Jack Wallen walks you through the process of manually installing the Containerd container runtime engine on Ubuntu Server 22.04.
Containerd is a container runtime engine created for simplicity and portability. This runtime is considered an industry standard and is available as a daemon for Linux and Windows and can manage the entire container lifecycle for image transfer and storage, container deployment and supervision, storage and network, and more.

I’m going to walk you through the process of installing Containerd on Ubuntu Server 22.04. This isn’t quite as simple as installing the Docker runtime engine, but it’s only just a matter of running a few commands. With the introduction out of the way, let’s get right to the installation.
How to install Containerd on Ubuntu Server
There are a few pieces to this puzzle, the first of which is the Containerd runtime itself. To begin with, download the Containerd runtime with the command:
Do check the Containerd Download page to ensure you’re downloading the latest release.
Unpack that file into /usr/local/ with the command:
sudo tar Cxzvf /usr/local containerd-1.6.8-linux-amd64.tar.gz
Next, we need the runc command line tool which is used to deploy containers with Containerd. Download this package with:
Install runc with:
sudo install -m 755 runc.amd64 /usr/local/sbin/runc
Now, we need the Container Network Interface, which is used to provide the necessary networking functionality. Download CNI with:
Create a new directory with:
sudo mkdir -p /opt/cni/bin
Unpack the CNI file into our new directory with:
sudo tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.1.1.tgz
How to configure Containerd
With everything installed, we can now configure Containerd. Create a new directory to house the Containerd configurations with:
sudo mkdir /etc/containerd
Create the configurations with:
containerd config default | sudo tee /etc/containerd/config.toml
Enable SystemdCgroup with the command:
sudo sed -i 's/SystemdCgroup \= false/SystemdCgroup \= true/g' /etc/containerd/config.toml
Download the required systemd file with:
sudo curl -L https://raw.githubusercontent.com/containerd/containerd/main/containerd.service -o /etc/systemd/system/containerd.service
Reload the systemd daemon with:
sudo systemctl daemon-reload
Finally, start and enable the Containerd service with:
sudo systemctl enable --now containerd
You can verify everything is running with the command:
sudo systemctl status containerd
You should see output similar to this:
containerd.service - containerd container runtime
Loaded: loaded (/etc/systemd/system/containerd.service; enabled; vendor pre>
Active: active (running) since Wed 2022-09-21 12:17:24 UTC; 6s ago
Process: 1475 ExecStartPre=/sbin/modprobe overlay (code=exited, status=0/SUC>
Main PID: 1478 (containerd)
Congratulations, you now have the Containerd container runtime engine ready to serve on Ubuntu Server 22.04. Next time up, we’ll pull down an image and deploy a container with this powerful system.
