Each value has a sane default tuned for an optimal getting started experience
with Consul. Before going into production, please review the parameters below
and consider if they're appropriate for your deployment.
- `global` ((#v-global)) - Holds values that affect multiple components of the chart.
- `enabled` ((#v-global-enabled)) (`boolean: true`) - The master enabled/disabled setting. If true, servers,
clients, Consul DNS and the Consul UI will be enabled. Each component can override
this default via its component-specific "enabled" config. If false, no components
will be installed by default and per-component opt-in is required, such as by
setting [`server.enabled`](#v-server-enabled) to true.
- `name` ((#v-global-name)) (`string: null`) - Set the prefix used for all resources in the Helm chart. If not set, the prefix will be `<helm release name>-consul`.
- `domain` ((#v-global-domain)) (`string: "consul"`) - The domain Consul will answer DNS queries for (see [-domain](/docs/agent/options#_domain)) and the domain services synced from
Consul into Kubernetes will have, e.g. `service-name.service.consul`.
- `image` ((#v-global-image)) (`string: "consul:<latest version>"`) - The name (and tag) of the Consul Docker image for clients and servers. This can be overridden per component. This should be pinned to a specific version tag, otherwise you may inadvertently upgrade your Consul version.
Examples:
```yaml
# Consul 1.5.0
image: "consul:1.5.0"
# Consul Enterprise 1.5.0
image: "hashicorp/consul-enterprise:1.5.0-ent"
```
- `imageK8S` ((#v-global-imagek8s)) (`string: "hashicorp/consul-k8s:<latest version>"`) - The name (and tag) of the [consul-k8s](https://github.com/hashicorp/consul-k8s) Docker image that is used for functionality such the catalog sync. This can be overridden per component.
Note: support for the catalog sync's liveness and readiness probes was added to consul-k8s 0.6.0. If using an older consul-k8s version, you may need to remove these checks to make sync work. If using mesh gateways and global.acls.manageSystemACLs then must be >= 0.9.0.
- `datacenter` ((#v-global-datacenter)) (`string: "dc1"`) - The name of the datacenter that the agents should
register as. This can't be changed once the Consul cluster is up and running since Consul
doesn't support an automatic way to change this value currently: [https://github.com/hashicorp/consul/issues/1858](https://github.com/hashicorp/consul/issues/1858).
- `enablePodSecurityPolicies` ((#v-global-enablepodsecuritypolicies)) (`boolean: false`) - Controls whether pod
security policies are created for the Consul components created by this chart. See [https://kubernetes.io/docs/concepts/policy/pod-security-policy/](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
- `gossipEncryption` ((#v-global-gossipencryption)) - Configures which Kubernetes secret to retrieve Consul's
- `manageSystemACLs` ((#v-global-acls-managesystemacls)) (`boolean: false`) - If true, the Helm chart will automatically manage ACL tokens and policies for all Consul and consul-k8s components.
This requires servers to be running inside Kubernetes. Additionally requires Consul >= 1.4 and consul-k8s >= 0.14.0.
- `bootstrapToken` ((#v-global-acls-bootstraptoken)) - A Kubernetes secret containing the bootstrap token to use for
creating policies and tokens for all Consul and consul-k8s components.
If set, we will skip ACL bootstrapping of the servers and will only initialize ACLs for the Consul clients and consul-k8s system components.
Requires consul-k8s >= 0.14.0.
- `secretName` ((#v-global-acls-bootstraptoken-secretname)) (`string: null`) - The name of the Kubernetes secret.
- `secretKey` ((#v-global-acls-bootstraptoken-secretkey)) (`string: null`) - The key of the Kubernetes secret.
- `createReplicationToken` ((#v-global-acls-createreplicationtoken)) (`boolean: false`) - If true, an ACL token will be created that can be used in secondary
datacenters for replication. This should only be set to true in the
primary datacenter since the replication token must be created from that
datacenter.
In secondary datacenters, the secret needs to be imported from the primary
datacenter and referenced via `global.acls.replicationToken`.
Requires consul-k8s >= 0.13.0.
- `replicationToken` ((#v-global-acls-replicationtoken)) - replicationToken references a secret containing the replication ACL token.
This token will be used by secondary datacenters to perform ACL replication
and create ACL tokens and policies.
This value is ignored if `bootstrapToken` is also set.
Requires consul-k8s >= 0.13.0.
- `secretName` ((#v-global-acls-replicationtoken-secretname)) (`string: null`) - The name of the Kubernetes secret.
- `secretKey` ((#v-global-acls-replicationtoken-secretkey)) (`string: null`) - The key of the Kubernetes secret.
- `enabled` ((#v-global-federation-enabled)) (`boolean: false`) - **Experimental: Currently this is only available in Consul 1.8.0.**
If enabled, this datacenter will be federation-capable. Only federation
via mesh gateways is supported.
Mesh gateways and servers will be configured to allow federation.
Requires `global.tls.enabled`, `meshGateway.enabled` and `connectInject.enabled`
to be true.
- `createFederationSecret` ((#v-global-federation-createfederationsecret)) (`boolean: false`) - If true, the chart will create a Kubernetes secret that can be imported
into secondary datacenters so they can federate with this datacenter. The
secret contains all the information secondary datacenters need to contact
and authenticate with this datacenter. This should only be set to true
- `tls` ((#v-global-tls)) - Enables TLS [encryption](https://learn.hashicorp.com/consul/security-networking/agent-encryption) across the cluster to verify authenticity of the Consul servers and clients. Requires Consul v1.4.1+ and consul-k8s v0.16.2+
- `serverAdditionalDNSSANs` ((#v-global-serveradditionaldnsssans)) (`array<string>: []`) - A list of additional DNS names to set as Subject Alternative Names (SANs) in the server certificate. This is useful when you need to access the Consul server(s) externally, for example, if you're using the UI.
- `serverAdditionalIPSANs` ((#v-global-serveradditionalipsans)) (`array<string>: []`) - A list of additional IP addresses to set as Subject Alternative Names (SANs) in the server certificate. This is useful when you need to access the Consul server(s) externally, for example, if you're using the UI.
- `verify` ((#v-global-verify)) (`boolean: true`) - If true, `verify_outgoing`, `verify_server_hostname`,
and `verify_incoming_rpc` will be set to `true` for Consul servers and clients.
Set this to false to incrementally roll out TLS on an existing Consul cluster.
- `bootstrapExpect` ((#v-server-bootstrapexpect)) (`integer: 3`) - For new clusters, this is the
number of servers to wait for before performing the initial leader election and bootstrap of the cluster. This must be less than or equal to `server.replicas`. This value is only used
Kubernetes secret that you have created that contains your enterprise license. It is required if you are using an enterprise binary. Defining it here applies it to your cluster once a leader
- `connect` ((#v-server-connect)) (`boolean: true`) - This will enable/disable [Connect](/docs/connect). Setting this to true _will not_ automatically secure pod communication, this
- `updatePartition` ((#v-server-updatepartition)) (`integer: 0`) - This value is used to carefully
control a rolling update of Consul server agents. This value specifies the [partition](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#partitions)
- `disruptionBudget` ((#v-server-disruptionbudget)) - This configures the [PodDisruptionBudget](https://kubernetes.io/docs/tasks/run-application/configure-pdb/) for the server cluster.
- `enabled` ((#v-server-disruptionbudget-enabled)) (`boolean: true`) - This will enable/disable
registering a PodDisruptionBudget for the server cluster. If this is enabled, it will only register the budget so long as the server cluster is enabled.
- `maxUnavailable` ((#v-server-disruptionbudget-maxunavailable)) (`integer: null`) - The maximum
number of unavailable pods. By default, this will be automatically computed based on the `server.replicas` value to be `(n/2)-1`. If you need to set this to `0`, you will need to add a `--set 'server.disruptionBudget.maxUnavailable=0'` flag to the helm chart installation
[configuration](/docs/agent/options) for Consul servers. This will be saved as-is into a ConfigMap that is read by the Consul server agents. This can be used to add additional configuration that isn't directly exposed by the chart.
- `affinity` ((#v-server-affinity)) (`string`) - This value defines the [affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity)

- `priorityClassName` ((#v-server-priorityclassname)) (`string`) - This value references an existing
Kubernetes [priorityClassName](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/#pod-priority) that can be assigned to server pods.
- `join` ((#v-client-join)) (`array<string>: null`) - A list of valid [`-retry-join` values](/docs/agent/options#retry-join). If this is `null` (default), then the clients will attempt to automatically join the server cluster running within Kubernetes. This means that with `server.enabled` set to true, clients will automatically join that cluster. If `server.enabled` is not true, then a value must be specified so the clients can join a valid cluster.
- `dataDirectoryPath` ((#v-client-datadirectorypath)) (`string: null`) - An absolute path to a
directory on the host machine to use as the Consul client data directory. If set to the empty string or null, the Consul agent will store its data in the Pod's local filesystem (which will
Policies _must_ be enabled on your cluster and in this Helm chart (via the global.enablePodSecurityPolicies setting) to prevent other Pods from mounting the same host path and gaining access to all of Consul's data. Consul's data is not encrypted at rest.
- `grpc` ((#v-client-grpc)) (`boolean: true`) - If true, agents will enable their GRPC listener on
port 8502 and expose it to the host. This will use slightly more resources, but is
- `exposeGossipPorts` ((#v-client-exposegossipports)) (`boolean: false`) - If true, the Helm chart
will expose the clients' gossip ports as hostPorts. This is only necessary if pod IPs in the k8s cluster are not directly routable and the Consul servers are outside of the k8s cluster.
for each of the client agents. This should be a multi-line string mapping directly to a Kubernetes
[ResourceRequirements](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.11/#resourcerequirements-v1-core) object. If this isn't specified, then the pods won't request any specific amount of resources.
[configuration](/docs/agent/options) for Consul clients. This will be saved as-is into a ConfigMap that is read by the Consul agents. This can be used to add additional configuration that isn't directly exposed by the chart.
- `extraVolumes` ((#v-client-extravolumes)) (`array: []`) - A list of extra volumes to mount for
client agents. This is useful for bringing in extra data that can be referenced by other configurations at a well known path, such as TLS certificates or Gossip encryption keys. The
- `tolerations` ((#v-client-tolerations)) (`string: ""`) - Toleration Settings for client pods. This
should be a multi-line string matching the Toleration array in a Pod spec. The example below will allow client pods to run on every node regardless of taints.
- `nodeSelector` ((#v-client-nodeselector)) (`string: null`) - Labels for client pod assignment,
formatted as a multi-line string. Please see [Kubernetes docs](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#nodeselector) for more details.
- `priorityClassName` ((#v-client-priorityclassname)) (`string: ""`) - This value references an
existing Kubernetes [priorityClassName](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/#pod-priority) that can be assigned to client pods.

- `snapshotAgent` ((#v-client-snapshotagent)) <EnterpriseAlert inline /> - Values for setting up and running [snapshot agents](/docs/commands/snapshot/agent)
manually created to contain the entire config to be used on the snapshot agent. This is the preferred method of configuration since there are usually storage credentials present. Please see [Snapshot agent config](/docs/commands/snapshot/agent#config-file-options) for details.
synced by default. If false, the service must be [annotated](/docs/k8s/service-sync#sync-enable-disable) properly to sync. In either case an annotation can override the default.
- `toConsul` ((#v-synccatalog-toconsul)) (`boolean: true`) - If true, will sync Kubernetes services
to Consul. This can be disabled to have a one-way sync.
- `toK8S` ((#v-synccatalog-tok8s)) (`boolean: true`) - If true, will sync Consul services to
Kubernetes. This can be disabled to have a one-way sync.
- `k8sPrefix` ((#v-synccatalog-k8sprefix)) (`string: ""`) - A prefix to prepend to all services
registered in Kubernetes from Consul. This defaults to `""` where no prefix is prepended; Consul services are synced with the same name to Kubernetes. (Consul -> Kubernetes sync only)
- `k8sAllowNamespaces` ((#v-synccatalog-k8sallownamespaces)) (`[]string: ["*"]`) - list of k8s
namespaces to sync the k8s services from. If a k8s namespace is not included in this list or is listed in `k8sDenyNamespaces`, services in that k8s namespace will not be synced even if they are explicitly annotated. Use `["*"]` to automatically allow all k8s namespaces. For example,
- `k8sDenyNamespaces` ((#v-synccatalog-k8sdenynamespaces)) (`[]string: ["kube-system", "kube-public"]` - list of k8s namespaces that should not have their services synced. This list takes precedence over `k8sAllowNamespaces`. `*` is not supported because then nothing would be allowed to sync. Requires consul-k8s v0.12+.
For example, if `k8sAllowNamespaces` is `["*"]` and `k8sDenyNamespaces` is `["namespace1", "namespace2"]`, then all k8s namespaces besides `namespace1` and `namespace2` will be synced.
- `k8sSourceNamespace` ((#v-synccatalog-k8ssourcenamespace)) (`string: ""`) - **[DEPRECATED] Use
`k8sAllowNamespaces` and `k8sDenyNamespaces` instead.** `k8sSourceNamespace` is the Kubernetes namespace to watch for service changes and sync to Consul. If this is not set then it will default to all namespaces.

- `consulDestinationNamespace` ((#v-synccatalog-consulnamespaces-consuldestinationnamespace)) (`string: "default"`) - Name of the Consul namespace to register all k8s
services to be registered into a Consul namespace of the same name as their k8s namespace, optionally prefixed if `mirroringK8SPrefix` is set below. If the Consul namespace does not already exist, it will be created. Turning this on overrides the `consulDestinationNamespace` setting. `addK8SNamespaceSuffix` may no longer be needed if enabling this option.
- `mirroringK8SPrefix` ((#v-synccatalog-consulnamespaces-mirroringk8sprefix)) (`string: ""`) - If
`mirroringK8S` is set to true, `mirroringK8SPrefix` allows each Consul namespace to be given a prefix. For example, if `mirroringK8SPrefix` is set to `"k8s-"`, a service in the k8s `staging` namespace will be registered into the `k8s-staging` Consul namespace.
- `addK8SNamespaceSuffix` ((#v-synccatalog-addk8snamespacesuffix)) (`boolean: true`) - If true, sync catalog will append Kubernetes namespace suffix to each service name synced to Consul, separated by a dash. For example, for a service `foo` in the `default` namespace, the sync process will create a Consul service named `foo-default`. Set this flag to true to avoid registering services with the same name but in different namespaces as instances for the same Consul service. Namespace suffix is not added if `annotationServiceName` is provided.
- `consulPrefix` ((#v-synccatalog-consulPrefix)) (`string: ""`) - A prefix to prepend to all services registered in Consul from Kubernetes. This defaults to `""` where no prefix is prepended.

- `k8sTag` ((#v-synccatalog-k8stag)) (`string: null`) - An optional tag that is applied to all of the Kubernetes services that are synced into Consul. If nothing is set, this defaults to "k8s". (Kubernetes -> Consul sync only)
- `syncClusterIPServices` ((#v-synccatalog-syncclusteripservices)) (`boolean: true`) - If true, will
sync Kubernetes ClusterIP services to Consul. This can be disabled to have the sync ignore ClusterIP-type services.
- `nodePortSyncType` ((#v-synccatalog-nodeportsynctype)) (`string: ExternalFirst`) - Configures the
type of syncing that happens for NodePort services. The only valid options are: `ExternalOnly`, `InternalOnly`, and `ExternalFirst`. `ExternalOnly` will only use a node's ExternalIP address
- `secretName` ((#v-synccatalog-acl-sync-token-secret-name)) `(string: null)` - The name of the Kubernetes secret. This defaults to null.
- `secretKey` ((#v-synccatalog-acl-sync-token-secret-key)) `(string: null)` - The key for the Kubernetes secret. This defaults to null.
- `nodeSelector` ((#v-synccatalog-nodeselector)) (`string: null`) - This value defines

image (including any tag) for Consul. This is used for proxy service registration, Envoy configuration, etc.
- `imageEnvoy` ((#v-connectinject-imageEnvoy)) (`string: ""`) - The name of the Docker image (including any tag) for the Envoy sidecar. `envoy` must be on the executable path within this image. This Envoy version must be compatible with the Consul version used by the injector. If not specified this defaults to letting the injector choose the Envoy image. Check [supported Envoy versions](/docs/connect/proxies/envoy.html#supported-versions) to ensure the version you are using is compatible with Consul.
- `namespaceSelector` ((#v-connectinject-namespaceselector)) (`string: ""`) - A [selector](https://
- `k8sAllowNamespaces` ((#v-connectinject-k8sallownamespaces)) - list of k8s namespaces to allow
Connect sidecar injection in. If a k8s namespace is not included or is listed in `k8sDenyNamespaces`, pods in that k8s namespace will not be injected even if they are explicitly annotated. Use `["*"]` to automatically allow all k8s namespaces.
For example, `["namespace1", "namespace2"]` will only allow pods in the k8s namespaces `namespace1` and `namespace2` to have Connect sidecars injected and registered with Consul. All other k8s namespaces will be ignored.
Note: `k8sDenyNamespaces` takes precedence over values defined here and `namespaceSelector` takes precedence over both since it is applied first. `kube-system` and `kube-public` are never injected, even if included here. Requires consul-k8s v0.12+
- `k8sDenyNamespaces` ((#v-connectinject-k8sdenynamespaces)) - list of k8s namespaces that should not
allow Connect sidecar injection. This list takes precedence over `k8sAllowNamespaces`. `*` is not supported because then nothing would be allowed to be injected.
For example, if `k8sAllowNamespaces` is `["*"]` and `k8sDenyNamespaces` is `["namespace1", "namespace2"]`, then all k8s namespaces besides `namespace1` and `namespace2` will be injected.
Note: `namespaceSelector` takes precedence over this since it is applied first. `kube-system` and `kube-public` are never injected. Requires consul-k8s v0.12+.
the connect injector's interaction with Consul namespaces (requires consul-ent v1.7+ and consul-k8s v0.12+). Also, `global.enableConsulNamespaces` must be true.
(`string: "default"`) - Name of the Consul namespace to register all k8s services into. If the Consul namespace does not already exist, it will be created.
services to be registered into a Consul namespace of the same name as their k8s namespace, optionally prefixed if `mirroringK8SPrefix` is set below. If the Consul namespace does not already exist, it will be created. Turning this on overrides the `consulDestinationNamespace` setting.
- `mirroringK8SPrefix` ((#v-connectinject-consulnamespaces-mirroringk8sprefix)) (`string: ""`) - If
`mirroringK8S` is set to true, `mirroringK8SPrefix` allows each Consul namespace to be given a prefix. For example, if `mirroringK8SPrefix` is set to `"k8s-"`, a service in the k8s `staging` namespace will be registered into the `k8s-staging` Consul namespace.
- `certs` ((#v-connectinject-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.
- `secretName` ((#v-connectinject-certs-secretname)) (`string: null`) - 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` ((#v-connectinject-cabundle)) (`string: ""`) - The PEM-encoded CA public certificate
bundle for the TLS certificate served by the injector. This must be specified as a string
- `aclInjectToken` ((#v-connectinject-aclinjecttoken)) - Refers to a Kubernetes secret that you have created that contains an ACL token for your Consul cluster which allows the Connect injector the correct permissions. This is only needed if Consul namespaces and ACLs are enabled on the Consul cluster and you are not setting `global.acls.manageSystemACLs` to `true`. This token needs to have `operator = "write"` privileges so that it can create namespaces.
- `secretName` ((#v-connectinject-aclinjecttoken-secretname)) `(string: null)` - The name of the Kubernetes secret.
- `secretKey` ((#v-connectinject-aclinjecttoken-secretkey)) `(string: null)` - The key within the Kubernetes secret that holds the acl token.
defined, this value will be used as the default protocol type for all services registered with the central configuration. This can be overridden by using the [protocol annotation](/docs/k8s/connect#consul-hashicorp-com-connect-service-protocol) directly on any pod spec.
- `enabled` ((#v-meshgateway-enabled)) (`boolean: true`) - If mesh gateways are enabled, a Deployment will be created that runs
gateways and Consul Connect will be configured to use gateways.
See [mesh gateway docs](https://www.consul.io/docs/connect/mesh_gateway.html).
Requirements: Consul 1.6.0+ and consul-k8s 0.15.0+ if using
`global.acls.manageSystemACLs`.
- `globalMode` ((#v-meshgateway-globalmode)) (`string: "local"`) - Globally configure which mode the gateway should run in.
Can be set to either `"remote"`, `"local"`, `"none"` or `""` or `null`.
See [mesh gateway modes of operation](https://consul.io/docs/connect/mesh_gateway.html#modes-of-operation) for
a description of each mode.
If set to anything other than `""` or `null`, `connectInject.centralConfig.enabled`
should be set to true so that the global config will actually be used.
If set to the empty string, no global default will be set and the gateway mode
will need to be set individually for each service.
- `replicas` ((#v-meshgateway-replicas)) (`int: 2`) - Number of replicas for the Deployment.
- `wanAddress` ((#v-meshgateway-wanaddress)) - What gets registered as WAN (wide area network) address for the gateway.
- `source` ((#v-meshgateway-wanaddress-source)) (`string: "Service"`) - source configures where to retrieve the WAN address (and possibly port)
for the mesh gateway from.
Can be set to either: `Service`, `NodeIP`, `NodeName` or `Static`. See the behavior of each below:
* `Service` - Determine the address based on the service type.
If `service.type=LoadBalancer` use the external IP or hostname of
the service. Use the port set by `service.port`.
If `service.type=NodePort` use the Node IP. The port will be set to
`service.nodePort` so `service.nodePort` cannot be null.
If `service.type=ClusterIP` use the ClusterIP. The port will be set to
`service.port`.
`service.type=ExternalName` is not supported.
* `NodeIP` - The node IP as provided by the Kubernetes downward API.
* `NodeName` - The name of the node as provided by the Kubernetes downward
API. This is useful if the node names are DNS entries that
are routable from other datacenters.
* `Static` - Use the address hardcoded in `meshGateway.wanAddress.static`.
- `port` ((#v-meshgateway-wanaddress-port)) (`int: 443`) - Port that gets registered for WAN traffic.
If source is set to "Service" then this setting will have no effect.
See the documentation for `source` as to which port will be used in that
case.
- `static` ((#v-meshgateway-wanaddress-static)) (`string: ""`) - If source is set to "Static" then this value will be used as the WAN
address of the mesh gateways. This is useful if you've configured a
DNS entry to point to your mesh gateways.
- `service` ((#v-meshgateway-service)) - The service option configures the Service that fronts the Gateway Deployment.
- `enabled` ((#v-meshgateway-service-enabled)) (`bool: true`) - Whether to create a Service or not.

The `targetPort` will be set to `meshGateway.containerPort`.
- `nodePort` ((#v-meshgateway-service-nodeport)) (`int: null`) - Optionally hardcode the `nodePort` of the service if using a NodePort service.
If not set and using a NodePort service, Kubernetes will automatically assign a port.

```yaml
annotations: |
"sample/annotation1": "foo"
"sample/annotation2": "bar"

- `dnsPolicy` ((#v-meshgateway-dnspolicy)) (`string: null`) - `dnsPolicy` to use.
- `consulServiceName` ((#v-meshgateway-consulservicename)) (`string: "mesh-gateway"`) - Consul service name for the mesh gateways.
Cannot be set to anything other than `"mesh-gateway"` if `global.acls.manageSystemACLs` is true since the ACL token
generated is only for the name "mesh-gateway".
- `containerPort` ((#v-meshgateway-containerPort)) (`int: 8443`) - Port that the gateway will run on inside the container.
- `hostPort` ((#v-meshgateway-hostport)) (`int: null`) - Optional `hostPort` for the gateway to be exposed on.
This can be used with `wanAddress.port` and `wanAddress.useNodeIP`
to expose the gateways directly from the node.
If `hostNetwork=true`, this must be `null` or set to the same port as
`containerPort`.
**NOTE:** Cannot set to 8500 or 8502 because those are reserved for the Consul
agent.
- `resources` ((#v-meshgateway-resources)) (`string`) - Resources for gateway pods. See values file for default.
- `affinity` ((#v-meshgateway-affinity)) (`string`) - Affinity setting for gateway pods. See values file for default.
