05 - Skaffold

The inner development loop on Kubernetes requires several steps: compiling the application, building the image, loading it to the cluster, and deploying it. We'll automate it with Skaffold.

Warning Skaffold support for ARM64 architectures is not stable. I recommend choosing Tilt over Skaffold in that case.

Let's use a local cluster provisioned with kind.

cd ..
./create-cluster.sh

Basic

Navigate to the basic folder.

cd 05-skaffold/basic/book-service

Run Skaffold to start the automated inner development loop on Kubernetes.

skaffold dev --port-forward

Now you can work with the application, save your changes, and they will be automatically loaded into the container running in Kubernetes. You can also debug it by attaching a remote debugger from your IDE to the Pod by starting Skaffold with skaffold debug.

The Skaffold setup in the skaffold.yml file is tuned to work with Visual Studio Code without any additional configuration.

If you use IntelliJ IDEA, refer to the official documentation to enable live reload in the IDE. You also need to update the skaffold.yml file and change the folders monitored by Skaffold for the live reload functionality. For more information on how it works, refer to the Paketo official documentation.

Clean-up

When you're done, delete the cluster as follows.

cd ../../..
./destroy-cluster.sh
