Docker + Boto3 + Python + Vector Seems not finding boto3

[satscreate]

I've been trying to add some python libs to vector image as i wanted to run python scripts via vector file.
But getting below error,
"ImportError: No module named boto3"

DockerFile:

FROM timberio/vector:0.22.2-debian
RUN apt update && apt install --assume-yes \
    python \
    python3-pip
VOLUME [/var/lib/vector/]
RUN pip install boto3
RUN vector --version # buildkit
ENTRYPOINT ["/usr/bin/vector"]

Built command:
docker build -t vector/custom .

Compose.yaml

services:
  vector:
    image: vector/custom
    command: -c /vector.yaml
.....

vector.yaml calls a python script:

sources:
  exec:
    type: exec
    command: ["bash", "-c", "python test.py"]
.....

test.py:

import json
import os
import io
import time
import gzip
import boto3
boto3.resource(....)
....

When i deploy above stack i am always getting below error, any idea?

{"command":["bash","-c","python /test.py"],"host":"54353535","message":"    import boto3","pid":33,"source_type":"exec","stream":"stderr"}
{"command":["bash","-c","python /test.py"],"host":"54353535","message":"ImportError: No module named boto3","pid":33,"source_type":"exec","stream":"stderr"}

Hi @satscreate !

You are installing boto3 via pip3 which is Python 3, but python is Python 2. I ran your apt commands in the container and then:

root@e1ac7af04c1c:/# pip --version
pip 20.3.4 from /usr/lib/python3/dist-packages/pip (python 3.9)
root@e1ac7af04c1c:/# python --version
Python 2.7.18

I believe you want to install the python-is-python3 package so that python is python3.

Thanks @jszwedko . It works like charm now. Python version mismatch.
