What problem does this PR solve?
Add schema for TiDB config.
What is changed and how does it work?
Consume OpenAPI Schema of TidbCluster:
-
For kube-apiserver 1.15+
curl ${APISERVER_ENDPOINT}/openapi/v2 -
Earlier versions:
import "github.com/pingcap/tidb-operator/pkg/apis/pingcap/v1alpha1"
# call v1alpha1.GetOpenAPIDefinition
Basic OpenAPI schema validation:
> cat tidb-cluster.yaml
...
config:
host: "0.0.0.0"
port: 9000
> kubectl apply tidb-cluster.yaml
tidbcluster.pingcap.com/test configured
> cat tidb-cluster.yaml
...
config:
host: "0.0.0.0"
port: "9000"
> kubectl apply -f tidb-cluster.yaml
The TidbCluster "test" is invalid ...... validation failure list:
spec.tidb.config.port in body must be of type integer: "string"
