# Environment variables

There are a bunch of environment variables that must be set up in order for the instance to run properly.

```properties
LICENSE_KEY

HOST

REDIS_URL

POSTGRES_HOST
POSTGRES_USER
POSTGRES_PORT
POSTGRES_DB
POSTGRES_PASSWD

AUTH0_CLIENTID
AUTH0_DOMAIN
AUTH0_AUDIENCE

MAILGUN_API_KEY
MAILGUN_DOMAIN


```

Let's go through these variables in detail.

#### License Key

The license key to use with this docker container. The container will exit if it is not able to contact <https://taskforce.sh> and validate the license.

You will find your license key on your Taskforce.sh [account](https://taskforce.sh/account/enterprise).

#### Host

This variable should point to the actual host running the dashboard, for example: <https://my.taskforce.dashboard.com>

#### Redis

The dashboard uses Redis for some internal communication and for the Monitoring and Alerts system. A small instance of about 128Mb RAM will be enough in most cases.

#### PostgreSQL

There are a few variables used to configure the required postgres database, just fill in the values for your database provider accordingly. You won't need a powerful PostgreSQL instance for the dashboard, any minimal instance will do.

#### Auth0

The authentication of the users is performed by Auth0. If you are not using Auth0 you can just create a free account which will most likely be enough for your needs. There are some steps involved in configuring Auth0 properly, please refer to this [guide](https://docs.taskforce.sh/on-premises/aws/configure-your-instance/configure-auth0).

#### Mailgun

Mailgun is used for sending alert messages as well as team invitations. You can get a Mailgun account with generous quotas for free, then just follow these [instructions](https://docs.taskforce.sh/on-premises/aws/configure-your-instance/configure-mailgun).

{% hint style="info" %}
Currently the dashboard will be exposed at port **9876,** and cannot be configured to a different port.
