# this shows creating a Vault instance running integrated storage/raft, 
# then adding a KV and taking a snapshot
# then kill the raft DB files to simulate a storage failure
# repeat new Vault instance, restore snapshot, unseal and auth with orig keys
# and read some data to show how backup/restore works

# not meant to be a live script to run!
# this uses the vault_config.hcl from https://gist.github.com/mikegreen/c2df5eea2283f0dbc5f3a5d3650536fd

# Test Vault migration from consul to raft.

# Dependencies: vault, consul, nc (netcat)
# Writes to (and blows away) ~/migrate_consul_to_raft.
# Kills any running vault or consul processes.
# Tested on MacOS and Linux.
