Kubernetes version: 1.9
This operator use the kubernetes code-generator for
- clientset: used to manipulate objects defined in the CRD (cassandraCluster)
- informers: cache for registering to events on objects defined in the CRD
- listers
- deep copy
- Initialize the dependancies with
dep init
in the project root directory - Clone the code-generator repo in the
vendor/k8s.io
directory. Be careful of cloning the branch matching the Kubernetes versiongit clone -b <branch> https://github.com/kubernetes/code-generator
- Run the script
vendor/k8s.io/code-generator/generate-groups.sh all github.com/vgkowski/cassandra-operator/pkg/client github.com/vgkowski/cassandra-operator/pkg/apis cassandra:v1
- Currently the relationship between native Kubernetes objects and CassandraClusters is done with the name which is equal.
For multiple resources of the same type (services for instance) a postfix is added to the name ("-internode" for internode service and "-access" for access service)
A better option would be to use the
metadata.ownerReference
but it requires to search and get objects by this reference instead of by name. For indexed objects like Pods or PVCs the search and get is done through the labelCassandraCluster
which contains the name of the cluster - Implement proper Cassandra admin logic (current code isn't working)
