Docker之registry安装部署

Docker之registry安装部署

我说了您可能就不会继续看registry了，但是我还是要说，这个东东真不好用，不如harbor（强烈推荐）。

1、安装docker

……此处省略……

2、拉取registry镜像

[root@registry ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
6a428f9f83b0: Pull complete 
90cad49de35d: Pull complete 
b215d0b40846: Pull complete 
429305b6c15c: Pull complete 
6f7e10a4e907: Pull complete 
Digest: sha256:265d4a5ed8bf0df27d1107edb00b70e658ee9aa5acb3f37336c5a17db634481e
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest
[root@registry ~]# 

3、创建授权使用目录

[root@registry ~]# mkdir -pv  /root/auth
mkdir: 已创建目录 "/root/auth"

4、创建授权文件

创建授权有两张方式（设置用户、密码）：
①、通过docker run --entrypoint htpasswd ……我用此命令创建有大量的报错
②、通过linux自带的htpasswd（httpd服务）创建

docker run --entrypoint htpasswd registry:latest -Bbn user91 password91 > /root/auth/htpasswd  #通过docker容器中htpasswd创建文件
htpasswd -bc htpasswd zqj zqj >> /root/auth/htpasswd #通过htpasswd命令生成文件

注：本文档采用本机htpasswd直接生成。

5、regisry启动

docker  run -d -p 5000:5000 --restart=always --name myRegistry01 -v /root/auth/htpasswd:/root/auth/htpasswd -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e "REGISTRY_AUTH_HTPASSWD_PATH=/root/auth/htpasswd" registry

6、验证registry与上传镜像

此处需要注意的是，Registry默认登录是https服务验证，如果需要通过http登录则需要在daemon.json中增加如下配置：
vim /etc/docker/daemon.json

{ “insecure-registries”:[“192.168.3.192:5000”]}

[root@registry ~]# docker login 192.168.3.192:5000
Username: zqj
Password:

7、拉取镜像

[root@registry ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
