有时候会有一些奇怪的镜像操作需要用到curl等工具去实现，遂有了本篇记录
这里主要记录集中与registry API交互过程中，auth -> get manifest info部分
针对 hub.docker.com 实例
" 一个 docker pull 指令会拉两部分，一部分是 manifest，一部分是 layer，前者指定了一个 image 相关的信息和 layer 的信息（一个 JSON 文件），后者就是一些大文件（layer）"
会用到的关联域名:
Location of Docker index: https://index.docker.io/
Location of the remote repository: https://registry-1.docker.io
实现:
假设需要拉取的镜像为alpine:3.17.0_rc1 即:
➤ docker pull alpine:3.17.0_rc1
那么在curl中的实现即为(是的，他有个library!):
➤ curl https://registry-1.docker.io/v2/library/alpine/manifests/3.17.0_rc1
这时候直接请求是会401的，要根据返回的www-authenticate header去进行认证
* Mark bundle as not supporting multiuse
< HTTP/1.1 401 Unauthorized
< content-type: application/json
< docker-distribution-api-version: registry/2.0
< www-authenticate: Bearer realm="https://auth.docker.io/token",service="registry.docker.io",scope="repository:library/alpine:pull"
< date: Sun, 20 Nov 2022 09:08:33 GMT
< content-length: 157
< strict-transport-security: max-age=31536000
< docker-ratelimit-source: 8.210.192.22

{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"repository","Class":"","Name":"library/alpine","Action":"pull"}]}]}
* Connection #1 to host registry-1.docker.io left intact
根据回显进行认证(匿名认证):
注意这里的service也是需要一一对应的，scope value可以不进行URL编码
➤ curl "https://auth.docker.io/token?scope=repository%3Alibrary%2Falpine%3Apull&service=registry.docker.io"

ps: 对于不存在的tag, hub.docker.com返回的是(http code: 404)
{"errors":[{"code":"MANIFEST_UNKNOWN","message":"manifest unknown","detail":"unknown tag=3.17.0_rc2"}]}
题外话: 手动认证请求registry的 /_catalog接口的实例
先匿名请求接口，遇到401

获取token:
注意这里的service也是需要一一对应的，scope value可以不进行URL编码
# curl "http://10.10.217.241/registry/token?service=BUILDIN-REGISTRY&scope=registry:catalog:*" -u admin:password-password
{
"token":"xxxx-token-x"
}
带上token，成功请求:
# curl 10.10.217.241/v2/_catalog -H "Authorization: Bearer xxxx-token-x"
{"repositories":[xxxxxxxxxxxxxx]}
