pension
Plan for your instances' retirement.
Pension checks for EC2 instance retirement (e.g. due to hardware failures) and other maintenance events that could cause (or be the source of) issues down the line. It is meant to be run periodically (in a cron or some such) and provide some warning before bad things happen.
Currently, pension knows how to ping a slack channel or send an email when something's broken. Additional notification methods are welcome contributions. Otherwise, parsing the JSON output format should be flexible enough for any internal notification tooling.
usage
pip install pension
pension [--dry-run] [--quiet] [--config path/to/pension.toml]
configuration
pension uses toml as its configuration
language. The config file can be specified on the command line via --config.
If not provided, pension will try ./pension.toml and ~/.pension.toml.
If no config file is available, pension will try to proceed using only AWS environment variables and the JSON console output.
For more information on AWS credentials, refer to the boto3 documentation.
