DC/OS Custom Installation Options

DC/OS Custom Installation Options

You can install DC/OS on bare metal, virtual machines and every cloud. With the custom installers, you have the flexibility to configure each installation of DC/OS exactly how you like it.

GUI

You can use a simple graphical interface to configure and install DC/OS on your cluster. This method takes care of installing all the prerequisites on each instance along with everything required for DC/OS. Note that only a subset of the configuration options are available with this method. It is, however the fastest way to try out DC/OS on your own cluster.

CLI

For those who’d like a little bit more opportunity to configure things, the CLI installer is a great choice. It can take care of installing all the system requirements, just like the GUI installer. The advantage is that you’re able to pick more options as to exactly how your cluster is configured. An example of this would be the storage Exhibitor uses to bootstrap.

Advanced

When you’re ready to integrate DC/OS with your configuration management tools or create an image to roll out datacenter wide, the advanced installer is for you. This method provides you with all the flexibility you need to pick the actual installation process, every configuration option available and a simple way to consistently add agents to the cluster on a regular basis.


System Requirements

You must have a single bootstrap node, an odd number of Mesos master nodes, and any number Mesos of agent nodes.

GUI

The automated GUI installer provides a simple graphical interface that guides you through the installation of DC/OS. The automated installer provides a basic installation that is suitable for demonstrations and POCs. Only a subset of the configuration options are available with the GUI method. This is the fastest way to get started with DC/OS.

    CLI

    The automated CLI installer provides a guided installation of DC/OS from the command line. With this method you can choose from the complete set of DC/OS configuration options.

      Advanced

      With this installation method, you package the DC/OS distribution yourself and connect to every node manually to run the DC/OS installation commands. This installation method is recommended if you want to integrate with an existing system or if you don’t have SSH access to your cluster.

        Uninstall

        To remove DC/OS, you must completely reimage the operating system on your nodes. Uninstall will be supported in future releases. For more information, see DCOS-250 and DCOS-192.

          Configuration

          The DC/OS configuration parameters are specified in YAML format in a config.yaml file. This file is stored on your bootstrap node and is used during DC/OS installation to generate a customized DC/OS build.

          Configure Proxy

          By default the DC/OS Universe repository is hosted on the internet. If your DC/OS cluster is behind a corporate proxy, you must specify your proxy configuration in the configuration file file before installation. This will enable your cluster to connect to the Universe packages.

            Node and Cluster Health Checks

            Node and cluster health checks provide information about your cluster, including available ports, Mesos agent status, and IP detect script validation. A health check is a shell command that reports the status of a DC/OS cluster or node via its exit code. You can write your own custom health checks or use the predefined checks.
