使用 Universal 安装工具在 AWS 上配置您的 DC/OS 安装

The Mesosphere Universal Installer supports a wide range of inputs/variables to add to your main.tf and enable you to customize your DC/OS cluster to your needs. These inputs/variables include everything from specifying the operating system (CentOS, Ubuntu, RHEL, Oracle Linux) to setting the garbage collection time of your DC/OS cluster.

The Terraform-based Universal Installer is designed to be flexible with configuration. Below is an example of a custom main.tf that provisions a customized DC/OS 1.13.3 cluster on AWS.

  # Change your default region here
  region = "us-east-1"
}

Supported DC/OS Versions

Currently, the Universal Installer defaults to 1.11.4 when using v0.1.0 modules and 1.13.3 for v0.2.0 modules. The following versions of DC/OS are currently supported. It is always recommended to specify a version.

dcos_version: "1.13.3"

Supported Instance (Node) OS Versions

The default instance OS is currently centos_7.5, and will be applied unless specified in the configuration. The following instance operating systems are supported by DC/OS. To change the default OS, the following paramaters can be changed:

dcos_instance_os = "centos_7.5"

Here is a list of all the variables that are currently supported on the Universal Installer and available for you to customize your cluster.
