[BETA] Deploying to Kubernetes
WARNING! This is a new sub-generator, of BETA quality. Use it at your own risk! Feedback is highly welcome!
This sub-generator allows deployment of your JHipster application to Kubernetes.
- Cassandra is not supported yet
- ELK with JHipster Console is not supported yet
- Consul is not supported yet
You have to install:
You must have a Docker registry. If you don’t have one, you can use the official Docker Hub
Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day.
You can use it to test your application before pushing it to Kubernetes.
Running the sub-generator
To generate config files for Kubernetes, run this command in a new folder:
Then answer all the questions to deploy your application.
Which type of application would you like to deploy?
Your type of application depends on whether you wish to deploy a microservices architecture or classical applications.
Enter the root directory where your applications are located
Enter the path.
Which applications do you want to include in your Kubernetes configuration?
Select your applications.
Enter the admin password used to secure the JHipster Registry admin
This question is only displayed if you choose microservices architecture.
What should we use for the Kubernetes namespace?
See the documentation on namespace here
What should we use for the base Docker repository name?
If you choose Docker Hub as main registry, it will be your Docker Hub login.
What command should we use for push Docker image to repository?
The default command to push to Docker Hub is
For example, if you use the Google Cloud to host your Docker images, it will be:
gcloud docker push
Updating your deployed application
Preparing a new deployment
When your application is already deployed, you can re-deploy it by building a new Docker image:
./mvnw package -Pprod -DskipTests docker:build
Or when using gradle:
./gradlew -Pprod bootRepackage buildDocker -x test
Pushing to Docker Hub
Tag locally your image:
docker tag application username/application
Push your image to Docker Hub:
docker push username/application
Deploying the application
Deploy your application
kubectl apply -f application
