So sadly we are still on Vault 1.0.3. Yes we need to upgrade. Meanwhile Alex Roman wants to launch Vault agent 1.4 in Kubernetes because of its templating feature. Which makes sense
But I’m concerned about compatibility issues here. Correct me if I’m wrong, but the normal recommended Hashicorp methodology for updating is
a) Update server cluster first
b) Then update Vault clients
Is the reverse tested or supported?
