v0.2.8

GeoBlock

Simple plugin for Traefik to block or allow requests based on their country of origin. Uses GeoJs.io.

Configuration

It is possible to install the plugin locally or to install it through Traefik Pilot.

Configuration as local plugin

Depending on your setup, the installation steps might differ from the one described here. This example assumes that your Traefik instance runs in a Docker container and uses the official image.

Download the latest release of the plugin and save it to a location the Traefik container can reach. Below is an example of a possible setup. Notice how the plugin source is mapped into the container (/plugin/geoblock:/plugins-local/src/github.com/PascalMinder/geoblock/) via a volume bind mount:

`docker-compose.yml`

version: "3.7"

services:
  traefik:
    image: traefik

    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /docker/config/traefik/traefik.yml:/etc/traefik/traefik.yml
      - /docker/config/traefik/dynamic-configuration.yml:/etc/traefik/dynamic-configuration.yml
      - /docker/config/traefik/plugin/geoblock:/plugins-local/src/github.com/PascalMinder/geoblock/

    ports:
      - "80:80"

  hello:
    image: containous/whoami
    labels:
      - traefik.enable=true
      - traefik.http.routers.hello.entrypoints=http
      - traefik.http.routers.hello.rule=Host(`hello.localhost`)
      - traefik.http.services.hello.loadbalancer.server.port=80
      - traefik.http.routers.hello.middlewares=my-plugin@file

To complete the setup, the Traefik configuration must be extended with the plugin. For this you must create the traefik.yml and the dynamic-configuration.yml` files if not present already.

          countries:
            - CH

Traefik Plugin registry

This procedure will install the plugin via the Traefik Plugin registry.

Add the following to your traefik-config.yml

experimental:
  plugins:
    GeoBlock:
      moduleName: "github.com/PascalMinder/geoblock"
      version: "v0.2.5"

# other stuff you might have in your traefik-config
entryPoints:
  http:
    address: ":80"
  https:
    address: ":443"

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
  file:
    filename: "/etc/traefik/dynamic-configuration.yml"

In your dynamic configuration add the following:

http:
  middlewares:
    my-GeoBlock:
      plugin:
        GeoBlock:
          silentStartUp: false
          allowLocalRequests: true
          logLocalRequests: false
          logAllowedRequests: false
          logApiRequests: false
          api: "https://get.geojs.io/v1/ip/country/{ip}"
          apiTimeoutMs: 500
          cacheSize: 25
          forceMonthlyUpdate: true
          allowUnknownCountries: false
          unknownCountryApiResponse: "nil"
          countries:
            - CH

And some example docker file for traefik:

version: "3"
networks:
  proxy:
    external: true # specifies that this network has been created outside of Compose, raises an error if it doesn’t exist
services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    networks:
      proxy:
        aliases:
          - traefik
    ports:
      - 80:80
      - 443:443
    volumes:
      - "/etc/timezone:/etc/timezone:ro"
      - "/etc/localtime:/etc/localtime:ro"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "/a/docker/config/traefik/data/traefik.yml:/etc/traefik/traefik.yml:ro"
      - "/a/docker/config/traefik/data/dynamic-configuration.yml:/etc/traefik/dynamic-configuration.yml"

This configuration might not work. It's just to give you an idea how to configure it.

Full plugin sample configuration

allowLocalRequests: If set to true, will not block request from Private IP Ranges
logLocalRequests: If set to true, will log every connection from any IP in the private IP range
api: API URI used for querying the country associated with the connecting IP
countries: list of allowed countries
blackListMode: set to false so the plugin is running in whitelist mode

Configuration options

Silent start-up: `silentStartUp`

If set to true, the configuration is not written to the output upon the start-up of the plugin.

Allow local requests: `allowLocalRequests`

If set to true, will not block request from Private IP Ranges.

Log local requests: `logLocalRequests`

If set to true, will show a log message when some one accesses the service over a private ip address.

Log allowed requests `logAllowedRequests`

If set to true, will show a log message with the IP and the country of origin if a request is allowed.

Log API requests `logApiRequests`

If set to true, will show a log message for every API hit.

API `api`

Even if an IP stays in the cache for a period of a month (about 30 x 24 hours), it must be fetch again after a month.

Allow unknown countries `allowUnknownCountries`

Some IP addresses have no country associated with them. If this option is set to true, all IPs with no associated country are also allowed.

The API uri can be customized. This options allows to customize the response string of the API when a IP with no associated country is requested.

When set to true the filter logic is inverted, i.e. requests originating from countries listed in the countries list are blocked. Default: false.

Countries `countries`

A list of country codes from which connections to the service should be allowed. Logic can be inverted by using the blackListMode.

Allowed IP addresses `allowedIPAddresses`

A list of explicitly allowed IP addresses or IP address ranges. IP addresses and ranges added to this list will always be allowed.

allowedIPAddresses:
  - 192.0.2.10          # single IPv4 address
  - 203.0.113.0/24      # IPv4 range in CIDR format  
  - 2001:db8:1234:/48   # IPv6 range in CIDR format
