Support and Troubleshooting
Supported Kubernetes Versions
K10 currently supports the following certified Kubernetes distributions and OpenShift versions:
Kubernetes (including managed services)
Snapshots created using the v1alpha1 Snapshot CRDs are incompatible with the v1beta1 Snapshot CRD. Please contact your CSI storage provider for an upgrade path. However, any backups taken using the v1alpha1 CRD functionality will still be available for restore.
K10 4.0.5 or earlier may still run on older, unsupported versions of Kubernetes and OpenShift. Please install K10 4.0.5 on OpenShift 4.2 or earlier and Kubernetes 1.15 or earlier.
Gathering Debugging Information
Admin users running 4.5.7 or later can get support logs in the dashboard under Settings -> Support.
Alternatively, if you run into problems with K10, please run these commands
on your cluster as a first step to get information to support. The script
assumes that your default
kubectl context is pointed to the
cluster you have installed K10 on and that K10 is installed in
$ curl -s https://docs.kasten.io/tools/k10_debug.sh | \ bash;
By default, the debug script will generate a compressed archive file
k10_debug_logs.tar.gz which will have separate log files
for K10 services.
To gather K10's Prometheus statistics the script will create a port forward
using the port
9090 in the host where the script is executed.
If you installed K10 in a different namespace, want to log to a different file or want to use a different local host port to gather statistics, the options to the debug script are:
$ curl -s https://docs.kasten.io/tools/k10_debug.sh | \ bash -s <k10-namespace> <logfile-name> <localhost port>;
Application Debug Information
If you are having issues with a particular application, please also gather the following information.
# Get Application Information $ kubectl get pvc -oyaml --namespace <APP NAMESPACE> $ kubectl api-resources --verbs=list --namespaced -o name | \ xargs -n 1 kubectl get --show-kind --ignore-not-found --namespace <APP NAMESPACE>
Please also get the Helm status:
# If deployed via Helm $ helm status <RELEASE NAME> --namespace=<APP NAMESPACE>
k10tools binary has commands that can help with validating
if a cluster is setup correctly before installing K10 and for
debugging K10's micro services.

k10tools can be found
