@abhibhaw, I have added the CLI steps. Please note the devtron-cli repo is a private one and is inaccessible to public. Let's connect once to discuss how to make the configuration steps (in this doc) useful to our audience.

[gitguardian]

⚠️ GitGuardian has uncovered 2 secrets following the scan of your pull request.

Please consider investigating the findings and remediating the incidents. Failure to do so may lead to compromising the associated services or software components.

🔎 Detected hardcoded secrets in your pull request

GitGuardian id	GitGuardian status	Secret	Commit	Filename
10220829	Triggered	Generic High Entropy Secret	0d9f1d2	charts/devtron/values.yaml	View secret
10220829	Triggered	Generic High Entropy Secret	0d9f1d2	charts/devtron/devtron-bom.yaml	View secret

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
