Deploying to Minikube

If you have no existing installation of Minikube on your computer, follow the official tutorial.

When Minikube is installed, start the cluster:

minikube start --addons registry --addons dashboard

The previous command starts Minikube with a Docker registry (we’ll use it in the next step) and with the Kubernetes dashboard.

If you use Mac or Windows, refer to the documentation to learn how to expose the Docker registry installed as an addon on the port 5000 of the host.

Finally, install Helm. We’ll use it to deploy the application in the cluster thanks to the chart provided in the API Platform distribution.

First, build the images:

docker build -t localhost:5000/php api --target api_platform_php
docker build -t localhost:5000/caddy api --target api_platform_caddy
docker build -t localhost:5000/pwa pwa --target api_platform_pwa_prod

Then push the images in the registry installed in Minikube:

docker push localhost:5000/php
docker push localhost:5000/caddy
docker push localhost:5000/pwa

Finally, deploy the project using the Helm chart:

$ helm install my-project helm/api-platform \
  --set php.image.repository=localhost:5000/php \
  --set php.image.tag=latest \
  --set caddy.image.repository=localhost:5000/caddy \
  --set caddy.image.tag=latest \
  --set pwa.image.repository=localhost:5000/pwa \
  --set pwa.image.tag=latest

Copy and paste the commands displayed in the terminal to enable the port forwarding then go to http://localhost:8080 to access your application!

Run minikube dashboard at any moment to see the state of your deployments.

Skaffold is a tool for Kubernetes development: https://skaffold.dev/.

It will build and deploy automatically your app in Kubernetes and apply every changes. The default configuration use minikube and helm. More configurations are available in Skaffold documentation.

First, install the skaffold CLI.

Then, run minikube:

minikube start

Add Skaffold configuration in the file ./helm/skaffold.yaml. You can find a complete configuration file for minikube with its Helm values override.

Finally, go to the helm folder, and run skaffold in dev mode:

cd ./helm
skaffold dev
