Thank you for your contribution. Can you explain why you introduced the Openbao component?

I introduced Openbao because it's a free fork of the Vault by Hashicorp, and I wanted to store my secret on a vault, instead of having them in etcd in clear text.

Vault is already supported by ApiSix, I've just chosen the free fork

hello, I can't reproduce this issue, can you please answer these questions first ?

is this an error you see in docker logs?

Do you see the openbao container, in the ouput of the command docker ps?
