ansible-role-docker-web-server

This sets up a Docker web server on a CentOS 7 host with the following features:

• Uses the jwilder/nginx-proxy container as the front-end proxy, which allows for automatic configuration of virtual hosts by environment variables.
• Optionally uses the JrCs/docker-letsencrypt-nginx-proxy-companion container for LetsEncrypt, which allows for automatic issuance & renewals of LetsEncrypt certificates, configured with environment variables. It also automatically updates the vhosts in the nginx-proxy container with the configuration for the certificates. (when docker_web_setup_https_container: true)
• Automatically pulls a repository from Git container a docker-compose file (or other script) which is used to configure the containers and environment variables.
  • It uses an SSH deploy key to accomplish this.
