Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

The changes introduce a GitHub Actions workflow and a Dockerfile to automate the build and push process for a Solana validator image, accommodating both amd64 and arm64 architectures. This automation is necessary to streamline the deployment and testing of Solana validators, particularly to support environments that require arm64 compatibility, such as Apple's M1/M2 chips and AWS Graviton instances.

What

• .github/workflows/sol-validator-build-push.yaml:
  • Added a new GitHub Actions workflow to build and push Solana validator images for both amd64 and arm64 architectures.
  • Configured workflow triggers and environment variables.
  • Included steps for checking out the code, configuring AWS credentials, logging into Amazon ECR, setting up Docker Buildx, downloading CCIP artifacts, and building and pushing the Docker images.
• images/solana-validator/Dockerfile:
  • Created a new Dockerfile to build a Solana validator image from the agave source.
  • Defined base and builder stages to install dependencies, build the Solana validator and solana binaries, and prepare the final image.
• images/solana-validator/README.md:
  • Added a README file explaining the purpose of the custom Solana validator image and its support for both amd64 and arm64 architectures.
  • Highlighted the necessity for arm64 support for compatibility with recent hardware and cloud instances.

JFYI @smickovskid , I think it's no longer needed and we switched priorities, but feel free to reopen if needed.
