How to Install Portainer Docker UI Web Interface on Debian 11

Portainer is a lightweight, free, open-source Docker management UI that allows you to manage your Docker container from a web browser. It provides a simple and user-friendly web interface to build and manage containers, images, networks, volumes, registries, services, and nodes. Portainer is a very useful tool for users who don’t know the Linux command line.

In this post, we will show you how to install Portainer Docker UI on Debian 11.

Prerequisites

• A server running Debian 11 on the Atlantic.Net Cloud Platform
• A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Debian 11 as the operating system with at least 4GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your server, run the following command to update your base system with the latest available packages.

apt-get update -y

Step 2 – Install Docker CE

Before installing Portainer, Docker CE must be installed on your server. You can install Docker CE by following the below steps:

First, install the required dependencies using the following command:

apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common

Next, add the Docker CE repository with the following command:

curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

Next, update the repository and install Docker CE with the following command:

apt-get update -y
apt-get install docker-ce docker-ce-cli containerd.io -y

Once Docker is installed, verify the Docker installation using the following command:

docker version

You should see the following output:

 docker-init:
  Version:          0.19.0
  GitCommit:        de40ad0

Step 3 – Install Docker Compose

You will also need to install Docker Compose to your system. First, download the latest version of Docker Compose binary using the following command:

wget https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64

Next, copy the downloaded binary to the system path:

cp docker-compose-linux-x86_64 /usr/local/bin/docker-compose

Next, set executable permissions to the Docker Compose binary:

chmod +x /usr/local/bin/docker-compose

Next, verify the Docker Compose installation using the following command:

docker-compose --version

You should see the following output:

Docker Compose version v2.2.2

Step 4 – Install Portainer UI

First, create a volume to store Portainer data using the following command:

docker volume create portainer_data

Next, run the following command to download the Portainer image from the Docker Hub registry, create a container, and expose the container on port 9000:

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

You should see the following output:

You can verify the running container using the following command:

docker ps

You should see the following output:

CONTAINER ID   IMAGE                 COMMAND        CREATED          STATUS          PORTS                                                                                  NAMES

Step 5 – Access Portainer UI

Now, open your web browser and access the Portainer UI using the URL http://your-server-ip:9000. You should see the following page:

Set your admin user and password and click on the Create user button. You will be asked to select the Docker environment that you want to manage:
