Install PaletteAI on Kubernetes
Use this guide to install PaletteAI on a self-managed Kubernetes cluster where you control the API server configuration. The deployment uses the hub-as-spoke pattern with Zot as the Open Container Initiative (OCI) registry. Use this guide if you are installing PaletteAI on:
-
Self-managed clusters except AWS EC2-based clusters, such as kubeadm, k3s, and RKE
-
Self-hosted Kubernetes deployments
-
Edge environments
-
Any cluster where you can configure the Kubernetes API server to trust Dex as an OIDC provider
If you are installing PaletteAI on AWS or GKE, use a platform-specific guide instead:
Prerequisites
-
Use a Kubernetes cluster as the PaletteAI hub.
-
Access to the hub cluster using the built-in Kubernetes
cluster-adminClusterRole. -
Minimum Kubernetes versions
Cluster Type Kubernetes Version Hub >= 1.31.0 Spoke >= 1.31.0 -
Minimum resource requests
Cluster Type CPU Memory Storage Hub 3388m 2732 Mi 10Gi Spoke 1216m 972 Mi 10Gi -
Ensure the hub cluster can reach the public AWS Elastic Container Registry (ECR) that hosts the
muralandmural-crdscharts. -
Access to the hub cluster
kubeconfigfile. -
Install Flux controllers on the hub cluster if you plan to use the recommended Flux-managed workflow.
-
Install the following tools on the machine you use to install or upgrade PaletteAI:
-
Configure the hub cluster Kubernetes API server to trust Dex as an identity provider. PaletteAI deploys Dex as part of the installation. This requirement applies only to the hub cluster, not to spoke clusters. For details, refer to Configure Kubernetes API Server to Trust OpenID Connect (OIDC) Provider.
- Your hub cluster must be able to provision load balancer services. For self-hosted or bare-metal clusters, this requires a load balancer implementation such as MetalLB. For cloud-hosted clusters, ensure the appropriate cloud controller manager is configured.
Enablement
-
-
Download the latest Helm chart values file. This example uses
curl.curl --output values.yaml --silent https://docs.palette-ai.com/resources/assets/hosted/helm/values.yaml -
Open the Helm chart values file in a text editor of your choice and complete the following sections. This example uses
vi.vi values.yaml
Global
-
-
Use the
globalsection to configure overarching settings for the PaletteAI deployment. Review and modify the following values as necessary.-
Set
global.dns.domainto the primary domain for the deployment. Do not include a protocol. For example, useexample.org, nothttps://example.org.global:
dns:
domain: 'example.acme.org' -
In
global.auditLogging.basicAuth, change the defaultusernameandpasswordfor audit logging. These credentials secure the Alertmanager instance that receives audit events. You reuse them when you configure the Base64-encodedAuthorizationheader in thealertmanagersection.global:
auditLogging:
basicAuth:
username: '<your-username>'
password: '<your-password>'Refer to Audit Logging to learn more about configuring audit logging, querying audit events, and forwarding logs to long-term storage.
-
Configure the metrics collection settings. Provide an existing, external Prometheus server that is reachable from the hub cluster and every spoke cluster. Spoke clusters use Prometheus agents to ship metrics to the server via
remote_write.Set
global.metrics.prometheusBaseUrlto the external Prometheus server URL (for example,https://your-external-prometheus:9090). Include only the protocol, host, and port — do not include any API paths.global:
metrics:
prometheusBaseUrl: 'https://your-external-prometheus:9090'
timeout: '5s'
scrapeInterval: '15s'
agentType: 'prometheus-agent-minimal'
username: ''
password: ''By default,
global.metrics.agentTypeis set toprometheus-agent-minimal. The minimal agent configuration only collects spoke cluster CPU and GPU utilization metrics. You may changeglobal.metrics.agentTypetoprometheus-agentto ship all node-exporter and dcgm-exporter metrics from spoke clusters for comprehensive observability.If your Prometheus server requires basic authentication, configure the
usernameandpasswordfields. Leave these fields blank if authentication is not required.Refer to Configure Prometheus Agent Monitoring for guidance on agent types, Prometheus and Grafana prerequisites, and GPU metrics.
tipIf you need to set up a Prometheus server, you may find the Deploy Monitoring Stack guide helpful.

Navigate to the
alertmanagersection. Update credentials for thealertmanagerinstance based on the credentials you configured in theglobalsection.You must provide a Base64-encoded string for the
Authorizationheader. Use the interactive encoder to generate your Base64-encoded string and copy the value to the clipboard.Base64 Encoded String:Alternatively, generate the Base64-encoded string using the following command. Replace
usernameandpasswordwith the username and password you configured in theglobalsection.echo -n "username:password" | base64The following example shows the

Canvas
-
Canvas controls the user interface. Review and modify the following values as necessary.
-
To configure the ingress for Canvas, set
canvas.ingress.enabledtotrue. Setcanvas.ingress.domainto your domain name. Omit thehttp://orhttps://prefix.canvas:
ingress:
enabled: true
annotations: {}
ingressClassName: nginx
domain: replace.with.your.domain # No HTTP/HTTPS prefix.
matchAllHosts: false
tls: []
paths:
- path: /ai
pathType: ImplementationSpecific
backend:
service:
name: canvas
port:
number: 2999Set
canvas.enableHTTPtotrueto let the load balancer terminate Transport Layer Security (TLS). Leavecanvas.ingress.tlsempty.canvas:
enableHTTP: true -
The last portion of the Canvas configuration is the OIDC configuration. If you defer configuring OIDC for Dex, you may do the same for Canvas and configure it later.
In the
canvas.oidcsection, enter a unique string for thesessionSecret. ForredirectURL, replace<your-domain>with your domain. Do not remove the/ai/callbackpath.canvas:
oidc:
sessionSecret: '<your-session-secret>'
sessionDir: '/app/sessions'
issuerK8sService: 'https://dex.mural-system.svc.cluster.local:5554/dex'
skipSSLCertificateVerification: true
redirectURL: 'https://<your-domain>/ai/callback'If you did not configure your Kubernetes cluster to trust Dex as an OIDC provider, then you must configure the
canvas.impersonationProxysection to enable user impersonation.The example below shows how to configure the local Dex user
admin@example.comto be mapped to an example Kubernetes groupadmin. Refer to our Configure User Impersonation guide to learn more about how to configure user impersonation for OIDC groups and other use cases.Example user impersonation setupcanvas:
impersonationProxy:
enabled: true
userMode: 'passthrough'
groupsMode: 'map'
userMap: {}
groupMap: {}
dexGroupMap:

Dex
-
-
Dex authenticates users to PaletteAI through SSO. You can configure Dex to connect to an upstream OIDC provider or to a local user database. For this installation, you will configure Dex to connect to an upstream OIDC provider. If you want to configure an OIDC provider later, you can do so; however, Dex still requires some basic configuration.
-
Set
dex.config.issuerto your domain. Do not remove the/dexpath.dex:
config:
issuer: 'https://<your-domain>/dex' -
This next part may be deferred for later, but we strongly recommend configuring at least one connector. Set the
dex.config.connectorsto the connectors you want to use. The Dex documentation has examples for each of the connectors.Below is an example of an OIDC connector that connects to AWS Cognito. The
oidctype can be used for any OIDC provider that does not have a native Dex connector. Different OIDC providers may require different configurations.Example AWS Cognito configurationdex:
config:
connectors:
- type: oidc
id: aws
name: AWS Cognito
config:
issuer: https://cognito-idp.us-east-1.amazonaws.com/us-east-1_xxxxxx
clientID: xxxxxxxxxxxxxxx
clientSecret: xxxxxxxxxxxxxxxxx
redirectURI: https://<your-domain>/dex/callback # Dex callback URL for the authorization code flow; redirects to the application callback URL
getUserInfo: true
userNameKey: email
insecureSkipEmailVerified: true
insecureEnableGroups: true
scopes:
- openid
- email
- profile
promptType: consent
claimMapping:
groups: groups -
Proceed to the
dex.config.staticClientssection. Replace<your-client-secret>with a unique secret value and<your-domain>with your domain. Do not remove the/ai/callbackpath for themuralclient.dex:
config:
staticClients:
- id: mural
redirectURIs:
- 'https://<your-domain>/ai/callback'
name: 'mural'
secret: '<your-client-secret>'
public: false
trustedPeers:
- kubernetes
- id: kubernetes
redirectURIs:
- 'https://<your-domain>'
name: kubernetes
secret: '<your-client-secret>'
public: false
trustedPeers:
- mural -
Next, configure the
dex.config.staticPasswordssection. We strongly recommend changing the default user (admin) and password (password) to strong values. The following example is the default user and password in bcrypt format. Remember to use a bcrypt hash generator to generate the password hash. TheuserIDcan be any unique string.warningIf you did not configure any OIDC connectors, you must configure at least one static user, which is used to access the PaletteAI UI. Static Dex users automatically inherit admin privileges through the service account. Dex does not support groups for local static users. To use groups for local static users, you must use the User Impersonation feature.
dex:
config:
staticPasswords:
- email: 'admin@example.com'
hash: '$2a$12$Ot2dJ0pmdIC2oXUDW/Ez1OIfhkSzLZIbsumsxkByuU3CUr02DtiC.'
username: 'admin'
userID: '08a8684b-db88-4b73-90a9-3cd1661f5466' -
Configure the
dex.ingresssection to expose Dex. Forhost, replace<your-domain>with your domain. Do not change theclassNameor thepath. Because Transport Layer Security (TLS) is terminated at the load balancer, thetlssection is empty.dex:
ingress:
enabled: true
className: 'nginx'

Create a DNS record pointing your
canvas.ingress.domainconfigured invalues.yamlto the load balancer created by the ingress-nginx controller. Use an A record for IP addresses or a CNAME/alias record for hostnames, depending on your DNS provider's capabilities.
You have now deployed PaletteAI on your Kubernetes cluster. The cluster is configured to trust Dex as an identity provider. If you configured Dex with an OIDC connector, you can now log in to PaletteAI by using your identity provider (IdP). You can also use the default Dex local user.
If you need to update PaletteAI later, review Helm Chart Configuration and then follow Upgrade PaletteAI. For Flux-managed installations, update the mural HelmRelease or the relevant OCIRepository resource and let Flux reconcile the change. For manual Helm installations, follow Upgrade Manually and apply mural-crds out of band before mural.
Validate
Take the following steps to verify that PaletteAI is deployed and configured correctly.
-
Open a browser and navigate to the domain URL you configured for PaletteAI.
-
Log in with the default username and password. If you configured Dex with an OIDC connector, log in with your identity provider.
Next Steps
Once you have installed PaletteAI, integrate Palette with PaletteAI by configuring the Settings resource. This resource requires a Palette tenant, project, and API key so PaletteAI can communicate with Palette and deploy AI/ML applications and models to the correct location.
Proceed to the Integrate with Palette guide to learn how to prepare your Palette environment.
