docker學習筆記（二）——本地私有倉庫Registry的搭建與驗證

Registry的部署

獲取registry鏡像

#docker pull registry:2.1.1

啓動registry容器

#docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:2.1.1
查看進程
# docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                    NAMES
ac291ed888fe        registry:2.1.1            "/bin/registry /et..."   27 minutes ago      Up 27 minutes       0.0.0.0:5000->5000/tcp   registry

驗證服務是否正常
#curl http://127.0.0.1:5000/v2/
{}

上傳鏡像

查看本地已有鏡像
# docker p_w_picpaths
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               v2                  570d531c994a        4 hours ago         107MB
nginx               latest              b8efb18f159b        3 weeks ago         107MB
centos              6.8                 0cd976dc0a98        11 months ago       195MB
registry            2.1.1               52bb991b482e        22 months ago       220MB

建立docker tag 鏡像
# docker tag nginx:v2 127.0.0.1:5000/nginx:v2
即用ningx:v2建立 127.0.0.1:5000/nginx:v2的鏡像

# docker p_w_picpaths
REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
127.0.0.1:5000/nginx   v2                  570d531c994a        4 hours ago         107MB
nginx                  v2                  570d531c994a        4 hours ago         107MB
nginx                  latest              b8efb18f159b        3 weeks ago         107MB
centos                 6.8                 0cd976dc0a98        11 months ago       195MB
registry               2.1.1               52bb991b482e        22 months ago       220MB

push鏡像到本地倉庫
# docker push 127.0.0.1:5000/nginx:v2
The push refers to a repository [127.0.0.1:5000/nginx]
04a8761254c7: Pushed 
af5bd3938f60: Pushed 
29f11c413898: Pushed 
eb78099fbf7f: Pushed 
v2: digest: sha256:9586184eb142f8c66decfd4fd7b3a2b54abfcb0f0a25541e69ba3725c61ba8b3 size: 8522

查看是否已經上傳

# curl http://192.168.12.109:5000/v2/_catalog
{"repositories":["nginx"]}
