I am trying to rebuild the discourse container to use a new config that puts discourse behind nginx (on the host). I run into the following error:

/usr/bin/docker: invalid reference format: repository name must be lowercase

Shell output

    /var/discourse# ./launcher rebuild app

What does your app.yml file look like? (make sure you remove your passwords before posting it publicly)

Thanks for the pointer! I was using an app.yml from this post and the edited portion looked like this:

# base templates used; can cut down to include less functionality per container templates:
  - "templates/cron.template.yml"
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/sshd.template.yml"
  - "templates/web.template.yml"
  - "templates/web.ratelimited.template.yml"
  - "templates/web.socketed.template.yml"

## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
expose:
#  - "80:80"   # http
#  - "443:443" # https

I managed to fix it by only changing the host ports in the generated app.yml and rebuilding:

templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/web.template.yml"
  - "templates/web.ratelimited.template.yml"
## Uncomment these two lines if you wish to add Lets Encrypt (https)
#  - "templates/web.ssl.template.yml"
#  - "templates/web.letsencrypt.ssl.template.yml"

I am using nginx to proxy the domain name to this port and can confirm it’s working.
