I'm relatively new to Docker and have been using it in a development environment for about 8 months. Now, I'm considering deploying a setup in production, but I'm unsure if Docker is necessary for my case. My configuration includes one Kafka server, one database, and around 10 to 15 services running on two Linux machines for redundancy, without any internet access. My question is whether using Docker would simplify deployment and management compared to a traditional setup where I configure each service manually. I've tested everything in development without issues, but I want to ensure this setup is reliable since it will be locked after deployment, ideally for a long period.

I've been running Docker in production for over 5 years. There are both pros and cons, and a lot depends on how you structure your setup. For your simple case, Docker and Docker Compose would work nicely, but ensuring data persists is crucial. Just take the time to test everything thoroughly before going live.
It sounds like a great opportunity to leverage Docker! Since you've had a smooth experience in development, Docker could really simplify your production deployment. Just be mindful that managing changes can be more complex in Docker, so try to prepare for possible future issues by familiarizing yourself with common error analysis in a containerized environment.
I see no reason to shy away from using Docker in your situation. It's been battle-tested in much larger production environments, and many cloud solutions rely on it. As long as you don't push Docker to its limits unnecessarily, it should serve you well.
Using Docker seems perfect for your use case. It streamlines deployments and configuration management, which can be a huge time saver compared to manual setups. Just ensure your environment isn't overly complex since Docker shines best with straightforward setups.
That's reassuring to hear! I was worried about the complexity, but it sounds like sticking to a simple setup will be the key.
Honestly, Docker is a solid choice for a setup like yours. Just keep in mind the importance of data persistence, especially if you're running databases across your two machines. I recommend looking into shared storage solutions to maintain database availability and prevent data loss during failover scenarios.
I appreciate the insight! I'll definitely focus on learning how to troubleshoot potential Docker issues before we lock down the deployment.
