# Linux 安装 Docker
|
||
|
|
|
||
|
|
# centos下安装docker
|
||
|
|
> 其他系统参照如下文档
|
||
|
|
|
||
|
|
https://docs.docker.com/engine/install/centos/
|
||
|
|
## 1、移除以前docker相关包
|
||
|
|
``` shell
|
||
|
|
sudo yum remove docker \
|
||
|
|
docker-client \
|
||
|
|
docker-client-latest \
|
||
|
|
docker-common \
|
||
|
|
docker-latest \
|
||
|
|
docker-latest-logrotate \
|
||
|
|
docker-logrotate \
|
||
|
|
docker-engine
|
||
|
|
```
|
||
|
|
|
||
|
|
## 2、配置yum源
|
||
|
|
``` shell
|
||
|
|
sudo yum install -y yum-utils
|
||
|
|
sudo yum-config-manager \
|
||
|
|
--add-repo \
|
||
|
|
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
|
||
|
|
```
|
||
|
|
|
||
|
|
## 3、安装docker
|
||
|
|
``` shell
|
||
|
|
sudo yum install -y docker-ce docker-ce-cli containerd.io
|
||
|
|
|
||
|
|
|
||
|
|
#以下是在安装k8s的时候使用
|
||
|
|
yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6
|
||
|
|
```
|
||
|
|
|
||
|
|
## 4、启动
|
||
|
|
```
|
||
|
|
systemctl enable docker --now #--now 立即执行
|
||
|
|
```
|
||
|
|
|
||
|
|
## 5、配置加速
|
||
|
|
这里额外添加了docker的生产环境核心配置cgroup
|
||
|
|
``` json
|
||
|
|
sudo mkdir -p /etc/docker
|
||
|
|
|
||
|
|
sudo tee /etc/docker/daemon.json <<-'EOF'
|
||
|
|
{
|
||
|
|
"registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],
|
||
|
|
"exec-opts": ["native.cgroupdriver=systemd"],
|
||
|
|
"log-driver": "json-file",
|
||
|
|
"log-opts": {
|
||
|
|
"max-size": "100m"
|
||
|
|
},
|
||
|
|
"storage-driver": "overlay2"
|
||
|
|
}
|
||
|
|
EOF
|
||
|
|
|
||
|
|
sudo systemctl daemon-reload
|
||
|
|
|
||
|
|
sudo systemctl restart docker
|
||
|
|
```
