Try Vault with MySQL storage backend (via Docker)

Initialise (will return keys and a token)

curl -X PUT http://0.0.0.0:8200/v1/sys/init --data '{"secret_shares":1, "secret_threshold":1}'

Use one of the keys to unseal

curl -X PUT http://0.0.0.0:8200/v1/sys/unseal --data '{"key":"a5e665962f544dd16471c120c5500a7906cfbaeb3f18ae0fc6c5c71d444f0a90"}'

Use the root token to store something
