Kubernetes Deployment Configuration: dw-glaucus

This Kubernetes deployment configuration defines a deployment named 'dw-glaucus' with a single replica of the 'glaucus-service' image. It utilizes a secret named 'dw-private-secret' for sensitive environment variables and mounts various volumes for configuration, logging, and installation files.

dw-private-secret is a reference to a Kubernetes secret named 'dw-private-secret'. A Kubernetes secret is an object that contains sensitive information, such as passwords, API keys, or certificates. In this case, the 'dw-private-secret' secret is being used as an environment variable source for the containers in the deployment. The secret provides the necessary sensitive information to the containers without exposing it in the deployment configuration.

Key Components:

• apiVersion: Specifies the Kubernetes API version used for this configuration.
• kind: Indicates the type of object, which is a Deployment in this case.
• metadata: Contains metadata about the deployment, including its name and labels.
• spec: Defines the deployment's specifications, including the number of replicas, the deployment strategy, and the pod template.
• template: Defines the pod template that will be used to create pods for the deployment.
• containers: Defines the containers within the pod, including the image, image pull policy, environment variables, and volume mounts.
• envFrom: Defines the source for environment variables, in this case, the 'dw-private-secret' secret.
• volumeMounts: Defines the volumes to be mounted into the container and their mount paths.
• volumes: Defines the volumes used in the deployment, including the 'dw-glaucus-config' ConfigMap, 'glaucus-log' PersistentVolumeClaim, and 'filebeat-install-files' host path volume.

Summary:

This deployment configuration sets up a deployment named 'dw-glaucus' that runs the 'glaucus-service' image. It leverages a Kubernetes secret named 'dw-private-secret' to securely manage environment variables. It also mounts various volumes to provide necessary configuration, logging, and installation files.
