Extra Config

The Extra Config feature enables you to define additional routes and middlewares in separate .yml or .yaml files, stored in a specified directory.

This approach helps streamline the management of routes and middlewares, especially as configurations grow in size.

When managing many routes and middlewares in a single file, it can become cumbersome.

By using the Extra Config feature, you can split configurations into smaller, more manageable files, making them easier to maintain.

Example Configuration

To define extra routes, specify the configuration in the gateway section as shown below:

version: 2
gateway:
  ...
  ## Add additional configuration
  extraConfig:
    # Directory containing additional configuration files.
    directory: /etc/goma/extra
    watch: false  # Set to true to watch for changes in the directory.
  routes:
    - path: /
      name: example

Routes Configuration

You can create additional route configurations by placing them in files with a .yaml or .yml extension inside the /etc/goma/extra directory.

Here’s an example of a route configuration file:

routes:
  - path: /order
    name: order-service
    hosts: []
    rewrite: /
    methods:
      - GET
      - PUT
    backends:
      - endpoint: https://api.example.com  # Backend server URL
      - endpoint: https://api2.example.com   # Backend server URL
      - endpoint: https://api3.example.com   # Backend server URL
    healthCheck:
      path: /
      interval: 30s
      timeout: 10s
      healthyStatuses:
        - 200
        - 404
    cors:
      origins: []
      headers: {}
    disableHostForwarding: true
    blockCommonExploits: false
    middlewares:
      - auth-middleware  # List of middlewares for this route.
  - path: /cart
    name: cart-service
    hosts: []
    rewrite: /
    methods:
      - GET
      - PUT
      - POST
    destination: http://cart-service:8080
    healthCheck:
      path: /
      interval: 30s
      timeout: 10s
      healthyStatuses:
        - 200
        - 404
    cors:
      origins: []
      headers: {}
    rateLimit: 60
    disableHostForwarding: true
    blockCommonExploits: false
    middlewares:
      - auth-middleware  # List of middlewares for this route.

Extra Middlewares

Similarly to routes, you can define middlewares in separate files stored in the /etc/goma/extra directory. These middlewares can be applied globally or to specific routes.

##### Extra Middlewares
middlewares:
  # Basic Authentication middleware.
  - name: extra-basic-auth
    type: basic  # Authentication type (options: basic, jwt, OAuth).
    paths:
      - /user
      - /admin/*
      - /account
    rule:
      realm: your-realm # Optional
      users:
        - admin:{SHA}0DPiKuNIrrVmD8IUCuw1hQxNqZc= # SHA-1 hash
        - admin:$2a$12$LaPhf23UoCGepWqDO0IUPOttStnndA5V8w7XPNeP0vn712N5Uyali # bcrypt hash
        - admin:admin # Plaintext password
      # username: admin # Deprecated
      # password: admin # Deprecated

  # Access control middleware to block specific paths.
  - name: extra-api-forbidden-paths
    type: access
    paths:  # Paths to block.
