Cross-platform provider for Summon that talks to keyrings.

Wraps the Python keyring library to allow summon to fetch credentials from:

• OSX Keychain
• Linux Secret Service
• Windows Credential Vault
• gnome-keyring
• kwallet

To use this provider, you will need to install:

• Summon
• Python and pip
• The Python keyring library.
  • Note: v21+ of this library requires Python 3.6+.

To install the Python keyring library, run:

$ pip install keyring

Install the keyring provider by cloning the repo and creating a symlink in the /usr/local/lib/summon directory.

You may need to run the following commands as a super user.

$ git clone [email protected]:cyberark/summon-keyring.git
$ cd summon-keyring
$ mkdir -p /usr/local/lib/summon
$ ln -s "$PWD/ring.py" /usr/local/lib/summon/keyring.py

Note: If you copy the ring.py file to /usr/local/lib/summon/ instead of symbolically linking it, you may see an error like:

Traceback (most recent call last):
  File "/usr/local/lib/summon/ring.py", line 22, in <module>
    value = keyring.get_password(
AttributeError: module 'keyring' has no attribute 'get_password'

This can be resolved by creating a symbolic link instead.

To use this provider, invoke Summon as usual. If you have multiple providers installed, be sure to provide the path to the keyring provider using the --provider flag:

summon --provider keyring.py \
  --yaml 'MY_ENV_VAR: !var secret/path' \
  my_command

By default, this provider fetches secrets from the service summon. To retrieve secrets from another service, set the SUMMON_KEYRING_SERVICE environment variable.

Let's use the OSX keychain to store a secret and fetch it with summon.

First, we add the secret:

$ security add-generic-password -s "summon" -a "secret/path" -w "secretvalue"

Note: You can also add a secret to the OSX keychain through the Keychain Access utility. The "Keychain Item Name" field should be summon, the "Account Name" should be the secret path, and the "Password" field should contain the secret value. If you are using other secret stores, you can also use the keyring command utility installed with the keyring Python package to set the secret:

$ keyring set summon secret/path # enter "secretvalue" when prompted

Once the secret has been added, we can fetch it with summon by using this provider.

$ summon --provider keyring.py \
  --yaml 'MYSECRET: !var secret/path' \
  printenv MYSECRET

secretvalue

Using summon, you can easily switch between this keyring provider for development and use and more appropriate provider, like Conjur, in production.
