projectdiscovery/subfinder repository overview

⁠

Subfinder is a subdomain discovery tool that discovers valid subdomains for websites. Designed as a passive framework to be useful for bug bounties and safe for penetration testing.

⁠Running Subfinder in a Docker Container

You can use the official dockerhub image at subfinder⁠. Simply run -

> docker pull projectdiscovery/subfinder

The above command will pull the latest tagged release from the dockerhub repository.

If you want to build the container yourself manually, git clone the repo, then build and run the following commands

• Clone the repo using git clone https://github.com/projectdiscovery/subfinder.git
• Build your docker container

docker build -t projectdiscovery/subfinder .

• After building the container using either way, run the following -

docker run -it projectdiscovery/subfinder

The above command is the same as running -h

For example, this runs the tool against uber.com and output the results to your host file system:

docker run -v $HOME/.config/subfinder:/root/.config/subfinder -it projectdiscovery/subfinder -d uber.com > uber.com.txt
