Tekton Dashboard - Installer

This guide explains how to use the installer to build, install or uninstall the Dashboard using the installer script.

It covers the following topics:

Before you begin

The installer script makes it easy to install the Tekton Dashboard by allowing command line options to customize the manifests at install time.

For example, this allows the installer script to ensure that the deployed Dashboard and the RBAC permissions are consistent.

Notes:

  • These instructions don't cover the frontend, make sure you build the frontend first.

  • The installer script uses ko. Before it can build and push the dashboard docker image you will have to define the KO_DOCKER_REPO environment variable.

    You can use a remote repository like Docker Hub or set it to ko.local to avoid dealing with auth / network issues for an external repository. See ko usage for more info.

    export KO_DOCKER_REPO='ko.local'
# or use an external repository
# export KO_DOCKER_REPO='docker.io/myusername'

Help command

The help command shows the supported commands and options by the script:

./scripts/installer help

It will produce output similar to the following:

Global command syntax:
        installer COMMAND [OPTIONS]

Accepted commands:
        help|h                                  Prints this help

        [--namespace <namespace>]               Will override install namespace
        [--nightly]                             Will download manifests from the nightly releases channel
        [--output <file>]                       Will output built manifests in the file instead of in the console
        [--pipelines-namespace <namespace>]     Override the namespace where Tekton Pipelines is installed (defaults to Dashboard install namespace)
        [--platform <platform>]                 Override the platform to build for
        [--read-write]                          Will build manifests for a read/write deployment
        [--stream-logs false]                   Will disable log streaming and use polling instead
        [--tag <tag>]                           Tag used for the image produced by ko
        [--tenant-namespaces <namespaces>]      Will limit the visibility to the specified comma-separated namespaces only
        [--triggers-namespace <namespace>]      Override the namespace where Tekton Triggers is installed (defaults to Dashboard install namespace)
        [--version <version>]                   Will download manifests for specified version or build everything using kustomize/ko

Install command

The install command is used to install the Tekton Dashboard in a cluster. It supports both Kubernetes and OpenShift.

Examples below illustrate the main install options:

Installing on Kubernetes

To install the Tekton Dashboard on Kubernetes, using the default options, run the command:

./scripts/installer install

This will install the Dashboard in the tekton-pipelines namespace and assumes that Tekton Pipelines and Triggers are also installed in the tekton-pipelines namespace.

OpenShift with Tekton Pipelines and Triggers installed by OpenShift Pipelines Operator

To install the Tekton Dashboard on OpenShift after installing Tekton Pipelines and Triggers using OpenShift Pipelines Operator, run the command:

./scripts/installer install --namespace openshift-pipelines

Alternatively, take one of the official release manifests and replace any reference to the tekton-pipelines namespace with openshift-pipelines for the same result.

Installing in a custom namespace

You can install the Dashboard in the namespace of your choice, this works whatever the platform (Kubernetes / OpenShift) and install method (OpenShift Pipelines Operator / manifests).

To tell the installer script the target namespace of your choice, add the --namespace option:

CUSTOM_NAMESPACE=my-namespace

./scripts/installer install --namespace $CUSTOM_NAMESPACE

Read/write install

To install the Dashboard add the --read-write option when calling the installer script:

./scripts/installer install --read-write

Installing for limited namespace visibility

Limited namespace visibility restricts the Tekton Dashboard actions scope and resources that can be seen to a subset of namespaces in the cluster.

To install for limited namespace visibility run the following command:

TENANT_NAMESPACES=my-namespace1,my-namespace2

./scripts/installer install --tenant-namespaces $TENANT_NAMESPACES

Install ingress

The installer script can create an ingress for your Dashboard service, to enable ingress creation add --ingress-url and optionally --ingress-secret if the ingress needs TLS support.

./scripts/installer install --ingress-url my-dashboard.my-domain.com --ingress-secret my-tls-certificate

Uninstall command

To uninstall the Dashboard, use the uninstall instead of the install command.

./scripts/installer uninstall

Build command

The installer script can be used to build the Dashboard docker image and the YAML manifests (taking care of command line options) by using the build command when calling the script:

./scripts/installer build

This will NOT deploy the resulting manifest in the target cluster but will build and push the Dashboard docker image to whichever docker repo was configured for ko to work with and will display the YAML manifests in the console output.

The build command is useful when you want to ensure everything builds correctly without altering the current deployment. It can help verifying the generated manifests are correct when a change was made in the base or overlays used by kustomize too.

Platform support

Official Dashboard releases since v0.12.0 provide multi-platform images supporting the following:

  • linux/amd64
  • linux/arm
  • linux/arm64
  • linux/ppc64le
  • linux/s390x

The installer script's build and install commands will build an image for linux/amd64 by default. To override the platform in cases where the target cluster is running on a different architecture, add --platform <platform> where <platform> is a value from the list of supported values, for example:

./scripts/installer install --platform linux/arm

or build a multi-platform image by specifying all or a comma-separated list of supported platforms:

./scripts/installer install --platform all

This behaviour can also be controlled using the GOOS and GOARCH environment variables. See the ko documentation for further details.
