What are the best practice to access a docker instances from the outside.
I'm planning to deploy several docker instances (node.js, php, mysql), either all packaged in one or through docker links between containers.
It is possible to control port on the host machine for each docker instances, but then what should be the best practice to access those instance from the outside. I would rather have subdomain only, and get rid of the forwarded port of the instance.
user@server:~/sandbox/docker-nginx$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3fc7c57ed66c docker-wordpress-nginx:latest /bin/bash /start.sh 3 days ago Up 3 days 0.0.0.0:49153->80/tcp evil_poincare
Expected behavior : Request wordpress.domain.com access the wordpress inside that docker instance, through the port 49153, but browser do not rewrite the Location with that port.
I had a look/tried several approaches, but none gave me that functionality :
- bouncy with routes.json files
- reverse proxying with nginx in host machine, but still have the port in the redirected url
- skydock sounds great but no multi host support yet
- pipework looks good also, but the disclaimer warn us that it should be provided by docker complex scenarios soon.
Any thoughts on that problem, and any recommendation on the best practice would be greatly appreciated, maybe I'm just missing something.
