springboot之docker化
1、Docker安装
本人是centos7系统,安装也是按照官方文档进行安装。https://docs.docker.com/install/linux/docker-ce/centos/ ,即 1、sudo yum install -y yum-utils \ device-mapper-persistent-data \ lvm2 2、sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo 3、sudo yum-config-manager --enable docker-ce-nightly 4、sudo yum install docker-ce docker-ce-cli containerd.io 5、yum list docker-ce --showduplicates | sort -r 6、sudo yum install docker-ce-18.09.1 docker-ce-cli-18.09.1 containerd.io 7、sudo systemctl start docker 8、sudo docker run hello-world
--------docker-compose安装
官网:https://docs.docker.com/compose/install/compose-plugin/#installing-compose-on-linux-systems
1、curl -SL https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
2、chmod +x/usr/local/bin/docker-compose
3、sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
2、配置docker远程连接端口 (注意斜杠)
vim /usr/lib/systemd/system/docker.service
添加: -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
3.重启docker
systemctl daemon-reload
systemctl start docker
4、idea安装插件
5、填写远程docker地址
6、连接远程docker
7、创建一个springboot项目,这里不做介绍了
8、springboot pom配置文件

9、在src/main目录下创建docker目录,并创建Dockerfile文件
FROM openjdk:8-jdk-alpine ADD *.jar app.jar ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
10、添加docker启动
具体解释:
-
Image tag : 指定镜像名称和tag,镜像名称为 docker-demo,tag为1.1
-
Bind ports : 绑定宿主机端口到容器内部端口。格式为[宿主机端口]:[容器内部端口]
-
Bind mounts : 将宿主机目录挂到到容器内部目录中。
格式为[宿主机目录]:[容器内部目录]。这个springboot项目会将日志打印在容器 /home/developer/app/logs/ 目录下,将宿主机目录挂载到容器内部目录后,那么日志就会持久化容器外部的宿主机目录中。
11、maven打包:先clean再package,如果是SUCESS,则可以进行下一步运行
12、运行
如果没有报错,则可以在centos上执行命令,看容器是否已经运行。
