Selecting Cluster Nodes
You can use Kubernetes Node Selector to specify a set of nodes of the cluster on which Akamas containers will be scheduled.
To do so you should first look for a label common to all those nodes or create a new one. You can read more about labels in Kubernetes in the official documentation.
Once you have defined a label (say nodeRole: akamas
), you can edit the values.yaml file defined in the Installing Akamas section adding the following properties.
# Node selector for core akamas services
nodeSelector:
nodeRole: akamas
# Node selector for elasticsearch database
elasticsearch:
nodeSelector:
nodeRole: akamas
# Node selector for postgresql database
postgresql:
primary:
nodeSelector:
nodeRole: akamas
# Node selector for airflow
airflow:
nodeSelector:
nodeRole: akamas
You can then re-apply the chart using the helm upgrade
command.
