"/app/node_modules/electron/dist/electron exited with signal SIGTRAP" electron app docker

I'm trying to run an electron app in docker. I have created the docker image successfully using the command "docker build. -t pi/electron-app-node16", when I try to run the docker image (docker run pi/electron-app-nod16) getting this error "/app/node_modules/electron/dist/electron exited with signal SIGTRAP"

Python creates Folder inside docker image but remove when processing completes

Python Program does create folder and put some files over there. But when i try to run the program inside docker via CMD
It creates the folder and put files over there and upon completion, the folder somehow gets removed or doesnt show inside the docker image.
I have tried the following things:
Check Folder Exist after creating - It shows folder created over there.
Check inside the docker image using bash - It doesnt show the folder and contents.
The dockerfile is
FROM ubuntu:18.04

Changes to filesystem are not stored in docker image. They exist in container created from an image but if you use 'docker run' command a new container is created.

cant open .env/activate in docker compose but work in docker build

Following is my docker file
FROM ubuntu:18.04

It works when built using docker build .
Docker-compose file

services:
pythonscripts:
build: .
volumes:

But when i try with docker-compose using docker-compose up. it gives following error:

How to set the path for python for docker installing from image ubuntu

I made the image from ubuntu:18.04 and install python.
However when I did this in docker-compose
command: python manage.py runserver
it shows the path error.
Maybe I didn't set the path??
but how I set the path for docker user??
ERROR: for django Cannot start service django: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"python\": executable file not found in $PATH": unknown
ERROR: Encountered errors while bringing up the project.

ADD ./src /code/

You can solve this in two ways (works for me):
in docker-compose add:
command: bash -c 'python manage.py runserver'
or you can add CMD command in your Dockerfile:
CMD: python manage.py runserver

TesseractNotFoundError: two docker container python app (docker-compose)

I have my python project with tesseract running locally, and it works in Pycharm.
I used docker-compose.yml, having two containers (app and t4re) as follows:
version: '3'
services:
app:
build: .
image: ocr_app:latest
depends_on:
- tesseract
tesseract:
image: tesseractshadow/tesseract4re
container_name: t4re
and my Dockerfile is as follows:
FROM python:3.6.1
# Create app directory
WORKDIR /app
# Bundle app source
COPY venv/src ./src
COPY venv/data ./data
# Install app dependencies
RUN pip install -r src/requirements.txt
CMD python src/ocr.py
and I keep getting these errors:
FileNotFoundError: [Errno 2] No such file or directory: 'tesseract'
pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path
I am new to docker and read tons of documents, but I still cannot manage to fix this error. I've read the following answers. I guess I have to link tesseract to the python app with an environment variable, but I do not know how.
Use Tesseract 4 - Docker Container from uwsgi-nginx-flask-docker
TesseractNotFoundError: tesseract is not installed or it's not in your path

You need to install tesseract in your docker image before using it. By default python:3.6.1 image does not have tesseract in it. You need to take ubuntu base image install tesseract and python in it then continue your work.
Here is the docker file for the solution:
FROM ubuntu:18.04
RUN apt-get --fix-missing update && apt-get --fix-broken install && apt-get install -y poppler-utils && apt-get install -y tesseract-ocr && \
apt-get install -y libtesseract-dev && apt-get install -y libleptonica-dev && ldconfig && apt-get install -y python3.6 && \
apt-get install -y python3-pip && apt install -y libsm6 libxext6
Please adjust the python version as per your requirement.

I had this issue on one of my projects that runs on Docker (a Ubuntu container).
To solve that, I had to:
- install pytesseract via requirements.txt; so it your requirements.txt should contain:
pytesseract
- you have to install tesseract-ocr. To do that, you have to include the following lines in your dockerfile:
FROM ubuntu:18.04
ENV PYTHONUNBUFFERED 1
RUN apt-get update && apt-get install -y software-properties-common && add-apt-repository -y ppa:alex-p/tesseract-ocr
RUN apt-get update && apt-get install -y tesseract-ocr-all
RUN apt-get install -y python3-pip python3-minimal libsm6 libxext6
# To make sure that tesseract-ocr is installed, uncomment the following line.
# RUN tesseract --version
