在docker中保留数据-在docker中保留websphere应用程序

Question

I'm a beginner with docker...

I'm able to run a docker image with websphere and deploy a simple java application in it (just to test it).

docker run --name test -h test -p 9043:9043 -p 9443:9443 -d ibmcom/websphere-traditional

the container stars correctly so i can deploy my application through the whebsphere console.

When i stop the container, obviously, the data that i've putted in the websphere are lost.

docker stop test   
docker rm test

with docker stop test only, the data are not lost, but i need to switch off the docker machine at all( docker-machine stop , mine is a developer enviroment).

So i've tried to start the container with a volume....

docker run --name test -h test -p 9043:9043 -p 9443:9443 -d --mount source=myfirstvolume,destination=/myfirstvolumemounted ibmcom/websphere-traditional

bui i imagine, this isn't enough to permit the container to keep the application that i've installed in

Answer 1

When you docker run a container, you are creating an instance of that container from the specified image and starting it. Once you've created the container, you can simply docker start and docker stop the WebSphere App Server container without losing any of the WAS data that you've saved to the configuration repository, just as if you were running WAS outside a container. If you install an application to WAS and save the configuration, that application will still be installed after stopping and restarting the container.
