Hi @dustin-davis_2758 , I'm not really sure - I'm not familiar enough with ADO Docker Compose to help :/ The error is coming because the container repository (image) name is incorrect; it should be like proget.initech.com/feedName/initech/repositoryName Generally you put this in your docker-compose.yml file, like this: https://docs.inedo.com/docs/docker-compose-installation-guide#example-docker-compose-configuration-file So that would be the first place I would look. If you have the proper image name in there, tehn I guess, ADO might be doing something different? Let us know what you find! Cheers, Alana
