返回目录
docker安装
安装依赖
yum install -y yum-utils device-mapper-persistent-data lvm2
添加软件源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
重建yum缓存
yum clean all
yum makecache
安装docker-ce
yum -y install docker-ce
注册docker服务
systemctl enable docker
启动服务
systemctl start docker
查询docker image
docker search mysql
测试内容，可跳过：
下载docker image
docker pull mysql
启动docker container
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v E:/Cache/DockerContainerData/mysql/mysql-docker/data:/var/lib/mysql -v backup:/data --privileged --name=mysql-docker --ip 10.0.75.1 mysql
查询启动的container
docker ps
进入docker内部
docker exec -it mysql-docker bash
链接mysql
mysql -uroot –p123456;
授权远程访问
刷新权限
flush privileges;
重新启动mysql服务
service mysql restart
退出mysql
quit;
关闭一个container
docker stop mysql-docker
启动一个container
docker start mysql-docker
查看一个container的网络配置
docker inspect mysql-container
测试内容，可跳过，结束
加速：https://xxxxxx.mirror.aliyuncs.com从阿里云获取
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [“https://xxxxxx.mirror.aliyuncs.com”]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
修改docker image存储位置至外挂nfs，nfs设置参考前文
停止docker
service docker stop
修改文件，记得创建data-root的文件夹：
vi /etc/docker/daemon.json
添加
“data-root”: “/root/Myself/204share/data/docker/200”
删除信息
vim /usr/lib/systemd/system/docker.service
从-H删除后面的内容
并添加如下内容
–graph /root/Myself/204share/data/docker/200
mkdir -p /root/Myself/204share/data/docker/200
#重新载入系统服务，必须执行！
systemctl daemon-reload
service docker start
查看一下docer的当前运行信息：
docker info | grep “Docker Root Dir”
docker register安装
我的docker register安装在204：nfs上
运行：
docker pull registry
docker run -d -p 5000:5000 --restart=always --name registry -v /share/data/docker/store:/tmp/registry docker.io/registry:latest
测试下载、上传
docker pull nginx
docker tag nginx:latest 192.168.50.204:5000/nginx:v1
docker push 192.168.50.204:5000/nginx:v1
curl -X GET http://192.168.50.204:5000/v2/_catalog可以看到上传了的镜像
vim /etc/docker/daemon.json
“insecure-registries”:[“192.168.50.204:5000”]
systemctl restart docker
删除私服上的镜像
curl -I -X GET http://192.168.50.204:5000/v2/nginx/manifests/v1
