Argo: workflow-controller-configmap misses the `config` key

[makeItFuckingSustainable]

What happened:

I applied a minimal version of the workflow-controller-configmap from https://raw.githubusercontent.com/argoproj/argo/master/docs/workflow-controller-configmap.yaml:

The workflow-controller logs gave:

time="2020-03-24T14:20:54Z" level=warning msg="ConfigMap 'workflow-controller-configmap' does not have key 'config'"
time="2020-03-24T14:20:54Z" level=info msg="workflow controller configuration from workflow-controller-configmap:\n"

No default artifact registry was configured.

What you expected to happen:

I expected to see log entries in the workflow-controller of the form

time="2020-03-24T14:42:08Z" level=info msg="Detected ConfigMap update. Updating the controller config."
time="2020-03-24T14:42:08Z" level=info msg="workflow controller configuration from workflow-controller-configmap:\nartifactRepository: \n  archiveLogs: true\n  s3:\n    endpoint: s3.amazonaws.com\n    bucket: my-bucket\n    region: us-west-2\n    insecure: false\n    accessKeySecret:\n      name: my-s3-credentials\n      key: accessKey\n    secretKeySecret:\n      name: my-s3-credentials\n      key: secretKey\n"

How to reproduce it (as minimally and precisely as possible):

Prerequisites:

• Assuming that argo workflows is installed into the argo namespace.
• Argo workflow controller uses image argoproj/workflow-controller:v2.6.3

cat > test_config.yaml <<<EOF
apiVersion: v1
kind: ConfigMap
metadata:
  name: workflow-controller-configmap
  namespace: argo
data:
  artifactRepository: |
    archiveLogs: true
    s3:
      endpoint: s3.amazonaws.com
      bucket: my-bucket
      region: us-west-2
      insecure: false
      accessKeySecret:
        name: my-s3-credentials
        key: accessKey
      secretKeySecret:
        name: my-s3-credentials
        key: secretKey
EOF

kubectl apply -f test_config.yaml
kubectl logs -n argo $(kubectl get pods -l app=workflow-controller -n argo -o name)

Anything else we need to know?:

proposed solution:

Add a missing sub-key config into the workflow-controller-configmap as

apiVersion: v1
kind: ConfigMap
metadata:
  name: workflow-controller-configmap
  namespace: argo
data:
  config: |
    artifactRepository: 
...

Note, that the remaining pipe symbols "|" have to be taken out (e.g. after artifactRepository).

Environment:

• Argo version: v2.6.3 (in cluster)
• Argo version: v2.6.2 (cli)
• Kubernetes version : v1.11.10

Other debugging information (if applicable):

• workflow-controller logs:

kubectl logs -n argo $(kubectl get pods -l app=workflow-controller -n argo -o name)

time="2020-03-24T14:20:54Z" level=warning msg="ConfigMap 'workflow-controller-configmap' does not have key 'config'"
time="2020-03-24T14:20:54Z" level=info msg="workflow controller configuration from workflow-controller-configmap:\n"

Hi @makeItFuckingSustainable, we are upgrading the way we structure our configuration maps and the changes you linked have not been in a release yet.

Could you take a look at this version of the file? It should work for you

[simster7]

@alexec We need to make sure we have both versions of the config map in our docs, so that users who are not yet on 2.7 don't run into issues.

Hi @simster7, my proposed solution seems to match that. Thanks for getting back to me so quickly.

Thanks for bringing this up
