Hi Team,

i’m new to vault and trying to integrate it with kubernetes clusters.
Vault is on a single AWS instance running with consul as storage backend . We are looking to integrate this vault instance with multiple EKS clusters.
In docs i can see to integrate vault we have to install it in kubernetes and provide kubernetes_host for the cluster. then enable kubernetes auth

vault auth enable kubernetes

vault write auth/kubernetes/config \
   token_reviewer_jwt="$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" \
   kubernetes_host=https://${KUBERNETES_PORT_443_TCP_ADDR}:443 \
   kubernetes_ca_cert=@/var/run/secrets/kubernetes.io/serviceaccount/ca.crt

is there a way to provide multiple host or use single instance with multiple clusters?

Thanks.

Hey @shubham.sharma

Thank you for your interest in HashiCorp, always happy to have new members asking questions!

I Just wanted to let you know that you posted your message in the Boundary channel and not to Vault. I would recommend re-posting this to the Vault team here: Vault - HashiCorp Discuss.

If you ever want to give Boundary a try we will happily answer any questions you have, we are currently in a free public beta on HCP.
