安装容器运行时

我们要先安装containerd，然后安装k8s，接着部署kubeedge、edgemesh以及sedna，跑一个官方示例的联合推理的应用案例。

实验环境：Debian GNU/Linux 12 (bookworm) x86_64，提前配置好了代理和apt镜像源，配置好代理方便从github上下载文件。
一点可能有用的建议：在进行分区时尽量将/var分区分配空间多一点（至少20G），/var是存放镜像和日志的地方。

安装containerd

官方安装文档：https://github.com/containerd/containerd/blob/main/docs/getting-started.md

安装containerd

1.下载containerd并安装到指定路径

wget -c <https://github.com/containerd/containerd/releases/download/v1.7.18/containerd-1.7.18-linux-amd64.tar.gz>

sudo tar Cxzvf /usr/local/bin/ containerd-1.7.18-linux-amd64.tar.gz

2.通过systemd启动containerd

wget -c <https://raw.githubusercontent.com/containerd/containerd/main/containerd.service>

sudo mkdir -p /usr/local/lib/systemd/system/

sudo cp containerd.service /usr/local/lib/systemd/system/

sudo chmod 755 /usr/local/lib/systemd/system/containerd.service

sudo systemctl daemon-reload

sudo systemctl enable --now containerd

3.配置containerd
获取默认配置内容

sudo mkdir -p /etc/containerd/

containerd config default | sudo tee /etc/containerd/config.toml

（1）修改config.toml中的sandbox_image（可选），systemd_cgroup，SystemdCgroup等属性：

# 将 sandbox_image = "registry.k8s.io/pause:3.6" 调整为
sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.9"

# 将 [plugins."io.containerd.grpc.v1.cri"] 下的 systemd_cgroup = false 注释掉
# systemd_cgroup = false

# 将 [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options] 下的 SystemdCgroup = false 调整为 true
SystemdCgroup = true

这里sandbox_image版本变成3.8是根据Kubernetes的版本来的（如果不是安装Kubernetes，可以不用修改）：

sudo kubeadm config images list --kubernetes-version v1.28.10
registry.k8s.io/kube-apiserver:v1.28.10
registry.k8s.io/kube-controller-manager:v1.28.10
registry.k8s.io/kube-scheduler:v1.28.10
registry.k8s.io/kube-proxy:v1.28.10
registry.k8s.io/pause:3.9
registry.k8s.io/etcd:3.5.12-0
registry.k8s.io/coredns/coredns:v1.10.1

（2）另外，如果从本地私有仓库拉取镜像，可能会遇到如下错误：Unable to pull image from insecure registry, http: server gave HTTP response to HTTPS client，为此我们需要对这个私有仓库（比如这里的 http://192.168.10.127:5000）进行安全设置：（这个笔者没有遇到这个问题，但考虑到可能有读者会遇到，还是从参考文章中复制了下来）

# 在 [plugins."io.containerd.grpc.v1.cri".registry] 下对 mirrors 和 mirrors 做如下配置
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors."192.168.10.127:5000"]
    endpoint = ["<https://192.168.10.127:5000>", "<http://192.168.10.127:5000>"]
[plugins."io.containerd.grpc.v1.cri".registry.configs]
  [plugins."io.containerd.grpc.v1.cri".registry.configs."192.168.10.127:5000".tls]     insecure_skip_verify = true

注意空格。
（3）个人建议添加国内镜像源方便镜像拉取。
阿里云镜像加速：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
华为云镜像加速：容器->容器镜像服务SWR->镜像资源->镜像中心->镜像加速器

      [plugins."io.containerd.grpc.v1.cri".registry.mirrors] #主要在这下面配置镜像加速服务
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
          endpoint=["https://****.mirror.aliyuncs.com","https://****.mirror.swr.myhuaweicloud.com"]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."registry.k8s.io"]
          endpoint=["https://****.mirror.aliyuncs.com","https://****.mirror.swr.myhuaweicloud.com"]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."192.168.10.127:5000"]
          endpoint = ["<https://192.168.10.127:5000>", "<http://192.168.10.127:5000>"]

重启containerd

sudo systemctl restart containerd

此外，还建议为containerd配置代理（需要事先已经配置好电脑代理）：

vim /lib/systemd/system/containerd.service

增加以下内容（根据自己的代理进行调整，笔者使用的是clash）：

Environment="HTTP_PROXY=http://127.0.0.1:7890"
Environment="HTTPS_PROXY=http://127.0.0.1:7890"
Environment="NO_PROXY =10.96.0.0/16,127.0.0.1,192.168.0.0/16,localhost"

安装runc

wget -c <https://github.com/opencontainers/runc/releases/download/v1.1.12/runc.amd64>

sudo install -m 755 runc.amd64 /usr/local/sbin/runc

我在操作的过程中发现还需要把/usr/local/sbin/加入到环境变量中，这个请自行搜索方法。

安装CNI plugins

sudo mkdir -p /opt/cni/bin

sudo tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.4.1.tgz

安装客户端

因为是配合k8s使用，所以选择安装crictl。

VERSION="v1.30.0"

wget <https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/crictl-$VERSION-linux-amd64.tar.gz>

sudo tar zxvf crictl-$VERSION-linux-amd64.tar.gz -C /usr/local/bin

配置：

cat << EOF | sudo tee /etc/crictl.yaml runtime-endpoint: unix:///run/containerd/containerd.sock image-endpoint: unix:///run/containerd/containerd.sock timeout: 2 debug: true pull-image-on-create: false EOF
