Kubernetes offers tools to help you manage application configuration within your cluster. This lab will give you the opportunity to get hands-on with the process of configuring your Kubernetes apps.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Create a ConfigMap
Create a ConfigMap in the
hiveNamespace calledhoney-config.Store the following data in the ConfigMap:
honey.cfg: | There is always money in the honey stand!- Create a Secret
Create a Secret called
hive-secin thehiveNamespace.Store the following value in the Secret:
hiveToken: secretToken!Note that you will need to base64-encode the
secretToken!value.- Modify the Deployment To Use the ConfigMap and Secret Data
In the
hiveNamespace, there is a Deployment calledhive-mgr. Edit this Deployment so that the container is able to access the data from the ConfigMap and Secret.For the Secret, provide the value of the
hiveTokenkey to the container as an environment variable calledTOKEN.For the ConfigMap, load the data from the
honey.cfgkey using a mounted volume. The data should ultimately be accessible by the container at the path/config/honey.cfg.
