Question 1

Is APM better than systemd for managing Go apps?

Accepted Answer

APM is tailored for Go with features like automatic compilation from source, while systemd is a general-purpose init system with broader OS integration. For Go-specific workflows, APM offers simplicity, but systemd provides more robustness and ecosystem support for production systems, including better logging and service management.

Question 2

How do I set up APM to run my Go application as a daemon?

Accepted Answer

First, install APM via 'go get github.com/topfreegames/apm', then start the server with 'apm serve'. Use 'apm bin app-name --source="github.com/yourproject"' to compile and daemonize your app. The README provides step-by-step commands, and you can manage it with stop/restart/delete as needed.

Question 3

Does APM support logging for managed processes?

Accepted Answer

The README does not mention built-in logging features; APM focuses on process lifecycle management. For logging, you would need to handle it within your Go application or use external tools like log rotation services, which might require additional configuration.

Question 4

Can I use APM with Docker or Kubernetes?

Accepted Answer

APM is designed for direct process management on a host and is not integrated with container orchestration. For containerized environments, tools like Docker or Kubernetes native process management are more suitable, as APM does not support container-specific features or scalability needs.

Question 5

What happens if the APM server crashes?

Accepted Answer

APM saves process states to disk with 'apm save', allowing restoration via 'apm resurrect'. However, if the server crashes, managed processes might continue running, but control is lost until the server is restarted, requiring manual recovery in some cases.

Question 6

How does APM handle application updates or new versions?

Accepted Answer

APM can restart applications, but for updates, you likely need to re-run 'apm bin' with the new source or use 'apm restart'. The README doesn't specify automated update mechanisms, so manual intervention is required for version changes, which can be cumbersome.
