2. Perform virtual image boot

(1) Execution in interactive mode

Execute the following command

docker run -it websphere-liberty

(2) Execution in background mode

Execute the following command

docker run -d -p 80:9080 --name wlp websphere-liberty

(3) Check the log

Execute the following command

docker logs --tail=all -f wlp

(4) Check the IP address

I was asked for a password for [email protected] that I don't remember setting, and it didn't work. It can't be helped, so I put WinSCP and put SCP, and I was able to upload the file to the virtual environment successfully.

2. Deploy the application

Execute the following command

docker run -d -p 80:9080 --name=app -v /tmp/ServletApp.war:/config/dropins/app.war websphere-liberty
