The presentation contains an overview of the actions required to install Deckhouse.

Installation requirements

  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;
    • SSH key access to the node, the master node of the future cluster.

  2. Physical server or virtual machine for the master node.

    Requirements...

    • at least 4 CPU cores
    • at least 8 GB of RAM
    • at least 60 GB of disk space for the cluster and etcd data on a fast disk (400+ IOPS)
    • supported OS
    • Linux kernel version >= 5.7
    • Unique hostname within servers (virtual machines) of the cluster
    • one of the package managers (apt/apt-get, yum, or rpm) should be installed

    • Python should be installed

    • HTTPS access to the registry.deckhouse.io container image registry
    • access to the default package repositories for the operating system you are using;
    • SSH key access from the personal computer (section 1)
    • network access from the personal computer (section 1) via port 22322/TCP
    • container runtime packages, such as containerd or docker, should not be installed on the node

  3. Physical server or virtual machine for the worker node.

    The requirements are similar to the requirements for the master node but also depend on the applications running on the nodes.

The recommendations above provide the minimum resources required for the initial deployment of a cluster with one master node and one worker node. This configuration is sufficient for introductory purposes, but it is not suitable for production environments. Read the recommendations for preparing for production and the instructions for choosing the types and number of cluster nodes, as well as the resources for them, depending on your requirements for the operation of the future cluster.
