How to run a specific profile on WebSphere on Docker?

Question

Is it possible to copy an existing WebSphere profile and run it on WebSphere in Docker?

I am doing some research on containerization, virtualization, etc. and am currently working with Docker. Getting WebSphere up and running on Docker is simple enough:

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

What I'd like to do is use a profile from another WebSphere instance and run that on the Docker WebSphere. I have tried to do the following in an attempt to mount a directory that contains the profile in question, and to run same:

docker run -v /opt/WebSphere/WAS8_5/:/WASDIR --name myprofileserver -h myprofileserver -p 9043:9043 -p 9443:9443 -d ibmcom/websphere-traditional:install -e PROFILE_NAME=/WASDIR/profiles/myprofile1

The end result of this command is that the container is created, but does not run:

docker: Error response from daemon: oci runtime error: exec: "-e": executable file not found in $PATH

Perhaps there is a switch, setup, or other configuration I am missing here?

The last argument to docker run is the command you want to run inside the container (or the name of the image if you're running the default entrypoint / cmd). You just need to move your environment variable definition back in the command like this:

docker run -v /opt/WebSphere/WAS8_5/:/WASDIR --name myprofileserver -h myprofileserver -p 9043:9043 -p 9443:9443 -d -e PROFILE_NAME=/WASDIR/profiles/myprofile1 ibmcom/websphere-traditional:install
