使用Maven构建Docker镜像

使用Maven构建Docker镜像 一、安装Docker

yum install docker-ce

[root@localhost ~]# docker version
Client: Docker Engine - Community
 Version:           20.10.12
 API version:       1.41
 Go version:        go1.16.12
 Git commit:        e91ed57
 Built:             Mon Dec 13 11:45:41 2021
 OS/Arch:           linux/amd64
 Context:           default
 Experimental:      true

Server: Docker Engine - Community
 Engine:
  Version:          20.10.12
  API version:      1.41 (minimum version 1.12)
  Go version:       go1.16.12
  Git commit:       459d0df

  Version:          1.0.2

 docker-init:
  Version:          0.19.0
  GitCommit:        de40ad0

二、开通Docker的远程Api端口2375

# 1、在ExecStart下，增加 -H tcp://0.0.0.0:2375
vi /lib/systemd/system/docker.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:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always


# 2、保存，然后输入以下命令，重新加载配置和重启
systemctl daemon-reload 
systemctl restart docker

三、开放防火墙端口

firewall-cmd --add-port=2375/tcp
firewall-cmd --add-port=2375/tcp --permanent

四、配置docker_host环境变量

  注意：IDE工具如果早于环境变量配置前打开了；最好在配置环境变量后，将IDE关闭重新打开。不然maven_docker连接地址还是本地的127.0.0.1:2375

五、使用Maven构建Docker镜像

执行如图所示，进行maven打包：

# maven打包成功后即可见到镜像
[root@localhost ~]# docker images
REPOSITORY                           TAG       IMAGE ID       CREATED          SIZE

ms-sailfish/register-center-server   v0.0.1    4a717ca6f02f   17 minutes ago   735MB
