Chalice CI/CD App

Table of Contents

Overview

chalice-cicd-app is a template repo for a serverless application using the AWS Chalice serverless framework. This repo includes both a hello-world Chalice app, as well as a CI/CD pipeline for deploying the code written using the AWS Cloud Development Kit. It is highly recommended that developers have a working understanding of the CDK, Chalice framework, and the underlying serverless AWS resources being manipulated during serverless development.

Installation

AWS CDK

To install the AWS CDK, please follow the AWS CDK installation instructions.

Setting up your environment

To set up your environment, follow these steps:

git clone https://github.com/folksgl/chalice-cicd-app.git
cd chalice-cicd-app
python3 -m venv venv38
source venv38/bin/activate
python3 -m pip install -r requirements.txt
pre-commit install

Development Flow

The development flow for this repo can be split into two streams. Work on the CI/CD pipeline to deploy the application is found under the pipeline while the application code can be done in the app directory.

Deploying the Chalice application

All deployments require having the correct AWS CLI credentials in place. If you haven't already, install the AWS CLI and set up credentials to your account.

With the CI/CD pipeline

Before deploying with the CI/CD pipeline, you must create a CodeStar Connection to the GitHub account your repo is located in. Once that connection is created, store the ARN of the connection in a SecretsManager Secret, with the JSON key of 'arn'. In JSON, the secret should look like the following:

{ "arn": "<my-connection-arn>" }

To deploy the application with the CI/CD pipeline:

cd pipeline
cdk deploy --parameters ConnectionSecretId=<secret-id>

Without the pipeline

Deployments without the pipeline must change directories into the hello world directory. Chalice deployments can make direct usage of the chalice CLI tool using chalice local or chalice deploy commands. Please use chalice --help and see the Chalice documentation.
