A Custom Resource Definition for provisioning AWS RDS databases.
State: BETA - use with caution
The node running the pod should have an instance profile that allows creation and deletion of RDS databases and Subnets.
The codes will search for the first node, and take the subnets from that node. And depending on wether or not your DB should be public, then filter them on that. If any subnets left it will attach the DB to that.
You can start the the controller by applying
kubectl apply -f deploy/deployment.yaml
To create ClusterRole and bindings, apply the following instead:
kubectl apply -f deploy/operator-cluster-role.yaml kubectl apply -f deploy/operator-service-account.yaml kubectl apply -f deploy/operator-cluster-role-binding.yaml kubectl apply -f deploy/deployment-rbac.yaml
Kubernetes database provisioner Usage: k8s-rds [flags] Flags: --exclude-namespaces strings list of namespaces to exclude. Mutually exclusive with --include-namespaces. -h, --help help for k8s-rds --include-namespaces strings list of namespaces to include. Mutually exclusive with --exclude-namespaces. --provider string Type of provider (aws, local) (default "aws") --repository string Docker image repository, default is hub.docker.com)
The provider can be started in two modes:
Local - this will provision a docker image in the cluster, and providing a database that way
AWS - This will use the AWS API to create a RDS database
When the controller is running in the cluster you can deploy/create a new database by running
kubectl apply on the following
apiVersion: v1 kind: Secret metadata: name: mysecret type: Opaque data: mykey: cGFzc3dvcmRvcnNvbWV0aGluZw== --- apiVersion: k8s.io/v1 kind: Database metadata: name: pgsql namespace: default spec: class: db.t2.medium # type of the db instance engine: postgres # what engine to use postgres, mysql, aurora-postgresql etc. version: "9.6" dbname: pgsql # name of the initial created database name: pgsql # name of the database at the provider password: # link to database secret key: mykey # the key in the secret name: mysecret # the name of the secret username: postgres # Database username size: 20 # size in GB MaxAllocatedSize: 50 # size in GB backupretentionperiod: 10 # days to keep backup, 0 means diable deleteprotection: true # don't delete the database even though the object is delete in k8s encrypted: true # should the database be encrypted iops: 1000 # number of iops multiaz: true # multi AZ support storagetype: gp2 # type of the underlying storage tags: "key=value,key1=value1" provider: aws # Optional either aws or local, will overrides the value the operator was started with
After the deploy is done you should be able to see your database via
kubectl get databases
