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
1 #拉取registry镜像 2 [root@localhost home]# docker pull registry 3 Using default tag: latest 4 latest: Pulling from library/registry 5 c87736221ed0: Pull complete 6 1cc8e0bb44df: Pull complete 7 54d33bcb37f5: Pull complete 8 e8afc091c171: Pull complete 9 b4541f6d3db6: Pull complete 10 Digest: sha256:8004747f1e8cd820a148fb7499d71a76d45ff66bac6a29129bfdbfdc0154d146 11 Status: Downloaded newer image for registry:latest 12 13 #查看镜像 14 [root@localhost home]# docker images 15 REPOSITORY TAG IMAGE ID CREATED SIZE 16 registry latest f32a97de94e1 6 months ago 25.8MB 17 18 #启动容器 19 [root@localhost home]# docker run -d -v /data/registry:/var/lib/registry -p 5000:5000 --restart=always --name qdockerhub registry:latest 20 67b0ac40561688b8bb874fa9674e44eb069cc6ee443127ba80b140ea51947af7 21 22 #测试/v2/_catalog接口 23 [root@localhost home]# curl http://127.0.0.1:5000/v2/_catalog 24 {"repositories":[]} 25 [root@localhost home]#

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
