JSON logging format.

[foal]

Hi,

Is it possible to switch the logging format of Kubeapps to JSON?

Best,
Stas.

Hi @foal, I don't think there is, as of today, a direct way to enable structured JSON logs as the default output in Kubeapps. We are using klog as the logging library (but not in every file, though, see #3848). I guess a good starting point is the migration guide the k8s folks wrote: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/migration-to-structured-logging.md
Alternatively, you can use a solution like Logstash for parsing the log entries.

If you suggest any specific approach for implementing structured logs, please feel free to send a PR!

We can (and should) update in the kubeapps apisserver to using klog.InfoS and klog.ErrorS which are drop-in replacements, then users can choose to add the --logging-format option to the deployment (or better, we enable from the chart). At least that would have us enabling structured logging in the main service into the future.

For the record, we have standardized the logging libraries we were using (#3848 ) and we've created an issue for working on the structured log as Michael suggested: #4193

If you want to start migrating those log traces more important to your use case, please feel free to contribute :)
