Ubuntu16.04Docker的CS模式

Remote API

docker除了使用命令讓用戶通過客戶端與docker的守護進行通信,也提供了Remote API方式的通信接口

RESTful風(fēng)格API

STDIN,STDOUT,STDERR

連接方式

使用socket方式進行連接,有下列三種方式

unix:///var/run/docker.sock

eggyer@ubuntu:/usr/local/dockerfile/df_test1$ docker versionClient: 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/amd64Server: 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)

通過unix:///var/run/docker.sock訪問

注意發(fā)送HTTP請求時輸入完get信息后要連按兩次回車
