ClickHouse on CCE部署指南

云容器引擎 CCE-示例:Simple example

Simple example 本示例来源于https://github.com/Altinity/clickhouse-operator/blob/master/docs/chi-examples/01-simple-layout-01-1shard-1repl.yaml。 yaml文件如下： apiVersion: "clickhouse.altinity.com/v1"kind: "ClickHouseInstallation"metadata: name: "simple-01" 使用如下命令创建： kubectl apply -n test-clickhouse-operator -f https://raw.githubusercontent.com/Altinity/clickhouse-operator/master/docs/chi-examples/01-simple-layout-01-1shard-1repl.yaml 一段时间后，查看资源运行情况： kubectl get pod -n test-clickhouse-operator kubectl get service -n test-clickhouse-operator 连接ClickHouse Database： kubectl -n test-clickhouse-operator exec -ti chi-simple-01-cluster-0-0-0 -- clickhouse-client

云容器引擎 CCE-示例:Simple Persistent Volume Example

Simple Persistent Volume Example 本示例来源于https://github.com/Altinity/clickhouse-operator/blob/master/docs/chi-examples/03-persistent-volume-01-default-volume.yaml。在CCE使用PVC时，yaml文件需做一些适配：使用云硬盘存储卷EVS 创建storageClass CCE默认支持的csi-disk为SAS类型的云硬盘。若想使用超高I/O类型的云硬盘，需要创建对应的storageClass。 vim csi-disk-ssd.yaml 复制以下内容： allowVolumeExpansion: trueapiVersion: storage.k8s.io/v1kind: StorageClassmetadata: name: csi-disk-ssdparameters: csi.storage.k8s.io/csi-driver-name: disk.csi.everest.io csi.storage.k8s.io/fstype: ext4 everest.io/disk-volume-type: SSD everest.io/passthrough: "true"provisioner: everest-csi-provisionerreclaimPolicy: DeletevolumeBindingMode: Immediate 保存后退出： kubectl create -f csi-disk-ssd.yaml accessModes需填写为ReadWriteOnce。添加storageClassName: csi-disk-ssd。使用文件存储卷SFS accessModes需填写为ReadWriteMany。添加storageClassName: csi-nas。下面以文件存储卷SFS为例，yaml文件如下： apiVersion: "clickhouse.altinity.com/v1"kind: "ClickHouseInstallation"metadata: name: "pv-simple"spec: defaults: templates: dataVolumeClaimTemplate: data-volume-template logVolumeClaimTemplate: log-volume-template configuration: clusters: - name: "simple" layout: shardsCount: 1 replicasCount: 1 templates: volumeClaimTemplates: - name: data-volume-template spec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi storageClassName: csi-nas - name: log-volume-template spec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi storageClassName: csi-nas 使用如下命令创建： kubectl -n test-clickhouse-operator create -f 03-persistent-volume-01-default-volume.yaml 一段时间后，查看资源运行情况： kubectl get pvc -n test-clickhouse-operator kubectl get pod -n test-clickhouse-operator 查看存储卷挂载情况： kubectl -n test-clickhouse-operator exec -ti chi-pv-simple-simple-0-0-0 -c clickhouse bash df -h 连接ClickHouse Database： kubectl -n test-clickhouse-operator exec -ti chi-pv-simple-simple-0-0-0 -- clickhouse-client
