WebSphere Liberty Profile on Docker - An update

In the context of my current project, we were talking about running WebSphere Liberty Profile on Docker, so here's an update: -

Start a container

- Note that we're using the -v ( aka --volumes ) switch to make a local WAR file available to the container
- Note that we're also mapping ports using -p and running the container as a daemon ( -d )

docker run -d -p 80:9080 -p 443:9443 -v /tmp/ferret-1.2.war:/config/dropins/ferret-1.2.war websphere-liberty:latest


- Note that the container ID is in full; the short version is 4823dd0bc7a6 as will be seen later using docker ps -a

Check the container logs

docker logs 4823dd0bc7a690a1ae6eafce6a0a8611fdf4cc73f6beadd6436c67c1a4838231

Look at the running Docker container(s)

docker ps -a

Open a shell to the container

docker exec -i -t 4823dd0bc7a6 /bin/bash


Examine the detailed Liberty messages

default@4823dd0bc7a6:/$ cat logs/messages.log 

Check the Liberty version

default@4823dd0bc7a6:/$ /opt/ibm/wlp/bin/server version

Exit the shell

default@4823dd0bc7a6:/$ exit

Stop the container

docker stop 4823dd0bc7a6


Remove the container

docker rm 4823dd0bc7a6
