1-2 部署和加速
最后更新于:2022-04-02 07:36:51
#### Docker部署
清理旧的Docker
```
yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine -y
```
安装依赖
```
yum install -y yum-utils device-mapper-persistent-data lvm2
```
配置阿里云Docker源
```
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
```
查看源中的版本
```
#默认Docker版本1.13比较老
yum list docker-ce.x86_64 --showduplicates | sort -r
```
安装Docker
```
yum -y install docker-ce-19.03.5-3.el7
```
设置开机启动并启动服务
```
systemctl enable docker
systemctl start docker
```
镜像加速,修改源,并修改docker的驱动方式,为k8s管理做准备
##### 感谢DAOCloud([https://www.daocloud.io/mirror](https://www.daocloud.io/mirror))
```
cat > /etc/docker/daemon.json << EOF
{
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"]}
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
```
如果要更改docker的数据目录
/etc/docker/daemon.json增加如下内容"graph": "/docker/data/path",
如果加速地址有变,请到官网进行更新
```
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
```
备注:启动服务会失败,因为配置文件多了逗号
将/etc/docker/daemon.json最后的逗号去掉
测试拉取和运行
```
docker pull library/hello-world
docker run hello-world
```
#### 设置网络
设置后,Docker容器可以出外网
```
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
sysctl -p
```
##### 想拉取Docker Hub,先要注册,或者直接从Daocloud拉取
```
docker pull daocloud.io/centos:7
或
docker login
docker pull centos:7
```
