# Environment variables

> How a QUEUEBOX_ environment variable maps to a configuration key, which source wins, and the variable of every key.

This page describes how a `QUEUEBOX_` environment variable sets a configuration key, and lists the variable of every key.
The [configuration](/reference/configuration/) page gives the type, the default and the meaning of each key.

## Precedence

QueueBox reads three sources. For each key, the first source in this list that sets the key wins.

1. The `QUEUEBOX_` environment variables.
2. The YAML file that `QUEUEBOX_CONFIG_FILE` names. When the variable is absent, QueueBox reads `/etc/queuebox/queuebox.yml`.
3. The `queuebox.yml` resource in the image.

Source 2 and source 3 do not merge. When the file exists, QueueBox does not read the resource.
When the file is absent and any `QUEUEBOX_` variable is set, QueueBox does not read the resource either.
A deployment that uses variables only therefore gets no source, destination or route from the image.

`QUEUEBOX_CONFIG_FILE` is not a configuration key. It only names the file.

A variable merges with the file key by key inside a map.
`QUEUEBOX_DESTINATIONS_ORDERS_TIMEOUTMS` changes the timeout of the `orders` destination, and the other keys of that destination stay as the file sets them.
A list does not merge. A variable that sets one element of a list replaces the whole list of the file.
Set every key of every element, or set the list in the file only.

When no source holds a configuration, the start fails. The error names the three sources.

## Naming rule

`EnvConfigLoader.envKeyToYamlPath` turns a variable name into a key path:

1. It removes the `QUEUEBOX_` prefix.
2. It turns a double underscore `__` into a literal `_`.
3. It turns every other `_` into a `.` between two levels.
4. It writes the path in lower case. The loader matches a key name in any letter case.

The leaf name therefore has no underscore inside it. `outbox.pollIntervalMs` is `QUEUEBOX_OUTBOX_POLLINTERVALMS`.
A variable that ends in `OUTBOX_POLL_INTERVAL_MS` sets the path `outbox.poll.interval.ms`, which does not exist. QueueBox reports no error for it, and the value has no effect.

| Part of the path | How to write it | Example variable | Key |
| --- | --- | --- | --- |
| A level | One `_` | `QUEUEBOX_DATABASE_URL` | `database.url` |
| A camel case name | The name in upper case, with no `_` | `QUEUEBOX_SERVER_HTTPPORT` | `server.httpPort` |
| A map key | The key in upper case | `QUEUEBOX_SOURCES_STRIPE_PATH` | `sources.stripe.path` |
| A `_` inside a map key | `__` | `QUEUEBOX_DESTINATIONS_MY__API_BASEURL` | `destinations.my_api.baseUrl` |
| A list index | The number | `QUEUEBOX_ROUTES_0_TOPICPATTERN` | `routes[0].topicPattern` |
| A list of values | One index per value | `QUEUEBOX_SOURCES_ORDERS_TOPICS_0` | `sources.orders.topics[0]` |

A map key that a variable sets is always lower case. A variable cannot set a map key that holds a `-` in most shells.
Give a destination or a source a lower case name without `-` when a variable must reach it.

Every validation error prints the variable name of the key, through `EnvConfigLoader.yamlPathToEnvKey`.

## Example

This set of variables configures one HTTP destination, one route and one HTTP source, with no file.

```bash
QUEUEBOX_DATABASE_URL=jdbc:postgresql://db:5432/queuebox
QUEUEBOX_DATABASE_USERNAME=queuebox
QUEUEBOX_DATABASE_PASSWORD=secret
QUEUEBOX_DESTINATIONS_WEBHOOK_TYPE=http
QUEUEBOX_DESTINATIONS_WEBHOOK_BASEURL=https://api.example.com
QUEUEBOX_ROUTES_0_TOPICPATTERN=order.*
QUEUEBOX_ROUTES_0_DESTINATION=webhook
QUEUEBOX_SOURCES_STRIPE_TYPE=http
QUEUEBOX_SOURCES_STRIPE_PATH=/stripe
QUEUEBOX_SOURCES_STRIPE_IDEMPOTENCYKEYPATH=$.id
QUEUEBOX_SOURCES_STRIPE_EVENTTYPEPATH=$.type
```

A header filter uses list indexes at two levels:

```bash
QUEUEBOX_SOURCES_ORDERS_FILTER_REQUIRE_0_HEADER=x-region
QUEUEBOX_SOURCES_ORDERS_FILTER_REQUIRE_0_IN_0=eu
QUEUEBOX_SOURCES_ORDERS_FILTER_REQUIRE_0_IN_1=uk
QUEUEBOX_SOURCES_ORDERS_FILTER_EXCLUDE_0_HEADER=x-test
QUEUEBOX_SOURCES_ORDERS_FILTER_EXCLUDE_0_EXISTS=true
```

The three database variables are the minimum. Every other key has a default or is optional.

## Every variable

The tables use `orders` as the map key of a destination or a source, and `0` as a list index.
Replace them with your own name and index.
A key of a destination or a source applies only to the kinds that the [configuration](/reference/configuration/) page lists for it.
