What about officially providing a Docker image?

Provided we have a Dockerfile file like this:

FROM alpine:3.14

RUN \
    apk -U add py3-pip && \
    rm -rf /var/cache/apk/* && \
    ln -s /usr/bin/python3 /usr/bin/python && \
    wget -O - https://codeload.github.com/aboul3la/Sublist3r/tar.gz/refs/heads/master | tar xz -C /tmp && \
    mv /tmp/Sublist3r-* /etc/sublist3r && \
    pip config set global.cache-dir false && \
    pip install -r /etc/sublist3r/requirements.txt && \
    ln -s /etc/sublist3r/sublist3r.py /usr/local/bin/sublist3r

ENTRYPOINT ["sublist3r"]

We could:

create an image tagged as sublist3r with
```
$ docker build --tag sublist3r .
```

run sublist3r simply with

$ docker run --rm sublist3r --help
usage: sublist3r [-h] -d DOMAIN [-b [BRUTEFORCE]] [-p PORTS] [-v [VERBOSE]] [-t THREADS] [-e ENGINES] [-o OUTPUT] [-n]

OPTIONS:
 -h, --help            show this help message and exit
 -d DOMAIN, --domain DOMAIN
                       Domain name to enumerate it's subdomains
 -b [BRUTEFORCE], --bruteforce [BRUTEFORCE]
                       Enable the subbrute bruteforce module
 -p PORTS, --ports PORTS
                       Scan the found subdomains against specified tcp ports
 -v [VERBOSE], --verbose [VERBOSE]
                       Enable Verbosity and display results in realtime
 -t THREADS, --threads THREADS
                       Number of threads to use for subbrute bruteforce
 -e ENGINES, --engines ENGINES
                       Specify a comma-separated list of search engines
 -o OUTPUT, --output OUTPUT
                       Save the results to text file
 -n, --no-color        Output without color

Example: python /usr/local/bin/sublist3r -d google.com
