docker私有仓库registry的使用
- registry的安装
关于docker registry的安装，可以说简单的不能再简单了，docker run一个容器就好了，也就是一条命令的事
docker run -d -p 5000:5000 --restart=always --name registry -v /opt/myregistry:/var/lib/registry registry
- 上传镜像
上次镜像其实就两步，给镜像打tag和push上传
- 打tag
格式：docker tag 源镜像名字:版本 私有仓库地址/镜像名字:版本
例如：
docker tag centos:6.10 10.0.0.11:5000/centos:6.10
- push上传
docker push 10.0.0.11:5000/centos:6.10
默认上传肯定报错！
The push refers to a repository [10.0.0.11:5000/centos:6.10]
Get https://10.0.0.11:5000/v1/_ping: http: server gave HTTP response to HTTPS client
解决办法：
把自己的私有镜像仓库加到信任的仓库列表中。
vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"],
"insecure-registries": ["10.0.0.11:5000"]
}
systemctl restart docker
然后重新push
- 下载镜像
下载镜像就一条命令docker pull
例如：
docker pull 10.0.0.11:5000/centos:6.10
默认下载肯定报错！
Trying to pull repository 10.0.0.11:5000/centos ...
Get https://10.0.0.11:5000/v1/_ping: http: server gave HTTP response to HTTPS client
解决办法同上传
- 查看镜像列表
使用浏览器访问：
http://10.0.0.11:5000/v2/_catalog
- 查看镜像的版本
下面我已nginx为例
http://10.0.0.11:5000/v2/nginx/tags/list
- 删除镜像
1）进入docker registry的容器中
docker exec -it registry /bin/sh
- 删除repo
rm -fr /var/lib/registry/docker/registry/v2/repositories/nginx
- 清楚掉blob
registry garbage-collect /etc/docker/registry/config.yml
- 带认证的registry
yum install httpd-tools -y
mkdir /opt/registry-var/auth/ -p
htpasswd -Bbn oldboy 123456 >> /opt/registry-var/auth/htpasswd
docker run -d -p 5000:5000 -v /opt/registry-var/auth/:/auth/ -v /opt/myregistry:/var/lib/registry -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd registry
提示：上传下载镜像都需要登陆哦
docker login 10.0.0.11:5000
oldboy
123456
docker logout 10.0.0.11:5000登出
