我正在将 ElasticSearch 迁移到 Kubernetes 的 PetSet，但在配置 PersistentVolumeClaim 时出现问题。
我在 AWS “vol-84094e30” “vol-87e59f33” 中有两卷。两者都是 5 GiB、100/3000 IOPS、us-west-2a 可用区并且是卷类型 gp2。
我有一个卷类型的 StorageClass 定义：
{
"kind": "StorageClass",
"apiVersion": "apps/v1alpha1",
"metadata": {
"name": "fast"
},
"provisioner": "kubernetes.io/aws-ebs",
"parameters": {
"type": "gp2",
"zone": "us-west-2a"
}
}
… 两个 PersistentVolume 定义：
{
"kind": "PersistentVolume",
"apiVersion": "v1",
"metadata": {
"name": "es-persistent-vol",
"labels": {
"type": "amazonEBS"
}
},
"spec": {
"capacity": {
"storage": "5Gi"
},
"accessModes": [
"ReadWriteOnce"
],
"awsElasticBlockStore": {
"volumeID": "vol-87e59f33",
"fsType": "ext4"
}
}
}
{
"kind": "PersistentVolume",
"apiVersion": "v1",
"metadata": {
"name": "es-persistent-vol2",
"labels": {
"type": "amazonEBS"
}
},
"spec": {
"capacity": {
"storage": "5Gi"
},
"accessModes": [
"ReadWriteOnce"
],
"awsElasticBlockStore": {
"volumeID": "vol-84094e30",
"fsType": "ext4"
}
}
}
… 弹性搜索服务：
{
"apiVersion": "v1",
"kind": "Service",
"metadata": {
"name": "elasticsearch-logging",
"namespace": "kube-system",
"labels": {
"k8s-app": "elasticsearch-logging",
"kubernetes.io/name": "Elasticsearch"
}
},
"spec": {
"ports": [
{
"port": 9200,
"protocol": "TCP",
"targetPort": "db"
}
],
"selector": {
"k8s-app": "elasticsearch-logging"
}
}
}
… 和一个 Elastic Search PetSet：
{
"apiVersion": "apps/v1alpha1",
"kind": "PetSet",
"metadata": {
"name": "elasticsearch-logging-v1",
"namespace": "kube-system",
"labels": {
"k8s-app": "elasticsearch-logging",
"version": "v1",
"kubernetes.io/cluster-service": "true"
}
},
"spec": {
"serviceName": "elasticsearch-logging-v1",
"replicas": 2,
"template": {
"metadata": {
"annotations": {
"pod.beta.kubernetes.io/initialized": "true"
},
"labels": {
"app": "elasticsearch-data"
}
},
"spec": {
"containers": [
{
"image": "gcr.io/google_containers/elasticsearch:v2.4.1",
"name": "elasticsearch-logging",
"resources": {
"limits": {
"cpu": "1000m"
},
"requests": {
"cpu": "100m"
}
},
"ports": [
{
"containerPort": 9200,
"name": "db",
"protocol": "TCP"
},
{
"containerPort": 9300,
"name": "transport",
"protocol": "TCP"
}
],
"volumeMounts": [
{
"name": "es-persistent-storage",
"mountPath": "/data"
}
]
}
]
}
},
"volumeClaimTemplates": [
{
"metadata": {
"name": "es-persistent-storage",
"annotations": {
"volume.beta.kubernetes.io/storage-class": "fast"
},
"labels": {
"type": "amazonEBS"
}
},
"spec": {
"accessModes": [
"ReadWriteOnce"
],
"resources": {
"requests": {
"storage": "5Gi"
}
}
}
}
]
}
}
当我创建所有这些时，PersistentStorageVolume（在 PetSet 中定义）无法配置卷（ProvisioningFailed - 没有匹配的卷插件）。我认为这可能是 AWS 特定的，我在各种论坛上查看过（我认为是）同样的问题，但不适用于 AWS。
任何帮助深表感谢。
