Steps to reproduce

import os, subprocess package, but can not be executed. It always report "operation not permitted"

def main(command):
    import os, subprocess
    cmd = command

    try:
        print(cmd)
        output = subprocess.check_output(cmd, stderr=subprocess.STDOUT)
        print("Output:")
        result = output.decode('utf-8')
    except subprocess.CalledProcessError as e:
        result = f"Error executing grpcurl command: {e.output.decode('utf-8')}"

Can not allow to execute some OS command?

✔️ Expected Behavior

The issue you're encountering with executing OS commands using Python's os and subprocess modules in Dify's self-hosted Docker environment is likely due to security restrictions. Dify employs several security measures to prevent unauthorized execution of OS commands:

1. Seccomp Whitelist Policy: This policy allows only specific system calls, which can prevent the execution of certain OS commands ^[1].

2. File System Isolation: The environment is isolated, limiting the ability to execute commands that could affect the host system ^[1].

3. Network Isolation: Separate network configurations further restrict unauthorized access ^[1].

These measures are in place to ensure a secure execution environment. If you need to execute specific commands, you might need to adjust the security settings or explore alternative approaches that comply with these restrictions.

def main() -> dict:
    import os
    hostname = os.popen("hostname")
    aaa = os.read(hostname)

    return {
        "result": hostname,
    }
