Cluster
kubernetes cluster is made up of components such as control plane(master), config store i.e etcd and worker nodes.
spawner allows user to create a kubernetes cluster in the following cloud providers
AWS
Azure
Creating cluster
request.json is a cluster specification file with the following fields
API fields ( *required)
| field | description | Default |
|---|---|---|
provider* | Backend cloud provider for infra. such | |
region* | hosted region for infra, this might change as per provider. | |
accountName | when using with netbook connect, you can specify the connect user whose behalf the request is made to provider. In local run this will be ignored and config provided credentials wil be used | |
clusterName* | Name of the cluster to be created | |
nodeSpec | optional node specification. azure requires you to provide default system pool. Required for azure, ignored in case of aws cluster creation. Refer nodes | |
labels | set of pair of key values. The cluster will be tagged with this ex: { created_at: sometime, by: bob} |
Cluster creation takes time depending on the provider, spawner behaves differently depending on the provider
AWS: submit request to aws and return immediately.
azure: wait until cluster created and returns. TCluster and other resources (node) creation faster than other providers
