Hi, @ahl27. I noticed that your workshop wasn't launching and took a quick look. Orchestra uses a fixed image name. I've changed the image name to ghcr.io/ahl27/compgenomicsbioc2022:728221013 so your workshop should launch now. However, if you make changes or updates to the docker image, you'll either want to use the same tag or, better, use the tagging you are using now and add a :latest tag. If you go with the latter approach, let me know so that I can update Orchestra to use the :latest tag.
