Installing Spinnnaker

Spinnkaer has a lot of pieces and parts. Below is a table listing everything. You don't need to know any of this for the workshop, but it's here for completeness.

Servivces Port Description
Deck 9000 Deck is a static AngularJS-based UI.
Clouddriver 7002 Cloud Driver integrates with each cloud provider (AWS, GCP, Azure, etc.). It is responsible for all cloud provider-specific read and write operations.
Echo 8089 Echo provides Spinnaker’s notification support, including integrations with Slack, Hipchat, SMS (via Twilio) and Email.
Front50 8080 Front50 stores all application, pipeline and notification metadata.
Gate 8084 Gate exposes APIs for all external consumers of Spinnaker (including deck). It is the front door to Spinnaker.
Igor 8088 Igor facilitates the use of Jenkins in Spinnaker pipelines (a pipeline can be triggered by a Jenkins job or invoke a Jenkins job)
Orca 8083 Orca handles pipeline and task orchestration (ie. starting a cloud driver operation and waiting until it completes).
Rosco 8087 Rosco is a packer-based bakery. We believe in immutable infrastructure and rosco provides a means to take a Debian or Red Hat package and turn it into an Amazon Machine Image. Don’t worry, it also supports Google Compute Engine and Azure images.
Fiat 7003 Fiat is the authorization server for the Spinnaker system. It exposes a RESTful interface for querying the access permissions for a particular user.

Install Helm

Navigate back to the spinnaker-k8s-workship dir

$ cd ..

Download and install helm binary From https://github.com/kubernetes/helm/blob/master/docs/quickstart.md

$ wget https://storage.googleapis.com/kubernetes-helm/helm-v2.4.2-linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf helm-v2.4.2-linux-amd64.tar.gz

Add Helm to PATH

$ export PATH=$PATH:/usr/local/linux-amd64

Initialize local CLI

$ helm init
$ helm repo update

Configure Spinnaker

First, update the values file with your project id and the current time.

$ sed -i.bak s/REPLACE_ME/$(gcloud info --format='value(config.project)')/g ./config/values.yaml
$ sed -i.bak s/TIMESTAMP/$(date +%s)/g ./config/values.yaml

Next, copy your service account credentials into values.yaml.

Copy the output from the following command into values.yaml, replacing <SERVICE_ACCOUNT_JSON>

$ SERVICE_ACCOUNT_JSON=$(cat account.json) && echo $SERVICE_ACCOUNT_JSON

TODO: Make this a sed operation

$ nano ./config/values.yaml 
# Disable minio the default
minio:
  enabled: false
 
# Enable gcs
gcs:
  enabled: true
  project: <my-project-name>
  jsonKey: '<SERVICE_ACCOUNT_JSON>'
 
# Name has to be unique in GCS.
storageBucket: <my-project-name>-spinnaker 
 
# Configure your Docker registries here
accounts:
- name: gcr
  address: https://gcr.io
  username: _json_key
  password: '<SERVICE_ACCOUNT_JSON>'
  email: [email protected]

Deploy Spinnaker Chart

Install spinnaker

NOTE: This is going to take a while.

$ helm install stable/spinnaker --name cd -f ./config/values.yaml --timeout 600

In another tab, you can monitor the progress of the installation. Errors will happen this is to be expected while the pods sync up.

$ kubectl get pods -w

Access the spinnaker UI

$ DECK_POD=$(kubectl get pods -l "component=deck,app=cd-spinnaker"  \
    -o jsonpath="{.items[0].metadata.name}")
$ kubectl port-forward $DECK_POD 9000 >>/dev/null &

Visit the Spinnaker UI by opening your browser to: http://127.0.0.1:9000

Misc / Monitor Progresss / Troubleshoot / Debug Installation

Everything in this helm chart will be labeled cd-spinnaker, so you can search for things like:

$ kubectl get deployment -l app=cd-spinnaker

NOTE: If you want to make a quick change. Helm can do a blue green deployment via upgrade.

$ helm upgrade cd stable/spinnaker -f updated-values.yaml

Debugging can be done with

$ kubectl logs <pod name>

TODO: Move this somewhere else. To delete everything

$ helm delete cd --purge

get the latest list of charts

$ helm repo update

Common problems Front50 will fail if the GCS bucket name is not unique.
