Varnish Docker Image

Container runs varnish with a prometheus exporter for metrication and will provide varnishcsa as it's containers log output for ingestion into your cluster log viewer.

Notes

This varnish image differs from stock in a few key ways:

• Supports prometheus exporter
• Configured to allow large headers to enable Surrogate cache tags to be easily cleared:

  -p http_resp_hdr_len=16k
  

Use

You usually want to mount VCL configuration into /etc/varnish to use:

volumeMounts:
          - name: "config"
            mountPath: "/etc/varnish/default.vcl"
            subPath: "default.vcl"
