Upgrade DxE + SQL Server Helm Deployments

Prerequisites​

  • Current environment was deployed using the DH2i Helm chart.

  • Kubernetes statefulset updateStrategy spec is set to OnDelete.

Using Helm to Upgrade the Container Images​

  1. Stage the upgrade with new image tags.
Upgrading SQL Server 2019 to SQL Server 2022
helm upgrade <helm_installation_name> dh2i/dxemssql --reuse-values --set=sqlImage.tag="2022-latest"
Upgrading DxEnterprise to a Newer Version
helm upgrade <helm_installation_name> dh2i/dxemssql
tip

Any image that uses the latest tag will automatically be upgraded with the above commands whenever a new image is posted to the repository. If a specific image version is required, then use the --set parameter to specify the desired tag. The DH2i Helm chart uses "sqlImage.tag" for SQL Server and "dxeImage.tag" for DxEnterprise.

For example:

helm upgrade dh2i_test dh2i/dxemssql --reuse-values --set=sqlImage.tag="2019-CU14-rhel-8.4" --set=dxeImage.tag="23.0.256.0-rhel8-arm64"

  1. Delete each pod individually to perform the upgrade.
info

It's highly recommended to upgrade the secondary pods one at a time before upgrading the primary pod. After upgrading all of the secondary pods, then move the Vhost to one of them and upgrade the final pod.
