Prerequisites

Before getting started, you will need to have the following:

  • A Kubernetes cluster up and running
  • A Docker image of your application

Commands Used in Video

Follow the commands below to use environment variables in Kubernetes:

Step 1: Build your Docker image by running the following command:

docker build -t wordpress .

Step 2: Apply your YAML files by running the following command:

kubectl apply -f <file-name>

Step 3: To see the list of pods, run the following command:

kubectl get pods

Step 4: To check the logs of a pod, run the following command:
