In this tutorial, you will learn how to install Portainer on Ubuntu 22.04. Portainer is a self-service container service delivery platform that provides container management GUI for Kubernetes, Docker and Swarm.

Install Portainer on Ubuntu 22.04

Portainer is available as both Community Edition and Business Edition. We will be installing the Community Edition in this guide.

There are different environments in which you can deploy Portainer;

  1. Standalone Docker container
  2. Docker Swarm
  3. Kubernetes

In this tutorial, we will learn how to install Portainer on Ubuntu 22.04 as a standalone Docker container.

You can also check how to setup Portainer with SSL certificates by following the link below;

Setup Portainer with SSL Certificates

Install Docker on Ubuntu 22.04

To begin with, you need to install Docker on Ubuntu 22.04 by running the commands below;

curl -fsSL https://download.docker.com/linux/ubuntu/gpg \
| sudo gpg --dearmor > /etc/apt/trusted.gpg.d/docker.gpg
echo \
"deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" \
| sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
apt update
sudo apt install docker-ce docker-ce-cli containerd.io

Start and enable Docker to run on system boot;

systemctl enable --now docker

Create Portainer Server Docker Data Volume

Once the Docker is in place, it is now time to deploy Portainer on Ubuntu 22.04.

To begin with, you need to create Portainer server data volume. Please note that Portainer requires persistent storage in order to maintain the database and configuration information it needs to function.

You can create a Docker volume using the command;

docker volume create [OPTIONS] [VOLUME-NAME]

For example, to create a volume called pt_data, you can use the command. Name can be anything of your preference.

docker volume create pt_data

You can confirm the volumes by listing them;

docker volume ls

Sample output;

DRIVER    VOLUME NAME
local     pt_data

The voume is created under the Docker host path, /var/lib/docker/volumes/. See the output from the command below;

docker volume inspect pt_data
[
    {
        "CreatedAt": "2022-06-09T17:56:05Z",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/pt_data/_data",
        "Name": "pt_data",
        "Options": {},
        "Scope": "local"
    }
] 

Install Portainer on Ubuntu 22.04

Next, download and install Portainer server Docker container on Ubuntu 22.04;

docker run -d -p 8000:8000 -p 9443:9443 --name portainer \
--restart=always -v /var/run/docker.sock:/var/run/docker.sock \
-v pt_data:/data portainer/portainer-ce:latest
  • Note that the Portainer Server listens on port TCP 9443 for the UI and API and on an optional port TCP 8000, which is only required if using Edge Compute features with Edge Agents.
  • The Portainer Agents listen on TCP port 9001

Demystifying the Docker command line options used above;

  • -d/--detach: Causes the container in background and print container ID
  • -p/--publish: Exposes/Publishes a container’s port(s) to the host.
    • 9443:9443: For example, Portainer server container port 9443 can be accessed on the main Docker host on port 9443.
  • --name: Assign a name to the container.
  • --restart: Restart policy to apply when a container exits (default “no”)
    • always means Always restart the container regardless of the exit status
    • it also causes the container to start on daemon startup, regardless of the current state of the container
  • -v/--volume: Bind mount a Docker container volume.
    • -v /var/run/docker.sock:/var/run/docker.sock: This causes the Portainer Server container process to communicate with the main host Docker process.
    • -v pt_data:/data: Mounts the Portainer Server container data, /data, to the host path /var/lib/docker/volumes/pt_data.
  • And then of course the Portainer image we are using, the Portainer CE latest container image, portainer/portainer-ce:latest.

Sample output from the command above;

Portainer server should now be running.

You can list running Docker container using the command;

docker ps

Sample output;

CONTAINER ID   IMAGE                           COMMAND        CREATED              STATUS          PORTS                                                                                            NAMES

You can confirm that actually, the Portainer server UI port is opened on the host as well.

ss -altnp | grep 9443
LISTEN 0      4096         0.0.0.0:9443      0.0.0.0:*    users:(("docker-proxy",pid=3760,fd=4))   
LISTEN 0      4096            [::]:9443         [::]:*    users:(("docker-proxy",pid=3767,fd=4))

Accessing Portainer Server Web Interface

Portainer server web services is exposed to the Docker host on port 9443/TCP.

In order to access Portainer server UI, then navigate to the browser and enter the address https://docker-domain-or-IP:9443
