Kubernetes 1.20.15 高可用方案：部署 Milvus v2.1.1、etcd v3.5.0 和 Minio，并设置密钥和环境变量

以下是部署 Milvus v2.1.1，etcd v3.5.0，minio:RELEASE.2023-04-07T05-28-58Z 的 YAML 文件，使用了高可用方案。同时，给出了设置 MINIO_ACCESS_KEY 和 MINIO_SECRET_KEY 密钥的代码，以及设置 Milvus 环境变量 ETCD_ENDPOINTS 和 MINIO_ADDRESS 的代码。

milvus.yaml：

        ports:
        - containerPort: 2379
          name: client
        - containerPort: 2380

        volumeMounts:

        - name: MINIO_ADDRESS
          value: 'http://minio-0.minio:9000'

设置 MINIO_ACCESS_KEY 和 MINIO_SECRET_KEY 密钥的代码：

kubectl create secret generic minio-credentials --from-literal=accesskey='your-minio-access-key' --from-literal=secretkey='your-minio-secret-key' -n milvus

设置 Milvus 环境变量 ETCD_ENDPOINTS 和 MINIO_ADDRESS 的代码：

kubectl set env statefulset/milvus ETCD_ENDPOINTS=etcd-0.etcd:2379,etcd-1.etcd:2379,etcd-2.etcd:2379 -n milvus
kubectl set env statefulset/milvus MINIO_ADDRESS=http://minio-0.minio:9000 -n milvus
