Intro

CI/CD with OpenFaaS¶

Due to the fact that OpenFaaS functions are built into portable Docker images you can use any container builder to build your functions. The faas-cli can be used to build, push and deploy your functions.

Use the native `faas-cli`¶

It is recommended to use the faas-cli binary for building and deploying your functions whether that is to Kubernetes or faasd.

Build only:
```
faas-cli build
```
Build only & push:
```
faas-cli build
faas-cli push
```
To combine build, push and deploy:
```
faas-cli up
```

You can also use --parallel or / --filter when you have multiple functions in your stack.yml file.

The --shrinkwrap flag

The faas-cli build command invokes the docker CLI with the various flags and parameters required. If you want to use an alternative builder you can use the --shrinkwrap flag to generate a folder named ./build/<function> which can then be used with any other container builder such as BuildKit or Kaniko.

Building via REST API¶

Customers of OpenFaaS Pro can make use of our in-cluster builder.

Send your code as generated with faas-cli build --shrinkwrap to the /build endpoint of the OpenFaaS Pro builder and receive a JSON response with build logs and a URL to the published image.

GitHub Actions¶

GitHub Actions coupled with GitHub Container Registry is a fast and efficient way to build functions from public or private without hosting additional infrastructure.

We provide a complete multi-arch example in Serverless For Everyone Else.

GitLab¶

GitLab is a source-control management system which is offered on a SaaS or self-hosted basis.

You can find a GitLab pipeline example on the GitLab CI/CD page.

GitHub¶

For GitHub you can build with any suitable CI tool such as:

It's really up to you.
