Projeto exemplo Docker e Kubernetes

Comandos básicos Docker (https://docs.docker.com/reference/)

docker build -t (your-image):(your-tag) .
docker build -t (your-image):latest -t (your-image):(your-tag) .
docker images
docker ps
docker rmi -f #image
docker pull #image
docker push #image
docker run --rm -it -d -p 8181:8181 --name (name-container) (your-image):(your-tag)

docker exec -it (container-id) /bin/bash
docker info
docker context create fittipaldi-server2 --docker "host=tcp://172.21.35.113:2375"
docker-compose up -d

Comandos básicos kubernetes

kubectl config view
kubectl proxy
kubectl create deployment (your-deployment) --image=(your-image) --port=8181 -r=3 --dry-run=client -o yaml> k8s/deploy.yml
kubectl create service clusterip (your-service) --tcp=8181 --dry-run=client -o yaml > k8s/service.yml
kubectl expose deployment (your-deployment) --port=8181 --target-port=8181 --type=LoadBalancer --name=(name-service)
kubectl apply -f deploy.yml
kubectl get deployment
kubectl get deployment -o wide
kubectl get all
kubectl get pods
kubectl describe pods
kubectl delete pod
kubectl apply -f service.yml
kubectl port-forward (your-service) 8181
kubectl delete all -l app=(your-app)
kubectl delete (your-service)
kubectl get services
kubectl run (your-deployment) --image=(your-image) --replicas=10
kubectl scale deployment (your-deployment) --replicas=10
kubectl autoscale deployment (your-deployment) --cpu-percent=50 --min=1 --max=10

Comandos Maven + Autoincrement

${project_loc:}

mvn build-helper:parse-version versions:set -DgenerateBackupPoms=false -DnewVersion=${parsedVersion.majorVersion}.${parsedVersion.minorVersion}.${parsedVersion.nextIncrementalVersion}-SNAPSHOT

Reset Builds Jenkins

item = Jenkins.instance.getItemByFullName(pipeline-name)

//THIS WILL REMOVE ALL BUILD HISTORY
item.builds.each() { build ->
build.delete()
}
item.updateNextBuildNumber(1)
