Continuous deployment of Endpoints

[Daniel Johns]

Is anyone able to point me in the direction of automated deployments for Endpoints and Appengine?

Appengine seems quite feasible but deploying the OpenAPI docs I can't see any examples of in my searches.

For reference I'm using Cloud endpoints Java Framework with Maven.

Assuming by "automated deployments" you're referring to a Continuous Integration and Delivery pipeline (CI/CD), I'd take a look at automating builds combining Terraform with your code version control system (e.g. git) containing both your application code and OpenAPI docs. Basically each release in your code repository should trigger a build that results in a set of deployment artifacts (Appengine bundle, OpenAPI doc, Terraform configuration, etc.) that are passed to terraform, which then actuates your infrastructure to match the state described by those artifacts.

I'd imagine there are plenty of examples floating around the internet doing this with Appengine alone; I'm not sure about examples with the Endpoints framework, but it's definitely possible (apologies if you were looking for actual real-life examples). Perhaps someone else in this group might have something like this. Good luck!

Thanks Josh.

I got it working with Bitbucket Pipelines using a custom docker image with cloudsdk and mvn installed. 

For others, this is the script which worked for me.

pipelines:

  default:

      - parallel:

        - step:
