Kubernetes Cookbook - Second Edition

Getting ready

Before using Secrets, we have to keep in mind that Secret should be always created before dependent Pods, so dependent Pods can reference it properly. In addition, Secrets have a 1 MB size limitation. It works properly for defining a bunch of information in a single Secret. However, Secret is not designed for storing large amounts of data. For configuration data, consider using ConfigMaps. For large amounts of non-sensitive data, consider using volumes instead.
