Configuring Tarmac with BoltDB

This page contains BoltDB specific configuration to utilize BoltDB with Tarmac.

Tarmac supports multiple configuration sources such as Environment Variables, JSON files, or using HashiCorp Consul. All of these configuration options can also exist together to provide both static and dynamic configurations.

When using Environment Variables, all configurations are prefixed with APP_. The list below will show both Environment and Consul/JSON format for configuration.

Environment Variable	Consul/JSON	Type	Description
APP_BOLTDB_FILENAME	boltdb_filename	string	The full path and filename of the BoltDB file. If the file does not exist, it will be created.
APP_BOLTDB_BUCKET	boltdb_bucket	string	The name of the BoltDB bucket to use. If the bucket does not exist, it will be created.
APP_BOLTDB_PERMISSIONS	boltdb_permissions	int	The permissions to use when creating the BoltDB file. This is an octal value.
APP_BOLTDB_TIMEOUT	boltdb_timeout	int	The timeout in seconds to wait for BoltDB to open.

Consul Format

When using Consul the consul_keys_prefix should be the path to a key with a JSON string as the value. For example, a key of tarmac/config will have a value of {"from_consul":true}.
