# lambda-distro-support
This repository contains lambda functions for distro support tasks.
## Setup
* Install [docker](https://docs.docker.com/get-docker/)
* Clone this repository
* Navigate to the lambda you want to work on in `lambda/`

## Running

### Start Container
```
$ docker-compose up --build -d function
```

### Execute Function
Use the HTTP client of your choice. The body of the request is the `event` passed into the function.

```
curl --request POST \
  --url http://localhost:9000/2015-03-31/functions/function/invocations \
  --header 'Content-Type: application/json' \
  --data '{
	"num": 2
}'
```

### Load Changes
The `src` directory and `config.py` are mounted into the container via the `docker-compose.yaml` configuration. This means you don't need to re-build the entire container to see changes. **However** the container will need to be restarted. This process should be as quick as restarting uwsgi when making changes to a web application.
```
$ docker-compose restart function
```
:zap: You should add this command to a post-write hook in your preferred editor to automatically restart.

## Linting and Testing

### Run Container
```
$ docker-compose up --build lint-and-test
```

### Set pytest Options
Sometimes you may want to customize how tests run using [pytest options](https://docs.pytest.org/en/stable/usage.html) when doing development locally, only running a subset of tests using `-k` for example. Simply edit `TEST_ARGS` value in `docker-compose.yaml`, **without** quotes, to set the options you need.

:warning: Careful not to commit changes

### Skip Linting
When developing locally, you might not want to worry about linting when working to make tests pass. Simple edit the `SKIP_LINT` value in `docker-compose.yaml` to be `1`.

:warning: Careful not to commit changes

### Capture Exit Code
Unless the container itself crashes, or is killed, the exit code will be `0`. When the exit code of `lint-and-test.sh` script matters, a pull-request builder for example, run tests with the following flags.
```
$ docker-compose up --exit-code-from lint-and-test --abort-on-container-exit --build lint-and-test
