Minimal SquidGuard docker image with integrated filter lists based on rootlogin/squid.
This image is meant for blocking unwanted content in a private or corporate network. The blocklists are contained in the docker image, so you have to rebuild it yourself and create a child-image to modify the block settings. It uses the shallalist. If you want to integrate this image in a commercial solution you have to ask them for a license.
Default blocked categories are:
- adv: Advertisments
- aggressive: Aggressive content
- porn: Pornografic content
- spyware: Sites with spyware
- violence: Sites with violence
- warez: Illegal content like warez and keygens.
To see other available categories see: http://www.shallalist.de/categories.html.
It's recommended that you use host networking when running squid, so that you can see the source IP in the logs. Otherwise you will see the IP of your docker host.
docker run --net=host --name=myproxy rootlogin/squidguard
Default blocking is by redirecting the proxy user to duckduckgo.com. To customize this, set the REDIRECT_URL environment variable:
docker run --net=host --name=myproxy -e "REDIRECT_URL=http://myblockpage.com" rootlogin/squidguard
To use this proxy, configure your environment or operating system correctly:
export http_proxy=http://PROXY_HOST:3128 export https_proxy=http://PROXY_HOST:3128
Port 3128 is default.
- /cache: Here goes the squid cache
- /logs: Here goes the squid logs
If you want to configure things like authentication, you should overwrite the default squid configuration. You can do this either by using the volume function of docker, or by creating a child image. You should use the included configuration as base.
docker run --net=host --name=myproxy -v ./mysquid.conf:/etc/squid/squid.conf rootlogin/squidguard
FROM rootlogin/squidguard COPY mysquid.conf /etc/squid/squid.conf
For modifying the block lists the best way is to use a child-image.
Create a new Dockerfile:
FROM rootlogin/squidguard ARG BLOCKED_CATEGORIES=adv,spyware,violence,warez RUN /create-blocklist.sh
docker build -t myproxy_image . and
docker run --net=host --name=myproxy myproxy_image
