Using your existing Kubernetes (K8S) cluster

This guide explains how to use the provisioning script to generate all the K8S components needed to run MetaDefender ICAP Server in your-already-created K8S cluster.

That requires some configuration options to be chosen, and the helm chart values to be configured properly.

Customized Installation

As for the demand of customizing the installation of our MetaDefender ICAP Server product in a K8S cluster, we have published the helm chart on GitHub: https://github.com/OPSWAT/metadefender-k8s/tree/main/helm_charts/icap

How to Install MetaDefender ICAP Server using Helm

This chart can deploy the following depending on your chosen configuration options:

One or more MD ICAP Server instances

git clone https://github.com/OPSWAT/metadefender-k8s.git cd metadefender/helm_carts/icap helm install md-icapsrv ./icap . #You can replace the file for specific scenario

Remarkable Configuration Options

Trouble shooting

How to check the logs with Kubectl

In case the md-icapsrv pod does not initialize we need to check the init container logs to see why is failing
1. The worker node running the md-icapsrv pod doesn’t have enough resources allocated for the pod.
2. Provide the License Key in file values.yml for activation-manager container can run.
3. Need to set value ACCEPT_EULA is true if the application can not start with reason accept EULA.
4. If you have enabled TLS to need to uncomment scheme: HTTPS in health check. The key of the secret need to mapping with the field .certSecretSubPath and .certKeySecretSubPath

Kubernetes Management Platform Recommended

To administrate the Kubernetes cluster and see all the components installed from the same point we recommend using Lens Desktop
