Ubuntu16.04Docker的CS模式

Remote API

docker除了使用命令让用户通过客户端与docker的守护进行通信,也提供了Remote API方式的通信接口

RESTful风格API

STDIN,STDOUT,STDERR

连接方式

使用socket方式进行连接,有下列三种方式

unix:///var/run/docker.sock
tcp://host:port
fd://socketfd

eggyer@ubuntu:/usr/local/dockerfile/df_test1$ docker version
Client:
 Version:   1.9.1
 API version: 1.21
 Go version:  go1.4.3
 Git commit:  a34a1d5
 Built:    Fri Nov 20 17:56:04 UTC 2015
 OS/Arch:   linux/amd64

Server:
 Version:   1.9.1
 API version: 1.21
 Go version:  go1.4.3
 Git commit:  a34a1d5
 Built:    Fri Nov 20 17:56:04 UTC 2015
 OS/Arch:   linux/amd64

如上所示可以看到server中APIversion(remote API的版本)

通过unix:///var/run/docker.sock访问

注意发送HTTP请求时输入完get信息后要连按两次回车

eggyer@ubuntu:/usr/local/dockerfile/df_test1$ nc -U /var/run/docker.sock
GET /info HTTP/1.1

HTTP/1.1 200 OK
Content-Type: application/json
Server: Docker/1.9.1 (linux)
Date: Sat, 26 Nov 2016 14:33:45 GMT
Content-Length: 1162
