Spinnaker Summit 2020

Run Jobs

Using Spinnaker Run jobs one can run tasks like updating a database, interacting with third-party systems like Jira or ServiceNow, run tests and even builds! In this example, the run job does a maven build on a git repo, builds a docker image using kaniko and finally deploys the built image.

Resources

pipeline.json

The json representation of the pipeline used in the demo

src/*

The source code of a simple application

deploy.yaml

Kubernetes manifest to deploy the simple application

Dockerfile

Creating secret for kaniko

Use the config.json. Update the auth to the correct value. For Dockerhub it is:

echo -n USER:PASSWORD | base64

And the file as a secret into kubernetes:

kubectl create secret generic kaniko-secret --from-file=<path to config.json>

More information on Kaniko can be found in https://github.com/GoogleContainerTools/kaniko/blob/master/README.md
