1. 依赖版本#

版本:

  • kind 0.14.0
  • docker 20.10.17
  • node v14.19.3

注意：

  • 1.先确保前后端能够正常编译

  • 2.确保组件依赖版本

  • 3.kind是用docker容器模拟节点的 机器重启回来容器都变了 调度器就不工作了 这个是kind的limitation,官方文档有详细说明。

2.安装docker#

2.1 安装教程#

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
systemctl start docker
systemctl enable docker

2.2 设置国内镜像#

vi /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"],
"insecure-registries": ["https://registry.mydomain.com","http://hub-mirror.c.163.com"]
}

3. 安装kind#

（1）手工下载kind二进制

https://github.com/kubernetes-sigs/kind/releases

（2）安装kind二进制

chmod +x ./kind
mv kind-linux-amd64 /usr/bin/kind

4. 安装JDK 和 Maven#

（1）参考通用安装教程，安装如下组件

jdk 1.8

mavne 3.5+

5. 安装NodeJS#

（1）安装版本

node v14.19.3

（2）安装nvm

export http_proxy=http://10.0.0.150:7890
export https_proxy=http://10.0.0.150:7890
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

（3）安装nodejs

nvm ls-remote
nvm install v14.19.3

（4）配置NPM

npm config set registry https://registry.npmmirror.com
npm config set sass_binary_site https://registry.npmmirror.com/binary.html?path=node-sass/

（5）编译前端

npm install -g yarn
yarn
yarn build
yarn

6. 编译linkis#

\# 1. When compiling for the first time, execute the following command first
./mvnw -N install
\# 2. make the linkis distribution package
\# - Option 1: make the linkis distribution package only
./mvnw clean install -Dmaven.javadoc.skip=true -Dmaven.test.skip=true
\# - Option 2: make the linkis distribution package and docker image
./mvnw clean install -Pdocker -Dmaven.javadoc.skip=true -Dmaven.test.skip=true
\# - Option 3: linkis distribution package and docker image (included web)
./mvnw clean install -Pdocker -Dmaven.javadoc.skip=true -Dmaven.test.skip=true -Dlinkis.build.web=true

7. 创建集群#

dos2unix ./linkis-dist/helm/scripts/*.sh
./linkis-dist/helm/scripts/create-test-kind.sh

8. 安装helm charts#

 ./scripts/install-charts.sh linkis linkis-demo

9.访问linkis页面#

kubectl port-forward -n linkis  --address=0.0.0.0 service/linkis-demo-web 8087:8087
http://10.0.2.101:8087

10.使用Linkis客户端测试#

kubectl -n linkis exec -it linkis-demo-ps-publicservice-77d7685d9-f59ht -- bash./linkis-cli -engineType shell-1 -codeType shell -code "echo \"hello\" "  -submitUser hadoop -proxyUser hadoop

11.安装kubectl#

cat <<EOF > /etc/yum.repos.d/kubernetes.repo[kubernetes]name=Kubernetesbaseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/enabled=1gpgcheck=1repo_gpgcheck=1gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpgEOF
yum install -y --nogpgcheck kubectl
kubectl config view  查看集群信息kubectl config get-contexts  得到所有集群context对象信息kubectl cluster-info  查看当前集群情况
