The definition of the application to be deployed can be found in the [`application.yaml`](./application.yaml) template. 7 | 8 | Moreover the *pipeline itself* is defined in code, also using CloudFormation, and its definition is the [`pipeline.yaml`](./pipeline.yaml) template. The benefits of defining a CD pipeline in versioned source are the same as those for defining an application's deployment in source - automatibilty, visibility, etc. 9 | 10 | We define the pipeline in the same repository as the application itself - this is possible since AWS CodePipeline provides *CD as a service* - we do not need to manage any pipeline servers. Keeping the CD definition closely tied to the application definition allows us to make infrastructural changes quickly and simply. 11 | 12 | GitHub is an extremely popular location to host source code for applications, and this example uses GitHub as its source code location. We define the integration between AWS and GitHub solely within the Pipeline's template - no manual use of the AWS Console or CodePipeline API are required. 13 | 14 | As part of the GitHub integration we make use of CodePipeline's ["GitHub Webhook"](https://docs.aws.amazon.com/codepipeline/latest/userguide/pipelines-webhooks.html) feature to allow for executions that trigger more quickly, and that allow source event filtering. 15 | 16 | ![Example](images/githubpipeline.png "Example of a successful execution") 17 | 18 | ## How to create the pipeline 19 | 20 | 1. Fork this repository to your own GitHub repository 21 | 22 | 1. Update the `GitHubOwner` and `GitHubRepo` default parameter values in [`pipeline.yaml`](./pipeline.yaml) for your fork. 23 | 24 | 1. Create a new GitHub personal access token for this application. See [here](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/) for how to do this - CodePipeline needs just the `Read and Write access to repository hooks` permissions. I recommend you name the token for this particular pipeline, at least to get started, and that you store the token somewhere safe, like a password manager. 25 | 26 | 1. :warning: The user associated with the personal access token above **MUST** have administrative rights for the Github repo - either by being an owner of the repo, or having been granted admin privs. Simply having write access is not sufficient, because this template attempts to create a webhook in Github. If your user has insufficient privileges the pipeline creation process will fail, but will create an stranded / undeletable version of your application stack. 27 | 28 | 1. By default the application CloudFormation stack will be named `github-codepipeline-app`, and the CodePipeline stack will be named `github-codepipeline`. If / when you want to change these then update the following files, looking for references to `github-codepipeline` : 29 | * `application.yaml` 30 | * `create-pipeline.sh` 31 | * `update-pipeline.sh` 32 | * `pipeline.yaml` 33 | 34 | 1. Commit all your changes to source control 35 | 36 | 1. Now from a terminal run the following (this assumes the AWS CLI is installed and configured). Make sure the terminal is configured to use the AWS region where you want the pipeline itself to run (or override using the `--region` flag), and that it is configured to use the account where the pipeline and application will run. Provide the GitHub token value that you created in step 3. 37 | 38 | ``` bash 39 | $ ./create-pipeline.sh YOUR-GITHUB-TOKEN 40 | ``` 41 | 42 | Once you've run this last command then watch both the CloudFormation and then CodePipeline consoles to evaluate whether the process has been successful. You should have two new CloudFormation stacks - one for the pipeline and one for the application, and you should be able to see a new Pipeline in CodePipeline. 43 | 44 | To test everything, after the pipeline has successfully completed it's first run, check the S3 console to see whether the new application bucket (as defined in [`application.yaml`](./application.yaml)) has been created. 45 | 46 | ## How to update the pipeline 47 | 48 | When you need to update the application code or structure (as defined in [`application.yaml`](./application.yaml)), then simply pushing your changes to source control will be sufficient - CodePipeline references these files from source on every pipeline run. 49 | 50 | If you need to change the structure of the CodePipeline itself then run `update-pipeline.sh` with the same GitHub token argument that you ran with `create-pipeline.sh`. If you no longer have the token then create a new one and use that. 51 | 52 | ## Teardown 53 | 54 | :warning: Run these steps **in order**, otherwise you may end up with stranded resources: 55 | 56 | 1. Delete the application stack 57 | 1. Delete the artifact bucket created by the pipeline 58 | 1. Delete the pipeline stack 59 | 60 | ## Questions, Comments, Additions, Suggestions 61 | 62 | If you have any questions, comments, additions or suggestions please feel free to comment through GitHub, on twitter at [@mikebroberts](https://twitter.com/mikebroberts), or via email at mike@symphonia.io. 63 | 64 | If your company is looking for help using CodePipeline, CloudFormation, or architecture using AWS then please contact us at [Symphonia](https://www.symphonia.io/). 65 | 66 | ## TODO 67 | 68 | * Refine IAM permissions in pipeline.yaml 69 | -------------------------------------------------------------------------------- /application.yaml: -------------------------------------------------------------------------------- 1 | AWSTemplateFormatVersion: '2010-09-09' 2 | # *** Change this to something useful for you! 3 | Description: github-codepipeline-app 4 | 5 | # This is just here as an example resource 6 | 7 | Resources: 8 | ApplicationBucket: 9 | Type: AWS::S3::Bucket 10 | -------------------------------------------------------------------------------- /create-pipeline.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | # *** Change this to the desired name of the Cloudformation stack of 4 | # your Pipeline (*not* the stack name of your app) 5 | CODEPIPELINE_STACK_NAME="github-codepipeline" 6 | 7 | if [ -z ${1} ] 8 | then 9 | echo "PIPELINE CREATION FAILED!" 10 | echo "Pass your Github OAuth token as the first argument" 11 | exit 1 12 | fi 13 | 14 | set -eu 15 | 16 | aws cloudformation create-stack \ 17 | --capabilities CAPABILITY_IAM \ 18 | --stack-name $CODEPIPELINE_STACK_NAME \ 19 | --parameters ParameterKey=GitHubOAuthToken,ParameterValue=${1} \ 20 | --template-body file://pipeline.yaml 21 | -------------------------------------------------------------------------------- /images/githubpipeline.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/symphoniacloud/github-codepipeline/26871992bf17d45095c3d86404da375cfa869897/images/githubpipeline.png -------------------------------------------------------------------------------- /pipeline.yaml: -------------------------------------------------------------------------------- 1 | AWSTemplateFormatVersion: '2010-09-09' 2 | # *** Change this to something useful for you! 3 | Description: github-codepipeline 4 | 5 | Parameters: 6 | # *** This value must always be passed in when creating / updating stack 7 | # "NoEcho" is set to true, for security, so token won't be visible when examining the resulting stack 8 | GitHubOAuthToken: 9 | Type: String 10 | NoEcho: true 11 | MinLength: 93 12 | MaxLength: 93 13 | AllowedPattern: '[A-Za-z0-9_]*' 14 | 15 | # *** The remaining parameters should either be: 16 | # - overridden via changing "Default" here (PREFERABLE, since then they're in source control) 17 | # - or you can pass them in when creating / updating the stack 18 | 19 | # *** The owner of the Github repo for this application. 20 | GitHubOwner: 21 | Type: String 22 | Default: symphoniacloud 23 | AllowedPattern: "[A-Za-z0-9-]+" 24 | 25 | GitHubRepo: 26 | Type: String 27 | Default: github-codepipeline 28 | AllowedPattern: "[A-Za-z0-9-]+" 29 | 30 | GitHubBranch: 31 | Type: String 32 | Default: master 33 | AllowedPattern: "[A-Za-z0-9-]+" 34 | 35 | # *** The stack name for the actual application we're deploying 36 | ApplicationStackName: 37 | Type: String 38 | Default: github-codepipeline-app 39 | AllowedPattern: "[A-Za-z0-9-]+" 40 | 41 | Resources: 42 | PipelineArtifactsBucket: 43 | Type: AWS::S3::Bucket 44 | Properties: 45 | VersioningConfiguration: 46 | Status: Enabled 47 | 48 | CodePipeline: 49 | Type: AWS::CodePipeline::Pipeline 50 | Properties: 51 | ArtifactStore: 52 | Type: S3 53 | Location: !Ref PipelineArtifactsBucket 54 | RestartExecutionOnUpdate: true 55 | RoleArn: !GetAtt CodePipelineRole.Arn 56 | Stages: 57 | - Name: Source 58 | Actions: 59 | - Name: Source 60 | InputArtifacts: [] 61 | ActionTypeId: 62 | Category: Source 63 | Owner: ThirdParty 64 | Version: 1 65 | Provider: GitHub 66 | OutputArtifacts: 67 | - Name: SourceCode 68 | Configuration: 69 | Owner: !Ref GitHubOwner 70 | Repo: !Ref GitHubRepo 71 | Branch: !Ref GitHubBranch 72 | PollForSourceChanges: false 73 | OAuthToken: !Ref GitHubOAuthToken 74 | RunOrder: 1 75 | # Build and Deploy, etc., stages would follow.
