Stack

Core of this tool create a EC2 instance via cloudformation.

❯ AWS_PROFILE=dev tchotcho stack --help
Usage: tchotcho stack [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  create
  delete
  list

Create

Create a cloudformation stack. The name needs to be the same as the imported key in aws.

Usage:

❯ AWS_PROFILE=dev tchotcho stack create --help
Usage: tchotcho stack create [OPTIONS]

Options:
  --name TEXT            Name of stack to create && key  [required]
  --ami TEXT             Name of ami to use  [default: ami-061aaaac62de85935;
                         required]

  --inst TEXT            Name of the instance to use  [required]
  --security_group TEXT  Name of the security group to use
  --subnet TEXT          Name of the subnet to use

  --help                 Show this message and exit.

Example:

❯ AWS_PROFILE=dev tchotcho stack create --name test-dl --inst t2.medium --price 0.02 --dry

User script

TODO Currently only via the api changeable. Explain:

• waiting for apt via flock
• signal to cloudformation so we wait until user script install is finished

Code style

We use flake8 to ensure code quality and black to autoformat code.

Add it as a git-hook:

$ flake8 --install-hook git
$ git config --bool flake8.strict true

TODO

• Try paramiko + scp to be pure python
