【linux】【docker】docker私服安装

前言

系统环境：Centos7、jdk1.8

docker私服：可以把项目通过dockerfile文件build成docker镜像，供其他环境拉取。部署在本地，私有化。

安装

dockerHUB私服

1. 搭建registry

 #拉取registry镜像

4.删除私服镜像

 # 查看当前docker私服中的镜像
 [root@localhost ~]# curl http://127.0.0.1:5000/v2/_catalog
 {"repositories":["mingbytesiteweb"]}

 # 查看docker私服容器，重点是 CONTAINER ID
 [root@localhost ~]# docker ps
 CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

 # 删除docker私服中的“mingbytesiteweb”镜像
 # 其中67b0ac405616 为docker私服容器id
 [root@localhost ~]# docker exec 67b0ac405616 rm -rf /var/lib/registry/docker/registry/v2/repositories/mingbytesiteweb

 # 清除掉blob
 # 67b0为docker私服容器id
 [root@localhost ~]# docker exec 67b0 bin/registry garbage-collect /etc/docker/registry/config.yml

错误集合

a. 运行错误1

错误提示: [root@izj6c0zsm04q86s2tu4e12z /]# docker run -it docker.io/ubuntu:latest /bin/bash
/usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:235: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccounting, or unknown property.\"".

解决办法: yum update

b. 私有仓库push错误(改配置后一定要重启docker)

• docker私有仓库的5000端口是否在防火墙中打开

• daemon.json文件中提交镜像的地址是否修改为私有docker仓库的地址

• 添加镜像仓库地址insecure-registries参数，内容修改如下：

vim /etc/docker/daemon.json
{
    "registry-mirrors":["https://registry.docker-cn.com"],
     "insecure-registries":["47.240.32.247:5000"]
}       

[root@localhost bin]# systemctl daemon-reload
[root@localhost bin]# systemctl restart docker
