In the previous article, we introduced how to pass Nocalhost Rapid development of Rainbond Microservices on , Introduced the basic development process .

This article will continue to introduce , Use Nocalhost Development profile Achieve the following ：

  • Onekey Run and long-range Debug
  • Persistent configuration
  • Development container resource limitations
  • Port forwarding

What is development configuration ？

Development configuration is around Development mode To carry out , For example, what image is used to enter Development mode , Whether you need to turn on persistence to save the contents of the development container , Which files are synchronized into the development container , How to debug with one click 、 Run the services in the container with one click . After configuring the correct and appropriate development configuration , Can be used in Nocalhost Development mode It's more handy when it comes to .

Deploy Rainbond + SpringCloud

Next, continue to the above article SpringCloud Pig For example , debugging Java Maven Service Pig-auth modular .

project Gitee Address ：https://gitee.com/zhangbigqi/pig

Deploy Rainbond

I won't go into details here Rainbond Installation , see also be based on Linux install Rainbond.

Deploy SpringCloud

We are Rainbond After docking with the open source app store , Search in the open source app store Spring Cloud Pig install 3.5.0 edition .

The English name of the application component installed from the app store is an automatically generated string , We need to set the English name of the component （Deployment Name）, adopt Nocalhost When connecting to the cluster, you can distinguish clearly Deployment Corresponding components .

Nocalhost docking Rainbond

  1. install Nocalhost JetBrains Plugin plug-in unit , See documentation install Nocalhost JetBrains Plugin plug-in unit .

  2. obtain K8s Kubeconfig, See documentation obtain Kubeconfig file .

  3. stay pig Under the namespace , Find the workload pig-auth Right click and choose Dev Config （ Development configuration ）

  1. Copy the following configuration file to Dev Config in .
# Deployment Name

name: pig-auth

serviceType: deployment

containers:

	# Deployment  Main container name 

  - name: auth

    dev:

    	#  Developing mirroring , The image contains  Java Maven  Environmental Science 

      image: registry.cn-hangzhou.aliyuncs.com/zqqq/maven:3.8.6-openjdk-8

      #  The default terminal is  bash

      shell: bash

      # Rainbond  Provided  StorageClass Name

      storageClass: rainbondvolumerwx

      #  Configure development container resources 

      resources:

        limits:

          memory: 4096Mi

          cpu: "2"

        requests:

          memory: 2048Mi

          cpu: "1"

      persistentVolumeDirs:

      	# Maven  Depend on the package cache path , coordination  storageClass  Eat together 

        - path: /root/.m2/repository

          capacity: 10Gi

      command:

        #  One click start command , Install dependent packages and start  pig-auth  Sub module 

        run:

          - mvn

          - install

          - '&&'

          - mvn

          - spring-boot:run

          - -pl

          #  Specify sub module startup 

          - pig-auth

        #  Onekey  Debug  command , Install dependent packages and  Debug pig-auth  Sub module 

        debug:

          - mvn

          - install

          - '&&'

          - mvn

          - spring-boot:run

          - -pl

          #  Specify sub module startup 

          - pig-auth

          # Java Debug  command 

          - -Dspring-boot.run.jvmArguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005

      debug:

        #  Remote port , Corresponding Debug In the command  address=5005

        remoteDebugPort: 5005

        #  choice  Java  Language 

        language: java

      #  Thermal loading 

      hotReload: true

      #  File synchronization 

      sync:

        type: send

        mode: gitIgnore

        deleteProtection: true

      #  Port forwarding , Forward... In the container 3000 Port to local 3999

      portForward:

        - 3999:3000

Onekey Run

  1. Right click workload pig-auth .
  2. choice Remote Run.
  3. Nocalhost Will automatically enter DevMode And implement Remote Run.

Onekey Debug

  1. Right click workload pig-auth .
  2. choice Remote Debug.
  3. Nocalhost Will automatically enter DevMode And implement Remote Debug.
  4. Put a breakpoint in the code , Initiate request , Get into IDE Debug Pattern .

Persistent configuration

At development time , Most of the files we want to persist are Dependency package journal , This article also caches Java The dependency package of .

rainbondvolumerwx yes Rainbond The storage class provided by default , After filling in the following configuration, it will be automatically created under the current namespace PVC, as follows ：

storageClass: rainbondvolumerwx

persistentVolumeDirs:

  - path: /root/.m2/repository

    capacity: 10Gi

Container resource limit

Limit the resources of the development container , Quota can maximize the resource utilization of the server , You can modify it through the following development configuration ：

resources:

  limits:

    memory: 4096Mi

    cpu: "2"

  requests:

    memory: 2048Mi

    cpu: "1"

Port forwarding

Forward container port to local , You can modify it through the following development configuration ：

portForward:

  - 3999:3000 		#  Forwarding container  3000  Port to local  3999  port

Last

Of course Nocalhost You can debug multiple microservices at the same time , In the same way, you only need to modify Deployment Name and Containers Name And the sub module of microservice .

Nocalhost There are also some things that are not mentioned in the development configuration article , such as ： Development environment variables 、 Two modes of file synchronization patterngitignore wait , also Nocalhost Support for multiple languages ,Java It's just one of them , Guys can explore on their own .

Nocalhost + Rainbond Let's develop 、 More efficient deployment 、 convenient .
