cfn-tail is a NodeJS command line tool to follow the events of a AWS CloudFormation stack.
The region to use is determined by the environment variable AWS_DEFAULT_REGION.
To install cfn-tail open a terminal and issue: npm install -g cfn-tail
To follow stack events type cfn-tail <stackname> in a shell.
You have to provide the desired AWS region using the AWS_DEFAULT_REGION environment variable or using the --region option.
cfn-tail --region eu-west-1 <stackname>
Logging will stop if the stack creation or update completes or fails.
--retryMs <number>specifies the value in milliseconds to use for custom exponential backoff; defaults to700. Use this option if you frequently experience API throttling errors.--color <bool>specifies whether to colorize the output; defaults totrue
