Apply for Kubernetes

📢 Make sure you have set up a Kubernetes cluster and have connected to it.

📢 Make sure you have read the k8s-image-pull-secrets.md document. imagePullSecrets will be used in subsequent operations.

Replace the Image Pull Credentials

Open the deployment/base.yaml file and replace the content at the .dockerconfigjson key with your credentials.

For specific operations, please refer to k8s-image-pull-secrets.md

Apply Some Basics

This operation will create a new Namespace, Secret, and Service.

Here, denostr will be used as the namespace, denostr-svc as the service name, and ghcr as the image pull secret name.

kubectl apply -f deployment/base.yaml

Deploy StatefulSet

This operation will create a new StatefulSet and ConfigMap.

Here, ConfigMap is used as the startup configuration item. You can customize any parameters in the configuration, but this is not the main job.

As a required dependency for the application, MongoDB must be replaced with the environment variable MONGO_URI in spec.template.spec.containers[].env[].name of the StatefulSet.

kubectl apply -f deployment/worker.yaml

# Paid enabled, please execute this command
kubectl apply -f deployment/maintenance.yaml

Wait a few minutes to ensure that the application is running.

Verify deployment

kubectl get sts -n denostr
kubectl get svc -n denostr
kubectl get po -n denostr

# or
kubectl get sts,svc,po -n denostr

You should see detailed information about the service and pods in the output.

Congratulations! You have successfully deployed Denostr to Kubernetes.
