= Additional requirements for installing {sno} on a cloud provider
|
|
|
|
The documentation for installer-provisioned installation on cloud providers is based on a high availability cluster consisting of three control plane nodes. When referring to the documentation, consider the differences between the requirements for a {sno} cluster and a high availability cluster.
|
|
|
|
* A high availability cluster requires a temporary bootstrap machine, three control plane machines, and at least two compute machines. For a {sno} cluster, you need only a temporary bootstrap machine and one cloud instance for the control plane node and no compute nodes.
|
|
|
|
* The minimum resource requirements for high availability cluster installation include a control plane node with 4 vCPUs and 100GB of storage. For a {sno} cluster, you must have a minimum of 8 vCPUs and 120GB of storage.

The documentation for installer-provisioned installation on cloud providers is based on a high availability cluster consisting of three control plane nodes. When referring to the documentation, consider the differences between the requirements for a {sno-okd} cluster and a high availability cluster.
|
|
|
|
* A high availability cluster requires a temporary bootstrap machine, three control plane machines, and at least two compute machines. For a {sno-okd} cluster, you need only a temporary bootstrap machine and one cloud instance for the control plane node and no worker nodes.
|
|
|
|
* The minimum resource requirements for high availability cluster installation include a control plane node with 4 vCPUs and 100GB of storage. For a {sno-okd} cluster, you must have a minimum of 8 vCPU cores and 120GB of storage.

|
|
* The `controlPlane.replicas` setting in the `install-config.yaml` file should be set to `1`.
|
|
|
|
* The `compute.replicas` setting in the `install-config.yaml` file should be set to `0`.
|
|
This makes the control plane node schedulable.
