Common error messages

Some common error messages and their potential causes are listed in the Flux documentation. For example, the error message “Error syncing: unable to connect to API server” may indicate network connectivity issues or incorrect Kubernetes configuration. (Flux Error Handling)

Logging

Flux logs can be viewed using various tools, such as the Kubernetes kubectl command or the Flux web UI. According to the Flux documentation, “Logs can provide valuable information for troubleshooting and debugging issues.” (Flux Logging)

Enabling and viewing logs
