+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+contact@k8sgpt.ai.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+version 2.0, available at

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+* Currently, the default AI provider is OpenAI, you will need to generate an API key from [OpenAI](https://openai.com)
+  * You can do this by running `k8sgpt generate` to open a browser link to generate it
+* Run `k8sgpt auth add` to set it in k8sgpt.
+  * You can provide the password directly using the `--password` flag.
+* Run `k8sgpt filters` to manage the active filters used by the analyzer. By default, all filters are executed during analysis.
 * Run `k8sgpt analyze` to run a scan.
 * And use `k8sgpt analyze --explain` to get a more detailed explanation of the issues.

+* You also run `k8sgpt analyze --with-doc` (with or without the explain flag) to get the official documentation from Kubernetes.
 
 ## Analyzers
 
-K8sGPT uses analyzers to triage and diagnose issues in your cluster. It has a set of analyzers that are built in, but you will be able to write your own analyzers.

+<details>
+<summary> Using filters </summary>
 
-The the kubectl-ai [project](https://github.com/sozercan/kubectl-ai) uses AI to create manifests and apply them to the cluster. It is not what we are trying to do here, it is focusing on writing YAML manifests.
+_List filters_
 
-K8sgpt is focused on triaging and diagnosing issues in your cluster. It is a tool for SRE, Platform & DevOps engineers to help them understand what is going on in their cluster. Cutting through the noise of logs and multiple tools to find the root cause of an issue.

+
+## LLM AI Backends
+
+K8sGPT uses the chosen LLM, generative AI provider when you want to explain the analysis results using --explain flag e.g. `k8sgpt analyze --explain`. You can use `--backend` flag to specify a configured provider (it's `openai` by default).
+
+You can list available providers using `k8sgpt auth list`:
+
+```
+Default: 
+> openai
+Active: 
+Unused: 
+> openai
+> localai
+> azureopenai
+> cohere
+> amazonbedrock
+> amazonsagemaker
+> google
+> huggingface
+> noopai
+> googlevertexai
+```
+
+For detailed documentation on how to configure and use each provider see [here](https://docs.k8sgpt.ai/reference/providers/backend/).
+
+_To set a new default provider_
+
+```
+k8sgpt auth default -p azureopenai
+Default provider set to azureopenai
+```
+
+## Key Features
+
+<details>
+
+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.
+
+<summary> Anonymization </summary>
+
+1. Error reported during analysis:
+```bash
+Error: HorizontalPodAutoscaler uses StatefulSet/fake-deployment as ScaleTargetRef which does not exist.
+```
+
+2. Payload sent to the AI backend:
+```bash
+Error: HorizontalPodAutoscaler uses StatefulSet/tGLcCRcHa1Ce5Rs as ScaleTargetRef which does not exist.
+```
+
+3. Payload returned by the AI:
+```bash
+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:
+```bash
+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
+  - **_*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](https://github.com/k8sgpt-ai/k8sgpt/issues/560). _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](https://github.com/k8sgpt-ai/k8sgpt/issues/560))_.
+
+### 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.

+There may be scenarios where caching remotely is preferred.
+In these scenarios K8sGPT supports AWS S3 or Azure Blob storage Integration.
+
+<summary> Remote caching </summary>  
+<em>Note: You can only configure and use only one remote cache at a time</em>
+
+_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](https://learn.microsoft.com/en-us/azure/developer/go/azure-sdk-authentication?tabs=bash#2-authenticate-with-azure) 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
+```
+</details>
+
+<details>
+<summary> Custom Analyzers</summary>
+
+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](https://github.com/k8sgpt-ai/schemas/blob/main/protobuf/schema/v1/analyzer.proto) 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](https://github.com/k8sgpt-ai/host-analyzer)
+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_
