Kubectl Apply Vs Create
Kubectl is a command-line tool that is used to interact with Kubernetes clusters. It allows users to manage various aspects of their Kubernetes resources, such as pods, deployments, services, and more. One of the key features of kubectl is the ability to apply changes to existing resources using the `apply` command.
When it comes to managing Kubernetes resources, there are two main commands that users can use: `kubectl apply` and `kubectl create`. While both commands are used to create or update resources in a Kubernetes cluster, there are some key differences between the two.
The `kubectl create` command is used to create new resources in a Kubernetes cluster. When a resource is created using `kubectl create`, the command will generate a new resource definition and submit it to the Kubernetes API server. This means that `kubectl create` is a one-time operation that creates a resource in the cluster based on the provided definition.
On the other hand, the `kubectl apply` command is used to apply changes to existing resources in a Kubernetes cluster. When a resource is updated using `kubectl apply`, the command will compare the current state of the resource with the desired state defined in the resource definition. If there are any differences between the two states, `kubectl apply` will make the necessary changes to bring the resource in line with the desired state.
One of the key benefits of using `kubectl apply` over `kubectl create` is that it allows for declarative configuration management. This means that users can define the desired state of their resources in a resource definition file and apply those changes to the cluster using `kubectl apply`. This makes it easier to manage and update resources in a Kubernetes cluster, as users can simply update the resource definition file and reapply the changes using `kubectl apply`.
Another advantage of using `kubectl apply` is that it supports partial updates. This means that users can apply changes to specific fields or sections of a resource without affecting the rest of the resource. This can be useful when making small updates or modifications to resources in a Kubernetes cluster, as it allows users to make targeted changes without having to recreate the entire resource.
In conclusion, while both `kubectl apply` and `kubectl create` are used to create or update resources in a Kubernetes cluster, `kubectl apply` offers more flexibility and control when it comes to managing resources. By allowing for declarative configuration management and supporting partial updates, `kubectl apply` is a powerful tool for managing resources in a Kubernetes cluster.
