🛠 CTO.ai maintained Kubernetes OP 🚀

A collection of common interactive command line user interfaces to setup and maintain a new kubernetes cluster.

Creating and maintaining a production-grade kubernetes cluster will incur you charges

Commands

All commands start with ops run k8s. From there, you can run the following commands to interact with your AWS-hosted Kubernetes cluster

Things you need to do the following commands successfully:

• AWS accessKeyId: Can be obtained from the IAM section on your AWS console
• AWS accessKeySecret: Can be obtained from the IAM section on your AWS console
• Cluster Name: The name of the cluster you might want to deploy
• Region: The region you want to deploy the cluster to
• [Optional] Domain: For private clusters, you would need your own domain and hosted zone
• [Optional] SSH key pair in your ~/creds folder named cluster_rsa and cluster_rsa.pub for private clusters. For more information, see Generating SSH Key Pair

Create

• Will create a new kubernetes cluster for in an AWS account for you
• Takes about ~15 minutes to finish successfully

Destroy

• Will delete a cluster that has been deployed in an AWS account

Update

• Allows you to scale the number and instance size of worker nodes in the cluster
• Takes about ~15 minutes to finish successfully

You would also need:

• Instance size: The size you want to upgrade the worker node size to
• Node Count: How many worker nodes you want the cluster to have after the update

Generate-Resources

• Allows you to deploy you app to the cluster. It can also deploy any docker image.

You would need:

• A docker image containing your application
• That image must be exposed at a certain port if you want to make it public

Notes

The Op name would be k8s, instead of kubernetes-ops. Please take note of this when publishing the op, as it would be under k8s.
