containerd部署

---

1. 部署runc

下载压缩包https://github.com/opencontainers/runc/releases/runc.<ARCH>，安装到/usr/local/sbin/runc

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

2. 部署CNI-plugins

下载相应的版本https://github.com/containernetworking/plugins/releases/cni-plugins-<OS>-<ARCH>-<VERSION>.tgz，创建/opt/cni/bin，将压缩包中的二进制文件解压到/opt/cni/bin文件夹下

# mkdir -p /opt/cni/bin
# tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.1.1.tgz
./
./macvlan
./static
./vlan
./portmap
./host-local
./vrf
./bridge
./tuning
./firewall
./host-device
./sbr
./loopback
./dhcp
./ptp
./ipvlan
./bandwidth

3. 部署crictl

下载安装，根据系统下载tar包，将二进制文件解压到/usr/local/bin下

VERSION="v1.26.0"
wget https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/crictl-$VERSION-linux-amd64.tar.gz
sudo tar zxvf crictl-$VERSION-linux-amd64.tar.gz -C /usr/local/bin
rm -f crictl-$VERSION-linux-amd64.tar.gz

使用crictl命令生成crictl.yaml配置文件

# /etc/crictl.yaml

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

4. 部署containerd

根据系统下载相应的tar包，下载路径https://github.com/containerd/containerd/releases/containerd-<VERSION>-<OS>-<ARCH>.tar.gz，将想在的tar.gz包解压缩到/usr/local/bin下

tar Cxzvf /usr/local containerd-1.6.2-linux-amd64.tar.gz
bin/
bin/containerd-shim-runc-v2
bin/containerd-shim
bin/ctr
bin/containerd-shim-runc-v1
bin/containerd
bin/containerd-stress

创建配置文件。在/etc下创建containerd文件夹，使用containerd命令创建config文件

# containerd config default > /etc/containerd/config.toml

5.安装nerdctl

nerdctl是一个兼容 Docker 的 CLI，适用于 containerd。去github中下载相应的压缩包，然后解压缩到/usr/local/bin下

# 下载
wget https://github.com/containerd/nerdctl/releases/download/v1.1.0/nerdctl-1.1.0-linux-amd64.tar.gz

# 解压
tar Cxzvf /usr/local/bin nerdctl-1.1.0-linux-amd64.tar.gz

6.安装buildkit

BuildKit 是一个工具包，用于转换源代码以高效、富有表现力和可重复的方式构建工件。

# 下载
wget https://github.com/moby/buildkit/releases/download/v0.11.2/buildkit-v0.11.2.linux-amd64.tar.gz

# 解压
tar Cxzvf /usr/local/bin buildkit-v0.11.2.linux-amd64.tar.gz

配置systemd启动systemctl enable buildkit && systemctl start buildkit
