Hi everyone, Here's a triplet of announcements that should make life easier for a bunch of vmod users.
# install-vmod Earlier this month I pushed https://github.com/varnish/toolbox/tree/master/install-vmod which, I must admit, takes inspiration from xcir's vmod-packager ( https://github.com/xcir/vmod-packager), but with a way less ambitious scope. Essentially, you can just point install-vmod at a tarball (local or remote), with an optional checksum and it will download, build, test and install the vmod for you: install-vmod https://github.com/varnish/varnish-modules/releases/download/0.20.0/varnish-modules-0.20.0.tar.gz e63d6da8f63a5ce56bc7a5a1dd1a908e4ab0f6a36b5bdc5709dca2aa9c0b474bd8a06491ed3dee23636d335241ced4c7ef017b57413b05792ad382f6306a0b36 It's only a few lines of shell and doesn't handle dependencies installation, but it's pretty convenient for the next point. # install-vmod in official docker images install-vmod is included in all official images, making it very easy to supplement the images with your own vmod combinations. Here's a and example taken from the official docs (https://hub.docker.com/_/varnish): FROM varnish:7.1-alpine # install build dependencies USER root RUN set -e; \ apk add --no-cache $VMOD_DEPS; \ \ # install one, possibly multiple vmods install-vmod https://github.com/varnish/varnish-modules/releases/download/0.20.0/varnish-modules-0.20.0.tar.gz; \ \ # clean up apk del --no-network $VMOD_DEPS USER varnish Note the VMOD_DEPS that allows you to quickly add and remove the general building dependencies. # official docker images now include varnish-modules and vmod_dynamic Now that images have an easy way to install vmods, it seemed like a waste to not install a couple of those, namely: - varnish-modules (https://github.com/varnish/varnish-modules) because it's full of tools that are useful in most setups (headers, var, str, etc.) - vmod_dynamic (https://github.com/nigoroll/libvmod-dynamic) since containers usually live in dynamic environments with backend with a DNS record but no fixed IP And those two have the big benefit of not requiring any extra dependencies compared to Varnish, meaning the image size only slightly increased. And that's it for now! As usual, feedback is welcome, especially since the features are so new. Until next time! -- Guillaume Quintard
