Compose 编排 SpringCloud微服务

将 Eureka 等微服务运行在 Docker 容器中

通过 Docker Compose 启动、停止

现在我们开始学习如何通过 Docker-Compose 组合编排运行多个微服务。

将 Eureka 等微服务运行在 Docker 容器中

构建 Eureka Server 镜像

1 2	`cd microservice-eureka-server` `mvn clean` `package` `-DskipTests && mvn dockerfile:build`

构建用户服务镜像

1 2	`cd microservice-provider-user` `mvn clean` `package` `-DskipTests && mvn dockerfile:build`

构建电影服务镜像

1 2	`cd microservice-consumer-movie` `mvn clean` `package` `-DskipTests && mvn dockerfile:build`

查看镜像

1	`docker images`

会发现如下三个镜像：

REPOSITORY                                 TAG                 IMAGE ID            CREATED              SIZE
microservice-consumer-movie                0.0.1-SNAPSHOT      20c107a27dc3        44 seconds ago       139MB
microservice-provider-user                 0.0.1-SNAPSHOT      5d9c9d1e959a        About a minute ago   139MB
microservice-eureka-server                 0.0.1-SNAPSHOT      5621f990e5d5        4 minutes ago        128MB
