  1. How to build a docker image ?

    • from a dockerfile in the same directory and the image with name testing and version v1.3.0
    docker build -t testing:v1.3.0 .
    • from a dockerfile in the specified path and build the docker image in this directory:
    docker build -t testing:v1.3.0 -f docker/Dockerfile .

  2. How to run docker container and open its terminal ?

    docker run -it busybox sh

  3. Example 1:

    FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY requirements.txt /code
RUN pip install -r requirements.txt
COPY . /code
CMD python run.py

  4. If you are dockerizing a flask script, change the host ip addres from "192.1.0.0" to "0.0.0.0".

    app.run(host="0.0.0.0", port=5000, debug=os.environ.get("debug")=='1')

    here we also give port address and take debug variable from environment

  5. If you dockerize flask, when you run the command expose the flask port to outside computer.

    docker run -p 5000:5000 -e DEBUG=1 flask_app_dev

# -e DEBUG gives the environment variable DEBUG a value of 1

  6. How to stop a container ?

    docker stop 838456456

    stops the docker container with the given id

  7. How to look at the logs in the container ?

    docker logs container_id
#or
docker logs container_name

  8. How to create a container with a name given by you ?

    docker run --name kelbecer redis:latest

  9. How to open a running container's shell ?

    docker exec -it container_id /bin/bash

  10. What is the difference between docker run and docker start ?

    --> docker run creates a container from an image

    --> docker start is for starting a container, that is already created

  11. What is docker network and how to create a docker network ?

    # Docker network allows two containers inside a dockerfile to connect with each other
docker network create mongo-network

# this will create a docker network named mongo-network

  12. To create a mongo container with environmental variables and also connect it to a network:

    docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network mongo

# here:
# -e  is used to give environmental variables
# --net is used to connect to a network

  13. How to remove a docker image ?

    docker rmi image_id

  14. How to start a docker-compose from a file ?

    docker-compose -f docker-compose.override.yml up

  15. How to debug in docker-compose ?

    1. add stdin_open:true and tty:true inside the service
    services:
  autocorrect:
    stdin_open: true
    tty: true
    command:
    1. start the docker-compose:
    docker compose -f test.yml up
    1. Call the started container:
    docker attach container_id

  16. How to assign the port of the container to the local machine ?

    docker run -p 3000:3000 test_image
docker build -t gcr.io/bghntr-speech-recognition/testing .
docker push gcr.io/bghntr-speech-recognition/testing
