Add ARM64 Support for Docker Image to Enable Raspberry Pi 5 Compatibility

[pimushkin]

Problem:
The application could not run in a Docker container on my Raspberry Pi 5 because the Docker image was only built for the amd64 architecture. Since the Raspberry Pi 5 uses an ARM64 processor, it requires a Docker image built for the linux/arm64 architecture.

Solution:
Updated the GitHub Actions workflow (docker-publish.yml) to include ARM64 support by specifying both linux/amd64 and linux/arm64 platforms in the platforms parameter of the Build and push Docker image step. This ensures that Docker images are built and published for both architectures.

Changes Made:

• Modified the docker-publish.yml file:
  • Added platforms: linux/amd64,linux/arm64 under the with section of the Build and push Docker image step.

Testing:

• Built and ran the updated Docker image on my Raspberry Pi 5.
• Confirmed that the application starts and functions correctly within the Docker container on the ARM64 architecture.

Notes:

• No changes were required in the Dockerfile since the base image ubuntu supports multiple architectures, including ARM64.
• This change does not affect existing amd64 builds and maintains backward compatibility.

Conclusion:
By adding ARM64 support, we expand the compatibility of our application to run on devices like the Raspberry Pi 5, making it accessible to a broader range of users.
