This release note contains information about the Helm chart-related changes for the NetScaler Ingress Controller and GSLB controller version 1.41.5.

What's new

Automated Custom Resource Definitions (CRDs) installation using Helm

Earlier, CRDs installation was managed by specifying the crds.install parameter in the NSIC helm install command. If crds.install=true was specified, CRDs would be installed; if omitted, the CRD installation was skipped. If crds.install=true was specified in the NSIC helm install command and the cluster already had a CRD installed, the NSIC installation failed. Therefore, to specify the correct value for crds.install parameter, you had to know the status of the CRD installation in each cluster in your environment. Moreover, in an environment with multiple clusters, the process of updating the parameters became cumbersome and led to human error.

With this enhancement, Helm manages the CRD installations during the NSIC installation. When you run the NSIC helm install command, CRDs will be installed with NetScaler ingress controller via Helm automatically, if CRDs are not already installed in the cluster. If the CRDs already exist, the CRDs installation is skipped with a warning. Additionally, If you wish to skip the CRDs installation, you can specify the --skip-crds flag. For more information about this option in Helm, see here.

Fixed issues

  • The Helm chart's template function to populate the analytics server's IP address uses the 'first' and 'lookup' methods. However, if the lookup method returns "None", the first method fails with a "nil pointer dereference" error. The template function is enhanced to handle such a corner case.
