Mayastor Helm chart for Kubernetes

![Version: 2.10.0](https://img.shields.io/badge/Version-2.10.0-informational?style=flat-square) ![Type: application](https://img.shields.io/badge/Type-application-informational?style=flat-square) ![AppVersion: 2.10.0](https://img.shields.io/badge/AppVersion-2.10.0-informational?style=flat-square)

## Installation Guide

### Prerequisites

 - Make sure the [system requirement pre-requisites](https://mayastor.gitbook.io/introduction/quickstart/prerequisites) are met.
 - Label the storage nodes same as the mayastor.nodeSelector in values.yaml
 - Create the namespace you want the chart to be installed, or pass the `--create-namespace` flag in the `helm install` command.
   ```sh
   kubectl create ns <mayastor-namespace>
   ```
 - Create secret if downloading the container images from a private repo.
   ```sh
   kubectl create secret docker-registry <same-as-image.pullSecrets[0]>  --docker-server="https://index.docker.io/v1/" --docker-username="<user-name>" --docker-password="<password>" --docker-email="<user-email>" -n <mayastor-namespace>
   ```

### Installing the chart via the git repo

Clone the mayastor charts repo.
Sync the chart dependencies
```console
$ helm dependency update
```
Install the mayastor chart using the command.
```console
$ helm install mayastor . -n <mayastor-namespace>
```

### Installing the Chart via Helm Registry

To install the chart with the release name `mymayastor`:

```console
$ helm repo add mayastor https://openebs.github.io/mayastor-extensions/
$ helm install mymayastor mayastor/mayastor
```

### Uninstall Helm Chart

```console
$ helm uninstall [RELEASE_NAME]
```

This removes all the Kubernetes components associated with the chart and deletes the release.

*See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation.*

## Values

| Key | Description | Default |
|:----|:------------|:--------|
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;allowNonPersistentDevlink | Allow using non-persistent kernel devpaths for pool disks. Enabling this will let users to use the kernel devpaths e.g /dev/sda, for diskpools. However, this comes with associated risks if the devpaths get swapped among disks, resulting in total data loss especially if encryption is being used. | `false` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;capacity.&ZeroWidthSpace;thin.&ZeroWidthSpace;poolCommitment | The allowed pool commitment limit when dealing with thin provisioned volumes. Example: If the commitment is 250 and the pool is 10GiB we can overcommit the pool up to 25GiB (create 2 10GiB and 1 5GiB volume) but no further. | `"250%"` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;capacity.&ZeroWidthSpace;thin.&ZeroWidthSpace;snapshotCommitment | When creating snapshots for an existing volume, each replica pool must have at least this much free space percentage of the volume size. Example: if this value is 40, the pool has 40GiB free, then the max volume size allowed to be snapped on the pool is 100GiB. | `"40%"` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;capacity.&ZeroWidthSpace;thin.&ZeroWidthSpace;volumeCommitment | When creating replicas for an existing volume, each replica pool must have at least this much free space percentage of the volume size. Example: if this value is 40, the pool has 40GiB free, then the max volume size allowed to be created on the pool is 100GiB. | `"40%"` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;capacity.&ZeroWidthSpace;thin.&ZeroWidthSpace;volumeCommitmentInitial | Same as the `volumeCommitment` argument, but applicable only when creating replicas for a new volume. | `"40%"` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;encryptedPoolsSoftScheduling | Prefer encrypted pools for volume replicas. If a volume wasn't provisioned with a encryption storageclass, we try to place the replicas of such volume on best-effort basis onto encrypted pools, if this global is set. This is effective subject to volume spec already modified via plugin to request encryption. | `false` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;logLevel | Log level for the core service | `"info"` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;minTimeouts | Enable minimal timeouts | `true` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;poolClusterSize | Default blobstore cluster size for diskpools, in bytes. This value is used as a default value of blobstore cluster size on diskpools. This is set to 4MiB internally by default, if nothing specified here. The value is also configurable via Diskpool CR, which takes precedence over this setting. This is an advanced configuration, please refer documentation to understand the usage and implications of this. | `""` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;priorityClassName | Set PriorityClass, overrides global. If both local and global are not set, the final deployment manifest has a mayastor custom critical priority class assigned to the pod by default. Refer the `templates/_helpers.tpl` and `templates/mayastor/agents/core/agent-core-deployment.yaml` for more details. | `""` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;rebuild.&ZeroWidthSpace;maxConcurrent | The maximum number of system-wide rebuilds permitted at any given time. If set to an empty string, there are no limits. | `""` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;rebuild.&ZeroWidthSpace;partial.&ZeroWidthSpace;enabled | Partial rebuild uses a log of missed IO to rebuild replicas which have become temporarily faulted, hence a bit faster, depending on the log size. | `true` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;rebuild.&ZeroWidthSpace;partial.&ZeroWidthSpace;waitPeriod | If a faulted replica comes back online within this time period then it will be rebuilt using the partial rebuild capability. Otherwise, the replica will be fully rebuilt. A blank value "" means internally derived value will be used. | `""` |
| agents.&ZeroWidthSpace;core.&ZeroWidthSpace;requestTimeout | Request timeout for core agents Default value is defined in .base.default_req_timeout | `nil` |
