Ask HN: Go libraries for managing Docker container pools and executing commands?

3 points

a year ago

I’m developing a system in Go that maintains a fixed pool of Docker containers (e.g., 10) running a specific image (like ‘node’), where each container remains alive (using a command like tail -f) to be ready for executing arbitrary commands via docker exec. The system tracks the workload of each container, distributes commands to the least loaded one, and monitors container health to automatically restart or replace unhealthy instances.

I’m aware of the official Docker Go SDK (github.com/docker/docker/client) for managing containers, but I’m curious if there are any higher-level tools or libraries in Go that provide additional support for scheduling, load balancing, or enhanced health monitoring of containers in such a setup. Has anyone built or used libraries that streamline this kind of container orchestration and command execution?

Any insights, recommendations, or experiences would be greatly appreciated!
