I just started going through the tutorial and trying to wrap up some of my codes into the docker. The question might sound familiar to many of you as I can see quite similar threat but unfortunately I couldn’t get my heads around so decided to write it here.
I have made a telegram chatbot using python. All files are under /project/ . I have another folder under /project/ called DockerTelegramChatBot` where I have the Dockerfile.
Inside the DockerTelegramChatbot I have two files the Dockerfile and requirements.txt.
The content of the Dockerfile looks like the following
# Use an official Python runtime as a parent image
FROM python:3.6-stretch
# Set the working directory to /app
WORKDIR /app
# Copy the current directory contents into the container at /app
COPY . /app
ADD . .
# Install any needed packages specified in requirements.txt
RUN pip install -r requirements.txt --default-timeout=100
# Make port 80 available to the world outside this container
EXPOSE 80
# Run app.py when the container launches
CMD pwd
CMD ls
CMD python /app/main_bot.py
I build the image using
docker build -t simpletelegramchatbot DockerTelegramChatBot/
and run it with
docker run -p 4000:80 simpletelegramchatbot
The main question is how I can resolve the “No such file or directory after building the image”. But also, I wonder what is the best practice to troubleshoot such cases, if I edit the dockerfile, do I have to build it from scratch every time ? “pip install requirements” takes a few minutes and makes the whole process quite annoying.
I appreciate your assistance
