docker開啓遠程訪問
系統使用centos7
一、打開docker端口
/usr/lib/systemd/system/docker.service
中
ExecStart=/usr/bin/dockerd-current \
#增加-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock 重啓docker
ExecStart=/usr/bin/dockerd-current -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock \
之後重啓docker讓配置生效。
即可通過http方式和docker -H方式訪問docker
二、命令測試
134上運行的容器
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4f191cbd3c26 redis "docker-entrypoint..." 6 months ago Up 9 hours 0.0.0.0:6379->6379/tcp some-redis
6de8887c05fa mysql "docker-entrypoint..." 6 months ago Up 9 hours 0.0.0.0:3308->3306/tcp mysql8
60d325c743c4 mysql-57 "container-entrypo..." 6 months ago Up 9 hours 0.0.0.0:3306->3306/tcp mysql57
134已打開遠程端口。通過137查看134的容器和137自己的容器
[root@docker137 ~]# docker -H 192.168.72.134 ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4f191cbd3c26 redis "docker-entrypoint..." 6 months ago Up 9 hours 0.0.0.0:6379->6379/tcp some-redis

136服務器未打開端口，響應錯誤提示信息
[root@localhost ~]# docker -H 192.168.72.136 ps
error during connect: Get http://192.168.72.136:2375/v1.26/containers/json: dial tcp 192.168.72.136:2375: getsockopt: no route to host
