## 配置containerd ##

`vim /etc/containerd/config.toml`

[plugins]
      [plugins."io.containerd.grpc.v1.cri"]
        [plugins."io.containerd.grpc.v1.cri".containerd]
          default_runtime_name = "kata"
          [plugins."io.containerd.grpc.v1.cri".containerd.runtimes]
            [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.kata]
              runtime_type = "io.containerd.kata.v2"

## 测试 ##

> 需保证`vhost_vsock`内核模块已经加载

zxl@linux:~$ lsmod | grep vsock
    zxl@linux:~$ sudo modprobe vhost_vsock
    zxl@linux:~$ lsmod | grep vsock
    vhost_vsock            28672  0
    vmw_vsock_virtio_transport_common    40960  1 vhost_vsock
    vhost                  53248  1 vhost_vsock
    vsock                  49152  2 vmw_vsock_virtio_transport_common,vhost_vsock

eg1：  
![在这里插入图片描述][0fc4ee37b029415aaa7555082bbec25f.png]

sudo ctr run  --runtime "io.containerd.kata.v2" --rm -t docker.io/library/nginx:latest test  uname -r
    
    # output 注意与宿主机的内核版本的区别
    5.19.2

eg2：

$ image="docker.io/library/busybox:latest"
    $ sudo ctr image pull "$image"
    $ sudo ctr run --runtime "io.containerd.kata.v2" --rm -t "$image" test-kata uname -r
    # 5.19.2
