Before installing Wallaroo version, verify that the following hardware and software requirements are met.

Environment Requirements

Environment Hardware Requirements

The following system requirements are required for the minimum settings for running Wallaroo in a Kubernetes cloud cluster.

The following system requirements are required for the minimum settings for running Wallaroo in a Kubernetes cloud cluster.

  • Minimum number of nodes: 4
  • Minimum Number of CPU Cores: 8
  • Minimum RAM per node: 16 GB
  • Minimum Storage: A total of 625 GB of storage will be allocated for the entire cluster based on 5 users with up to four pipelines with five steps per pipeline, with 50 GB allocated per node, including 50 GB specifically for the Jupyter Hub service. Enterprise users who deploy additional pipelines will require an additional 50 GB of storage per lab node deployed.

Wallaroo recommends at least 16 cores total to enable all services. At less than 16 cores, services will have to be disabled to allow basic functionality as detailed in this table.

Note that even when disabling these services, Wallaroo performance may be impacted by the models, pipelines, and data used. The greater the size of the models and steps in a pipeline, the more resources will be required for Wallaroo to operate efficiently. Pipeline resources are set by the pipeline configuration to control how many resources are allocated from the cluster to maintain peak effectiveness for other Wallaroo services. See the following guides for more details.

Cluster Size 8 core16 core32 coreDescription
Inference The Wallaroo inference engine that performs inference requests from deployed pipelines.
Dashboard The graphics user interface for configuring workspaces, deploying pipelines, tracking metrics, and other uses.

Wallaroo Provided Data

Members of the Wallaroo support staff will provide the following information:

  • Wallaroo Container Registration Login: Commands to login to the Wallaroo container registry.
  • Preflight and Support Bundle configuration files: The files preflight.yaml and support-bundle.yaml are used in the commands below to complete the preflight process and generate the support bundle package as needed for troubleshooting needs.
  • Preflight verification command: The commands to verify that the Kubernetes environment meets the requirements for the Wallaroo install.
  • Install Wallaroo Command: Instructions on installations into the Kubernetes environment using Helm through the Wallaroo container registry.

The following steps are used with these command and configuration files to install Wallaroo Enterprise via Helm.

Registration Login

The first step in the Wallaroo installation process via Helm is to connect to the Kubernetes environment that will host the Wallaroo Enterprise instance and login into the Wallaroo container registry through the command provided by the Wallaroo support staff. The command will take the following format, replacing $YOURUSERNAME and $YOURPASSWORD with the respective username and password provided.

helm registry login registry.replicated.com --username $YOURUSERNAME --password $YOURPASSWORD

Preflight Verification

The following instructions detail how to install Wallaroo Enterprise via Helm for Kubernetes cloud environments such as Microsoft Azure, Amazon Web Service, and Google Cloud Platform.

Install Wallaroo

With the preflight checks and prerequisites met, Wallaroo can be installed via Helm through the following process:

  1. Create namespace. By default, the namespace wallaroo is used:

    kubectl create namespace wallaroo
  2. Set the new namespace as the current namespace:

    kubectl config set-context --current --namespace wallaroo
  3. Set the TLS certificate secret in the Kubernetes environment:

    1. Create the certificate and private key. It is recommended to name it after the domain name of your Wallaroo instance. For example: wallaroo.example.com. For production environments, organizations are recommended to use certificates from their certificate authority. Note that the Wallaroo SDK will not connect from an external connection without valid certificates. For more information on using DNS settings and certificates, see the Wallaroo DNS Integration Guide.

    2. Create the Kubernetes secret from the certificates created in the previous step, replacing $TLSCONFIG with the name of the Kubernetes secret. Store the secret name for a the step Configure local values file.

      kubectl create secret tls $TLSCONFIG --cert=$TLSSECRETS --key=$TLSSECRETS

      For example, if $TLSCONFIG is my-tls-secrets with example.com.crt and key example.com.key, then the command would be translated as

      kubectl create secret tls my-tls-secrets --cert=example.com.crt --key=example.com.key
  4. Configure local values file: The default Helm install of Wallaroo contains various default settings. The local values file overwrites values based on the organization needs. The following represents the minimum mandatory values for a Wallaroo installation using certificates and the default LoadBalancer for a cloud Kubernetes cluster. The configuration details below is saved as local-values.yaml for these examples.

    For information on taints and tolerations settings, see the Taints and Tolerations Guide.

    Note the following required settings:

    • domainPrefix and domainSuffix: Used to set the DNS settings for the Wallaroo instance. For more information, see the Wallaroo DNS Integration Guide.
    • replImagePrefix: proxy.replicated.com/proxy/wallaroo/ghcr.io/wallaroolabs: Sets the Replicated installation containe proxy. Set to proxy.replicated.com/proxy/wallaroo/ghcr.io/wallaroolabs unless using a private container registry. Contact a Wallaroo Support representative for details.
    • deploymentStage and custTlsSecretName: These are set for use with the Kubernetes secret created in the previous step. External connections through the Wallaroo SDK require valid certificates.
    • generate_secrets: Secrets for administrative and other users can be generated by the Helm install process, or set manually. This setting scrambles the passwords during installation.
    • apilb: Sets the apilb service options including the following:
      • serviceType: LoadBalancer: Uses the default LoadBalancer setting for the Kubernetes cloud service the Wallaroo instance is installed into. Replace with the specific service connection settings as required.
      • external_inference_endpoints_enabled: true: This setting is required for performing external SDK inferences to a Wallaroo instance. For more information, see the Wallaroo Model Endpoints Guide
domainPrefix: "" # optional if using a DNS Prefix
domainSuffix: {Your Wallaroo DNS Suffix}

deploymentStage: cust
custTlsSecretName: cust-cert-secret

generate_secrets: true

  serviceType: LoadBalancer
  external_inference_endpoints_enabled: true

  clientName: "xx" # Insert the name displayed in the Wallaroo Dashboard

  enabled: true

    size: 25Gi     # Minio model storage disk size. Smaller than 10Gi is not recommended.

  enabled: true

  enabled: true
  1. Install Wallaroo: The Wallaroo support representative will provide the installation command for the Helm install that will use the Wallaroo container registry. This assumes that the preflight checks were successful. This command uses the following format:

    helm install $RELEASE $REGISTRYURL --version $VERSION--values $LOCALVALUES.yaml


    1. $RELEASE: The name of the Helm release. By default, wallaroo.
    2. $REGISTRYURL: The URl for the Wallaroo container registry service.
    3. $VERSION: The version of Wallaroo to install. For this example, 2022.4.0-main-2297.
    4. $LOCALVALUES: The .yaml file containing the local values overrides. For this example, local-values.yaml.

    For example, for the registration wallaroo the command would be:

    helm install wallaroo oci://registry.replicated.com/wallaroo/EE/wallaroo --version 2022.4.0-main-2297 --values local-values.yaml
  2. Verify the Installation: Once the installation is complete, verify the installation with the helm test $RELEASE command. With the settings above, this would be:

    helm test wallaroo

    A successful installation will resemble the following:

    NAME: wallaroo
    LAST DEPLOYED: Wed Dec 21 09:15:23 2022
    NAMESPACE: wallaroo
    STATUS: deployed
    TEST SUITE:     wallaroo-fluent-bit-test-connection
    Last Started:   Wed Dec 21 11:58:34 2022
    Last Completed: Wed Dec 21 11:58:37 2022
    Phase:          Succeeded
    TEST SUITE:     wallaroo-test-connections-hook
    Last Started:   Wed Dec 21 11:58:37 2022
    Last Completed: Wed Dec 21 11:58:41 2022
    Phase:          Succeeded
    TEST SUITE:     wallaroo-test-objects-hook
    Last Started:   Wed Dec 21 11:58:41 2022
    Last Completed: Wed Dec 21 11:58:53 2022
    Phase:          Succeeded

At this point, the installation is complete and can be accessed through the fully qualified domain names set in the installation process above. Verify that the DNS settings are accurate before attempting to connect to the Wallaroo instance. For more information, see the Wallaroo DNS Integration Guide.

To add the initial users if they were not set up through Helm values, see the Wallaroo Enterprise User Management guide.

Troubleshoot Wallaroo

If issues are detected in the Wallaroo instance, a support bundle file is generated using the support-bundle.yaml file provided by the Wallaroo support representative.

This creates a collection of log files, configuration files and other details into a .tar.gz file in the same directory as the command is run from in the format support-bundle-YYYY-MM-DDTHH-MM-SS.tar.gz. This file is submitted to the Wallaroo support team for review.

This support bundle is generated through the following command:

kubectl support-bundle support-bundle.yaml --interactive=false


To uninstall Wallaroo via Helm, use the following command replacing the $RELEASE with the name of the release used to install Wallaroo. By default, this is wallaroo:

helm uninstall wallaroo

It is also recommended to remove the wallaroo namespace after the helm uninstall is complete.

kubectl delete namespace wallaroo
