i2biz/varnish repository overview

⁠Varnish Docker container

A clone of million12/docker-varnish

Notable changes:

• Pass VCL config's contents as an env variable instead of pushing config to volume
• Namespaced all varibles with VARNISH_

⁠Usage

To use this container, you will need to provide your custom config.vcl (which is usually the case).

docker run -d \
  --link web-app:backend-host \
  --volumes-from web-app \
  --env 'VARNISH_ACL_CONFIG=[[base64 encoded vcl file contents]]' \
  million12/varnish

In the above example we assume that:

• You have your application running inside web-app container and web server there is running on port 80 (although you don't need to expose that port, as we use --link and varnish will connect directly to it)
• web-app container has /data volume with varnish.vcl somewhere there
• web-app is aliased inside varnish container as backend-host
• Your varnish.vcl should contain at least backend definition like this:

backend default {
    .host = "backend-host";
    .port = "80";
}

⁠Environmental variables

You can configure Varnish daemon by following env variables:

• VARNISH_ACL_CONFIG base64 encoded config file
• VARNISH_CACHE_SIZE 64m
• VARNISH_VARNISHD_PARAMS -p default_ttl=3600 -p default_grace=3600
