docker环境配置
一.docker远程环境配置
1.1 完成docker安装
参照：centos docker 安装指南
1）卸载老版本docker文件
$ sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
2）安装yum工具包
$ sudo yum install -y yum-utils
3）设置docker镜像仓库
$ sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
4）安装docker engine
$ sudo yum install docker-ce docker-ce-cli containerd.io
- 启动docker
$ sudo systemctl start docker
docker 安装结束。
1.2 docker配置
1）docker开启远程API
方式一：
使用vi编辑器修改docker.service文件
vi /usr/lib/systemd/system/docker.service
修改
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
为
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
方式二
在daemon.json中添加
"hosts":["tcp://0.0.0.0:2375","unix:///var/run/docker.sock"]
2）重启docker服务
$ systemctl restart docker
使用方式二需要在重启前执行：systemctl daemon-reload
3）开通防火墙
$ firewall-cmd --zone=public --add-port=2375/tcp --permanentfirewall-cmd --reload
1.3 Docker支持http上传镜像
不上传可不进行配置
1）在daemon.json中添加
"insecure-registries":["192.168.0.43:8082"]
2）重启docker服务
$ systemctl daemon-reload
$ systemctl restart docker
二、本地环境配置
2.1 window系统添加环境变量
2.2 pom.xml引入插件
- dockerfile-maven-plugin

2）编写Dockerfile
可参考：Dockerfile指南
FROM java:8
ARG JAR_FILE
ADD target/${JAR_FILE} /app.jar
ENTRYPOINT ["java", "-jar","/app.jar"]
3）使用mvn clean package进行镜像打包上传
