SpringBoot Docker部署

1.编写Dockerfile

进入项目目录：

cd /var/apps/my-app

编写Dockerfile

vim Dockerfile

Dockerfile文件内容

# 基镜像java8FROM java:8# 作者MAINTAINER jeikerxiao# 添加my-app-0.0.1.jar 到容器镜像中，并重命名 app.jarADD my-app-0.0.1.jar app.jar# 运行容器，监听8080端口EXPOSE 8080# 启动时运行 java -jar app.jarENTRYPOINT ["java","-jar","/app.jar"]

2.编译镜像

build当前目录下的Dockerfile 文件，命名为wisely/my-app。

➜ docker build -t wisely/my-app .

3.查看镜像

➜ docker images

REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZEwisely/my-app              latest              f6a29955727e        4 minutes ago       672MBjava                       8                   d23bdf5b1b1b        5 months ago        643MBhello-world                latest              48b5124b2768        5 months ago        1.84kB

4.运行镜像

运行命令，–name 重命名：-p 端口暴露 当前服务器端口：容器端口 镜像名。

➜ docker run -d --name my-app -p 8088:8080 wisely/my-app

5.查看容器状态

➜ docker ps

CONTAINER ID        IMAGE             COMMAND                CREATED             STATUS              PORTS                    NAMEScb9022fd451e        wisely/my-app     "java -jar /app.jar"   12 seconds ago      Up 10 seconds       0.0.0.0:8088->8080/tcp   my-app
