Container Orchestration Jobs

The following topics describe job types for container orchestration platforms and services:

Job:AWS ECS

AWS Elastic Container Service (ECS) is a container management service that enables you to execute, stop, manage, and monitor containerized applications in a cluster.

To deploy and run an AWS ECS job, ensure that you have installed the AWS ECS plug-in with the provision image command or the provision agent::update command.

The following examples show how to define an AWS ECS job.

The following table describes the AWS ECS job parameters.

Parameter

Description

Connection Profile

Defines the ConnectionProfile:AWS ECS name that connects Control-M to AWS ECS.

Action

Determines one of the following actions to perform on AWS ECS:

  • Preset JSON: Runs the task according to the attributes that you define in this job.

  • Manual JSON: Runs the task according to the JSON parameters that you supply in the Parameters attribute to submit as a JSON body.

Parameters

Defines parameters to submit as a JSON body, to control how the AWS ECS task runs.

The JSON body replaces various other parameters described below, provided that you set the Action parameter to Manual Json.

For a description of this JSON syntax, see RunTask in the AWS ECS API Reference.

ECS Cluster Name

Defines the ECS cluster on the AWS ECS platform where the job runs.

An ECS cluster is a logical group of tasks and services.

ECS Task Definition

Defines the task definition on the AWS ECS platform.

The task definition describes the container image, command, environment variables, and other parameters that run your application.

Launch Type

Determines the type infrastructure where your tasks and services run:

  • Fargate: Runs your application on a virtual machine that is automatically provisioned and managed.

  • EC2: Runs your application on a predefined AWS EC2 virtual machine that you provision and manage.

  • External: Runs your application on a different virtual machine that you define in the AWS ECS platform.

Assign Public IP

Determines whether the job has a public internet protocol (IP).

Valid Values:

  • True

  • False

Network Security Groups

Defines which network security group your task is connected to, through the elastic network interface, which is a virtual network card that controls inbound and outbound traffic.

Network Subnets

Defines the virtual subnet, which determines the IP addresses for the task.

Override Container

Defines which override container to use that overrides the default container image, command, or other settings specified in the task definition.

Override Command

Defines the command to run in the container that overrides any command specified in the task definition.

Environment Variables

Defines the environment variables for the container, which are used to manage the container and pass information to the application that runs inside it.

Logs

Determines whether the logs from the AWS ECS platform appear at the end of the Control-M job output.

  • Get Logs

  • Don't Get Logs

Status Polling Frequency

Determines the number of seconds to wait before checking the status of the job.

Default: 10

Failure Tolerance

Determines the number of times to check the job status before ending Not OK.

Default: 5
