Debugging Installation Issues

General

invalid configuration: no configuration has been provided

This typically means that no kubeconfig file can be found for the Ark client to use. Ark looks for a kubeconfig in the following locations:

• the path specified by the --kubeconfig flag, if any
• the path specified by the $KUBECONFIG environment variable, if any
• ~/.kube/config

Backups or restores stuck in New phase

This means that the Ark controllers are not processing the backups/restores, which usually happens because the Ark server is not running. Check the pod description and logs for errors:

kubectl -n heptio-ark describe pods
kubectl -n heptio-ark logs deployment/ark

AWS

NoCredentialProviders: no valid providers in chain

This means that the secret containing the AWS IAM user credentials for Ark has not been created/mounted properly into the Ark server pod. Ensure the following:

• The cloud-credentials secret exists in the Ark server’s namespace

• The cloud-credentials secret has a single key, cloud, whose value is the contents of the credentials-ark file

• The credentials-ark file is formatted properly and has the correct values:

  [default]
  aws_access_key_id=<your AWS access key ID>
  aws_secret_access_key=<your AWS secret access key>
  

• The cloud-credentials secret is defined as a volume for the Ark deployment

• The cloud-credentials secret is being mounted into the Ark server pod at /credentials

Azure

Failed to refresh the Token or adal: Refresh request failed

This means that the secrets containing the Azure service principal credentials for Ark has not been created/mounted properly into the Ark server pod. Ensure the following:

• The cloud-credentials secret exists in the Ark server’s namespace
• The cloud-credentials secret has seven keys and each one has the correct value (see setup instructions)
• The cloud-credentials secret is defined as a volume for the Ark deployment
• The cloud-credentials secret is being mounted into the Ark server pod at /credentials

GCE/GKE

open credentials/cloud: no such file or directory

This means that the secret containing the GCE service account credentials for Ark has not been created/mounted properly into the Ark server pod. Ensure the following:

• The cloud-credentials secret exists in the Ark server’s namespace
• The cloud-credentials secret has a single key, cloud, whose value is the contents of the credentials-ark file
• The cloud-credentials secret is defined as a volume for the Ark deployment
• The cloud-credentials secret is being mounted into the Ark server pod at /credentials
