I've been diving into the complexities of bootstrapping a KMS (Key Management Service) and it's quite a challenge. When setting up a KMS integration meant to automate the population of secrets, there's an awkward starting point that seems to get overlooked. Essentially, the first problem is that to kick off the process, you need a secret to initialize the KMS setup. This secret, however, must come from somewhere else, often requiring you to create it manually or through some hastily written scripts. Since the KMS is being built up from scratch, that secret ends up being unsecured during the initial phase, which is definitely concerning. I've encountered this situation repeatedly, and it feels like a never-ending loop when trying to get secure infrastructure up and running. Regardless of how many tools and automations are in place, that first secret is always left vulnerable while everything else gets configured. How do others navigate this bootstrap phase when establishing new environments with secrets?

Starting with the first secret really feels like a leap of faith. Personally, I recommend using tightly-scoped temporary secrets, such as SSM (AWS Systems Manager) or encrypted files, to handle the initial bootstrap. Just be sure to rotate them quickly afterwards. KMS bootstrapping can feel a bit iffy, so it’s best to have a solid strategy in place.
If you've got cloud services, you might not face this issue directly. For instance, both EKS (Elastic Kubernetes Service) and AKS (Azure Kubernetes Service) support workload identities, which means they can access KMS or Key Vault via IAM without manual bootstrapping. So if you're using these services, External Secrets can manage everything smoothly without needing a bootstrap secret. But I'm curious about your thoughts on this, especially around data population complexity for new environments.
Ah, the classic bootstrap dilemma! I've thought about linking that 'genesis' secret to a company password vault like 1Password, but there’s always that manual intervention required. Someone has to kick off the system to get it going, right? It's just part of the process. How do you handle that when bringing up a new environment?
