idea集成docker

修改docker.service

vim /usr/lib/systemd/system/docker.service

修改ExecStart这一行，开启2375端口远程访问

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes

# kill only the docker process, not all processes in the cgroup
KillMode=process
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

说明: Intelli] IDEA通过2375端口远程连接到Linux系统中的Docker.
重载配置并重启docker服务

systemctl daemon-reload && systemctl restart docker

3、开放端口

firewall -cmd --zone=public --add-port=2375/tcp --permanent && firewall -cmd --reload

测试接口

curl http://192.168.3.100:2375/version

看到类似如下内容

[WARNING] No entry found in settings.xml for serverId=docker-mx, cannot configure authentication for that registry

出现这个警告是因为settings.xml文件没有配置镜像仓库登录账号密码信息

将 credsStore 改成 credStore ，但是别重启本地docker，否则这一项配置会被清除
