aad-pod-identity VS externalsecret-operator

Can someone please help me with a step by step guide to perform this. https://github.com/Azure/aad-pod-identity Blog I am referring: https://trstringer.com/connect-k8s-apps-msi/

Q: So how am I supposed to log in to Azure so that my app can obtain tokens? A: I tell devs: For local development log in to Azure CLI with your normal user account. It has Contributor over your Dev/Test subscription and you can access secrets and configuration from their Dev/Test Key Vaults. For staging and production running in Azure (in our case Docker containers running on AKS) we use User-Assigned Managed Identity and aad-pod-identity project. This managed identity has least-privilege permissions over staging and production environments to do it's job at runtime.

The existing Azure AD Pod Identity project addresses this need. However, the Azure AD workload identity approach is simpler to use and deploy, and overcomes several limitations in Azure AD Pod Identity:

As described on the documentation, azwi is the suggested approach from now on since Azure AD Pod Identity has been (somehow) deprecated as you can read on the github repo and on the blog post here.

Unfortunately, password maintenance and rotation is a chore and has to be done in both places. There are however other things that you might want to try. 1. Kerberos authentication in pure container environments. This is something you can do on any Linux environment that is connected to AD. 2. Use AAD pod identity (https://github.com/Azure/aad-pod-identity) if running from AKS, but it is still in preview.

If you are using an external KMS in any case, then there are other options, such as the kubernetes-external-secrets operator that was originally started by GoDaddy and the externalsecret-operator from Container Solutions. If you use HashiCorp Vault, you also have the option of using the Vault Secrets operator. This works similarly to the Sealed Secrets Operator, but instead of managing its own key material, it retrieves the secrets from Vault. The CNCF Technology Radar from January 2021 provides an overview of the types of tools that are available for secrets management.
