install VMOD basic-auth for Varnish - varnish

Question

Im trying to install the VMOD called basicauth.
This is the repo: https://git.gnu.org.ua/vmod-basicauth.git
There is also a README file which is supposed to help guide you through the process.
It tells you to pull the code, also pull code of varnish (did that with help of sudo apt-get source varnish )... I did that, so far so good.
But then Im supposed to do this:
run:
./configure --with-varnish-source=/usr/src/varnish-3.0.1 --with-vmod-dir
THE PROBLEM
I have been trying to figure out where to find that "configure" script. I have no idea where to find it.
When I look at other tutorials, like this one I guess that it should within the vmod-basicauth folder... but it is not. There is only configure.ac. It tried running that file, but that does not work. Does anyone of you know how I can install this VMOD? Any tips or help would be appreciated.
Also: it seems there is only information off very old tutorials and repos... any idea where I could some more up to date infos?
UPDATE
I have also downloaded "The Varnish Book" now, checked on how to isntall "libvmod-example." Within that folder there is a "autogen.sh" file that create the "configure" file. But I also cannot find a any "autogen.sh" in the basicauth package...
Hahha ..... arrrrrrr Im getting nowhere.
Does anyone know where I can find a good tutorial?
Im wokring with ubuntu-server currently. Noticed that redhad has VMODs in their repos, but that won't help me ;)
SYSTEM INFO

Answer 1

I just tested it, and I didn't experience any problems compiling the VMOD.
Here's a step-by-step guide on how to install it.
1. Get a recent Varnish version
I'm not sure whether or not you installed Varnish through the Ubuntu packages, but I advise you to install it via the official packages: https://packagecloud.io/varnishcache/.
2. Install the build dependencies
Install the required build dependencies by using the following command:
apt-get install -y varnish-dev autoconf automake gcc libtool make python3-docutils git
Most of these dependencies are trivial, but there's one specific package that might not be found unless you're using the official Varnish package repo. It's varnish-dev.
I've tried looking for it natively in the Ubuntu Focal repository, and the closest I came was libvarnishapi-dev, but that didn't really work.
That's why I advise using the official packages from https://packagecloud.io/varnishcache/. The version I prefer is https://packagecloud.io/varnishcache/varnish60lts, because it's the LTS version.
3. Get the source code
Once you've put all the dependencies in place, you can go ahead and download the VMOD source code by running the following commands:
cd /usr/src/
git clone git://git.gnu.org.ua/vmod-basicauth.git
As you can see the code will be place in the /usr/src directory.
4. Compile the code
Now that the source code is on your system, you run the following commands to configure, compile and install the VMOD code:
./bootstrap
./configure
make
make install
If ./configure cannot be found, it means it wasn't properly generated by the ./bootstrap command. If that happens, have a look at the output of your ./bootstrap command to figure out what went wrong.
5. Import the VMOD
The VMOD has been installed in the proper location, so it's time to import it into your VCL file and use its features.
Here's a VCL example:
vcl 4.1;
import basicauth;
sub vcl_recv {
if (!basicauth.match("/var/www/.htpasswd",req.http.Authorization)) {
return(synth(401,"Authentication required"));
}
}
