Docker logging and logging drivers
Docker not only changed how applications are deployed but also the workflow for log management. Instead of writing logs to files, containers write logs to the console (stdout/stderr). Docker then uses a logging driver to export container logs to chosen destinations.
Container log management
Log management is an essential function within Docker, like any application. But, due to the transient nature of Docker workloads, it becomes more critical as we lose the filesystem and potentially logs as well when the container is deleted or faces any issue. So, we should use log drivers to export the logs into a particular place and store and persist it. If you have a log analytics solution, the best place for your logs to be is within it. Docker supports multiple log targets via logging drivers. Let's have a look.
Logging drivers
As of the time of writing this book, the following logging drivers are available:
