As mentioned in the comments, there are a couple issues with your manifests. They're valid YAML, but that YAML does not deserialize into valid Argo custom resources.

In the Workflow, you have duplicated the parameters key in spec.templates[0].inputs.
In the WorkflowTemplate, you have placed the configMapRef and secretRef names at the same level as the keys. configMapRef and secretRef are objects, so the name key should be nested under each of those.

These are the corrected manifests:

QUESTION

How do I view the logs from a task in Argo?

Asked 2021-Apr-20 at 14:10

I am using Argo and have a question about the workflow of workflows example. (https://github.com/argoproj/argo-workflows/blob/master/examples/workflow-of-workflows.yaml)

UPDATED YET AGAIN

As pointed out below, it is a task that I need to view. So my question is now - How do I view the logs from a task?

My workflow completes without error, but does not produce the expected output. I would like to look at the logs of one of the containers within one of the workflows within the overall workflow, but I cannot get the syntax right I am using the following convention to get the logs from the relevant pod.

...

ANSWER

Answered 2021-Apr-05 at 21:25

The default container names on an Argo Workflows pod are init, main, and wait.

I'm not sure what message-passing-1-t8749 refers to, but it might be the "step/task name."

QUESTION

How to parameterize a workflowTempateRef?

Asked 2021-Mar-29 at 18:32

I have a WorkflowTemplate "nyc-test-template" which I trigger via Argo Events and PubSub. So, if I publish a message {} into the PubSub topic "argo-events-nyc" the template specified via a workflowTempateRef is started. That does work just fine. Now I want to parameterize the to be started template.

My not-working draft looks as follows:

Answered 2021-Mar-29 at 18:12

You can use when to toggle which template to use depending on a parameter.

Suppose I have two simple WorkflowTemplates like these:

QUESTION

How to prevent Argo Workflow from being resubmitted if it is already running?

Asked 2021-Feb-23 at 18:21

The use case is that we think about triggering an Argo Workflow via Argo Events with PubSub. PubSub does not guarantee that a message is delivered only once. Is there an easy method to prevent a Workflow from being triggered again when it is running already?

Something like the concurrencyPolicy setting for CronWorkflows.

To have something to look at - let's assume the whalesay Workflow:

ANSWER

Answered 2021-Feb-23 at 18:20

If you just need to make sure the Workflow doesn't run more than one simultaneous instance, use Argo's built-in synchronization feature.

Accessing argo workflow archive via http leads to permission denied error

Asked 2021-Feb-15 at 21:59

I'm trying to access the Argo workflow archive via the REST API. The documentation states that I need to create a role and a token, so I that's what I did. A role with minimal permissions can be created like so:

ANSWER

Answered 2021-Feb-15 at 21:59

Looks like the role/serviceaccount/rolebinding created according to the docs only grant permissions to list Workflows in the argo namespace (whether archived or not).

The namespace can be specified for the Archive like so:

Argo allows you to scale vertically by adding multiple workflow controllers. Each controller gets an "instance ID."

Your CronWorkflow specifies the fp workflow controller instance.

Argo sample workflows stuck in the pending state

I follow the Argo Workflow's Getting Started documentation. Everything goes smooth until I run the first sample workflow as described in 4. Run Sample Workflows. The workflow just gets stuck in the pending state:

ANSWER

Answered 2020-May-14 at 16:15

Workflows start in the Pending state and then are moved through their steps by the workflow-controller pod (which is installed in the cluster as part of Argo).

The workflow-controller pod is stuck in ContainerCreating. kc describe po {workflow-controller pod} reveals a Calico-related network error.

As mentioned in the comments, it looks like a common Calico error. Once you clear that up, your hello-world workflow should execute just fine.

Note from OP: Further debugging confirms the Calico problem (Calico nodes are not in the running state):
