Docker Nginx Setup

Prerequisites

• Docker Engine
  • if not installed, then run install script with root privileges
    • sudo ./install-docker-with-compose.sh
    • (will install latest docker engine and docker-compose 1.11.2)

Setup

Scripted

• run install script with root privileges
  • sudo ./install.sh

Manual

• copy docker-nginx directory to /etc/
  • make sure it looks like this:

/etc/docker-nginx
  |-certs
  |  \-{empty directory}
  |-docker-nginx.sh
  \-nginx.tmpl

• copy docker-nginx.service to /etc/systemd/system/
• reload sytemd
  • systemctl daemon-reload
• test service
  • systemctl start docker-nginx.service
  • docker ps -a -f name=nginx - should list 3 running containers
  • for potential debugging look at systemctl status docker-nginx.service
• enable service for autostart
  • systemctl enable docker-nginx.service

Usage

• start/stop the containers
   - systemctl (start|stop) docker-nginx.service
• start a reachabel container

docker run -d \
  --name whoami-sample \
  -e "VIRTUAL_HOST=whoami.sample.eu" \
  -e "LETSENCRYPT_HOST=whoami.sample.eu" \
  -e "LETSENCRYPT_EMAIL=admin@sample.eu" \
  jwilder/whoami

• to enable CORS-Requests add -e "ALLOW_CORS=true" \
• for test cases add -e "LETSENCRYPT_TEST=true" \ to get a self signed certificate
  • useful to work around the certs/week limits of Let's Encrypt
