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/ calledDockerTelegramChatBot` where I have the Dockerfile.
DockerTelegramChatbot I have two files the
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
