我正在将ElasticSearch迁移到Kubernete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"
}
}
}
...和弹性搜索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）。我认为这可能是针对AWS的，我在各种论坛上看到（我认为是）同样的问题，但不适用于AWS。
非常感谢任何帮助。
