Managing Logs with Docker Volumes
Explore how to configure your Go and Gin app to write logs to files and use Docker volumes to persist those logs outside the container. This lesson teaches how to set up structured logging with Zap and mount local directories to container paths, enabling easy access to log files for debugging and maintenance.
We'll cover the following...
So far, we've been using Go's log package to log messages and then Zap to add some structure to the logs. We 've also seen how we can either output the logs to the console or store them in a file. Saving logs to a file is obviously the preferable option in any real-world applications because we could need them later for debugging or analytics. But how does this work in the case of an app that is running inside a Docker container since we know that in such a case, any files created would reside inside the container and wouldn't be accessible from outside? Well, that's not strictly true. Let's see how.
Docker volumes
We've made changes to our app such that the logs get written in the app container. But how can we access them from outside the container? After all, that's where we will need them in order to check them. Besides, all local container files get destroyed if ...
