|
||
# Configuration
|
||
|
||
~> **Important Note:** This chart is not compatible with Helm 2. Please use Helm 3 with this chart.
|
||
|
||
The chart is highly customizable using
|
||
[Helm configuration values](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing).
|
||
Each value has a default tuned for an optimal getting started experience
|
||
with Vault. Before going into production, please review the parameters below
|
||
and consider if they're appropriate for your deployment.
|
||
|
||
- `global` - These global values affect multiple components of the chart.
|
||
|
||
- `enabled` (`boolean: true`) - The master enabled/disabled configuration. If this is true, most components will be installed by default. If this is false, no components will be installed by default and manually opting-in is required, such as by setting `server.enabled` to true.
|
||
|
||
- `imagePullSecrets` (`array: []`) - References secrets to be used when pulling images from private registries. See [Pull an Image from a Private Registry](https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/) for more details. May be specified as an array of name map entries or just as an array of names:
|
||
|
||
```yaml
|
||
imagePullSecrets:
|
||
- name: image-pull-secret
|
||
# or

|
||
- image-pull-secret
|
||
```
|
||
|
||
- `tlsDisable` (`boolean: true`) - When set to `true`, changes URLs from `https` to `http` (such as the `VAULT_ADDR=http://127.0.0.1:8200` environment variable set on the Vault pods).
|
||
|
||
- `openshift` (`boolean: false`) - If `true`, enables configuration specific to OpenShift such as NetworkPolicy, SecurityContext, and Route.
|
||
|
||
- `psp` - Values that configure Pod Security Policy.

|
||
- `externalVaultAddr` (`string: ""`) - External vault server address for the injector to use. Setting this will disable deployment of the vault server, and only deploy the injector.

|
||
|
||

|
||
|
||

|
||
|
||
- `staticSecretRenderInterval` (`string: ""`) - Configures how often Vault Agent Template should render non-leased secrets such as KV v2. See the [Vault Agent Templates documentation] (/docs/agent/template#non-renewable-secrets) for more details.

- `resources` (`dictionary: {}`) - The resource requests and limits (CPU, memory, etc.) for each container of the server. This should be a YAML dictionary of a Kubernetes [ResourceRequirements](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.15/#resourcerequirements-v1-core) object. If this isn't specified, then the pods won't request any specific amount of resources, which limits the ability for Kubernetes to make efficient use of compute resources.<br /> **Setting this is highly recommended.**
|
||
|
||
```yaml
|
||
resources:
|
||
requests:
|
||
memory: '256Mi'
|
||
cpu: '250m'

cpu: '250m'
|
||
```
|
||
|
||
- `namespaceSelector` (`dictionary: {}`) - The selector used by the admission webhook controller to limit what namespaces where injection can happen. If set to null, all non-system namespaces are eligible for injection.
|
||

# Selectors are defined as a YAML dictionary.
|
||
# In this example, all namespaces with the label "injection: enabled" are eligible:
|
||
namespaceSelector:
|
||
matchLabels:
|
||
injection: enabled
|
||
```
|
||
|
||
- `objectSelector` (`dictionary: {}`) - The selector used by the admission webhook controller to limit what objects can be effected by mutation.
|
||
|
||
```yaml
|

|
||
```
|
||
|
||
- `certs` - The certs section configures how the webhook TLS certs are configured. These are the TLS certs for the Kube apiserver communicating to the webhook. By default, the injector will generate and manage its own certs, but this requires the ability for the injector to update its own `MutatingWebhookConfiguration`. In a production environment, custom certs should probably be used. Configure the values below to enable this.
|
||
|
||
- `secretName` (`string: ""`) - secretName is the name of the Kubernetes secret that has the TLS certificate and private key to serve the injector webhook. If this is null, then the injector will default to its automatic management mode.
|
||
|
||
- `caBundle` (`string: ""`) - The PEM-encoded CA public certificate bundle for the TLS certificate served by the injector. This must be specified as a string and can't come from a secret because it must be statically configured on the Kubernetes `MutatingAdmissionWebhook` resource. This only needs to be specified if `secretName` is not null.
|
||
|
||
- `certName` (`string: "tls.crt"`) - The name of the certificate file within the `secretName` secret.
|
||
|
||
- `keyName` (`string: "tls.key"`) - The name of the key file within the `secretName` secret.
|
||
|
||
- `extraEnvironmentVars` (`dictionary: {}`) - Extra environment variables to set in the injector deployment.

This can either be multi-line string or YAML matching the PodSpec's affinity field. It defaults to allowing only a single pod on each node, which minimizes risk of the cluster becoming unusable if a node is lost. If you need to run more pods per node (for example, testing on Minikube), set this value to `null`.
|
||
|
||
```yaml
|
||
# Recommended default server affinity:
|

|
||
|
||
- `volumes` (`array: []`) - A list of volumes made available to all containers. This takes
|
||
standard Kubernetes volume definitions.

|
||
- name: plugins
|
||
emptyDir: {}
|
||
```
|
||
|
||
- `volumeMounts` (`array: []`) - A list of volumes mounts made available to all containers. This takes

name: plugins
|
||
readOnly: true
|
||
```
|
||
|
||
- `resources` (`dictionary: {}`) - The resource requests and limits (CPU, memory, etc.) for each of the CSI containers. This should be a YAML dictionary of a Kubernetes [ResourceRequirements](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.15/#resourcerequirements-v1-core) objects. If this isn't specified, then the pods won't request any specific amount of resources, which limits the ability for Kubernetes to make efficient use of compute resources.<br /> **Setting this is highly recommended.**
|
||
|
||
```yaml
|
||
resources:
|
||
requests:
|
||
memory: '10Gi'
|
||
limits:
|
||
memory: '10Gi'
|
||
```

|
||
|
||
- `pod` - Values that configure the Vault CSI Provider pod.
|
||
|
||
- `annotations` (`dictionary: {}`) - This value defines additional annotations to
|
||
add to the Vault CSI Provider pods. This can either be YAML or a YAML-formatted
|
||
multi-line templated string.
|
||
|
||
```yaml
|
||
annotations:

||
# or
|
||
annotations: |
|
||
foo: bar

|
||
- `serviceAccount` - Values that configure the Vault CSI Provider's serviceaccount.
|
||
|
||
- `annotations` (`dictionary: {}`) - This value defines additional
|
||
annotations for the serviceAccount definition. This can either be YAML or
|
||
a YAML-formatted multi-line templated string.
|
||
|
||
```yaml
|
||
annotations:
|
||
foo: bar
|
||
# or
|
||
annotations: |
|
||
foo: bar
|
||
```
|
||
|
||
- `readinessProbe` - Values that configure the readiness probe for the Vault CSI Provider pods.
|
||
|
||
