安装 containerd

" class="reference-link">二进制部署

下载二进制:

  1. wget -q --show-progress --https-only --timestamping \
  2.   https://github.com/opencontainers/runc/releases/download/v1.0.0-rc8/runc.amd64 \
  3.   https://github.com/containerd/containerd/releases/download/v1.3.0/containerd-1.3.0.linux-amd64.tar.gz \
  4.   https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.16.1/crictl-v1.16.1-linux-amd64.tar.gz
  6. sudo mv runc.amd64 runc

安装二进制:

  1. tar -xvf crictl-v1.16.1-linux-amd64.tar.gz
  2. chmod +x crictl runc
  3. sudo cp crictl runc /usr/local/bin/
  5. mkdir containerd
  6. tar -xvf containerd-1.3.0.linux-amd64.tar.gz -C containerd
  7. sudo cp containerd/bin/* /bin/

创建 containerd 启动配置 config.toml:

  1. sudo mkdir -p /etc/containerd/
  2. cat << EOF | sudo tee /etc/containerd/config.toml
  3. [plugins]
  4.   [plugins.cri.containerd]
  5.     snapshotter = "overlayfs"
  6.     [plugins.cri.containerd.default_runtime]
  7.       runtime_type = "io.containerd.runtime.v1.linux"
  8.       runtime_engine = "/usr/local/bin/runc"
  9.       runtime_root = ""
  10. EOF

创建 systemd 配置 containerd.service:

  1. cat <<EOF | sudo tee /etc/systemd/system/containerd.service
  2. [Unit]
  3. Description=containerd container runtime
  4. Documentation=https://containerd.io
  5. After=network.target
  7. [Service]
  8. ExecStartPre=/sbin/modprobe overlay
  9. ExecStart=/bin/containerd
  10. Restart=always
  11. RestartSec=5
  12. Delegate=yes
  13. KillMode=process
  14. OOMScoreAdjust=-999
  15. LimitNOFILE=1048576
  16. LimitNPROC=infinity
  17. LimitCORE=infinity
  19. [Install]
  20. WantedBy=multi-user.target
  21. EOF

启动:

  1. sudo systemctl daemon-reload
  2. sudo systemctl enable containerd
  3. sudo systemctl start containerd

配置 crictl (方便后面使用 crictl 管理与调试 containerd 的容器与镜像):

  1. crictl config runtime-endpoint unix:///var/run/containerd/containerd.sock
