Libraries to help simplify Outreach manifests

Use Jsonnet to deploy to Kubernetes

To deploy to Kubernetes we use kubecfg, it natively supports jsonnet and helps simplify and standardize the way we build our manifests.

Install kubecfg

brew install kubecfg

Create your K8s manifest

You can use the jsonnet manifests in the concourse-example repo as an example:

https://github.com/getoutreach/concourse-example/blob/master/k8s/manifests/deployment.jsonnet

Render your K8s manifest

kubecfg \
--jurl http://k8s-clusters.outreach.cloud/ \
--jurl https://raw.githubusercontent.com/getoutreach/jsonnet-libs/master \
show deployment.jsonnet

Use Jsonnet to create a Concourse pipeline

We use Jsonnet to simplify and templatize our configurations, in this example we use it to create a concourse pipeline.

Install jsonnet

brew install jsonnet

Create a your Concourse pipeline

You can use the jsonnet pipeline in the concourse-example repo as an example:

https://github.com/getoutreach/concourse-example/blob/master/ci/pipeline.jsonnet

Render your Concourse pipeline

git clone git@github.com:getoutreach/jsonnet-libs.git /tmp/jsonnet-libs
jsonnet -J /tmp/jsonnet-libs -y pipeline.jsonnet

Testing

jsonnet files created under the ./tests directory can be used to test libsonnet functions. The files will be rendered to identically named .snap files in the same directory. Snapshots are regenerated each time the tests are run.

make test
