Is it possible to start Vault dev server on 0.0.0.0 instead of 127.0.0.1?

Question

I have a Hashicorp Vault server running on an AWS EC2 instance at 127.0.0.1:8200.

In my Security Group's inbound rules, I have TCP 8200 enabled. But, I can't access Vault server from my local machine. I think it's because dev server is only available from inside EC2 instance (because it's running at 120.0.0.1, am I right?).

Is it possible to run Vault dev server at 0.0.0.0 instead, so I can access it from Internet?

Answer 1

Start your Vault server with the following command:

vault server -dev -dev-listen-address="0.0.0.0:8200"

You can also specify the address via the VAULT_DEV_LISTEN_ADDRESS environment variable.
