CLI tool for Hashicorp Vault

This tools allows simple interactions with the vault API, allowing configuration to be done in a separate step using a YAML configuration file.

This is especially interesting if you interact with Hashicorp Vault from automated deployment tools

Installation

The tool is packaged but the package is not yet available on pypi.

pip install vault-cli

If you wish to use the hvac backend, install with

pip install vault-cli[hvac]

Authentication

There are three ways to authenticate against the vault:

• Username and password file: provide a username and a file to read the password from. The file may be - for stdin.
• Certificate: provide the path to a certificate file. The file may also be read from stdin via -.
• Token: Bypass authentication step if you already have a valid token.

Examples

# Connect to https://vault.mydomain:8200/project and list the secrets
$ vault --url=https://vault.mydomain:8200 --certificate=/etc/vault/certificate.key --base-path=project/ list
['mysecret']

# Using the configuration file, get the value for my_secret (yaml format)
$ vault get my_secret
--- qwerty
...

# Same with only the value of the secret in plain text
$ vault get my_secret --text
qwerty

# Add another secret
$ vault set my_other_secret supersecret
Done

# Add a secret object
$ vault set --yaml blob_secret "{code: supercode}"
Done

# Get all values from the vault in a single command (yaml format)
$ vault get-all
---
my_secret: qwerty
my_other_secret: supersecret
blob_secret:
  code: supercode
test:
  my_folder_secret: sesame

# Get a nested secret based on a path
$ vault get-all test/my_folder_secret
test:
  my_folder_secret: sesame

# Get all values from a folder in a single command (yaml format)
$ vault get-all test my_secret
---
my_secret: qwerty
test:
  my_folder_secret: sesame

# Delete a secret
$ vault delete my_other_secret
Done

Configuration

All files at the following location are read (in increasing priority order), parsed, merged and used:

1. /etc/vault.yml
2. ~/.vault.yml
3. ./.vault.yml

Any option passed as command line flag will be used over the corresponding option in the documentation.

The expected format of the configuration is a mapping, with option names and their corresponding values:

---
username: my_username
password-file: ~/.vault-password
# or
token-file: ~/.vault-token
url: https://vault.mydomain:8200
verify: no
base-path: project/
...

Just note that the --verify / --no-verify flag become verify: yes or verify: no

State

The tool is currently in beta mode. It's missing docs, tests, CI, and such. Be warned.
