## envs
Includes environment variables in the context of the container instance.
#### Usage:
```js
envs: {
ENV_NAME_1: 'ENV_VALUE_1',
ENV_NAME_2: 'ENV_VALUE_2',
...,
ENV_NAME_N: 'ENV_VALUE_N',
}
```
##### Examples:
We can expose some variables to set up a [Postgres][postgres] database, for example:
```js
envs: {
POSTGRESQL_USER: "admin",
POSTGRESQL_PASS: "password",
POSTGRESQL_DB : "awesome_db",
POSTGRESQL_HOST: "#{net.host}",
POSTGRESQL_PORT: "#{net.port.data}",
}
```
> __Important__: This is not the recommended way to expose sensitive information such as passwords. It is recommended that each developer uses a .env file in the root of the project and that this file is ignored in version control.
