`VMCluster` represents a high-available and fault-tolerant version of VictoriaMetrics database.
|
|
The `VMCluster` CRD defines a [cluster version VM](https://docs.victoriametrics.com/Cluster-VictoriaMetrics).
|
|
|
|
For each `VMCluster` resource, the Operator creates:
|
|
|
|
- `VMStorage` as `StatefulSet`,
|
|
- `VMSelect` as `StatefulSet`
|
|
- and `VMInsert` as deployment.
|
|
|
|
For `VMStorage` and `VMSelect` headless services are created. `VMInsert` is created as service with clusterIP.
|
|
|
|
There is a strict order for these objects creation and reconciliation:
|
|
|
|
1. `VMStorage` is synced - the Operator waits until all its pods are ready;
|
|
1. Then it syncs `VMSelect` with the same manner;
|
|
1. `VMInsert` is the last object to sync.
|
|
|
|
All [statefulsets](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/) are created
|
|
with [OnDelete](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#on-delete) update type.
|
|
It allows to manually manage the rolling update process for Operator by deleting pods one by one and waiting for the ready status.
|
|
|
|
Rolling update process may be configured by the operator env variables.
|
|
The most important is `VM_PODWAITREADYTIMEOUT=80s` - it controls how long to wait for pod's ready status.
|
|
|
|
## Specification
|
|
|
|
You can see the full actual specification of the `VMCluster` resource in the **[API docs -> VMCluster](https://docs.victoriametrics.com/operator/api#vmcluster)**.
|
|
|
|
If you can't find necessary field in the specification of the custom resource,
|
|
see [Extra arguments section](./#extra-arguments).
|
|
|
|
Also, you can check out the [examples](#examples) section.
|
|
|
|
## Requests Load-Balancing
|
|
|
|
Operator provides enhanced load-balancing mechanism for `vminsert` and `vmselect` clients. By default, operator uses built-in Kubernetes [service]() with `clusterIP` type for clients connection. It's good solution for short lived connections. But it acts poorly with long-lived TCP sessions and leads to the uneven resources utilisation for `vmselect` and `vminsert` components.
|
|
|
|
Consider the following example:
|
|
|
|
|
|
|
|
In this case clients could establish multiple connections to the same `pod` via `service`. And client requests will be served only by subset of `pods`.
|
|
|
|
Operator allows to tweak this behaviour with enabled `requestsLoadbalacing`:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMCluster
|
|
metadata:
|
|
name: with-balanacer
|
|
spec:
|
|
retentionPeriod: "4"
|
|
replicationFactor: 1
|
|
requestsLoadBalancer:
|
|
enabled: true
|
|
spec:
|
|
replicaCount: 2
|
|
```
|
|
|
|
Operator will deploy `VMAuth` deployment with 2 replicas. And update vminsert and vmselect services to point to `vmauth`.
|
|
In addition, operator will create 3 additional services with the following pattern:
|
|
|
|
- vminsertinternal-CLUSTER_NAME - needed for vmselect pod discovery
|
|
- vmselectinternal-CLUSTER_NAME - needed for vminsert pod discovery
|
|
- vmclusterlb-CLUSTER_NAME - needed for metrics collection and exposing `vmselect` and `vminsert` components via `VMAuth` balancer.
|
|
|
|
Network scheme with load-balancing:
|
|
|
|
|
|
Operator allows to customise load-balancing configuration with `requestsLoadBalancer.Spec` settings.
|
|
|
|
## High availability
|
|
|
|
The cluster version provides a full set of high availability features - metrics replication, node failover, horizontal scaling.
|
|
|
|
First, we recommend familiarizing yourself with the high availability tools provided by "VictoriaMetrics Cluster" itself:
|
|
|
|
- [High availability](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#high-availability),
|
|
- [Cluster availability](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#cluster-availability),
|
|
- [Replication and data safety](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#replication-and-data-safety).
|
|
|
|
`VMCluster` supports all listed in the above-mentioned articles parameters and features:
|
|
|
|
- `replicationFactor` - the number of replicas for each metric.
|
|
- for every component of cluster (`vmstorage` / `vmselect` / `vminsert`):
|
|
- `replicaCount` - the number of replicas for components of cluster.
|
|
- `affinity` - the affinity (the pod's scheduling constraints) for components pods. See more details in [kubernetes docs](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#affinity-and-anti-affinity).
|
|
- `topologySpreadConstraints` - controls how pods are spread across your cluster among failure-domains such as regions, zones, nodes, and other user-defined topology domains. See more details in [kubernetes docs](https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/).
|
|
|
|
In addition, operator:
|
|
|
|
- uses k8s services or vmauth for load balancing between `vminsert` and `vmselect` components,
|
|
- uses health checks for to determine the readiness of components for work after restart,
|
|
- allows to horizontally scale all cluster components just by changing `replicaCount` field.
|
|
|
|
Here is an example of a `VMCluster` resource with HA features:
|
|
|
|
```yaml
|
|

|
|
```
|
|
|
|
## Version management
|
|
|
|
For `VMCluster` you can specify tag name from [releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) and repository setting per cluster object:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMCluster
|
|
metadata:
|
|
name: example-vmcluster
|
|
spec:
|
|
vmstorage:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vmstorage
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
vmselect:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vmselect
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
vminsert:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vminsert
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
```
|
|
|
|
Also, you can specify `imagePullSecrets` if you are pulling images from private repo,
|
|
but `imagePullSecrets` is global setting for all `VMCluster` specification:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMCluster
|
|
metadata:
|
|
name: example-vmcluster
|
|
spec:
|
|
vmstorage:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vmstorage
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
vmselect:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vmselect
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
vminsert:
|
|
replicaCount: 2
|
|
image:
|
|
repository: victoriametrics/vminsert
|
|
tag: v1.93.4-cluster
|
|
pullPolicy: Always
|
|
imagePullSecrets:
|
|
- name: my-repo-secret
|
|
# ...
|
|
```
|
|
|
|
## Resource management
|
|
|
|
You can specify resources for each component of `VMCluster` resource in the `spec` section of the `VMCluster` CRD.
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMCluster
|
|
metadata:
|
|
name: vmcluster-resources-example
|
|
spec:
|
|
# ...
|
|
vmstorage:
|
|
resources:
|
|
requests:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
limits:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
# ...
|
|
vmselect:
|
|
resources:
|
|
requests:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
limits:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
# ...
|
|
vminsert:
|
|
resources:
|
|
requests:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
limits:
|
|
memory: "16Gi"
|
|
cpu: "4"
|
|
# ...
|
|
```
|
|
|
|
If these parameters are not specified, then,
|
|
by default all `VMCluster` pods have resource requests and limits from the default values of the following [operator parameters](https://docs.victoriametrics.com/operator/configuration):
|
|
|
|
- `VM_VMCLUSTERDEFAULT_VMSTORAGEDEFAULT_RESOURCE_LIMIT_MEM` - default memory limit for `VMCluster/vmstorage` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSTORAGEDEFAULT_RESOURCE_LIMIT_CPU` - default memory limit for `VMCluster/vmstorage` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSTORAGEDEFAULT_RESOURCE_REQUEST_MEM` - default memory limit for `VMCluster/vmstorage` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSTORAGEDEFAULT_RESOURCE_REQUEST_CPU` - default memory limit for `VMCluster/vmstorage` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSELECTDEFAULT_RESOURCE_LIMIT_MEM` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSELECTDEFAULT_RESOURCE_LIMIT_CPU` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSELECTDEFAULT_RESOURCE_REQUEST_MEM` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMSELECTDEFAULT_RESOURCE_REQUEST_CPU` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMINSERTDEFAULT_RESOURCE_LIMIT_MEM` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMINSERTDEFAULT_RESOURCE_LIMIT_CPU` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMINSERTDEFAULT_RESOURCE_REQUEST_MEM` - default memory limit for `VMCluster/vmselect` pods,
|
|
- `VM_VMCLUSTERDEFAULT_VMINSERTDEFAULT_RESOURCE_REQUEST_CPU` - default memory limit for `VMCluster/vmselect` pods.
|
|
|
|
These default parameters will be used if:
|
|
|
|
- `VM_VMCLUSTERDEFAULT_USEDEFAULTRESOURCES` is set to `true` (default value),
|
|
- `VMCluster/*` CR doesn't have `resources` field in `spec` section.
|
|
|
|
Field `resources` in `VMCluster/*` spec have higher priority than operator parameters.
|
|
|
|
If you set `VM_VMCLUSTERDEFAULT_USEDEFAULTRESOURCES` to `false` and don't specify `resources` in `VMCluster/*` CRD,
|
|
then `VMCluste/*r` pods will be created without resource requests and limits.
|
|
|
|
Also, you can specify requests without limits - in this case default values for limits will not be used.
|
|
|
|
## Enterprise features
|
|
|
|
VMCluster supports following features
|
|
from [VictoriaMetrics Enterprise](https://docs.victoriametrics.com/enterprise#victoriametrics-enterprise):
|
|
|
|
- [Downsampling](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#downsampling)
|
|
- [Multiple retentions / Retention filters](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#retention-filters)
|
|
- [Advanced per-tenant statistic](https://docs.victoriametrics.com/pertenantstatistic)
|
|
- [mTLS for cluster components](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#mtls-protection)
|
|
- [Backup automation](https://docs.victoriametrics.com/vmbackupmanager)
|
|
|
|
VMCluster doesn't support yet feature
|
|
[Automatic discovery for vmstorage nodes](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#automatic-vmstorage-discovery).
|
|
|
|
For using Enterprise version of [vmcluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics)
|
|
you need to change version of `VMCluster` to version with `-enterprise` suffix using [Version management](#version-management).
|
|
|
|
All the enterprise apps require `-eula` command-line flag to be passed to them.
|
|
This flag acknowledges that your usage fits one of the cases listed on [this page](https://docs.victoriametrics.com/enterprise#victoriametrics-enterprise).
|
|
So you can use [extraArgs](./#extra-arguments) for passing this flag to `VMCluster`.
|
|
|
|
### Downsampling
|
|
|
|
After that you can pass [Downsampling](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#downsampling)
|
|
flag to `VMCluster/vmselect` and `VMCluster/vmstorage` with [extraArgs](./#extra-arguments) too.
|
|
|
|
Here are complete example for [Downsampling](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#downsampling):
|
|
|
|
```yaml
|
|

|
|
|
|
### Retention filters
|
|
|
|
You can pass [Retention filters](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#retention-filters)
|
|
flag to `VMCluster/vmstorage` with [extraArgs](./#extra-arguments).
|
|
|
|
Here are complete example for [Retention filters](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#retention-filters):
|
|
|
|
```yaml
|
|

|
|
|
|
# ...other fields...
|
|
```
|
|
|
|
### Advanced per-tenant statistic
|
|
|
|
For using [Advanced per-tenant statistic](https://docs.victoriametrics.com/PerTenantStatistic)
|
|
you only need to [enable Enterprise version of vmcluster components](#enterprise-features)
|
|
and operator will automatically create
|
|
[Scrape objects](https://docs.victoriametrics.com/operator/resources/vmagent#scraping) for cluster components.
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|

```
|
|
|
|
After that [VMAgent](https://docs.victoriametrics.com/operator/resources/vmagent) will automatically
|
|
scrape [Advanced per-tenant statistic](https://docs.victoriametrics.com/PerTenantStatistic) for cluster components.
|
|
|
|
### mTLS protection
|
|
|
|
You can pass [mTLS protection](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#mtls-protection)
|
|
flags to `VMCluster/vmstorage`, `VMCluster/vmselect` and `VMCluster/vminsert` with [extraArgs](./#extra-arguments) and mount secret files
|
|
with `extraVolumes` and `extraVolumeMounts` fields.
|
|
|
|
Here are complete example for [mTLS protection](https://docs.victoriametrics.com/Cluster-VictoriaMetrics#mtls-protection)
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1

### Backup automation
|
|
|
|
You can check [vmbackupmanager documentation](https://docs.victoriametrics.com/vmbackupmanager) for backup automation.
|
|
It contains a description of the service and its features. This section covers vmbackumanager integration in vmoperator.
|
|
|
|
`VMCluster` has built-in backup configuration, it uses `vmbackupmanager` - proprietary tool for backups.
|
|
It supports incremental backups (hourly, daily, weekly, monthly) with popular object storages (aws s3, google cloud storage).
|
|
|
|
Here is a complete example for backup configuration:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMCluster
|
|
metadata:
|
|
name: vmcluster-ent-example
|
|
spec:
|
|
|
|
vmstorage:
|
|
vmBackup:
|
|
# should be true and means that you have the legal right to run a vmstorage enterprise
|
|
# that can either be a signed contract or an email with confirmation to run the service in a trial period
|
|
# https://victoriametrics.com/legal/esa/
|
|
acceptEULA: true
|
|
|
|
# using enterprise features: Backup automation
|
|
# more details about backup automation you can read on https://docs.victoriametrics.com/vmbackupmanager
|
|
destination: "s3://your_bucket/folder"
|
|
credentialsSecret:
|
|
name: remote-storage-keys
|
|
key: credentials
|
|
|
|
# ...other fields...
|
|
|
|
---
|
|
|
|
apiVersion: v1
|
|
kind: Secret
|
|
metadata:
|
|
name: remote-storage-keys
|
|
type: Opaque
|
|
stringData:
|
|
credentials: |-
|
|
[default]
|
|
aws_access_key_id = your_access_key_id
|
|
aws_secret_access_key = your_secret_access_key
|
|
```
|
|
|
|
**NOTE**: for cluster version operator adds suffix for destination: `"s3://your_bucket/folder"`, it becomes `"s3://your_bucket/folder/$(POD_NAME)"`.
|
|
It's needed to make consistent backups for each storage node.
|
|
|
|
You can read more about backup configuration options and mechanics [here](https://docs.victoriametrics.com/vmbackupmanager)
|
|
|
|
Possible configuration options for backup crd can be found at [link](https://docs.victoriametrics.com/operator/api#vmbackup)
|
|
|
|
**Using VMBackupmanager for restoring backups** in Kubernetes environment is described [here](https://docs.victoriametrics.com/vmbackupmanager#how-to-restore-in-kubernetes).
|
|
|
|
Also see VMCluster example spec [here](https://github.com/VictoriaMetrics/operator/blob/master/config/examples/vmcluster_with_backuper.yaml).
