Build

1. Install Go
2. Download ksops source code
3. Build ksops

   cd <project_directory>
   go build ./cmd/ksops
   # executable `ksops` produced!

Example usage

1. Start mozilla/sops and listen on Unix domain sockets at /tmp/sops.sock:

   sops keyservice \
     --network unix \
     --address "/tmp/sops.sock"

2. Start ksops and listen on Unix domain sockets at /tmp/ksops.sock:
   Here we configure ksops to use the PGP key for encryption/decryption. Actually mozilla/sops is doing the work, ksops only forwards the encrypt/decrypt request with the proper credentials.

   ./ksops \
     --pgp.key="FBC7B9E2A4F9289AC0C1D4843D16CEE4A27381B4" \
     "unix:/tmp/ksops.sock" \
     "unix:/tmp/sops.sock"

3. Setup Kubernetes to use a KMS provider (ksops) for data encryption/decryption
