Simple Vault introduction

Today a tiny introduction to Vault from HashiCorp. I will just show the simplest usage. But this will help to get a first idea of Vault and the features.

Requirements

Preparation

Start Vault Server

Copy Root Token value to clipboard!!!

Insomnia

Create new environment “vault” under “Manage Environments” and store here your URL as “base_url” and Root Token as “api_key”.

Now we create 4 simple requests

insomnia requests

for all requests we add Header

For first URL (POST: Add new secret) we use “{{ base_url }}/secret/MyFirstSecret” and we add following body as JSON.

After send the key:value is stored inside Vault. You can modify the request (e.q. “{{ base_url }}/secret/MySecondSecret”) and send some more.

Our next request is to show all keys (GET: Get list of secret keys) “{{ base_url }}/secret?list=true”. The Preview will show similar output.

3rd request is to get the value from a specific key (GET: Get value of specific secret) “{{ base_url }}/secret/MySecret”.

Last request is for delete (DEL: Delete specific secret) “{{ base_url }}/secret/MySecret”.

Tipp: if you lost the root token (Vault server is running) you can find the value!
