Unmanaged compute environments - Amazon Batch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Unmanaged compute environments

In an unmanaged compute environment, you manage your own compute resources. You must verify that the AMI you use for your compute resources meets the Amazon ECS container instance AMI specification. For more information, see Compute resource AMI specification and Tutorial: Create a compute resource AMI.

Note

Amazon Fargate resources aren't supported in unmanaged compute environments.

After you created your unmanaged compute environment, use the DescribeComputeEnvironments API operation to view the compute environment details. Find the Amazon ECS cluster that's associated with the environment and then manually launch your container instances into that Amazon ECS cluster.

The following Amazon CLI command also provides the Amazon ECS cluster ARN.

$ aws batch describe-compute-environments \
    --compute-environments unmanagedCE \
    --query "computeEnvironments[].ecsClusterArn"

For more information, see Launching an Amazon ECS container instance in the Amazon Elastic Container Service Developer Guide. When you launch your compute resources, specify the Amazon ECS cluster ARN that the resources register with the following Amazon EC2 user data. Replace ecsClusterArn with the cluster ARN that you obtained with the previous command.

#!/bin/bash
echo "ECS_CLUSTER=ecsClusterArn" >> /etc/ecs/ecs.config
