Consider configuring Structured Logs for Cloud Run

[yuri-sergiichuk]

Cloud Run provides logs gathered from the System.out and System.err out of the box, but the logs are treated by the Stackdriver as plain text messages.

In order to improve the debug and maintenance capabilities, we need to configure Structured logging. The structured (JSON) logs are ingested by the Stackdriving giving us better filtering and searching functionality. E.g. one can find logs by the severity level or for some specific logger using the structured logging.
