Run 'kubectl get nodes' on the control-plane to see this node join the cluster.
3.3 构建CI/CD流水线
3.3.1 使用Jenkins部署应用
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'docker build -t fgedu/app:${BUILD_NUMBER} .'
}
}
stage('Test') {
steps {
sh 'docker run --rm fgedu/app:${BUILD_NUMBER} npm test'
}
}
stage('Deploy') {
steps {
sh 'docker push fgedu/app:${BUILD_NUMBER}'
sh 'kubectl set image deployment/fgedu-app fgedu-app=fgedu/app:${BUILD_NUMBER}'
}
}
}
}

# 运行Docker hello-world
docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
