通过 ob-operator 部署 OceanBase 数据库
本文主要是介绍通过 ob-operator 部署 OceanBase 数据库，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
本文介绍如何通过 ob-operator 来部署 OceanBase 数据库。
背景信息
ob-operator 与其他 operator 一样，旨在让 OceanBase 以容器的方式，无缝运行在 Kubernetes 集群上。
ob-operator 现已支持 OceanBase 集群的创建、删除，完整的节点生命周期管理、ob-proxy 管理，后续会支持租户管理、多 Kubernetes 集群等功能。
您可按照以下步骤通过 ob-operator 来部署 OceanBase 数据库。
部署信息：
版本：3.1.4
命名空间：oceanbase-system、obcluster

A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assigment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1).

ephemeral:
description: "Ephemeral represents a volume that is handled by a cluster storage driver.

The name of the PVC will be `<pod name>-<volume name>` where `<volume name>` is the name from the `PodSpec.Volumes` array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long). \n An existing PVC with that name that is not owned by the pod will *not* be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. \n This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. \n Required, must not be nil."

This field will replace the functionality of the DataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, both fields (DataSource and DataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. There are two important differences between DataSource and DataSourceRef: * While DataSource only allows two specific types of objects, DataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While DataSource ignores disallowed values (dropping them), DataSourceRef preserves all values, and generates an error if a disallowed value is specified.

This field will replace the functionality of the DataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, both fields (DataSource and DataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. There are two important differences between DataSource and DataSourceRef: * While DataSource only allows two specific types of objects, DataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While DataSource ignores disallowed values (dropping them), DataSourceRef preserves all values, and generates an error if a disallowed value is specified. (Alpha) Using this field requires the AnyVolumeDataSource feature gate to be enabled.'

自定义部署 ob-operator
您也可以根据您的配置修改 operator.yaml。
例如在 operator.yaml 中添加启动参数 --cluster-name，含义为 ob-operator 只处理 cluster 值与自身启动参数 --cluster-name 的值相同的 CRD。
注意
--cluster-name的值需要与 obcluster 配置中的cluster配置一致。
参考以下部分配置文件进行修改：
apiVersion: apps/v1
kind: Deployment
metadata:
labels:
control-plane: controller-manager
name: ob-operator-controller-manager
namespace: oceanbase-system
spec:
replicas: 1

- --leader-elect
- --cluster-name=cn
command:
- /manager
image: ob-operator:latest
imagePullPolicy: Always
name: manager
配置 Kubernetes 节点 label
您需将 Kubernetes 节点配置 label，label 需要与 obcluster.yaml 中的 nodeSelector 配置相匹配。ob-operator 会将 Pod 调度到具有相应 label 的节点上。
推荐配置 label 的 key 为 topology.kubernetes.io/zone。不同 Zone 推荐配置不同的 label 以做容灾。
kubectl label node nodename topology.kubernetes.io/zone=zonename

自定义部署 OceanBase 集群
您也可以在 obcluster.yaml 中根据自己的配置做一些修改。
参考以下部分配置文件进行修改：
apiVersion: cloud.oceanbase.com/v1
kind: OBCluster
metadata:
name: ob-test
namespace: obcluster
spec:
imageRepo: oceanbasedev/oceanbase-cn
tag: v3.1.3-10100042022051821
clusterID: 1
topology:
- cluster: cn
zone:
- name: zone1
region: region1
nodeSelector:
topology.kubernetes.io/zone: zone1
replicas: 1
- name: zone2
region: region1
nodeSelector:
topology.kubernetes.io/zone: zone2
replicas: 1
- name: zone3
region: region1
nodeSelector:
topology.kubernetes.io/zone: zone3
replicas: 1
parameters:
- name: freeze_trigger_percentage
value: "30"
resources:
cpu: 2
memory: 10Gi
storage:
- name: data-file
storageClassName: "local-path"
size: 50Gi
- name: data-log
storageClassName: "local-path"
size: 50Gi
- name: log
storageClassName: "local-path"
size: 30Gi
主要配置介绍：
-
imageRepo：OceanBase 镜像 repo。 -
tag：OceanBase 镜像 tag。 -
cluster：按需配置，如果需要在该 Kubernetes 集群中部署 OceanBase 集群，请将 cluster 配置为与 ob-operator 启动参数--cluster-name相同。 -
parameters：按需配置, 自定义的一些 OceanBase 配置项。 -
cpu：建议配置为大于 2 的整数，小于 2 会引发系统异常。 -
memory：建议配置为大于 10 Gi 的整数，小于 10 Gi 会引发系统异常。 -
data-file：该部分为 OBServer 系统配置项datafile_size的大小，建议为 memory 的 3 倍以上。用户可以自行按需配置storageClassName。 -
data-log：该部分为 OBServer 系统配置项data_dir的大小，建议为 memory 的 5 倍以上。用户可以自行按需配置storageClassName。 -
log：该部分为 OBServer 系统日志的大小，建议为 30 Gi 以上。用户可以自行按需配置storageClassName。
部署 OBProxy
使用默认配置部署 OBProxy
kubectl apply -f https://raw.githubusercontent.com/oceanbase/ob-operator/master/deploy/obproxy.yaml
自定义部署 OBProxy
您也可以在 obproxy.yaml 中根据自己的配置做一些修改。
参考以下部分配置文件进行修改：
apiVersion: apps/v1
kind: Deployment
metadata:
name: obproxy
namespace: obcluster
spec:
selector:
matchLabels:
app: obproxy
replicas: 3
template:
metadata:
labels:
app: obproxy
spec:
containers:
- name: obproxy
image: oceanbase/obproxy-ce:3.2.3
ports:
- containerPort: 2883
name: "sql"
- containerPort: 2884
name: "prometheus"
env:
- name: APP_NAME
value: helloworld
- name: OB_CLUSTER
value: ob-test
- name: RS_LIST
value: $(SVC_OB_TEST_SERVICE_HOST):$(SVC_OB_TEST_SERVICE_PORT)
resources:
limits:
memory: 2Gi
cpu: "1"
---
apiVersion: v1
kind: Service
metadata:
name: obproxy-service
namespace: obcluster
spec:
type: NodePort
selector:
app: obproxy
ports:
- name: "tcp"
port: 2883
targetPort: 2883
nodePort: 30083
主要环境变量配置说明：
-
APP_NAME: OBProxy 的 appname。 -
OB_CLUSTER: OBProxy 连接的 OceanBase 集群名。 -
RS_LIST: OceanBase 集群的 rs_list, 这里是通过 OceanBase 集群的 service 地址来生成的，当部署好 OceanBase 集群之后，会自动产生两个环境变量SVC_OB_TEST_SERVICE_HOST,SVC_OB_TEST_SERVICE_PORT, 分别表示 OceanBase 集群的服务地址和端口。
