# --- Docker Compose Service Configuration ---
# These variables are used by docker-compose.yml to configure the services. Leave them unchanged if you use Docker services for Postgresql, Valkey (Redis) and Meilisearch. If you decide to use your own instances of these services, you can substitute them with your own connection credentials.

# --- Storage Settings ---
# Choose your storage backend. Valid options are 'local' or 's3'.
STORAGE_TYPE=local
# The maximum request body size to accept in bytes including while streaming. The body size can also be specified with a unit suffix for kilobytes (K), megabytes (M), or gigabytes (G). For example, 512K or 1M. Defaults to 512kb. Or the value of  Infinity if you don't want any upload limit.
BODY_SIZE_LIMIT=100M

# --- Local Storage Settings ---
# The path inside the container where files will be stored.
# This is mapped to a Docker volume for persistence.
# This is not an optional variable, it is where the Open Archiver service stores application data. Set this even if you are using S3 storage.
# Make sure the user that runs the Open Archiver service has read and write access to this path.
# Important: It is recommended to create this path manually before installation, otherwise you may face permission and ownership problems.

# --- Storage Encryption ---
# IMPORTANT: Generate a secure, random 32-byte hex string for this key.
# You can use `openssl rand -hex 32` to generate a key.
