In this blog post, I will show you how to build a Docker image using a dockerfile on Linux machine.
We use the docker build command to create a Docker image using a file that contains build instruction. The file that contains the instructions is called Dockerfile.
Let’s create a Dockerfile using the following command.
In the Docker file I will copy the following lines which will build the image.
FROM python RUN mkdir c:\app COPY Password_generator_class.py /app/Password_generator_class.py CMD python /app/Password_generator_class.py
Docker Build Command
The next step is building the image using the following command.
Note: Make sure you run it from the same folder the dockerfile is located.
docker build --tag passwordgenerator .
After the build process is completed, run the following command to check that the image is available.
