Gicha CLI

The Python CLI for maintaining a Gicha stack... or dozens of them!

Use cases

Install gicha and list all possible parameters

pip install gicha
python -m gicha --help

Create a completely new project

python -m gicha --app-name=gicha-base

Those configurations will be automatically saved in gicha.yml at the end of the creation.

Upgrade an already existing project

pip install gicha --upgrade
python -m gicha --app-name=gicha-base --output-dir=folder-already-created

Note the --upgrade and the --output-dir=folder-already-created flags. The Gicha configuration that was used for the previous generation is saved in gicha.yml: it will be updated after the new upgrade.

If you want to do an upgrade without re-specifying each parameter (there are a lot of them!), then gicha conveniently provides de --gicha-conf parameter. Just modify the existing gicha.yml (modify mandatorily the version parameter so that it reflects the newly upgraded version, modify optionally any other parameter depending on your needs), then:

pip install gicha --upgrade
cd folder-already-created
python -m gicha --gicha-conf=gicha.yml --output-dir=.

Activate Function URL

If your calls last longer than 30 seconds (but less than 15 minutes), then you need to do the invocations through Function URL.

1. Call Gicha --with-function-url=true. This will just save the configuration in gicha.yml for now. You need to additionally perform the following two instructions.
2. Activate Function URL. You can use either AWS Console or CLI.
3. Set handler to app.minimalistic_handler. You can use either AWS Console or CLI.

- TODO: automate step 2 and 3

- When calls are done through Function URL,
- then Chalice routing with @app.route does __NOT__ work:
- route manually!
