Docker篇-源碼安裝docker-ce

1 引言

之前有同事問我怎麼安裝特定版本的docker，特此寫個筆記

2 安裝

• 下載安裝包到/opt/docker/work下

mkdir /opt/docker/work -pv

https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.17.0/crictl-v1.17.0-linux-amd64.tar.gz

https://github.com/opencontainers/runc/releases/download/v1.0.0-rc10/runc.amd64

https://github.com/containernetworking/plugins/releases/download/v0.8.5/cni-plugins-linux-amd64-v0.8.5.tgz

https://github.com/containerd/containerd/releases/download/v1.3.3/containerd-1.3.3.linux-amd64.tar.gz

• 解壓 cd /opt/docker/work

mkdir containerd
tar -xvf containerd-1.3.3.linux-amd64.tar.gz -C containerd
tar -xvf crictl-v1.17.0-linux-amd64.tar.gz

mkdir cni-plugins
sudo tar -xvf cni-plugins-linux-amd64-v0.8.5.tgz -C cni-plugins
sudo mv runc.amd64 runc

• 拷貝到自己的目錄下

mkdir -p /opt/docker/bin
export PATH=/opt/docker/bin:$PATH
cp {containerd/bin/* ,crictl ,cni-plugins/* ,runc } /opt/docker/bin/
chmod a+x /opt/docker/bin/*
##創建配置文件目錄
mkdir -p /etc/cni/net.d

• 創建配置文件

cat << EOF | sudo tee containerd-config.toml
version = 2
root = "${CONTAINERD_DIR}/root"
state = "${CONTAINERD_DIR}/state"

[plugins]
  [plugins."io.containerd.grpc.v1.cri"]
    sandbox_image = "registry.cn-beijing.aliyuncs.com/images_k8s/pause-amd64:3.1"
    [plugins."io.containerd.grpc.v1.cri".cni]
      bin_dir = "/opt/docker/bin"
      conf_dir = "/etc/cni/net.d"
  [plugins."io.containerd.runtime.v1.linux"]
    shim = "containerd-shim"
    runtime = "runc"
    runtime_root = ""
    no_shim = false
    shim_debug = false
EOF

mkdir -p /etc/containerd/ ${CONTAINERD_DIR}/{root,state}
cp containerd-config.toml /etc/containerd/config.toml

• 創建 containerd systemd unit 文件

cd /opt/docker/work

cat <<EOF | sudo tee containerd.service
[Unit]

[Service]

EOF

cp containerd.service /etc/systemd/system/
systemctl enable containerd && systemctl restart containerd
