Install Portainer on Ubuntu 20.04 with Docker

1. Keep server updated

Always keep your server up-to-date for security purpose.

# apt-get update -y

2. Install Docker

Install the required dependencies for Docker:

# apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y

Add the Docker CPG Key

# curl -fsSL https://download.docker.com/linux/ubuntu/gpg sudo apt-key add -

Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

# sudo apt-key fingerprint 0EBFCD88

Output:

pub rsa4096 2017-02-22 [SCEA]
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88
uid [ unknown] Docker Release (CE deb) <[email protected]>
sub rsa4096 2017-02-22 [S]

Add the Docker Repository

# add-apt-repository 'deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable'

The following command will download Docker and install it:

# apt-get update -y

# apt-get install docker-ce -y

Start and enable Docker service

# systemctl start docker && systemctl enable docker

3. Create a container

We’ll show you two ways to deploy the container.

1. If you want to use domain name to access Portainer, use following command to deploy the container:

# docker run --restart always -d --name=portainer -v /var/run/docker.sock:/var/run/docker.sock -v /vol/portainer/data:/data -e VIRTUAL_HOST=port.example.com -e VIRTUAL_PORT=9000 portainer/portainer-ce -H unix:///var/run/docker.sock

  • -v /var/run/docker.sock:/var/run/docker.sock means mounting /var/run/docker.sock to the container so portainer can control the Docker.
  • -v /vol/portainer/data:/data means storing data of portainer on directory /vol/portainer/data.
  • port.example.com is your domain to access the portainer.

2. If you want to access Portainer using server IP, use following command to deploy the container:

Install

# docker volume create portainer_data

# docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

4. Configure Reverse Proxy for Portainer (Optional if you will use domain name)

Caddyfile is a reverse proxy server. It is necessary to secure the connection to prevent network hijacking. Caddyfile can obtains and automatically maintains SSL certificate.

Create a Caddyfile. Caddyfile is a document containing configs for your sites:

Install portainer ubuntu 20.04Install portainer ubuntu windows

# mkdir -p /vol/caddy/configs
# vi /vol/caddy/configs/Caddyfile

Add following content:

port.example.com {
tls [email protected]
reverse_proxy portainer:8000
}

Replace: port.example.com with your domain name and [email protected] with your actual email id.

Save and exit.

Finally, create a Caddy container using following command:

# docker run --restart always -d -p 80:80 -p 443:443 -v '/vol/caddy/data:/data/caddy' -v '/vol/caddy/configs:/etc/caddy' --link portainer --name caddy caddy

  • -p 80:80 -p 443:443 means publish its 80 and 443 port to your host so you can access it with those ports.
  • -v '/vol/caddy/data:/data/caddy' means mount caddy working directory to your host to persist data such as certificates.
  • -v '/vol/caddy/configs:/etc/caddy' means mount caddy configuration directory to your host to persist configurations.
  • --link portainer means link container caddy with portainer so they can access with each other.
