拉取registry镜像
meiya@meiya:/etc/docker$ docker pull registry Using default tag: latest latest: Pulling from library/registry c87736221ed0: Pull complete 1cc8e0bb44df: Pull complete 54d33bcb37f5: Pull complete e8afc091c171: Pull complete b4541f6d3db6: Pull complete Digest: sha256:3b00e5438ebd8835bcfa7bf5246445a6b57b9a50473e89c02ecc8e575be3ebb5 Status: Downloaded newer image for registry:latest

docker 镜像删除后会把所有的数据和文件都删除，所以要把宿主机的本地目录挂载到registry容器内部的目录上，在删除registry容器后依旧能保证文件和数据不丢失
meiya@meiya:/etc/docker$ mkdir -p ~/docker/data/registry meiya@meiya:/etc/docker$ cd / bin/ cdrom/ etc/ lib/ lost+found/ mnt/ proc/ run/ snap/ sys/ usr/ boot/ dev/ home/ lib64/ media/ opt/ root/ sbin/ srv/ tmp/ var/ meiya@meiya:/etc/docker$ cd / bin/ cdrom/ etc/ lib/ lost+found/ mnt/ proc/ run/ snap/ sys/ usr/ boot/ dev/ home/ lib64/ media/ opt/ root/ sbin/ srv/ tmp/ var/ meiya@meiya:/etc/docker$ cd ~/docker/data/registry/ meiya@meiya:~/docker/data/registry$ pwd /home/meiya/docker/data/registry meiya@meiya:~/docker/data/registry$
创建registry镜像容器，绑定5000端口
meiya@meiya:~/docker/data/registry$ docker run -d -p 5000:5000 -v /home/meiya/docker/data/registry:/tmp/registry registry 0a922d940f7c9d7c4c3e4d81caaf3d5582e34fbb49e2824675b4c43b652e3240 meiya@meiya:~/docker/data/registry$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0a922d940f7c registry "/entrypoint.sh /etc…" 7 seconds ago Up 6 seconds 0.0.0.0:5000->5000/tcp nifty_ganguly meiya@meiya:~/docker/data/registry$ netstat -ntlp | grep 5000 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp6 0 0 :::5000 :::* LISTEN - meiya@meiya:~/docker/data/registry$ telnet 192.168.1.57 5000 Trying 192.168.1.57...

将本地的镜像加上tag ， 然后上传私服
meiya@meiya:~/docker/data/registry$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE tomcat latest 27600aa3d7f1 37 hours ago 463MB registry latest f32a97de94e1 2 months ago 25.8MB meiya@meiya:~/docker/data/registry$ docker tag tomcat 192.168.1.57:5000/tomcat meiya@meiya:~/docker/data/registry$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE 192.168.1.57:5000/tomcat latest 27600aa3d7f1 37 hours ago 463MB tomcat latest 27600aa3d7f1 37 hours ago 463MB registry latest f32a97de94e1 2 months ago 25.8MB meiya@meiya:~/docker/data/registry$ docker push 192.168.1.57:5000/tomcat The push refers to repository [192.168.1.57:5000/tomcat] Get https://192.168.1.57:5000/v2/: http: server gave HTTP response to HTTPS client meiya@meiya:~/docker/data/registry$
这里出了个问题 ，主要是因为docker新版本默认不支持https协议，开放https协议
Get https://192.168.1.57:5000/v2/: http: server gave HTTP response to HTTPS client
解决办法，修改docker的配置文件，
修改默认的配置文件
sudo vi /etc/default/docker
加入
DOCKER_OPTS="--registry-mirror=https://registry.docker-cn.com --insecure-registry=192.168.1.57:5000"
# Docker Upstart and SysVinit configuration file # # THIS FILE DOES NOT APPLY TO SYSTEMD # # Please see the documentation for "systemd drop-ins": # https://docs.docker.com/engine/admin/systemd/ # # Customize location of Docker binary (especially for development testing). #DOCKERD="/usr/local/bin/dockerd" # Use DOCKER_OPTS to modify the daemon startup options. #DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4" DOCKER_OPTS="--registry-mirror=https://registry.docker-cn.com --insecure-registry=192.168.1.57:5000" # If you need Docker to use an HTTP proxy, it can also be specified here. #export http_proxy="http://127.0.0.1:3128/" # This is also a handy place to tweak where Docker's temporary files go. #export DOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"
重启docker服务， 重启registry容器，重新push本地镜像

ps:
第二种办法是修改 /etc/docker/daemon.json 文件，重启docker服务， 重启registry容器，重新push本地镜像
meiya@meiya:~/docker/data/registry$ cat /etc/docker/daemon.json { "registry-mirrors": ["https://hdokp13m.mirror.aliyuncs.com"], "insecure-registries":["192.168.1.57:5000"], "registry-mirrors": ["https://registry.docker-cn.com"] }
查看私有仓库中的镜像
meiya@meiya:~/docker/data/registry$ curl get http://192.168.1.57:5000/v2/_catalog
curl: (6) Could not resolve host: get
{"repositories":["tomcat"]}
ps:
部分旧的docker版本使用的地址是 http://192.168.1.57:5000/v2/_search
