This topic tells you how to install a multicluster topology for your Tanzu Application Platform (commonly known as TAP).
Before installing multicluster Tanzu Application Platform profiles, you must meet the following prerequisites:
The installation order is flexible given the ability to update the installation with a modified values file using the tanzu package installed update
command. The following is an example of the order of operations to be used:
Update the View cluster’s installation values file with the previous information and run the following command to pass the updated config values to Tanzu Developer Portal:
tanzu package installed update tap -p tap.tanzu.vmware.com -v TAP-VERSION --values-file tap-values.yaml -n tap-install
Where TAP-VERSION
is the Tanzu Application Platform version you’ve installed.
Install the View profile cluster first, because some components must exist before installing the Run clusters. For example, the Application Live View back end must be present before installing the Run clusters. For more information about profiles, see About Tanzu Application Platform package profiles.
To install the View cluster:
https://tap-gui.INGRESS-DOMAIN
, where INGRESS-DOMAIN
is the DNS domain you set in shared.ingress_domain
which points to the shared Contour installation in the tanzu-system-ingress
namespace with the service envoy
.To install the Build profile cluster, follow the steps described in Installing the Tanzu Application Platform package and profiles by using a reduced values file as shown in Build profile.
To install the Run profile cluster:
To use Application Live View, set the INGRESS-DOMAIN
for appliveview_connector
to match the value you set on the View profile for the appliveview
in the values file.
NoteThe default configuration of
shared.ingress_domain
points to the local Run cluster, rather than the View cluster, as a result,shared.ingress_domain
must be set explicitly.
To install the Iterate profile cluster, follow the steps described in Install the Tanzu Application Platform package and profiles by using a reduced values file as shown in Iterate profile.
After installing the Build, Run and Iterate clusters, follow the steps in View resources on multiple clusters in Tanzu Developer Portal to:
Service Accounts
that Tanzu Developer Portal uses to read objects from the clusters.These steps create the necessary RBAC elements allowing you to pull the URL and token from the Build, Run and Iterate clusters that allows them come back and add to the View cluster’s values file.
You must add the Build, Run and Iterate clusters to the View cluster for all plug-ins to function as expected.
After setting up the four profiles, you’re ready to run a workload by using the supply chain. See Get started with multicluster Tanzu Application Platform.
