Trying to create a runpod template for the LTX Video trainer,
I used this dockerfile for the image :

FROM pytorch/pytorch:2.2.0-cuda12.1-cudnn8-runtime

RUN apt-get update && apt-get install -y \
    git curl ffmpeg build-essential \
  && rm -rf /var/lib/apt/lists/*

RUN curl -Ls https://astral.sh/uv/install.sh | bash \
  && cp /root/.local/bin/uv /usr/local/bin/uv

WORKDIR /app
RUN git clone https://github.com/Lightricks/LTX-Video-Trainer.git .
RUN uv venv && uv sync

# ← New bits:
COPY start.sh /start.sh
RUN chmod +x /start.sh

ENTRYPOINT ["/start.sh"]

the start.sh file contains this

#!/usr/bin/env bash
set -e

# 1) activate your venv
source /app/.venv/bin/activate

# 2) hand off to bash (keeps the shell open & interactive)
exec /usr/bin/bash

the docker image runs fine locally, but when running a pod with a template (shown in the screenshot) it doesn't work, no way to connect.

What did I miss? this is the first time I try make a RunPod template

you need run command in your start.sh otherwise it will bootloop container

I just want to get inside the container and run bash commands interactively, is that not possible? I thought that's what my start.sh does

but bash -c 'sleep infinity'

that did the trick thank you, now I can't get it work from vscode, my ssh connection doesn't support SCP & SFTP, maybe that's the reason ? I don't know how to make it support those
