pcluster delete - AWS ParallelCluster

pcluster delete

Deletes a cluster.

pcluster delete [ -h ] [ -c CONFIG_FILE ] [ -r REGION ] [ -nw ] cluster_name

Positional arguments


Specifies the name of the cluster to delete.

Named arguments

-h, --help

Shows the help text for pcluster delete.


Specifies the alternative configuration file to use.

Defaults to ~/.parallelcluster/config.


Keep the CloudWatch Logs data after deleting the cluster. The log group remains until you delete it manually, but the log events expire based on the retention_days setting. The setting defaults to 14 days.


Support for the --keep-logs argument was added in AWS ParallelCluster version 2.6.0.

-r REGION, --region REGION

Specifies the AWS Region to use. Defaults to the Region specified by using the pcluster configure command.

When the command is called and begins polling for the status of that call, it is safe to use "Ctrl-C" to exit. You can return to viewing the current status by calling pcluster status mycluster.

If pcluster configure created a new VPC, you can delete that VPC by deleting the AWS CloudFormation stack it created. The name will start with "parallelclusternetworking-" and contain the creation time in a "YYYYMMDDHHMMSS" format. You can list the stacks using the list-stacks command.

$ aws --region us-east-2 cloudformation list-stacks \ --stack-status-filter "CREATE_COMPLETE" \ --query "StackSummaries[].StackName" | \ grep -e "parallelclusternetworking-" "parallelclusternetworking-pubpriv-20191029205804"

The stack can be deleted using the delete-stack command.

$ aws --region us-west-2 cloudformation delete-stack \ --stack-name parallelclusternetworking-pubpriv-20191029205804
