==> Installing k8sgpt from k8sgpt-ai/k8sgpt Error: The following formula cannot be installed from a bottle and must be
built from the source. k8sgpt Install Clang or run brew install gcc.

If you install gcc as suggested, the problem will persist. Therefore, you need to install the build-essential package.

   sudo apt-get update
   sudo apt-get install build-essential

Analysis with serve mode

grpcurl -plaintext -d '{"namespace": "k8sgpt", "explain" : "true"}' localhost:8080 schema.v1.ServerAnalyzerService/Analyze
{
  "status": "OK"
}

Analysis with custom headers

k8sgpt analyze --explain --custom-headers CustomHeaderKey:CustomHeaderValue

With this option, the data is anonymized before being sent to the AI Backend. During the analysis execution, k8sgpt retrieves sensitive data (Kubernetes object names, labels, etc.). This data is masked when sent to the AI backend and replaced by a key that can be used to de-anonymize the data when the solution is returned to the user.

1. Error reported during analysis:

Error: HorizontalPodAutoscaler uses StatefulSet/fake-deployment as ScaleTargetRef which does not exist.

2. Payload sent to the AI backend:

Error: HorizontalPodAutoscaler uses StatefulSet/tGLcCRcHa1Ce5Rs as ScaleTargetRef which does not exist.

3. Payload returned by the AI:

The Kubernetes system is trying to scale a StatefulSet named tGLcCRcHa1Ce5Rs using the HorizontalPodAutoscaler, but it cannot find the StatefulSet. The solution is to verify that the StatefulSet name is spelled correctly and exists in the same namespace as the HorizontalPodAutoscaler.

4. Payload returned to the user:

The Kubernetes system is trying to scale a StatefulSet named fake-deployment using the HorizontalPodAutoscaler, but it cannot find the StatefulSet. The solution is to verify that the StatefulSet name is spelled correctly and exists in the same namespace as the HorizontalPodAutoscaler.

Note: Anonymization does not currently apply to events.

Further Details

Anonymization does not currently apply to events.

In a few analysers like Pod, we feed to the AI backend the event messages which are not known beforehand thus we are not masking them for the time being.

• The following is the list of analysers in which data is being masked:-

  • Statefulset
  • Service
  • PodDisruptionBudget
  • Node
  • NetworkPolicy
  • Ingress
  • HPA
  • Deployment
  • Cronjob

• The following is the list of analysers in which data is not being masked:-

  • RepicaSet
  • PersistentVolumeClaim
  • Pod
  • Log
  • *Events

*Note:

• k8gpt will not mask the above analysers because they do not send any identifying information except Events analyser.

• Masking for Events analyzer is scheduled in the near future as seen in this issue. Further research has to be made to understand the patterns and be able to mask the sensitive parts of an event like pod name, namespace etc.

• The following is the list of fields which are not being masked:-

  • Describe
  • ObjectStatus
  • Replicas
  • ContainerStatus
  • *Event Message
  • ReplicaStatus
  • Count (Pod)

*Note:

• It is quite possible the payload of the event message might have something like "super-secret-project-pod-X crashed" which we don't currently redact (scheduled in the near future as seen in this issue).

Proceed with care

• The K8gpt team recommends using an entirely different backend (a local model) in critical production environments. By using a local model, you can rest assured that everything stays within your DMZ, and nothing is leaked.
• If there is any uncertainty about the possibility of sending data to a public LLM (open AI, Azure AI) and it poses a risk to business-critical operations, then, in such cases, the use of public LLM should be avoided based on personal assessment and the jurisdiction of risks involved.

k8sgpt stores config data in the $XDG_CONFIG_HOME/k8sgpt/k8sgpt.yaml file. The data is stored in plain text, including your OpenAI key.

Config file locations:

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>
  • Minio Configuration with HTTP endpoint k8sgpt cache add s3 --bucket <name> --endpoint <http://localhost:9000>
  • Minio Configuration with HTTPs endpoint, skipping TLS verification k8sgpt cache add s3 --bucket <name> --endpoint <https://localhost:9000> --insecure
    • 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

Listing cache items

k8sgpt cache list

Purging an object from the cache Note: purging an object using this command will delete upstream files, so it requires appropriate permissions.

k8sgpt cache purge $OBJECT_NAME

Removing the remote cache Note: this will not delete the upstream S3 bucket or Azure storage container

k8sgpt cache remove

There may be scenarios where you wish to write your own analyzer in a language of your choice. K8sGPT now supports the ability to do so by abiding by the schema and serving the analyzer for consumption. To do so, define the analyzer within the K8sGPT configuration and it will add it into the scanning process. In addition to this you will need to enable the following flag on analysis:

k8sgpt analyze --custom-analysis

Here is an example local host analyzer in Rust When this is run on localhost:8080 the K8sGPT config can pick it up with the following additions:

custom_analyzers:
  - name: host-analyzer
    connection:
      url: localhost
      port: 8080

This now gives the ability to pass through hostOS information ( from this analyzer example ) to K8sGPT to use as context with normal analysis.

See the docs on how to write a custom analyzer

Listing custom analyzers configured

Adding custom analyzer without install

k8sgpt custom-analyzer add --name my-custom-analyzer --port 8085

Removing custom analyzer
