Environment Variables

This page documents all environment variables recognised by Photosphere.

AWS / S3 Variables

When no S3 credentials are present in databases.json, Photosphere reads AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, and AWS_ENDPOINT directly from process.env to construct S3 credentials.

Variable	Description	Example
AWS_ACCESS_KEY_ID	S3 access key ID	AKIAIOSFODNN7EXAMPLE
AWS_SECRET_ACCESS_KEY	S3 secret access key	wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
AWS_REGION	S3 region	us-east-1
AWS_ENDPOINT	S3 endpoint URL (for non-AWS S3-compatible services)	https://nyc3.digitaloceanspaces.com

Other Variables

Variable	Description	Default
GOOGLE_API_KEY	Google API key for reverse geocoding	None
PSI_ENCRYPTION_KEY	Encryption key for encrypted storage (fallback if not passed via -k flag or databases.json)	None
PHOTOSPHERE_VAULT_TYPE	Selects the vault backend: keychain (OS keychain) or plaintext (JSON files on disk)	keychain
PHOTOSPHERE_VAULT_DIR	Overrides the vault directory path (only used with the plaintext backend)	~/.config/photosphere/vault/
PHOTOSPHERE_CONFIG_DIR	Overrides the Photosphere config directory	~/.config/photosphere/
