@ -19,4 +19,59 @@ on every path, use `vault help` after mounting the backend.
## Quick Start
TODO
The first step to using the mysql backend is to mount it.
Unlike the `generic` backend, the `consul` backend is not mounted by default.
```
$ vault mount consul
Successfully mounted 'consul' at 'consul'!
```
Next, we must configure Vault to know how to contact Consul.
This is done by writing the access information:
```
$ vault write consul/config/access address=127.0.0.1:8500 token=root
Success! Data written to: consul/config/access
```
In this case, we've configured Vault to connect to Consul
on the default port with the loopback address. We've also provided
an ACL token to use with the `token` parameter. Vault must have a management
type token so that it can create and revoke ACL tokens.
The next step is to configure a role. A role is a logical name that maps
to a policy used to generated those credentials. For example, lets create
a "readonly" role:
```
POLICY='key "" { policy = "read" }'
$ echo $POLICY | base64 | vault write consul/policy/readonly policy=-
Success! Data written to: consul/policy/readonly
```
The backend expects the policy to be base64 encoded, so we need to encode
it properly before writing. The policy language is documented by Consul,
but we've definited a root read-only policy.
To generate a new set Consul ACL token, we simply read from that role:
```
$ vault read consul/readonly
Key Value
lease_id consul/readonly/c7a3bd77-e9af-cfc4-9cba-377f0ef10e6c
lease_duration 3600
token 973a31ea-1ec4-c2de-0f63-623f477c2510
```
Here we can see that Vault has generated a new Consul ACL token for us.
We can test this token out, and verify that it is read-only:
```
$ curl 127.0.0.1:8500/v1/kv/foo?token=973a31ea-1ec4-c2de-0f63-623f477c25100
[{"CreateIndex":12,"ModifyIndex":53,"LockIndex":4,"Key":"foo","Flags":3304740253564472344,"Value":"YmF6"}]
$ curl -X PUT -d 'test' 127.0.0.1:8500/v1/kv/foo?token=973a31ea-1ec4-c2de-0f63-623f477c2510
