Docker私有仓库安装及运用

1. 下载插件 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 2. 增加权限 sudo chmod a+x /usr/local/bin/delete_docker_registry_image 3. 设置环境变量 export REGISTRY_DATA_DIR=/opt/docker_registry/registry/docker/registry/v22.2 镜像删除测试

1. 查询私有仓库的所有镜像: curl http://10.9.21.13:30100/v2/_catalog 2. 查看私有仓库某个镜像的所有tag: curl http://10.9.21.13:30100/v2/dining-test/tags/list 3. 进入容器: docker exec -it synjones_docker_registry sh 4. 查看仓库大小: du -sch /var/lib/registry 5. 退出容器：exit 6. 删除指定镜像： 设置环境变量：export REGISTRY_DATA_DIR=/opt/docker_registry/registry/docker/registry/v2 删除命令：delete_docker_registry_image --image dining-test:release-v1.0.0 7. 进入容器: docker exec -it synjones_docker_registry sh 8. 查看仓库大小: du -sch /var/lib/registry 9. 退出容器：exit2.3 删除示例

查看所有仓库 curl http://10.9.21.13:30100/v2/_catalog 或通过浏览器打开的办法: http://10.9.21.13:30100/v2/_catalog 查看私有仓库某个镜像的所有tag curl http://10.9.21.13:30100/v2/python/tags/list 或通过浏览器打开的办法：http://10.9.21.13:30100/v2/python/tags/list4. 办理须要https访问的问题

vi /etc/docker/daemon.json { // 重定向到http，配置须要通过http要求的地址，加到末了，否则别忘却加 , (json构造) "insecure-registries": ["10.9.21.13:30100"], } 阐明：由于是通过本地安装的docker进行操作，以是须要修合法地docker的配置文件5. 重启docker

systemctl daemon-reload systemctl restart docker利用1. 查询私有仓库镜像

# 查询私有仓库的所有镜像curl http://10.9.21.13:30100/v2/_catalog# 查看私有仓库某个镜像的所有tagcurl http://10.9.21.13:30100/v2/dining-test/tags/list2. 上传

通过docker上传本地镜像到私有仓库python:3.8：指的是本地镜像docker tag python:3.8 10.9.21.13:30100/python:3.8docker push 10.9.21.13:30100/python:3.8 # 想要上传，必须先打标签3. 下载

下载私有仓库镜像 先删除本地python:3.8的镜像，再通过如下命令下载 docker pull 10.9.21.13:30100/python:3.8
