We have also seen how to create ConfigMaps and Secrets and associate them with our containers via CLI. Running everything via the command line will facilitate the automation of these steps and improve the overall agility of your application.

Associating data with containers enables us to use the same container across different environments in our IT systems (for example, in test and production). Using the same container across different environments provides a way for secure and trusted code promotion techniques for IT processes. Each team can use a container as a unit of deployment and sign the container so that other parties can trust the container. This also provides a trusted way of distributing code not...
