PR Review

⏱️ Estimated effort to review [1-5]	2, because the changes are focused on a single workflow file with a clear purpose, integrating multi-platform support for Docker images. The modifications are straightforward, involving the setup of QEMU, Docker Buildx, and adjusting the Docker login and push steps to use GitHub Actions. The scope is limited, making it easier to review.
🧪 Relevant tests	No
🔍 Possible issues	Missing platform specification: The PR adds support for `linux/amd64` and `linux/arm64` platforms but does not specify handling or checks for platforms that might not be supported by the base images or dependencies. This could lead to build failures or unexpected behavior on unsupported platforms.
🔒 Security concerns	No

Code feedback:

relevant file	.github/workflows/push-image-to-dockerhub.yml
suggestion	Consider adding a failure strategy for the job to manage partial failures gracefully, especially since multi-platform builds can fail on one platform but succeed on another. This can be achieved by adding a `strategy` block with `fail-fast: false` and specifying `max-parallel` to control the number of concurrent jobs. [medium]
relevant line	docker:

relevant file	.github/workflows/push-image-to-dockerhub.yml
suggestion	It's recommended to add a step to cache Docker layers to speed up subsequent builds. This can be done using the `actions/cache` action before the build and push step. This will help in reducing build times and saving bandwidth. [important]
relevant line	- name: Build and push

relevant file	.github/workflows/push-image-to-dockerhub.yml
suggestion	Ensure that the Dockerfile and any scripts it references are compatible with both `amd64` and `arm64` architectures. This might involve checking base images for multi-architecture support or adjusting scripts to be architecture-aware. [important]
relevant line	platforms: linux/amd64,linux/arm64

relevant file	.github/workflows/push-image-to-dockerhub.yml
suggestion	Add a step to verify the successful deployment of images to Docker Hub for both platforms. This could involve pulling the images for each platform and running a basic test to ensure they are correctly built and pushed. [medium]
relevant line	push: true

PR Code Suggestions

Category	Suggestions
Security	Use GitHub Actions environment secrets for DockerHub credentials to enhance security. ___ It's recommended to use GitHub Actions environment secrets instead of repository secrets for sensitive information like DockerHub credentials. This enhances security by scoping access to those who need it. You can define environment secrets in the settings of your GitHub repository under the "Environments" section. [.github/workflows/push-image-to-dockerhub.yml [22-23]](https://github.com/enjin/platform/pull/39/files#diff-375807204432883d2fe0f02e08e633760f5802823833f872fd5e68d8b0939c6fR22-R23) ```diff -username: ${{ secrets.DOCKERHUB_API_USERNAME }} -password: ${{ secrets.DOCKERHUB_API_TOKEN }} +username: ${{ env.DOCKERHUB_API_USERNAME }} +password: ${{ env.DOCKERHUB_API_TOKEN }} ```
Best practice	Use a specific version of Ubuntu runner to ensure predictable behavior. ___ Consider specifying a more specific runner than `ubuntu-latest` for the `runs-on` field. Using a specific version, such as `ubuntu-20.04`, can provide more predictable behavior over time as GitHub updates the `ubuntu-latest` runner. [.github/workflows/push-image-to-dockerhub.yml [11]](https://github.com/enjin/platform/pull/39/files#diff-375807204432883d2fe0f02e08e633760f5802823833f872fd5e68d8b0939c6fR11-R11) ```diff -runs-on: ubuntu-latest +runs-on: ubuntu-20.04 ```
	Add a step to check Docker image build status before pushing to DockerHub for better error handling. ___ For better error handling and debugging, consider adding a step to check the Docker image build status before pushing it to DockerHub. This can be achieved by using the `docker/build-push-action@v5` with `load: true` and `push: false`, followed by a conditional step that pushes the image if the build succeeds. [.github/workflows/push-image-to-dockerhub.yml [25-34]](https://github.com/enjin/platform/pull/39/files#diff-375807204432883d2fe0f02e08e633760f5802823833f872fd5e68d8b0939c6fR25-R34) ```diff -- name: Build and push +- name: Build uses: docker/build-push-action@v5 + with: + context: . + file: configs/core/Dockerfile + platforms: linux/amd64,linux/arm64 + load: true + push: false + tags: enjin/$DOCKER_REPOSITORY:$IMAGE_TAG +- name: Push + if: success() + uses: docker/build-push-action@v5 + with: + context: . + file: configs/core/Dockerfile + platforms: linux/amd64,linux/arm64 + push: true + tags: enjin/$DOCKER_REPOSITORY:$IMAGE_TAG ```
	Add a unique build argument to ensure Docker images are always built fresh. ___ To ensure the Docker image is always fresh and to avoid potential caching issues, consider adding a `build-args` option with a unique value like the current timestamp. This can be particularly useful when you have layers in your Dockerfile that may not change often but you want to ensure they are always up to date. [.github/workflows/push-image-to-dockerhub.yml [25-34]](https://github.com/enjin/platform/pull/39/files#diff-375807204432883d2fe0f02e08e633760f5802823833f872fd5e68d8b0939c6fR25-R34) ```diff - name: Build and push uses: docker/build-push-action@v5 + with: + context: . + file: configs/core/Dockerfile + platforms: linux/amd64,linux/arm64 + push: true + tags: enjin/$DOCKER_REPOSITORY:$IMAGE_TAG + build-args: BUILD_DATE=$(date +%Y-%m-%d:%H:%M:%S) ```
Maintainability	Use environment variables for Docker repository name and image tag to improve readability and avoid typos. ___ To avoid potential typos and enhance readability, consider storing the Docker repository name and image tag as environment variables at the job level, instead of directly embedding them in the `tags` field. [.github/workflows/push-image-to-dockerhub.yml [34]](https://github.com/enjin/platform/pull/39/files#diff-375807204432883d2fe0f02e08e633760f5802823833f872fd5e68d8b0939c6fR34-R34) ```diff -tags: enjin/$DOCKER_REPOSITORY:$IMAGE_TAG +tags: enjin/${{ env.DOCKER_REPOSITORY }}:${{ env.IMAGE_TAG }} ```
