搭建私有docker hub

安装

$ docker pull registry

$ docker images

docker镜像删除后会把所有的数据和文件都删除，所以要把主机的本地目录挂在到registry容器内部目录上，在删除registry后依旧能保证文件和数据不丢失。

$ mkdir -p ~/docker/data/registry

$ cd ~/docker/data/registry/

$ pwd
/Users/yshi3/docker/data/registry			# 数据文件夹

创建registry镜像容器，绑定5000端口

$ docker run -d -p 5000:5000 --restart=always -v /Users/yshi3/docker/data/registry:/var/lib/registry registry:latest
dcfaa1c3b1459c7e4c3c5d152aecf9c43863ede6b957e642e9633eb9bb430e31

$ docker ps
CONTAINER ID   IMAGE                                                         COMMAND                  CREATED          STATUS          PORTS                                                                                                                                  NAMES

$ netstat -ant | grep 5000 
tcp46      0      0  *.5000                 *.*                    LISTEN

为registry创建用户名密码

$ mkdir  /Users/yshi3/docker/data/registry/auth

$ docker run --entrypoint htpasswd registry:latest -Bbn felix felix  >> /Users/yshi3/docker/data/registry/auth/htpasswd
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "htpasswd": executable file not found in $PATH: unknown.

# 错误解决

好了现在5000端口就是我们的私有docker hub了

本地镜像上传到docker hub

  1. 查看本地有哪些镜像

    $ docker images
REPOSITORY                                                   TAG          IMAGE ID       CREATED        SIZE

  2. 我们安装一个jenkins作为测试对象

    $ docker run -d -p 80:8080 -p 50000:50000 -v jenkins:/var/jenkins_home -v /etc/localtime:/etc/localtime --name jenkins jenkins/jenkins

$ registry docker ps
CONTAINER ID   IMAGE                                 COMMAND                  CREATED          STATUS          PORTS                                                                                                                                  NAMES
1a52a898bea9   jenkins/jenkins                       "/sbin/tini -- /usr/…"   5 minutes ago    Up 5 minutes    0.0.0.0:50000->50000/tcp, :::50000->50000/tcp, 0.0.0.0:80->8080/tcp, :::80->8080/tcp                                                   jenkins
3eb912684830   registry                              "/entrypoint.sh /etc…"   26 minutes ago   Up 26 minutes   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp                                                                                              nifty_colden

  3. 基于jenkins创建customize jenkins

    jenkins                                                      customize    220f3c3059b7   32 seconds ago   445MB

  4. 选择jenkins镜像，加上tag

    命令: docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

    $ docker commit -m "cusotmize jenkins" -a "shyandsy" 1a52a898bea9 jenkins:customize
sha256:220f3c3059b7a9f3d0b14a42062a28ad42d02586c6860490917d0c3264867a0f

$ docker images
REPOSITORY                                                   TAG          IMAGE ID       CREATED          SIZE
jenkins                                                      customize    220f3c3059b7   32 seconds ago   445MB

registry                                                     latest       b2cb11db9d3d   2 months ago     26.2MB
mos-docker.arf.tesla.cn/tesla/app/mos-db-by-jeremy           20210329     47ed61e142a7   7 months ago     6.66GB


$ docker tag jenkins:customize 127.0.0.1:5000/customize_jenkins

 docker images
REPOSITORY                                                   TAG          IMAGE ID       CREATED        SIZE
127.0.0.1:5000/customize_jenkins                             latest       220f3c3059b7   5 hours ago    445MB

    可以看到生成 了docker image： 127.0.0.1:5000/customize_jenkins

  5. 上传到自己的docker hub

    $ docker push 127.0.0.1:5000/customize_jenkins
Using default tag: latest
The push refers to repository [127.0.0.1:5000/customize_jenkins]
