⁠Nginx reverse proxy with ssl termination for rancher server

maintained by codedevote

• RANCHER_URL

• default: localhost

• RANCHER_PORT

• default: 8080

• RANCHER_CONTAINER_NAME

• default: rancher

⁠Running codedevote/nginx-ssl-proxy-rancher container

All the information on running the base image also applies to this container.

⁠Assumptions

• Since the nginx container needs to communicate with the rancher container, you need to make sure, there is a link between those two containers. You can either use the (deprecated) --link option to link the rancher container to the nginx container or you put both containers on a docker network (by creating one useing docker network create). There seems to be an issue (see #2) using the default docker bridge network, so make sure, you create a dedicated network and hook both containers to this network by adding the --net option to your docker run command.
• The rancher server can be reached from nginx container on the docker network at http://$RANCHER_CONTAINER_NAME:$RANCHER_PORT (for information on how to setup a rancher server refer to https://github.com/rancher/rancher⁠).
• You bind-mount a directory to /etc/nginx/external with the following minimum contents:
• SSL certificate (chained for intermediate CAs) in a file called cert.pem
• Private key in a file called key.pem
• You can also put a dh.pem file here (see base image docs). If not, one will be created on first start.
