The Default Katib Standalone Installation
Follow the installation guide to install the default version of Katib control plane.
Katib with Controller Leader Election
Run the following command to deploy Katib with Controller Leader Election support:
kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-leader-election?ref=master"
This installation is almost the same as Katib Standalone installation, although you can make
katib-controller
Highly Available (HA) using leader election. If you plan to use Katib in an
environment where high Service Level Agreements (SLAs) and Service Level Objectives (SLOs)
are required, such as a production environment, consider choosing this installation.

kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-standalone-postgres?ref=master"
Katib with External DB
Run the following command to deploy Katib with custom DB backend:
kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-external-db?ref=master"
This installation allows to use custom instance of MySQL DB instead katib-mysql
.
You have to modify the appropriate environment variables for katib-db-manager
in the
secrets.env
with your MySQL DB values.
Katib with Cert Manager
Run the following command to deploy Katib with Cert Manager requirement:
kubectl apply -k "github.com/kubeflow/katib.git/manifests/v1beta1/installs/katib-cert-manager?ref=master"
