Function CI

FunctionCI is an open source Continuous Integration tool for AWS Lambdas.

Builds are done by AWS CodeBuild and AWS CodePipeline.

Receive build notifications via Slack. Deploy via Slack. View build and deployment audit trails via Slack.

Fork this repo and install FunctionCI in your AWS account, then start managing your Lambdas properly.


  • Serverless - Function CI only costs money when you use it
  • Github integration
  • Slack bot
  • Versioned build artifacts stored in S3
  • Build and deployment audit trails with Github commit version and Slack username

Use the /fn create project Slack command to create a new build project.

Once your build version is ready...

Deploy it using the /fn deploy fn <fn-name> <project-name> <version> Slack command.

Here is an example project:


  1. Fork and clone this repo.
  2. Install CIM (CloudFormation Utility)
  3. Install the kms stack.
  4. Install the app stack.

** If you fix or add anything please submit a Pull Request!!!


/fn create project

/fn create project

Register a new Github repo that you wish FunctionCI to build.

FunctionCI uses CodeBuild, so you will need a buildspec.yml in the root of your repo.

Here is an example buildspec.yml for a node.js project.

** Note you must export a single zip artifact.

version: 0.2

# aws/codebuild/eb-nodejs-6.10.0-amazonlinux-64:4.0.0
      - echo Installing source NPM dependencies...
      - npm install
      - echo Testing the code
      - npm test
      - echo Removing dev dependencies
      - rm -Rf node_modules
      - npm install --production
    - '**/*'

/fn show project

/fn show project <project_id>

Show the most recent builds in reverse chronological order.

The project_id will be <your repo name>-<branch>.


The project_id == functionci-demo-master

/fn show projects

/fn show projects

Show all the projects under management.

/fn delete project

/fn show project <project_id>

Delete the project and all build artifacts.

/fn add fn

/fn add fn <short_name> <lambda-name>

Add a Lambda function you wish to deploy build artifacts to.

Ex: /fn add fn demo functionci-demo-LambdaFunction-LFREQ3DEC3UJ

/fn show fn

/fn show fn <short_name>

Show a function and all its deployment history.

Ex: /fn show fn demo

/fn show fns

/fn show fns

Show all the functions under management

Ex: /fn show fns

/fn deploy fn

/fn deploy fn <short_name> <project_id> <version>

Deploy a build artifact to the Lambda function.

Ex: /fn deploy fn demo functionci-demo-master 1

/fn delete fn

/fn delete fn <short_name>

Delete a function and all its deployment history.

Ex: /fn delete fn demo


FunctionCI is also a serverless Lambda app. It includes the following AWS resources:

  • API Gateway (Exposes an API for our Slack bot)
  • Lambda (Slack bot API, SNS events, CloudWatch events, CodePipeline events)
  • DynamoDB (Document storage)
  • S3 (Build artifacts)
  • CloudFormation (Builds a pipeline for each project)
  • CodePipeline and CodeBuild (Performs builds)

Create Project

When you create a new project FunctionCI creates a new CloudFormation stack. This stack is the build pipeline for your project.

Build Project

When you commit changes to your Github repo CodePipeline is triggered. The first CodePipeline stage is CodeBuild to build, test, and package your app. The next CodePipeline stage is the FunctionCI Lambda to version and archive the build artifact.

Deploy Lambda

Now we are ready to deploy our build artifact to our Lambda.

You can’t perform that action at this time.
