This topic describes how to add custom workloads to VMware Tanzu Kubernetes Grid Integrated Edition (TKGI) clusters.
Custom workloads define what a cluster includes out of the box. For example, you can use custom workloads to configure metrics or logging.
To add custom workloads to a TKGI-provisioned Kubernetes cluster:
Create a YAML configuration for your custom workloads. Consult the following example from the Kubernetes documentation:
apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 2 # tells deployment to run 2 pods matching the template
template: # create pods using pod definition in this template
metadata:
# unlike pod-nginx.yaml, the name is not included in the meta data as a unique name is
# generated from the deployment name
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.7.9
ports:
- containerPort: 80
To apply custom Kubernetes workloads to every cluster created on a plan, enter your YAML configuration in the (Optional) Add-ons - Use with caution field in the pane for configuring a plan in the Tanzu Kubernetes Grid Integrated Edition tile.
