Linux通过curl访问docker.sock/API执行docker操作

官方API doc: https://docs.docker.com/engine/api/v1.41/

官方API doc(with example): https://docs.docker.com/engine/api/sdk/examples/

不同版本的docker的api doc: https://docs.docker.com/engine/api/#api-version-matrix

通过curl socket完成镜像拉取操作

基本报文

POST /v1.41/images/create?fromImage=10.82.123.123%2Fpublic%2Fmaven&tag=3.3.9-public HTTP/1.1
Host: docker
User-Agent: Docker-Client/20.10.17 (linux)
Content-Length: 0
Content-Type: text/plain

命令实现

curl --unix-socket /var/run/docker.sock "http://localhost/v1.41/images/create?fromImage=10.82.123.123%2Fpublic%2Fmaven&tag=3.3.9-public" -X POST

如果拉取镜像需要认证可以加上http header
