This setups a Hashicorp Vault Cluster in server mode with raft backend storage.
This is entierly unsecure and does not use TLS. Its primary puprose is to easily play with and familiarise with the vault interfaces. It is not an excersie in securtiy, though that may come.
Don't connect this to anything you remotely care about.
##Usage
Bring up the cluster with docker compose up
Set the vault address
export VAULT_ADDR="http://localhost"
initialise the vault cluster
vault operator init
then you can unlock with either the CLI or browse to http://localhost
