docker 推送仓库（含搭建、代理等）

1、配置代理，需要绕过认证问题

{
  "registry-mirrors": [
    "https://docker.registry.cyou",
    "https://docker-cf.registry.cyou",
    "https://dockercf.jsdelivr.fyi",
    "https://docker.jsdelivr.fyi",
    "https://dockertest.jsdelivr.fyi",
    "https://mirror.aliyuncs.com",
    "https://dockerproxy.com",
    "https://mirror.baidubce.com",
    "https://docker.m.daocloud.io",
    "https://docker.nju.edu.cn",
    "https://docker.mirrors.sjtug.sjtu.edu.cn",
    "https://docker.mirrors.ustc.edu.cn",
    "https://mirror.iscas.ac.cn",
    "https://docker.rainbond.cc",
    "https://do.nark.eu.org",
    "https://dc.j8.work",
    "https://dockerproxy.com",
    "https://gst6rzl9.mirror.aliyuncs.com",
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "http://mirrors.ustc.edu.cn/",
    "https://mirrors.tuna.tsinghua.edu.cn/",
    "http://mirrors.sohu.com/"
  ],
  "insecure-registries": [
    "registry.docker-cn.com",
    "docker.mirrors.ustc.edu.cn",
    "192.168.198.90:5000"
  ],
  "debug": true,
  "experimental": false,
  "proxies": {
    "http-proxy": "http://xxx:7890",
    "https-proxy": "http://xxx:7890"
  }
}

 `insecure-registries ` 是放开认证问题，允许 Docker 仓库使用非 HTTPS 协议，基本上如果哪个镜像拉去失败了都在这里加。

`registry-mirrors` 是镜像地址

`proxies` 是代理地址

2、搭建docker仓库

# 1. 拉取官方Registry镜像（v2版本）
docker pull registry:2

# 2. 启动私有仓库（数据持久化到/opt/registry-data，避免容器删除丢失）
docker run -d \
  -p 5000:5000 \
  --name local-registry \
  -v /opt/registry-data:/var/lib/registry \
  --restart=always \
  registry:2

3、编译推送

构建镜像

docker build -t 192.168.198.90:5000/gin-test:v1.0 -f go-demo.Dockerfile .

推送镜像

docker push 192.168.198.90:5000/gin-test:v1.0

验证镜像

curl http://192.168.198.90:5000/v2/_catalog | grep gin-test

curl http://192.168.198.90:5000/v2/gin-test/tags/list

成功的话，镜像如下：

[root@localhost k8s-deploy]#  docker push 192.168.198.90:5000/gin-test:v1.0
The push refers to repository [192.168.198.90:5000/gin-test]
