Portainer allow user to deploy, configure, troubleshoot and secure containers in minutes on Kubernetes, Docker, Swarm and Nomad in any cloud, data center or device.

Prerequisite
#

Docker and Docker Compose must be up and running before deploying Portainer.

Run Portainer container
#

docker run -d \
    --publish 8000:8000 \
    --publish 9443:9443 \
    --name portainer \
    --restart=always \
    --volume /var/run/docker.sock:/var/run/docker.sock \
    --volume ${HOME}/docker/portainer_data:/data \
    portainer/portainer-ce:latest

Once installation is complete, you can log into your Portainer Server instance by opening a web browser and going to https://localhost:9443. You will be presented with the initial setup page for Portainer Server.

Optionally, you can also publish port 9000 to expose an insecure HTTP connection.

Auto-update running containers
#

If you want your containers to be always up-to-date, you can deploy Portainer alongside with Watchtower.

Watchtower will pull down your new image, gracefully shut down your existing container and restart it with the same options that were used when it was deployed initially.

Create a new docker-compose.yaml with following services definition:

version: "3.3"

services:
  portainer:
    container_name: portainer
    restart: unless-stopped
    ports:
      - "8000:8000"
      - "9443:9443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ${HOME}/docker/portainer_data:/data
    image: portainer/portainer-ce

  watchtower:
    container_name: watchtower
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    image: containrrr/watchtower

Then deploy and forget services:

docker-compose up --detach
