Walk through a Kubernetes deployment in this one, bruh!


Go through a Kubernetes deployment…

A Kubernetes deployment is a process of creating and managing a desired state of one or more pods in a cluster. Here’s a general overview of the steps that would be taken to perform a deployment in Kubernetes:

  1. Create a container image: The first step in deploying an application to Kubernetes is to create a container image of the application. This can be done using a tool like Docker, which allows developers to package their application and its dependencies into a lightweight and portable container.
  2. Push the container image to a container registry: Once the container image is created, it needs to be pushed to a container registry such as Docker Hub, Google Container Registry, or Amazon Elastic Container Registry. This allows the image to be easily pulled and run by the Kubernetes cluster.
  3. Create a Kubernetes deployment configuration file: The next step is to create a Kubernetes deployment configuration file, which defines the desired state of the application in the cluster. This file typically includes information such as the number of replicas of the application to be run, the container image to be used, and any environment variables that need to be passed to the application.
  4. Apply the deployment configuration: Once the deployment configuration file is created, it can be applied to the cluster using the kubectl command-line tool. This tells the cluster to create or update the desired state defined in the file.
  5. Monitor the deployment: After the deployment configuration has been applied, the status of the deployment can be monitored using the kubectl command-line tool or a Kubernetes dashboard. This allows the DevSecOps teams to ensure that the application is running as expected and to identify and troubleshoot any issues that may arise.
  6. Scale the deployment: If necessary, the number of replicas of the…
