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
