Using MustGather scripts to collect environment data

You can use the mustgather command to collect data about your environment. This information can be useful in troubleshooting and fixing problems.

There are several MustGather scripts available in the kabanero-foundation/scripts/mustgather directory:









Run a MustGather Script

  1. In a terminal session, navigate to the location where you cloned the kabanero-foundation repository and go to the kabanero-foundation/scripts/mustgather directory.

  2. Log in to your cluster.

    oc login https://<your_cluster_hostname> -u <username> -p <password>
  3. Run a mustgather script.

    For example:


Tip: You can set the environment variable LOGS_DIR to specify the data output location:

LOGS_DIR=<my_directory> ./

By default, MustGather data is stored in the kabanero-debug directory. The command also stores compressed information in the kabanero-debug-<timestamp>.tar.gz file.

Errors when using a Tekton webhook to trigger pipelines

When using a Tekton webhook to trigger pipelines installed with Kabanero, the last task is the monitor-result-task, which may fail in some cases. This might also cause the webhook pod to be in the "Error" state. The following failures of monitor-result-task in the TaskRun view can be disregarded at this time; they do not impact the application deployment:

  • error creating GitHub client: error parsing PR number: pulls

  • IOError: [Errno 2] No such file or directory: '/workspace/pull-request/pr.json'

docker push fails with gateway timeout error

When using OpenShift Container Platform on a cloud with Kubernetes service and an internal Docker registry, performing a docker push into the internal Docker registry might result in a gateway time-out error. This happens in cases where the input-output operations per second (IOPS) setting for the backing storage of the registry’s persistent volume (PV) is too low.

To resolve this problem, change the IOPS setting of the PV’s backing storage device.
