How to Install Docker & Portainer on Your DigitalBerg Server

If you’re a DigitalBerg client looking to get your hosting environment ready for containerised applications, this guide walks you through installing Docker and Portainer on your Linux server (VPS or dedicated) quickly and reliably.

Step 1: Prepare Your Server

1. Log in to your server via SSH as the root user or a sudo‑enabled user.
2. Update your package lists and upgrade existing packages:

sudo apt update && sudo apt upgrade -y

3. If you’re using CentOS, AlmaLinux or Rocky Linux, run:

sudo dnf update -y

Make sure your server is registered under your DigitalBerg account and located in the region closest to your users to reduce latency.

Step 2: Install Docker

Run the following commands to install Docker on your server:

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install -y docker-ce

On CentOS/AlmaLinux/Rocky:

sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf install -y docker-ce docker-ce-cli containerd.io

Start and enable Docker:

sudo systemctl start docker
sudo systemctl enable docker

Step 3: Verify Docker Installation

Check Docker is running:

sudo docker run hello-world

You should see a message confirming Docker is installed correctly.

Step 4: Install Portainer

Portainer is a powerful lightweight management UI for Docker environments – ideal for container deployment at scale.

sudo docker volume create portainer_data
sudo docker run -d -p 9443:9443 --name portainer \
  --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce:latest

Access Portainer in your browser at https://<your-server-ip>:9443, set up an admin user and connect to the local Docker environment.

Step 5: Secure & Configure Your Environment

• Use firewalls or DigitalBerg’s control panel to restrict port 9443 access.
• Set up SSL/TLS certificates (free Let’s Encrypt recommended).
• Configure automated backups for your containers and Portainer configuration.
