Create A Pod With Multiple Images In Kubernetes

In this article, we will create a pod with multiple images in Kubernetes.

Prerequisite

The first requirement is to install Docker. The second requirement depends on what you are using. If you are using the Kind tool for Kubernetes then install the following: -

Kind tool
Create a multinode cluster
Install Kubectl using the following command: -

snap install kubectl --classic

If you are not using the kind tool and are using different virtual machines, then you can install the following: -

Create A Pod With Multiple Images

For this article, we will create a pod with Python and Redis images. The first step is to create the YAML file.

apiVersion: v1
kind: Pod
metadata:
  name: python-redis-pod
spec:
  containers:
  - name: python-container
    image: python:3.9
    command: ["python", "-c"]
    args:
      - |
        import time
        while True:
          print("Python Application is running")
          time.sleep(5)

  - name: redis-container
    image: redis:latest
    ports:
    - containerPort: 6379

Once the YAML file is created, execute the following command to create the pod.

kubectl apply -f python-redis-pod.yaml

In the above code, python-redis-pod.yaml is the name of the YAML file.
