Docker Proxy-gen

proxy-gen sets up a container running nginx and [docker-gen]. docker-gen generates a configs for nginx and reloads it when containers are started and stopped. The nginx config forward traffic to the dedicated container based on the hostname.

Usage

$ docker run -d -v /var/run/docker.sock:/var/run/docker.sock jderusse/proxy-gen

That is. You can now start yours containers and requesting it

$ docker run --name my_app -d nginx
$ curl http://my_app.docker

To automaticaly get the dns we recommand to use jderusse/dns-gen

You can customize the HOST name suffix by providing an env var HOST=subdomain.youdomain.com

$ docker run -d -e HOST=foo.docker -v /var/run/docker.sock:/var/run/docker.sock jderusse/proxy-gen
$ docker run --name my_app -d nginx
$ curl http://my_app.foo.docker

If you use docker_compose, you'd notice that containers are named with the following format project_service_number. You can simplify the full host name by telling proxy-gen to remove project or service from the host name

$ docker run -d -v /var/run/docker.sock:/var/run/docker.sock jderusse/proxy-gen
$ cd my_project
$ docker-composer up -d
$ curl http://my_project_app.docker

or

$ docker run -d -e SKIP_COMPOSE_PROJECT=1 -v /var/run/docker.sock:/var/run/docker.sock jderusse/proxy-gen
$ docker-composer up -d
$ curl http://app.docker

or

$ docker run -d -e SKIP_COMPOSE_SERVICE=1 -v /var/run/docker.sock:/var/run/docker.sock jderusse/proxy-gen
$ cd my_project
$ docker-composer up -d
$ curl http://my_project.docker
