doctl-kubernetes-cluster:tldr:5ecd8

This command is used to create a new Kubernetes cluster using the DigitalOcean command-line interface (CLI) tool, doctl.

Here's the breakdown of each part of the command:

• doctl kubernetes cluster create: This is the base command to create a Kubernetes cluster using doctl.

• --count ${3}: This flag specifies the number of worker nodes to create in the cluster. In this case, it uses the value stored in the variable ${3}. You would need to replace ${3} with the actual number you want.

• --region ${nyc1}: This flag specifies the region where the cluster will be created. It uses the value stored in the variable ${nyc1}. You need to replace ${nyc1} with the desired region, like nyc1 for New York region.

• --size ${s-1vcpu-2gb}: This flag sets the size of each worker node in the cluster. It uses the value stored in the variable ${s-1vcpu-2gb}. You need to replace ${s-1vcpu-2gb} with the desired size, like s-1vcpu-2gb for a machine with 1 vCPU and 2GB RAM.

• --version ${latest}: This flag specifies the Kubernetes version to use in the cluster. It uses the value stored in the variable ${latest}. You can replace ${latest} with the desired version or keep it as ${latest} to use the latest stable version.

• ${cluster_name}: This is the name you provide for your Kubernetes cluster. You need to replace ${cluster_name} with your desired cluster name.

Putting it all together, the command creates a Kubernetes cluster with a specified number of worker nodes, in a specific region, with a certain node size and version, and assigns it the provided cluster name.
