Web in continuous restart loop, can't connect to server #41

Closed tony closed 7 years ago

Related #19

I notice something at https://github.com/mjhea0 pointing to https://github.com/docker/compose/issues/1013.

I don't have a clue what's really happening in that thread.

MacOS Sierra 10.12.2 (16C67) ef08c89

Frustratingly, the servers for dockerizingdjango_web_run_5 keep restarting, even after docker-compose kill

~/work/django/dockerizing-django master
❯ docker-compose kill
Killing dockerizingdjango_nginx_1 ... done
Killing dockerizingdjango_web_1 ... done

dockerizingdjango_redis_1      docker-entrypoint.sh redis ...   Exit 137

dockerizingdjango_web_run_5    /usr/local/bin/python mana ...   Restarting   8000/tcp

Any hints as to why there is a restart loop and what I can do to get more debug info would be helpful. That way I can provide a bit more details.

❯ docker ps

Okay I understand better now.

I wasn't sourcing the docker-machine: eval $(docker-machine env machine-name)
