Installation

1. Install custom resource definitions:

2. Install the operator with its RBAC rules:
   the default deployed namespace is doris, when deploy on specific namespace, please pull yaml and update namespace field.

Get Started to Deploy Doris

The Quick Start Guide have some examples to deploy doris on kubernetes. they represent some mode to deploy doris on different situation. for only deploy fe and be without persistentVolume:

kubectl apply -f https://raw.githubusercontent.com/selectdb/doris-operator/master/doc/examples/doriscluster-sample.yaml

This doriscluster-sample-storageclass.yaml displayed to deploy doris with StorageClass mode to provide persistent Volume.

Notice

1. currently operator only supports the fqdn mode to deploy doris on kubernetes. when the operator uses the official image to deploy container, the relevant work service will set the enable_fqdn_mode as true automatically. by running the doris docker container without k8s-operator, fqdn mode is closed by default. for other configurations about deploying doris on kubernetes, refer to example/doriscluster-sample-comfigmap.yaml.
2. fe and be print log by kubectl logs -ndoris -f ${pod_name} also in /opt/apache-doris/fe/log, /opt/apache-doris/be/log in pod. When have not log processing system on k8s, mount a volume for log directory is good idea. the config to mount volume for log can reference the docexample/doriscluster-sample-storageclass.yaml.
