containerd is an industry-standard container runtime with an emphasis on simplicity, robustness, and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.

• Run with an interactive shell

  You can also start the container with an interactive shell to use containerd.

  docker run -it --rm openeuler/containerd:{Tag} bash
  

• Create a simple CNI configuration file

  Create a basic CNI config file(e.g., empty.conf) inside /etc/cni/net.d/ to avoid network plugin errors when starting containerd:

  mkdir -p /etc/cni/net.d/
  
  # vi /etc/cni/net.d/empty.conf
  {
    "cniVersion": "0.4.0",
    "name": "empty-net",
    "type": "bridge",
    "bridge": "cni0",
    "isGateway": true,
    "ipMasq": true,
    "ipam": {
      "type": "host-local",
      "subnet": "10.88.0.0/16",
      "routes": [
        { "dst": "0.0.0.0/0" }
      ]
    }
  }
  

• Create the containerd configuration directory

  Make sure the containerd config directory exist:

  mkdir -p /etc/containerd
  

• Generate the default containerd configuration file

  Generate the default configuration and save it to /etc/containerd/config.toml:

  ./containerd config default > /etc/containerd/config.toml
  

• Start containerd with the custom configuration

  Start the containerd daemon using the created config file in the background:

  ./containerd --config /etc/containerd/config.toml &
