docker-varnishd

A Docker container for running Varnish Reverse Proxy

This container can be used to run a varnishd reverse proxy instance. The container can be used as-is, or extended to customize configuration, versions, etc.

This container is based on the CentOS 7 Docker image, and uses YUM for package management. The Varnishd software package is installed from the EPEL repository.

Building

docker build . --build-arg VERSION=4.0.5 -t varnishd

Usage

To run the container using the default settings and VCL:

docker run -p 80:80 limit0/varnishd

To customize the Varnish configuration (VCL), either extend this image and ADD your configuration, or mount the /etc/varnish directory and override the default.vcl. *Note: You will also have to specify the secret and varnish.params if volume mounting -- see the default examples in the /etc folder of this repository.

Logging

varnishd does not log requests to stdout/stderr, but rather uses its own varnishlog application to access logs from the running process. You can easily access varnish logs by including the name parameter when running the container, and running a second process to view the logs using varnishlog.

docker run -p 80:80 --name varnishd limit0/varnishd
docker exec -it varnishd varnishlog

You can utilize the same named container access method to use other varnish administrative and logging tools, such as varnishadm, varnishhist, varnishncsa, varnishstat, varnishtop, varnishlog, varnish_reload_vcl, or varnishtest.
