Configure SOPS

SOPS is used for encrypting secrets, e.g. credentials for various systems

Install

https://github.com/getsops/sops

Note:

• MacOS: If desired, one can also use brew to install sops: brew install sops; although this is not officially maintained, the formula is essentially the same as the official installation instructions

Usage

Decrypt and Display Secrets in Terminal:

GPG_TTY=$(tty) sops secrets.yaml

Note: The GPG_TTY is necessary to have the password prompt appear. src: https://www.varokas.com/secrets-in-code-with-mozilla-sops/

Note: secrets.yaml is just an example; the file can have any name

Example

The steps in the following example can be run locally in order to:

• create a sample secrets file
• encrypt the file
• decrypt the file

If these steps work, sops is configured correctly - on your machine ;-)

#!/usr/bin/env bash
set -ueo pipefail
# demo: create a file with a mock secret, src: https://bash-org-archive.com/?244321
# PREREQUISITE: valid sops config, i.e. .sops.yaml
yq -n '.demo.credentials.secret = "hunter2"' > secrets.yaml
# encrypt
sops -e -i secrets.yaml

# decript, print to console
sops -d secrets.yaml
