To update the image to the latest version, you simply need to stop the image and start up a new instance with the latest code:
To stop and remove the old image, run the following commands:
docker stop gwweb
docker rm gwweb
Run the following command to pull down the latest webacc-ng image:
docker pull mfgroupwise/web
Rerun the docker run command you used in Downloading and Running the GroupWise Web image to use the same web-config file and certificates.
