github serverless dotnet artifacts

Publish and deploy serverless dotnet projects using github managed artifacts.

Serverless packaging is performed correctly.

Requirements

• yarn, gh & dotnet are available on the command line
• Amazon.Lambda.Tools dotnet tool is installed in the target dotnet repo:

$ dotnet new tool-manifest
$ dotnet tool install Amazon.Lambda.Tools

Usage

1. Install

$ yarn add -D @totallymoney/github-serverless-dotnet-artifacts

2. Specify this package location in your serverless.yml

package:
  artifact: package.zip

3. Add a publish step to your CI pipeline to create a github release

$ yarn run gsda-publish $VERSION [ -p path/to/project ]

• $VERSION is the github release name in semver format
• -p is optional with a default value of ./src

4. Use the deploy command to update an enviroment

$ yarn run gsda-deploy $VERSION $ENVIRONMENT

• $VERSION is the github release to deploy
• $ENVIRONMENT is the target environment (aka serverless 'stage')

5. Add a helper script to your package.json and use pick for interactive deployments!

"scripts": {
  "pick": "gsda-pick -e stage -e prod -c 5"
}

$ yarn pick

• -e (multiple) are preset environments for pick
• -c is the version list count for pick
• both -e and -c have sensible defaults and can be overridden when pick is called

Development

Make sure you belong to the totallymoney npm organization. Then make changes to the source code and publish. Enter the new version number as prompted. A git push command will run automatically after publishing.

$ git commit -am "Improve logging"
$ yarn publish --access public

Migrating from 3.x.x to 4.x.x

• github cli is required on your machine.

  $ brew install gh
  # start interactive setup
  $ gh auth login

• The deploy & publish npm scripts are now obselete.

  Even in 3.x.x, these commands only existed as a level of indirection to centralize input that could be called from more than one place and be burdensome to type. These commands are now less of a burden because the gh cli automatically recognises the repo it is operating on. We no longer need to "pin" the repo name with deploy & publish indirection commands, and can instead go straight to gsda-deploy|publish. We should, however, favour gsda-pick to manually deploy from the command line over gsda-deploy. gsda-pick now uses gsda-deploy internally, and no longer expects deploy to exist.

  The positional arguments of gsda-deploy remain the same: version, then target environment. So if deploy is called by CI tooling, the only change required is to use gsda-deploy instead.

  The removal of publish also avoids any confusion caused by "squatting" on the existing (npm|yarn) publish command.

• The project path of the gsda-publish command is provided via the optional -p flag.

  If not specified, the project path defaults to ./src which is the case for most projects. The version argument is still the first positional argument expected by gsda-publish. The command should be called directly from CI tooling, and called directly from the command line if ever needed outside of a CI context.

• The commit hash positional argument to the gsda-publish command is obselete.

  Again, gh understands the context and will create a release from the current state of the repo, which will be checked out at the commit we wish to tag.

• If building with CircleCI the github-cli orb is required.
