Kubernetes environment variables boolean

With Kubernetes, we can orchestrate our containers across multiple hosts, scale the containerized applications with all resources on the fly, and have centralized container management environment. In this tutorial, I will show you step-by-step how to install and configure Kubernetes on CentOS 7. The coreos-kubernetes and coreos-baremetal repos both support configuring rkt as the Kubernetes runtime out of the box. Check out the coreos-kubernetes repo if you want to spin up a cluster on AWS or locally with Vagrant. The common configuration option here is setting CONTAINER_RUNTIME environment variable to rkt. Most of the components provided in this project need to know the namespace. For Kubernetes (1.3+), the namespace is made available to the pod as part of the service account secret and is automatically detected by the client. For earlier versions, it needs to be specified as an environment variable to the pod. A quick way to do this is as follows: envVars Environment variables that are applied to ALL containers. envVar An environment variable whose value is defined inline. secretEnvVar An environment variable whose value is derived from a Kubernetes secret. imagePullSecrets List of pull secret names, to pull images from a private Docker registry. annotations Annotations to apply to the pod.

I'm moving an existing application into a Kubernetes deployment and need to decide how to handle secrets. Currently, settings for this application like database connection strings are in plaintext config files in the repository. This is obviously not ideal. It looks like Secrets are the sensible way to manage this. Adding environment variables. You can set environment variables in your container without altering the container image by using one of the options below. However, you should verify Terminal > Integrated: Inherit Env is checked in settings or the variables you set may not appear in the Integrated Terminal.
