Issue while creating a docker image of Go with nuclei and python

[lijoabraham]

Nuclei version:

2.9.5

Current Behavior:

Getting the below error while creating a docker image of Go with nuclei and python.

'Dockerfile'

# Base image
FROM golang:latest

# Install necessary dependencies
RUN apt-get update && apt-get install -y git

# Install Nuclei
RUN go install -v github.com/projectdiscovery/nuclei/v2/cmd/nuclei@latest

# Install Python
RUN apt-get install -y python3 python3-pip

# Copy your Python script into the container
COPY . .

# Set the working directory
WORKDIR /app

# Run your Python script
CMD ["python3", "/app/nuclei.py"]

and python code 'nuclei.py' is

import subprocess

def run_nuclei(target, template):
    command = f'nuclei -target {target} -ud {template}'
    try:
        output = subprocess.check_output(command, shell=True, text=True, stderr=subprocess.STDOUT)
        return output
    except subprocess.CalledProcessError as e:
        # Handle any errors that occurred during execution
        print(f"Error executing Nuclei: {e.output}")
        return None

# Usage example
target_url = "https://google.com"
template_path = "/app/nuclei-templates"
result = run_nuclei(target_url, template_path)
if result:
    print(result)

Expected Behavior:

docker image should build without giving any error

Steps To Reproduce:

1. Create the above mentioned files.
2. run the command - `docker build -t golang-nuclei-python . '

@lijoabraham can you try to install curl first in the Docker container? We saw similar behavior here: #2875

[lijoabraham]

@olearycrew still same.

Moving this to the discussion as this is not an issue in nuclei and more of a networking issue on the host machine.

Found these issues online with Docker. Some insight on there might help.

@MetzinAround I was able to got it working by using the below docker file commands.

# Base image
FROM projectdiscovery/nuclei:latest

WORKDIR /app
# Install Python
ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools

COPY requirements.txt .
RUN pip3 install --no-cache -r requirements.txt


# Copy your Python script into the container
COPY . /app

# Run your Python script
CMD ["bash"]

Awesome! Thanks for the update.
