Deploying Portainer behind nginx reverse proxy

Deploying in a Docker Standalone scenario

To deploy Portainer behind an nginx proxy in a Docker standalone scenario you must use a Docker Compose file. In the following docker-compose.yml you will find the configuration of the nginx proxy and the Portainer Server.

This example uses the excellent nginxproxy/nginx-proxy image as the proxy container, which requires no additional configuration beyond the two environment variables added to the portainer container's definition.

version: "2"

services:
  nginx-proxy:
    image: nginxproxy/nginx-proxy
    restart: always
    ports:
      - "80:80"
    volumes:
      - "/var/run/docker.sock:/tmp/docker.sock:ro"

  portainer:
    image: portainer/portainer-ee:lts
    command: -H unix:///var/run/docker.sock
    restart: always
    environment:
      - VIRTUAL_HOST=portainer.yourdomain.com
      - VIRTUAL_PORT=9000
    ports:
      - 8000:8000
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - portainer_data:/data

volumes:
  portainer_data:

To start working with this recipe, change the VIRTUAL_HOST value then deploy Portainer by running the following:

docker-compose up -d

When this has finished, run docker ps . You should see an output similar to this:

CONTAINER ID   IMAGE                           COMMAND                  CREATED         STATUS         PORTS                                                           NAMES

3e7c8b5d71d7   nginxproxy/nginx-proxy          "/app/docker-entrypo…"   4 minutes ago   Up 4 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp                               portainer_nginx-proxy_1

Once the deployment has finished you can browse portainer.yourdomain.com.

Deploying in a Docker Swarm scenario

Deploying Portainer in Docker Swarm behind nginx has similar steps to the Docker Standalone scenario. Before deploying, you need to create two elements: networks and volumes.

This deployment assumes you are running one manager node. If you are using multiple managers we advise reading this article before proceeding.

First, create two networks:

  • One for the agent and the communication with the Portainer Server.

  • One to 'expose' the Portainer container to the same network as the reverse proxy.

 docker network create -d overlay proxy
 docker network create -d overlay agent_network

Next, create the volume:

 docker volume create portainer_data

And finally, save the following recipe as portainer.yml:

version: '3.2'

services:
  nginx-proxy:
    image: nginxproxy/nginx-proxy
    networks:
      - proxy
    ports:
      - "80:80"
    volumes:
      - "/var/run/docker.sock:/tmp/docker.sock:ro"
      - "./vhost.d:/etc/nginx/vhost.d:ro"

  agent:
    image: portainer/agent:lts
    environment:
      # REQUIRED: Should be equal to the service name prefixed by "tasks." when
      # deployed inside an overlay network
      AGENT_CLUSTER_ADDR: tasks.agent
      # AGENT_PORT: 9001
      # LOG_LEVEL: DEBUG
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /var/lib/docker/volumes:/var/lib/docker/volumes
    networks:
      - agent_network
    deploy:
      mode: global
      placement:
        constraints: [node.platform.os == linux]

  portainer:
    image: portainer/portainer-ee:lts
    command: -H tcp://tasks.agent:9001 --tlsskipverify
    volumes:
      - data:/data
    environment:
      - VIRTUAL_HOST=portainer.yourdomain.com
      - VIRTUAL_PORT=9000
    ports:
      - 8000:8000
    networks:
      - proxy
      - agent_network
    deploy:
      mode: replicated
      replicas: 1
      placement:
        constraints: [node.role == manager]


networks:
  proxy:
    external: true
  agent_network:
    external: true

volumes:
   data:

To start working with this recipe, change the VIRTUAL_HOST value then deploy Portainer by running the following:

 docker stack deploy portainer -c portainer.yml

To check the deployment, run docker service ls. You should see an output similar to the following:

ID                  NAME                    MODE                REPLICAS            IMAGE                          PORTS
gy2bjxid0g4p        portainer_agent         global              1/1                 portainer/agent:lts
jwvjp5bux4sz        portainer_nginx-proxy   replicated          1/1                 nginxproxy/nginx-proxy:latest  *:80->80/tcp
5nflcvoxl3c7        portainer_portainer     replicated          1/1                 portainer/portainer-ee:lts     *:8000->8000/tcp

Once the services are running, you will be able to access Portainer from the URL you defined earlier, for example: portainer.yourdomain.com.
