I'm currently using Docker Compose for local development and testing, and I'm looking for the best way to transition my setups to the cloud. My main objective is to keep the development and production environments as similar as possible. Additionally, I'm curious about how to implement high availability in this process. Any suggestions?

Most cloud providers offer CI/CD pipelines that help automate this process. For instance, with GCP, you can trigger workflows from GitHub to deploy your builds to an artifact repository, which is super handy. You can also use Docker Swarm to simplify your deployment using Docker Compose files. Just remember, while Kubernetes is robust and great for HA, Docker Swarm is simpler for basic needs. I even created a GitHub demo for this, feel free to check it out! https://github.com/johnjkenny/dock_schedule
To keep dev and production environments close, ensure they share the same architecture. You can set up a load balancer with multiple hosts running your app, both locally and in production. It may be a bit pricey but definitely worthwhile for consistency.
You should definitely consider using Kubernetes for high availability. It’s designed to manage Docker containers and is great for scaling and load balancing your applications in the cloud.
I’m still puzzled about why we don’t have a straightforward way to run Docker Compose in production that includes automatic load balancing and scaling. Am I missing something here?
Why try to build a Kubernetes solution specifically for Docker Compose when Kubernetes itself is way more flexible and powerful?
I second that! Kubernetes is a robust solution for these needs.
