安裝容器執行時

Shemol
流程记录云原生

我們要先安裝 containerd，然後安裝 k8s，接著部署 kubeedge、edgemesh 以及 sedna，跑一個官方示例的聯合推理應用案例。

實驗環境：Debian GNU/Linux 12 (bookworm) x86_64，提前配置好了代理和 apt 鏡像源，配置好代理方便從 github 上下載檔案。
一點可能有用的建議：在進行分割時盡量將 /var 分割區分配空間多一點（至少 20G），/var 是存放鏡像和日誌的地方。

安裝 containerd

官方安裝文件：https://github.com/containerd/containerd/blob/main/docs/getting-started.md

安裝 containerd

1.下載 containerd 並安裝到指定路徑

shell
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.透過 systemd 啟動 containerd

shell
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

取得預設配置內容

shell
sudo mkdir -p /etc/containerd/

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

（1）修改 config.toml 中的 sandbox_image（可選），systemd_cgroup，SystemdCgroup 等屬性：

toml
# 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

這裡 sandbox_image 版本變成 3.8 是根據 Kubernetes 的版本來的（如果不是安裝 Kubernetes，可以不用修改）：

shell
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，如果從本地私有倉庫拉取鏡像，可能會遇到如下錯誤：Unable to pull image from insecure registry, http: server gave HTTP response to HTTPS client，為此我們需要對這個私有倉庫（比如這裡的 http://192.168.10.127:5000）進行安全設定：（這個筆者沒有遇到這個問題，但考慮到可能有讀者會遇到，還是從參考文章中複製了下來）

toml
# 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）個人建議新增國內鏡像源方便鏡像拉取。

阿里雲鏡像加速：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

華為雲鏡像加速：容器->容器鏡像服務 SWR->鏡像資源->鏡像中心->鏡像加速器

toml
[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>"]

重啟 containerd

shell
sudo systemctl restart containerd

此外，還建議為 containerd 配置代理（需要事先已經配置好電腦代理）：

shell
vim /lib/systemd/system/containerd.service

增加以下內容（根據自己的代理進行調整，筆者使用的是 clash）：

plain text
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"

安裝 runc

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

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

我在操作的過程中發現還需要把 /usr/local/sbin/ 加入到環境變數中，這個請自行搜尋方法。

安裝 CNI plugins

shell
sudo mkdir -p /opt/cni/bin

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

安裝客戶端

因為是配合 k8s 使用，所以選擇安裝 crictl。

shell
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：

shell
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
