3 -c 'print("Hello World")'

Remember, the default working directory, /data, inside the docker container -- treat is as "/". So, if you create subdirectory, "./data/workspace", in the host machine and the docker container will have it as "/data/workspace".

#!/bin/bash -x
mkdir ./data
cat >./data/HelloWorld.java <<-EOF
public class HelloWorld {
   public static void main(String[] args) {
      System.out.println("Hello, World");
   }
}
EOF
cat ./data/HelloWorld.java
alias djavac='docker run -it --rm --name some-ubuntu-bionic-jdk-mvn-py3-x11 -v '$PWD'/data:/data openkbs/ubuntu-bionic-jdk-mvn-py3-x11 javac'
alias djava='docker run -it --rm --name some-ubuntu-bionic-jdk-mvn-py3-x11 -v '$PWD'/data:/data openkbs/ubuntu-bionic-jdk-mvn-py3-x11 java'

djavac HelloWorld.java
djava HelloWorld

And, the output:

Hello, World

Hence, the alias above, "djavac" and "djava" is your docker-based "javac" and "java" commands and it will work the same way as your local installed Java's "javac" and "java" commands. However, for larger complex projects, you might want to consider to use Docker-based IDE.

• openkbs/eclipse-oxygen-docker
• openkbs/netbeans
• openkbs/scala-ide-docker
• openkbs/pycharm-docker
• openkbs/webstorm-docker
• openkbs/intellj-docker

• Java Development in Docker

• X11 Display with Xhost

You might see the warning message in the launching xterm console like below, you can just ignore it. I googles around and some blogs just suggested to ignore since the IDE still functional ok.
