Installation

To build a Varnish image, choose either the CentOS Stream or RHEL based image:

• RHEL based image

  These images are available in the Red Hat Container Catalog. To download it run:

  $ podman pull registry.redhat.io/rhel8/varnish-6
  

  To build a RHEL based Varnish image, you need to run the build on a properly subscribed RHEL machine.

  $ git clone --recursive https://github.com/sclorg/varnish-container.git
  $ cd varnish-container
  $ git submodule update --init
  $ make build TARGET=rhel8 VERSIONS=6
  

• CentOS Stream based image

  This image is available on Quay.io. To download it run:

  $ podman pull quay.io/sclorg/varnish-6-c9s
  

  To build a CentOS Varnish image from scratch run:

  $ git clone --recursive https://github.com/sclorg/varnish-container.git
  $ cd varnish-container
  $ git submodule update --init
  $ make build TARGET=c9s VERSIONS=6
  
  

• Fedora based image

  You need to build the Fedora variant locally:

  $ git clone --recursive https://github.com/sclorg/varnish-container.git
  $ cd varnish-container
  $ git submodule update --init
  $ make build TARGET=fedora VERSIONS=7
  

Note: while the installation steps are calling podman, you can replace any such calls by docker with the same arguments.

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all provided versions of Varnish.

Contributing

In this repository distgen is used for generating image source files. If you'd like update a Dockerfile, please make changes in specs/multispec.yml and/or Dockerfile.template (or other distgen file) and run make generate.

Usage

For information about usage of Dockerfile for Varnish 6, see usage documentation.

For information about usage of Dockerfile for Varnish 7, see usage documentation.

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Varnish application built on top of the Varnish image.

Users can choose between testing a Varnish test application based on a RHEL or CentOS image.

• RHEL based image

  To test a RHEL8 based Varnish image, you need to run the test on a properly subscribed RHEL machine.

  $ cd varnish-container
  $ git submodule update --init
  $ make test TARGET=rhel8 VERSIONS=6
  

• CentOS Stream based image

   $ cd varnish-container
   $ git submodule update --init
   $ make test TARGET=c9s VERSIONS=6
  

• Fedora based image

  $ cd varnish-container
  $ git submodule update --init
  $ make test TARGET=fedora VERSIONS=7
  

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all provided versions of Varnish.
