Kubernetes Deployment

This article describes how to deploy a Linkis service in a Kind Kubernetes environment for easier learning and debugging.

kind github：https://github.com/kubernetes-sigs/kind
kind web site：kind.sigs.k8s.io/

  • kind 0.14.0
  • docker 20.10.17
  • centos 7.6

  • helm 3.x

    1. Ensure that the component depends on the version
    1. kind means that the machine simulating node with docker container is restarted and the container has changed and the scheduler is not working anymore. This is a kind limitation and there is a detailed explanation in the official document.
  1. sudo yum install -y yum-utils device-mapper-persistent-data lvm2
  2. sudo yum -y install docker-ce
  3. systemctl start docker
  4. systemctl enable docker
  1. https://github.com/kubernetes-sigs/kind/releases
  1. chmod +x ./kind
  2. mv kind-linux-amd64 /usr/bin/kind
  1. apache-linkis-1.3.1-incubating-bin.tar.gz
  1. mkdir -p /opt/data/common/extendlib
  1. curl https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.28/mysql-connector-java-8.0.28.jar -o /opt/data/common/extendlib/[mysql-connector-java-8.0.28.jar](https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.28/mysql-connector-java-8.0.28.jar)
  1. ./bin/install-linkis-to-kubernetes.sh reset
  1. ./bin/install-linkis-to-kubernetes.sh pull -mghcr.dockerproxy.com
  1. ./bin/install-linkis-to-kubernetes.sh install -l -mghcr.dockerproxy.com
  1. kubectl get pods -A

  1. ./helm/scripts/prepare-for-spark.sh
  1. ./helm/scripts/remote-proxy.sh start
  1. linkis-web: http://10.0.2.102:8088/#/login
  2. username:hadoop
  3. Get the password command：
  4. kubectl describe cm linkis-demo-linkis-config -n linkis |grep wds.linkis.admin.password
  5. password:4f90c1b13
