I'm trying to figure out how to prevent synchronization issues between CI and CD when using a GitOps workflow with FluxCD. Here's the scenario: I push changes to my GitLab repository, triggering a docker build and push that takes about 5 minutes. However, FluxCD checks my repo every minute for changes, which means it could trigger a deployment before the docker image is fully built and available. Is there a way to configure FluxCD to avoid this race condition? Should I manually specify the image hash in FluxCD to ensure the correct version is deployed?

It sounds like your CI/CD pipeline might need some tweaking. You should build your artifacts and push your images to the registry before updating the image tag for your pod. A lot of folks have run into similar issues, so why not check out existing pipelines for inspiration? I found this book that covers CI/CD with Docker and Kubernetes—it might have some useful insights!
That's a good point! GitOps is about having the image tag properly bumped by tools like FluxCD's Image Automation Controller. Just make sure you avoid using `:latest` for your images to dodge race conditions.
