DOCKER 服务学习三

Docker 客户端和守护进程(C/S模式)

remote-api 链接
连接方式
* unix:///var/run/docker.sock
* tcp://host:port
* fd://socketfd

cli/APP -> Docker Client –Socket–> Docker Server

举例: nc -U /var/run/docker.sock
GET /info HTTP/1.1

 

Docker 守护进程的配置和操作

sudo status docker
sudo service docker start
sudo service docker restart
sudo service docker stop

docker 配置文件
/lib/systemd/system/docker.service
/etc/defalut/docker
DOCKER_OPTS=’–label name=docker_server_01 -H tcp:0.0.0.0:2375′
DOCKER_OPTS=’–label name=docker_server_01 tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock’
DOCKER_OPTS=’–label name=docker_server_01 -H 0.0.0.0:2375 -H unix:///var/run/docker.sock’

Docker 的远程访问
docker -H http://10.0.0.1:2375
使用环境变量 DOCKER_HOST
export DOCKER_HOST=”tcp://10.0.0.1:2375″
