tanzu apps cluster-supply-chain

This topic tells you about the Tanzu Apps CLI cluster-supply-chain command.

tanzu apps clustersupplychain list

The cluster-supply-chain command provides details about the cluster supply chain installed in the target cluster.

The following aliases are supported:

csc
cluster-supply-chains
clustersupplychains

Run the following command to view more detailed information about the selectors and conditions that must be met for a workload to be selected by a certain supply chain:

tanzu apps cluster-supply-chain get SUPPLYCHAIN-NAME

Default view

The default view displays the name of the supply chain, whether it is ready or not, and its age.

For example:

tanzu apps clustersupplychain list
NAME                 READY   AGE
basic-image-to-url   Ready   11d
source-to-url        Ready   11d

To view details: "tanzu apps cluster-supply-chain get <name>"

tanzu apps cluster-supply-chain get

The tanzu apps cluster-supply-chain get command gets detailed information about the cluster supply chain.

Default view

The default view displays the status of the supply chain, and the selectors that a workload must match so it is taken by that supply chain.

For example:

tanzu apps cluster-supply-chain get source-to-url
---
# source-to-url: Ready
---
Supply Chain Selectors
   TYPE          KEY                                   OPERATOR   VALUE
   expressions   apps.tanzu.vmware.com/workload-type   In         web
   expressions   apps.tanzu.vmware.com/workload-type   In         server
   expressions   apps.tanzu.vmware.com/workload-type   In         worker

This output indicates the attributes a workload needs to be selected by the source-to-url supply chain on the target cluster. For example:

The workload must have the --type flag value of web, server, or worker.
Or, if expressed through workload.yaml, the Workload.metadata.labels label apps.tanzu.vmware.com/workload-type must exist and have a value of web, server , or worker.

Another example is the testing/scanning pipeline, which has the tekton steps for testing and the scanning steps.

# source-test-scan-to-url: Ready

Supply Chain Selectors
   TYPE          KEY                                   OPERATOR   VALUE
   labels        apps.tanzu.vmware.com/has-tests                  true
   expressions   apps.tanzu.vmware.com/workload-type   In         web
   expressions   apps.tanzu.vmware.com/workload-type   In         server
   expressions   apps.tanzu.vmware.com/workload-type   In         worker

In this case, the workload must have both labels apps.tanzu.vmware.com/has-tests: true and apps.tanzu.vmware.com/workload-type set up as web, server, or worker to be selected for the supply chain.
