使用IDEA官方docker插件构建镜像

此方法同样适用于jetbrains系列的其他开发软件

在IDEA中，如果是maven项目，可以使用插件

<plugin><groupId>com.spotify</groupId><artifactId>docker-maven-plugin</artifactId><version>1.2.2</version>
</plugin>

或者

<plugin><groupId>com.spotify</groupId><artifactId>dockerfile-maven-plugin</artifactId><version>1.4.13</version>
</plugin>

来构建docker镜像，不过还是有些繁琐，可以结合IDEA官方的docker插件，直接快速构建镜像

1 准备

安装docker，Windows可以安装Docker Desktop，CentOS可以参考我之前的文章：CentOS安装docker，安装完成后，需要开启远程访问

1.1 CentOS

vi /usr/lib/systemd/system/docker.service# 在 ExecStart 后加上参数-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

完整信息如下

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
Requires=docker.socket containerd.service[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always# 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
