There are many methods for writing Vault policies. 

This gist was created to collect the most common methods 
such that they can be easily used as references for syntax, 
as well as evaluation for which method suits a particular purpose.

TODO:

- Add complex policy examples
- Add @json.file examples

Take a consul snapshot:

consul snapshot save backup.snap

Verify consul snapshot:

consul snapshot inspect backup.snap

Stop Consul

systemctl stop consul.service

Stop Vault

#!/bin/bash

## The following command starts Vault in development mode
## specifiying a root token value of 'root'
##
# VAULT_UI=true vault server -dev -dev-root-token-id="root"

## Login with root token
## Good for demo mode, should only be used on production cluster
## during initial configuration

#!/bin/bash

# start vault
VAULT_UI=true vault server -dev -dev-root-token-id=root -dev-listen-address=127.0.0.1:8200

# login as root - DO NOT DO THIS IN PRODUCTION
vault login root

# write some secrets
vault kv put secret/test color=blue number=eleventeen
