Docker build instructions

[IsabelMarleen]

While I was editing the instructions for the python installation, I tried following the docker instructions to be thorough and I could not build the image. I ran docker run --publish 8098:5000 --detach --name submit-plug synbiohub/plugin-submit-excel2sbol:snapshot in the command line and the download and pull processes work fine, but the starting produces the following error:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "waitress-serve": executable file not found in $PATH: unknown.

I checked and the path to an executable waitress-serve is in my PATH variable. I haven't used docker in a while, but I was able to build and run test-images. Updating docker made no difference. Are any additional setup steps required or could there be another issue on my end?
