1.父级build.gradle

注：gradle-docker-plugin下载比较缓慢，可以从中央仓库下载下来之后传到本地私服

buildscript {
 
    ext {
        springBootVersion = '2.2.1.RELEASE'
    }
    repositories {
        maven {
            url =  "http://192.168.6.135:8081/nexus/content/groups/public/"
        }
    }
 
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
        classpath('com.bmuschko:gradle-docker-plugin:6.1.1')
    }
}

2.需要打包的子build.gradle

    apply plugin: "com.bmuschko.docker-spring-boot-application"
    dependencies {
    }
    docker {
        //如果url不指定的话
        // Unix系统默认：unix:///var/run/docker.sock
        //Windows系统默认：tcp://127.0.0.1:2375。
        url = 'http://10.3.192.39:2375'
        registryCredentials {
            url = 'http://10.3.192.39:8777'
            username = 'admin'
            password = 'Harbor12345'
        }
        springBootApplication {
            baseImage = '10.3.192.39:8777/hualongxin/jdk1.8:latest'//指定运行镜像
            ports = [8086]  //暴露的端口
            images = ["10.3.192.39:8777/hualongxin/${project.group}/${project.name}:${version}"]
            jvmArgs = ['-Dspring.profiles.active=$env', '-Xmx2048m', '-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8084']
        }
    }

3.构建镜像

运行task dockerPushImage

4. k8s指定spring profiles

deployment.yaml

kind: Deployment
apiVersion: apps/v1
metadata:
  name: my-spring-boot-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-spring-boot-app
  template:
    metadata:
      labels:
        app: my-spring-boot-app
    spec:
      containers:
        - name: my-spring-boot-app
          image: my-spring-boot-app:1.2.3
          env:
          - name: SPRING_PROFILES_ACTIVE
            value: prod
