Starting interactive terminal in a Python image container

Question

I downloaded an image public.ecr.aws/lambda/python:3.6 from this link and I am trying to open an interactive terminal into this container image.

I tried the following tree approaches and none of these opens up any interactive terminal:

docker run -it public.ecr.aws/lambda/python:3.6 bash
docker run -it public.ecr.aws/lambda/python:3.6 /bin/bash
docker run -it public.ecr.aws/lambda/python:3.6 sh

This is the output I get in all the above three commands, it seems to be displaying the container logs rather than opening up an interactive terminal within the container image

INFO[0000] exec '/var/runtime/bootstrap' (cwd=/var/task, handler=)

Please help

Nope, not tried yet. I don't need to execute any python commands actually, I need to install a few unix executables and hence looking for an interactive terminal — user182944

@user182944 That is not how you do that. You create your own Dockerfile which is build upon public.ecr.aws/lambda/python:3.6 and then in your Dockerfile you install the software that you need and run this image. — Jens

Agreed, but some packages that I need are breaking and hence its easier to open an interactive terminal and try it out manually, then will convert it into a working Dockerfile — user182944

ok, here's the answer 1 year and 3 months late ;-) but hopefully will be useful for someone.

docker run -it --rm --entrypoint /bin/bash public.ecr.aws/lambda/python:3.9

You just need to overwrite entrypoint, which was set to a shell script in the base image:

The image is not designed for interactive use. Once you have built an image with an actual lambda, call it with the name of that lambda as the first argument.
