In case above services are needed and software are not installed in CNE. Install all the required software before proceeding for SCP Installation.

Network access

The Kubernetes cluster hosts must have network access to:

• Local docker image repository where the SCP images are available
• Local helm repository where the SCP helm charts are available
• Service FQDN of SCP-Worker must be discoverable from outside of the cluster (i.e. publicly exposed so that ingress messages to SCP can come from outside of Kubernetes).
• Helm must have access to create ClusterRole and ClusterRoleBinding resources.

Note:

All the kubectl and helm related commands used in this guide need to be executed on some machine depending on the infrastructure/deployment. It may be some client machine.

Client machine requirements

There are some requirements for the laptop/desktop where the deployment commands needs to be executed:

• It should have network access to the helm repository and docker image repository.
• Helm repository must be configured on the client.
• It should have network access to the Kubernetes cluster.
• It should have necessary environment settings to run the kubectl commands. The environment should have privileges to create namespace in the Kubernetes cluster.
• It should have helm client installed with the push plugin. The environment should be configured so that the helm install command deploys the software in the Kubernetes cluster.
