Problem Description

The docs currently does not list all the AI Cache Provider that are available in K8sGPT:
https://docs.k8sgpt.ai/explanation/caching/

The following backends are missing:

Microsoft Azure blob
Google Cloud Storage

Solution Description

I will create a pull request and link it to this issue, which will include the documentation for the missing cache providers.

And

1. The doc doesn't explicitly explain how AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY applied to the command. Doc should explain these are set and required as environmental variables in CLI.
2. The same issue with the CLI tool: in the k8sgpt cache add --help, it doesn't tell you how to pass ACCESS_KEY & SECRET_ACCESS
3. The CLI command itself doesn't show available correct keys in help k8sgpt cache add --help they are simply not there:

k8sgpt cache add --help

This command allows you to add a remote cache to store the results of an analysis.
        The supported cache types are:
        - Azure Blob storage
        - Google Cloud storage
        - S3

Documentation should have this info from the README:

Adding a remote cache

• AWS S3
  • As a prerequisite AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY are required as environmental variables.
  • Configuration, k8sgpt cache add s3 --region <aws region> --bucket <name>
    • K8sGPT will create the bucket if it does not exist
• Azure Storage
  • We support a number of techniques to authenticate against Azure
  • Configuration, k8sgpt cache add azure --storageacc <storage account name> --container <container name>
    • K8sGPT assumes that the storage account already exist and it will create the container if it does not exist
    • It is the user responsibility have to grant specific permissions to their identity in order to be able to upload blob files and create SA containers (e.g Storage Blob Data Contributor)
• Google Cloud Storage
  • As a prerequisite GOOGLE_APPLICATION_CREDENTIALS are required as environmental variables.
  • Configuration, k8sgpt cache add gcs --region <gcp region> --bucket <name> --projectid <project id>
    • K8sGPT will create the bucket if it does not exist
