7.Docker 配置registry私有仓库

server 执行以下命令，创建私有仓库

#修改交互协议
 vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://i70c3eqq.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.199.120:5000"]
}
#重启docker服务
systemctl restart docker

#下载镜像
docker pull hub.c.163.com/library/registry:latest
docker tag hub.c.163.com/library/registry:latest registry
#启动容器
docker run -d --name=registry -p 5000:5000 --restart=always -v /myreg:/var/lib/registry registry

client ： 192.168.199.121 执行推送镜像命令
注意:镜像名称严格安照 ip:端口/镜像名

#修改交互协议
vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://i70c3eqq.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.199.120:5000"]
}
#重启docker服务
systemctl restart docker

#查看构建的镜像
docker images

#执行推送命令（镜像严格按照registry格式命名）
docker push 192.168.199.120:5000/centos:v1 

获取本地仓库192.168.199.120中存储的镜像

curl http://192.168.199.120:5000/v2/_catalog
{"repositories":["centos_push"]} #有一个叫 centos_push 镜像

curl http://192.168.199.120:5000/v2/centos_push/tags/list #查看centos_push 拥有的版本信息
{"name":"centos_push","tags":["latest","v1","v2","v3"]}

添加本地仓库为默认下载镜像地址

vim /etc/sysconfig/docker
#添加一行：
ADD_REGISTRY='--add-registry 192.168.199.120:5000'
#重启docker服务
systemctl restart docker

本地仓库删除镜像 192.168.199.120:5000/centos:v1

curl https://raw.githubusercontent.com/burnettk/delete-docker-registry-image/master/delete_docker_registry_image.py|sudo tee /usr/local/bin/delete_docker_registry_image >/dev/null
chmod a+x /usr/local/bin/delete_docker_registry_image
#本地挂载点为myreg
export REGISTRY_DATA_DIR=/myreg/docker/registry/v2
/usr/local/bin/delete_docker_registry_image -i centos:v1
