Run GCC Docker image on Raspberry pi

 Steps to Run GCC Docker image on Raspberry pi:

1. Create folder with below contents:

    build --> Folder

    Dockerfile --> Docker image file

    main.c  --> C Program

2. Write a simple c program into main.c file

     // C program to implement

    // the above approach

    #include <stdio.h>

    // Driver code

    int main()

    {

        printf("Welcome to Docker World!!!\n");

        return 0;

    }

3. Edit Dockerfile and write below contents

    FROM gcc:latest

    COPY . /build

    WORKDIR /build/

    RUN gcc -o main main.c

    CMD [“./main”]

4. Save and Build Dockerfile, using command "docker build -t main-gcc-app ."

    DEPRECATED: The legacy builder is deprecated and will be removed in a future release.

                Install the buildx component to build images with BuildKit:
