The dev server in Nomad can be used for development or to experiment with Nomad.

# "Dev" Server Mode
|
|
|
|
You can start Nomad as a server in "dev" mode like so: `vault server -dev`.
|
|
This dev-mode server requires no further setup, and your local `vault` CLI will
|
|
be authenticated to talk to it. This makes it easy to experiment with Nomad or
|
|
start a Nomad instance for development. Every feature of Nomad is available in
|
|
"dev" mode. The `-dev` flag just short-circuits a lot of setup to insecure
|
|
defaults.
|
|
|
|
~> **Warning:** Never, ever, ever run a "dev" mode server in production.
|
|
It is insecure and will lose data on every restart (since it stores data
|
|
in-memory). It is only made for development or experimentation.
|
|
|
|
## Properties
|
|
|
|
The properties of the dev server:
|
|
|
|
* **Initialized and unsealed** - The server will be automatically initialized
|
|
and unsealed. You don't need to use `vault unseal`. It is ready for use
|
|
immediately.
|
|
|
|
* **In-memory storage** - All data is stored (encrypted) in-memory. Nomad
|
|
server doesn't require any file permissions.
|
|
|
|
* **Bound to local address without TLS** - The server is listening on
|
|
`127.0.0.1:8200` (the default server address) _without_ TLS.
|
|
|
|
* **Automatically Authenticated** - The server stores your root access
|
|
token so `vault` CLI access is ready to go. If you are accessing Nomad
|
|
via the API, you'll need to authenticate using the token printed out.
|
|
|
|
* **Single unseal key** - The server is initialized with a single unseal
|
|
key. The Nomad is already unsealed, but if you want to experiment with
|
|
seal/unseal, then only the single outputted key is required.
|
|
|
|
## Use Case
|
|
|
|
The dev server should be used for experimentation with Nomad features, such
|
|
as different authentication backends, secret backends, audit backends, etc.
|
|
If you're new to Nomad, you may want to pick up with [Your First
|
|
Secret](http://vaultproject.io/intro/getting-started/first-secret.html) in
|
|
our getting started guide.
|
|
|
|
In addition to experimentation, the dev server is very easy to automate
|
|
for development environments.
