Getting started workflow 

Follow the workflow steps to get quickly started with provisioning and managing DataStax Enterprise cluster configurations in Lifecycle Manager.

Welcome to Lifecycle Manager! If you do not have any existing clusters in OpsCenter to manage in LCM, a getting started page appears:

The initial Lifecycle Manager workflow:

After creating SSH credentials (1), defining configuration profiles (2), adding a repository (3), and building the declarative cluster topology model (4), you are ready to run an install job to install and configure DataStax Enterprise (DSE) and monitor the install job (5).

Follow the linked workflow steps to quickly get started working with Lifecycle Manager:

Prerequisites

Bring your own instances on a supported platform.

Procedure

  1. Add SSH credentials so LCM can remotely log in to target machines when performing installation and configuration activities.
  2. Add a configuration profile that defines the required DSE configuration on the development, test, and production clusters for your organization. If the configuration of a cluster is intentionally heterogeneous and not uniform at all levels, you can create multiple configuration profiles to apply individually at the cluster, datacenter, or node levels.
  3. Add a repository so LCM can download the DSE software onto target machines from either the public DataStax repo or an internal install repo mirror set up by your organization.
  4. Define the topology of the cluster:
    1. Add a cluster.
    2. Add its datacenters.
    3. Add its nodes.
  5. Run an installation job of DataStax Enterprise at the cluster level. Lifecycle Manager installs and configures DataStax Enterprise on all datacenters and nodes within the cluster. With Lifecycle Manager, there is deep transparency into the progress of each installation and configuration job available when viewing job summary and details.

What's next

As a cluster grows and configuration options for various workloads require adjustments, running a configure job applies the configuration profiles across the cluster topology. To update the configuration of a cluster, edit its configuration profile and run a configuration job at the cluster level. LCM efficiently deploys the configuration changes across the cluster without duplicating work already completed in previous jobs.
