This would usually indicate you are trying to set the user/group of the mod_wsgi daemon process with a user or group that doesn’t exist inside of the Docker image. I seriously would advise against you trying to construct your own Docker image. Creating Docker images properly that follow best practices, especially if trying to run Apache is non trivial. For now I would suggest you use my base image: * https://github.com/GrahamDumpleton/mod_wsgi-docker <https://github.com/GrahamDumpleton/mod_wsgi-docker> I have an even better base image than this one which can do a lot more and security wise is much better, but not yet ready to let people use the newer one. So try the grahamdumpleton/mod-wsgi-docker ones first. If you think that creating Docker images is trivial, you might want to read some of my blog posts about some of the issues you need to deal with. * http://blog.dscpl.com.au/2016/01/roundup-of-docker-issues-when-hosting.html <http://blog.dscpl.com.au/2016/01/roundup-of-docker-issues-when-hosting.html> The image above I reference doesn’t adhere to all the things one should do, but the newer one will and more.
