If you are using KiND, a local path provisioner will be created automatically. If you don't have a storage provisioner or don't want to use persistence volume, you could use an `emptyDir` as volume. + +```yaml +# etcd-headless.yaml +apiVersion: v1 +kind: Service +metadata: + name: etcd-headless + labels: + app.kubernetes.io/name: etcd + annotations: + service.alpha.kubernetes.io/tolerate-unready-endpoints: "true" +spec: + type: ClusterIP + clusterIP: None + ports: + - name: "client" + port: 2379 + targetPort: client + - name: "peer" + port: 2380 + targetPort: peer + selector: + app.kubernetes.io/name: etcd +--- +# etcd.yaml +apiVersion: apps/v1 +kind: StatefulSet +metadata: + name: etcd + labels: + app.kubernetes.io/name: etcd +spec: + selector: + matchLabels: + app.kubernetes.io/name: etcd + serviceName: etcd-headless + podManagementPolicy: Parallel + replicas: 1 + updateStrategy: + type: RollingUpdate + template: + metadata: + labels: + app.kubernetes.io/name: etcd + spec: + securityContext: + fsGroup: 1001 + runAsUser: 1001 + containers: + - name: etcd + image: docker.io/bitnami/etcd:3.4.14-debian-10-r0 + imagePullPolicy: "IfNotPresent" + # command: + # - /scripts/setup.sh + env: + - name: BITNAMI_DEBUG + value: "false" + - name: MY_POD_IP + valueFrom: + fieldRef: + fieldPath: status.podIP + - name: MY_POD_NAME + valueFrom: + fieldRef: + fieldPath: metadata.name + - name: ETCDCTL_API + value: "3" + - name: ETCD_NAME + value: "$(MY_POD_NAME)" + - name: ETCD_DATA_DIR + value: /etcd/data + - name: ETCD_ADVERTISE_CLIENT_URLS + value: "http://$(MY_POD_NAME).etcd-headless.apisix.svc.cluster.local:2379" + - name: ETCD_LISTEN_CLIENT_URLS + value: "http://0.0.0.0:2379"; + - name: ETCD_INITIAL_ADVERTISE_PEER_URLS + value: "http://$(MY_POD_NAME).etcd-headless.apisix.svc.cluster.local:2380" + - name: ETCD_LISTEN_PEER_URLS + value: "http://0.0.0.0:2380"; + - name: ALLOW_NONE_AUTHENTICATION + value: "yes" + ports: + - name: client + containerPort: 2379 + - name: peer + containerPort: 2380 + volumeMounts: + - name: data + mountPath: /etcd + volumeClaimTemplates: + - metadata: + name: data + spec: + accessModes: + - "ReadWriteOnce" + resources: + requests: + storage: "8Gi" +``` + +Apply these two yaml files to Kubernetes, wait few seconds, etcd installation should be successful.

If you want to deploy a production-ready etcd, please refer [bitnami/etcd](https://bitnami.com/stack/etcd/helm). + +## APISIX Installation + +Create a config file for our APISIX.
