Deploying KEDA on TKE

Add helm repo​

helm repo add kedacore https://kedacore.github.io/charts
helm repo update

Prepare values.yaml​

First check the default values.yaml (to see what configuration options can be customized)

helm show values kedacore/keda

The default dependency images cannot be pulled in domestic environments. You can replace them with mirror images from Docker Hub by configuring values.yaml:

image:
  keda:
    registry: docker.io
    repository: imroc/keda
  metricsApiServer:
    registry: docker.io
    repository: imroc/keda-metrics-apiserver
  webhooks:
    registry: docker.io
    repository: imroc/keda-admission-webhooks
Note

The above mirror images are automatically synced long-term and can be used and updated with confidence.

Install​

helm upgrade --install keda kedacore/keda \
  --namespace keda --create-namespace \
  -f values.yaml

Versioning and Upgrades​

Each KEDA version has a corresponding supported K8S version range. If your TKE cluster version is not particularly new, installing the latest KEDA version may not be compatible. You can check KEDA Kubernetes Compatibility to confirm which KEDA version is compatible with your current cluster version.

For example, if the TKE cluster version is 1.26, the latest compatible KEDA version is v2.12. Then query to find that KEDA v2.12 (APP VERSION) corresponds to the highest Chart version (CHART VERSION) of 2.12.1:

$ helm search repo keda --versions
NAME                                            CHART VERSION   APP VERSION     DESCRIPTION
kedacore/keda                                   2.13.2          2.13.1          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.13.1          2.13.0          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.13.0          2.13.0          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.12.1          2.12.1          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.12.0          2.12.0          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.11.2          2.11.2          Event-based autoscaler for workloads on Kubernetes
kedacore/keda                                   2.11.1          2.11.1          Event-based autoscaler for workloads on Kubernetes

Specify the version when installing KEDA:

helm upgrade --install keda kedacore/keda \
  --namespace keda --create-namespace \
  --version 2.12.1 \
  -f values.yaml

For subsequent version upgrades, you can reuse the above installation command, only modifying the version number.

Note: Before upgrading the TKE cluster, also use this method to first confirm whether the upgraded cluster version can be compatible with the current KEDA version. If not, please upgrade KEDA in advance to the latest KEDA version compatible with the current cluster version.

Uninstall​

Refer to official uninstall documentation.
