I’ve completed the steps for the docker install. However, I’m unable to connect to the Discourse application from the outside world or host machine. (E.g. telnet localhost 8001 fails.)
In my app.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:
- "8001:80" # http
# - "443:443" # https
Performing ./launcher rebuild app indicates this docker command:
usr/bin/docker run -d --restart=always -e LANG=en_US.UTF-8 -e RAILS_ENV=production -e UNICORN_WORKERS=4 -e UNICORN_SIDEKIQS=1 -e RUBY_GC_MALLOC_LIMIT=40000000 -e RUBY_HEAP_MIN_SLOTS=800000 -e DISCOURSE_DB_SOCKET=/var/run/postgresql -e DISCOURSE_DB_HOST= -e DISCOURSE_DB_PORT= -e DISCOURSE_HOSTNAME=************* -e DISCOURSE_DEVELOPER_EMAILS=***************** -e DISCOURSE_SMTP_ADDRESS=************** -e DISCOURSE_SMTP_USER_NAME=******************* -e DISCOURSE_SMTP_PASSWORD=************* -e LETSENCRYPT_ACCOUNT_EMAIL=********* -h jupiter-app -e DOCKER_HOST_IP=172.17.0.1 --name app -t -v /var/discourse/shared/standalone:/shared -v /var/discourse/shared/standalone/log/var-log:/var/log local_discourse/app /sbin/boot
The docker command appears to missing any expose or port command switch, so I checked docker ps:
admin@jupiter:/var/discourse(master)$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
07b612f1f4fc local_discourse/app "/sbin/boot" 18 minutes ago Up 13 minutes app
This shows there are no ports exposed?
Finally, to verify Discourse was in fact working inside the host I performed ./launcher enter app:
root@jupiter-app:/var/www/discourse# wget localhost:80
--2016-04-27 18:31:20-- http://localhost/

Any ideas? Thanks!
