SOPS Encryption
Encrypt secrets in configuration files while keeping structure visible.
When to Use This Skill
Use this skill when:
- Encrypting secrets in Git
- Implementing GitOps with secrets
- Managing Kubernetes secrets as code
- Encrypting configuration files
Prerequisites
- SOPS installed
- KMS access (AWS, GCP, Azure) or PGP key
Installation
bash
# macOS
brew install sops
# Linux
wget https://github.com/getsops/sops/releases/download/v3.8.0/sops-v3.8.0.linux.amd64
chmod +x sops-v3.8.0.linux.amd64
mv sops-v3.8.0.linux.amd64 /usr/local/bin/sopsBasic Usage
bash
# Encrypt with AWS KMS
sops --encrypt --kms arn:aws:kms:region:account:key/key-id secrets.yaml > secrets.enc.yaml
# Decrypt
sops --decrypt secrets.enc.yaml
# Edit encrypted file
sops secrets.enc.yaml
# Encrypt in place
sops --encrypt --in-place secrets.yamlConfiguration
yaml
# .sops.yaml

# With ArgoCD
# Install ksops plugin for ArgoCD to decrypt secretsBest Practices
- Store .sops.yaml in repository
- Use different keys per environment
- Rotate encryption keys regularly
- Never commit unencrypted secrets
- Use key aliases for readability
