Proxy purge requests to multiple varnish servers

Works with AWS or GCE.

You can also specify host and port to listen on:

./varnish-purge-proxy aws --listen=127.0.0.1 --port=8000

You can also specify the destination port to target:

./varnish-purge-proxy aws --destport=6081

varnish-purge-proxy will cache the IP lookup for 60 seconds, you can change this as follows:

./varnish-purge-proxy aws --cache=120

Specify tags to limit instances that receive the purge request, multiple tags can be used. You must specify at least one tag.

./varnish-purge-proxy aws Service:varnish Environment:live

AWS access key and secret key can be added as environment variables, using either AWS_ACCESS_KEY_ID or AWS_SECRET_ACCESS_KEY. If these are not available then IAM credentials for the instance will be checked.

Specify an instance name prefix to limit instances that receive the purge request with the --nameprefix argument.

varnish-purge-proxy gce --credentials=creds.json --region=us-central1 --project=my-project --nameprefix=varnish

GCE credentials should be provided using the --credentials argument.

Build a binary by running:
