Reading your workload or deliverable status
Cartographer makes every effort to provide you with useful information in the
status field of your
To see the status of your workload:
kubectl get workload <your-workload-name> -n <your-workload-namespace> -oyaml
Note: We do not recommend
kubectl describe as it makes statuses harder to read.
Take a look at the
status: section for conditions. E.g.:
status: conditions: - type: SupplyChainReady status: True reason: Ready - type: ResourcesSubmitted status: True reason: Ready - type: Ready status: True reason: Ready
Common status conditions
Cartographer conditions follow the Kubernetes API conventions
There is a top level condition of
Type: Ready which can have a
If your workload or deliverable has a
False or a
Unknown condition, inspect the conditions for cause. The
Type: Ready condition’s
Reason will match that of the sub-condition causing the negative status.
Unknown vs. False
A status of
False typically means Cartographer can not proceed until user intervention occurs. These are errors in
A status of
Unknown indicates that resources have not yet resolved. Causes can include network timeouts, long running
processes, and occasionally a misconfiguration that Cartographer cannot itself detect.
This is the most common
status: conditions: - type: SupplyChainReady status: True reason: Ready - type: ResourcesSubmitted status: Unknown reason: MissingValueAtPath message: Waiting to read value [.status.latestImage] from resource [images.kpack.io/cool-app] in namespace [default] - type: Ready status: Unknown reason: MissingValueAtPath
deliverable are taking a long time to become ready, then there might be an issue with the
resource or the output path
ResourcesSubmitted will help you locate the resource causing issues.
The most likely cause for this status is that the resource is unable to populate the specified path. Look at the resource’s status to diagnose the cause.
Resolving MissingValueAtPath when the resource is failing:
First look at the resource itself:
kubectl describe images.kpack.io/cool-app -n default
You will see that the value at path
.status.latestImage is not populated. Check the status and events of the resource,
consulting the documentation for the specific resource.
Resolving MissingValueAtPath when the path is incorrect:
Refer to the template specified resource’s documentation for the location of the required output.
For example, given the message
Waiting to read value [.status.latestImg] from resource [images.kpack.io/cool-app] in namespace [default]
- Look at the resources status, that’s the most likely place you’ll find the output you want
kubectl get images.kpack.io/cool-app -n default -oyaml` ... status: buildCounter: 5 conditions: - lastTransitionTime: "2021-11-09T03:16:54Z" status: "True" type: Ready - lastTransitionTime: "2021-11-09T03:16:54Z" status: "True" type: BuilderReady latestBuildImageGeneration: 2 latestBuildReason: STACK latestBuildRef: tanzu-java-web-app-build-5 latestImage: myrepo.io/tanzu-java-web-app@sha256:a92eafaf8a2e5ec306be44e29c9c5e0696bf2c6517b4627be1580c2d16f2ddb9 latestStack: io.buildpacks.stacks.bionic observedGeneration: 2
- Change the output path of the template to match, E.g: from
apiVersion: carto.run/v1alpha1 kind: ClusterImageTemplate metadata: name: kpack-template spec: imagePath: .status.latestImage
