How to stop all running Step Functions of a specific state machine?

问题

I accidentally started very many step functions and now wish to terminate all of them.

Any smart ways to do this using the CLI or web console?

OK, let's do this using the CLI.

You can stop an execution using the following:

aws stepfunctions stop-execution \
  --execution-arn <STEP FUNCTION EXECUTION ARN>

But since I started way too many executions, it's helpful to be able to list all running executions of a state machine:

aws stepfunctions list-executions \
  --state-machine-arn <STEP FUNCTION ARN> \
  --status-filter RUNNING \
  --output text

Next, make sure to only list execution ARN's for these executions and list each execution ARN on a separate line:

aws stepfunctions list-executions \
  --state-machine-arn <STEP FUNCTION ARN> \
  --status-filter RUNNING \
  --query "executions[*].{executionArn:executionArn}" \
  --output text

Now, we put this together into one command using xargs:

aws stepfunctions list-executions \
  --state-machine-arn <STEP FUNCTION ARN> \
  --status-filter RUNNING \
  --query "executions[*].{executionArn:executionArn}" \
  --output text | \
xargs -I {} aws stepfunctions stop-execution \
  --execution-arn {}

Now all running executions should be shut down. Make sure you do this with care so that you don't mess up production!

On that note, if you user aws-vault to minimize that very risk, the command above would look something like this:

aws-vault exec test-env -- aws stepfunctions list-executions \
  --state-machine-arn <STEP FUNCTION ARN> \
  --status-filter RUNNING \
  --query "executions[*].{executionArn:executionArn}" \
  --output text | \
xargs -I {} aws-vault exec test-env -- aws stepfunctions stop-execution \
  --execution-arn {}
