Instalation

Vault is a single binary. To install in a linux system there is two options

  1. Use the repository (for example in Ubuntu, more here) 
     curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
 sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
 sudo apt-get update && sudo apt-get install vault

  2. Dowload the binary, unzip it and move it to the path.

    Afterwards use this command to test it:

     vault --help

dev mode

Vault server can be initated in -dev mode Is not secure but allows to interact locally with vault

To run it

vault server -dev
...
vault status

Afterwards, in order to run a client, the following environment variables and data should be present

export VAULT_ADDR='http://127.0.0.1:8200'
export VAULT_TOKEN="s.aG0eAygkOQB7pITOH9xF5uln"
Unseal Key: vvP1DiOAjUoxDS4lm+bvFKewbAOieB3B1R6g6nEdzRU=

In the -dev mode, vault gives this data in a non secure manner.

  • $VAULT_ADDR is used by the CLI to determine to which instance of vault to connect
  • $VAULT_TOKEN is need to authenticate the CLI to vault. By setting it as env variable, there is no need for vault login

UI

Running on -dev mode, an UI is exposed at port 8200
