This is a squid2 + apache2 box to replace all images on any website with a bunch of funny effects. I have used it on April Fools' Day at my workplace.
I have built a 4-node CoreOS cluster + a load balancer in front of them (see haproxy.cfg), but you can scale it as you want.
- rewrite.pl: upside-down, wave, monochromize, etc.
- ascii.pl: turn images into ASCII art
- tourette.pl: convert images to animgif with blinking phrases
- watermark.pl: insert the face picture of my boss to all images
##Demo
I have set up a transparent proxy in the office, so everyone's traffic went through my proxy cluster.
Basically, you just have to set up a NAT redirection from LAN -> *:80 to proxymachine:8080.
It depends on your environment, you can find easily a lot of howtos on the Internet.
If you want to use the load balancer, just pull a basic haproxy image and bind mount the config file to the container and that's it!
I have used 4 CoreOS nodes so I can scale it up easily, as we have a lot of coworkers with a high web traffic.
I used PXE booted CoreOS with a basic pxe-cloud-config.yml with custom services, you can see the service definitions in the repo as well.
From pushing the power button to have an operating proxy, it takes about 2-3 minutes. Automagically!
The docker container can be downloaded from the official Docker Hub: https://registry.hub.docker.com/u/dmegyesi/aprilfoolsproxy/
docker pull dmegyesi/aprilfoolsproxy
To start the service, listening on docker_host_machine:8080:
docker run --name aprilfoolsproxy -d -i -t -p 8080:3128 dmegyesi/aprilfoolsproxy
docker build -t dmegyesi/aprilfoolsproxy .
- modify the
url_rewrite_programparameter in/etc/squid/squid.conf
- please note the container doesn't have vim or other editors; however, you can use sed, see Dockerfile for reference
- reload/restart squid process
The default script is rewrite.pl.
