Running Payara on Docker in Debug Mode

The Payara project provide a well maintained docker image on Docker Hub. Since version 5.192 you can easily create a docker image which runs Payara in Debug mode. You need just to add the environment variable “PAYARA_ARGS”

FROM payara/server-full:5.192
...
ENV PAYARA_ARGS --debug

COPY my-example.war $DEPLOY_DIR

Or you can also set the environment in your docker-compose.yml file:

version: "3.6"
services:
....  
  my-server:
    image: payara/server-full:5.192
    environment:
      PAYARA_ARGS: "--debug"
    ports:
      - "8080:8080"
      - "4848:4848"
      - "8181:8181"
      - "9009:9009"
....

After that Payara starts in Debug-Mode and listens to port 9009.
