Deckhouse Platform for bare metal

Installation process

You will need:

  1. Personal computer.

    The computer from which the installation will be performed. It is only needed to run the Deckhouse installer and will not be part of the cluster.

    Requirements:

    • OS: Windows 10+, macOS 10.15+, Linux (e.g. Ubuntu 18.04+, Fedora 35+);
    • installed docker to run the installer (here are the instructions for Ubuntu, macOS, Windows);

    • HTTPS access to the registry.deckhouse.io container image registry (it is also possible to use a third-party registry);
    • SSH key access to the node, the master node of the future cluster.
  2. Master-node (nodes).

    A server (physical server or virtual machine), the master node of the future cluster.

    During the installation, the Deckhouse installer running on the personal computer (section 1) will connect to that host via SSH, install necessary packages, configure control plane Kubernetes, and deploy Deckhouse.

    Note that master node-based installation is not currently supported.

    Requirements:

    • at least 4 CPU cores;
    • at least 8 GB of RAM;
    • at least 40 GB of disk space for the cluster and etcd data;
    • supported OS;

    • HTTPS access to the registry.deckhouse.io container image registry (it is also possible to use a third-party registry);
    • SSH key access from the personal computer (section 1);
    • container runtime packages, such as containerd or docker, should not be installed on the node.
  3. Additional nodes (not required).

    Depending on the purpose of the cluster, you may need additional nodes, for example, worker nodes, dedicated nodes for monitoring, dedicated nodes for load balancers (frontend nodes), etc.

    Below are the minimum requirements for any node (node group):

    • supported OS;

    • HTTPS access to the registry.deckhouse.io container image registry (it is also possible to use a third-party registry).
    • container runtime packages, such as containerd or docker, should not be installed on the node.

    Below are the minimum requirements for any node (node group) with the monitoring role (learn more):

    • at least 4 CPU cores;
    • at least 8 GB of RAM.

    By default, the default storage class defined in the cluster is used as storage for system components (or emptydir, if it is not defined). You can specify the storage class using the global parameter storageClass.

The presentation below is an overview of the actions that will be required to install Deckhouse Platform. While it’s totally fine to skip it, we recommend that you watch it to better understand the following steps.

Note that it’s only a brief, abstract overview. The specific actions and commands to execute will be given on the next steps.
