When it comes to deploying resources in Kubernetes, two commonly used commands are `kubectl apply` and `kubectl create`. Both commands serve the purpose of creating resources in a Kubernetes cluster, but they have some key differences that developers should be aware of. In this article, we will compare `kubectl apply` vs `kubectl create` and discuss when to use each command.

`kubectl create` is a command that is used to create a resource in a Kubernetes cluster. When you use `kubectl create`, you are essentially telling Kubernetes to create a new resource based on the YAML or JSON file that you provide. This command is useful for quickly creating resources in a cluster, but it has some limitations. For example, if you try to create a resource that already exists in the cluster, `kubectl create` will return an error and not update the existing resource.

On the other hand, `kubectl apply` is a more powerful command that is used to create or update resources in a Kubernetes cluster. When you use `kubectl apply`, Kubernetes will compare the resource in the YAML or JSON file that you provide with the existing resource in the cluster. If the resource already exists, `kubectl apply` will update the resource with the changes specified in the file. This makes `kubectl apply` a more versatile command for managing resources in a Kubernetes cluster.

So when should you use `kubectl apply` vs `kubectl create`? The answer depends on your specific use case. If you are creating a new resource in a cluster and you are certain that the resource does not already exist, `kubectl create` may be the quicker option. However, if you are deploying resources that may need to be updated or modified in the future, `kubectl apply` is the better choice.

For potential clients of a software development company, understanding the differences between `kubectl apply` and `kubectl create` can be crucial for managing resources in a Kubernetes cluster. By using `kubectl apply`, developers can ensure that their resources are always up-to-date and in sync with the desired state. This can help to prevent errors and inconsistencies in the cluster, ultimately leading to a more stable and reliable deployment process.

In conclusion, while both `kubectl apply` and `kubectl create` are useful commands for creating resources in a Kubernetes cluster, `kubectl apply` offers more flexibility and power for managing resources. By understanding when to use each command, developers can streamline their deployment process and ensure that their resources are always in the desired state.
