How to start containerd as a service after yum install?

  • 772

I installed containerd on Amazon Linux 2 using the suggested commands:

sudo amazon-linux-extras enable docker
sudo yum install -y containerd

I added this in the EC2 user data script to run at instance launch time.

But, how am I supposed to start containerd (a container runtime - similar to docker) as a service? Since I installed through yum there doesn't seem to include a systemd service file. The binary is located on /usr/bin/containerd. Am I supposed to use echo in the boot script to generate a systemd service file or what is a good practice?

linux amazon-ec2 systemd containerd amazon-linux-2

    I ended up with adding these lines to the startup script:

    cat <<EOF | sudo tee /etc/systemd/system/containerd.service
[Unit]
Description=containerd
Documentation=https://containerd.io

[Service]
Type=notify
ExecStart=/usr/bin/containerd

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl enable containerd
sudo systemctl start containerd

    Looks like the containerd service was started:

    $ sudo ctr version
