Kubernetes

The tricky part of installing this plugin into containerized environments, like Kubernetes, is that a container should contain a database within it.

Warning

Setup below is provided for demonstration purpose and should not be used on production. Traefik's plugin site is observed to be frequently unavailable, so plugin download may fail on pod restart.

Tested with official Traefik chart version 26.0.0.

The following snippet should be added to values.yaml:

experimental:
  plugins:
    geoip2:
      moduleName: github.com/thiagotognoli/traefikgeoip
      version: v0.22.0
deployment:
  additionalVolumes:
    - name: geoip2
      emptyDir: {}
  initContainers:
    - name: download
      image: alpine
      volumeMounts:
        - name: geoip2
          mountPath: /tmp/geoip2
      command:
        - "/bin/sh"
        - "-ce"
        - |
          wget -P /tmp https://raw.githubusercontent.com/thiagotognoli/traefikgeoip/main/geolite2.tgz
          tar --directory /tmp/geoip2 -xvzf /tmp/geolite2.tgz
additionalVolumeMounts:
  - name: geoip2
    mountPath: /geoip2
