【课件】配置containerd以使用kata containers作为runtime运行时

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：

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
