Launch Docker containers on Linux.
Instructions for installing Docker can be found on the manufacturer's site. For Debian / Ubuntu, I did the installation as follows.
Docker Engine vs. Docker Desktop
For Windows and MAC, Docker is available as Docker Desktop. The base for Docker on Windows and MAC provides a Linux virtual machine that allows Docker containers to run. In contrast, Linux with Docker Engine can use its own kernel and run Docker containers without a VM. So for Linux, I would use Docker Engine and not Docker Desktop:
sudo apt-get install ca-certificates curl gnupg lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-pluginThe current version, see: https://docs.docker.com/engine/install/
Alternative: Ubuntu Server - Server Snaps
When setting up an Ubuntu server (ubuntu.com/download/server), Docker can be selected directly during installation:
The Docker Container Runtime including Docker-compose is installed.

Docker-compose
Docker-compose allows multiple Docker containers to be stored in a common docker-compose.yml file, allowing them to be started or upgraded together. Docker-compose can be added with the following commands:
sudo apt install docker-composeRun Docker for a specific user without root
To allow the logged in user to execute Docker commands without "root", the user can be authorized as follows:
me@l1:~$ sudo apt install acl
me@l1:~$ sudo setfacl -m user:$USER:rw /var/run/docker.sockInstructions for the following platforms
For the following platforms, there is a corresponding Docker installation guide on the vendor site:
- Docker Desktop for Linux
- Docker Desktop for Mac (macOS)
- Docker Desktop for Windows
- CentOS
- Debian
- Fedora
- Raspberry Pi OS
- RHEL
- SLES
- Ubuntu
- Binaries

In preparation for moving my websites, I was looking for a way to simply forward all traffic from the old server to the new one.
Docker Swarm allows nodes (hosts) to be grouped together into a common federation. This allows containers to be run in any number of instances on any number of nodes (hosts) in the network. In Docker Swarm, the basis for communication between hosts is an overlay network for services: Multi-host networking. As indicated in my article on moving web servers, I tested Docker Swarm as a possible option for a shared cross-host network and gathered some insights on this, which I briefly summarize her...
In my article "All Docker containers: Moving hosts, theory and practice", I already went a little bit into the topic of backup. If you followed the article, you know that I outsource the data of my Docker containers via bind mounts and back them up with rsync. The backup job is started via crontab. But first, I thought about what actually needs to be backed up when using Docker in a single-server setup.
