Deploying a Project to a Cluster

To run the projects you create in ESP Studio, add them to a cluster.

Prerequisites

Create a project.

Task

Set project options using the Project Configuration view in ESP Studio or by editing the project’s CCR file.
Read about project options in the sections that follow.
Add the project to the node:
```
esp_cluster_admin --uri=esp[s]://<host>:19011 --username=<username> --password=<password>
> add project <workspace-name>/<project-name> <project-name.ccx>
>
```
Note: If you omit the password parameter when you call the esp_cluster_admin tool, Event Stream Processor prompts you for the password and hides it as you type, which improves security.

Project Deployment Options
Project deployment options determine how your project is deployed in a cluster and how it functions at runtime. Set these parameters, including project options, active-active instances, failover intervals, and project deployment type options, in the CCR file manually or within Studio.
Active-Active Deployments
For high availability at the project level, configure active-active mode to create two instances of a project that run simultaneously.
Project Instances
High availability increases resiliency to failure by creating two project instances that run simultaneously.
Affinities
Set controller and instance affinities in the CCR file to determine which nodes a project can run on.
Failover
Enable or disable failover and set failover options.
Sample Project Configuration File
Use these project configuration CCR file examples to build and modify your XML-based project configuration file.
