Configuring Tarmac with Cassandra
This page contains Cassandra specific configuration to utilize Cassandra 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 |
|---|---|---|---|
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}.
