Step 6. Initial rollout

Now that McDougals has tested Edgecell at their headquarters, they are now ready to test it at multiple stores.

Placements​

They pick 20 stores in Texas. They create a placement file for each location. This time they add more labels to provide information about the store that can be used for application deployment and configuration.

The 20 placement files look like this one.

apiVersion: edgecell.io/v1
kind: Placement
metadata:
  name:  3-mile-n-conway
  namespace: mcdougals.com
  uuid: 28c3487e-08bc-4bd1-bc1b-adbfc69336d4
  labels:
    env: prod
    isstore: true
    sales: XS
    posVersion: '2.1'
    region: 2
    candeliver: false
    canpickup: true
    city: Palmhurst
    country: US
    hasolopass: false
    id: 112830
    isavailable: true
    state: TX
    utcoffset: -6
    zip: '78573'
  annotations:
    telephone: (956) 583-2239
    address: |-
      McDougals Express
      220 East 3 Mile Rd
      Palmhurst, TX 78573
    url: https://mcdougals.com/store/3-mile-n-conway
spec:
  nodes:
    - type: edgecell.io/aa1
  localnetwork:
    type: dhcp
  location:
    longitude: -98.316177
    latitude: 26.257374

Schedules​

Each placement has a Schedule object since they are all being shipped directly to the stores.

apiVersion: edgecell.io/v1
kind: Schedule
metadata:
  name:  rolloutW20-1
  namespace: mcdougals.com
spec:
  week: 2023W20
  placements:
    - mcdougals.com/3-mile-n-conway
  telephone: (956) 583-2239
  address: |-
    McDougals Express
    220 East 3 Mile Rd
    Palmhurst, TX 78573

It is not as tedious as it may look. The VSCode extention generates most of the files with a command.

Release​

Once the nodes are shipped by the Provider and installed by the Deployer, they are ready to deploy apps to all locations. The following Release should deploy the dashboard app to all 20 stores.

apiVersion: edgecell.io/v1
kind: HelmRelease
metadata:
  name: mcdashboard-tx
  namespace: mcdougals.com
spec:
  interval: 5m
  selector:
    matchLabels:
      state: TX
      isstore: true
      env: prod
  chart:
    spec:
      chart: mcdashboard
      version: '>=1.0.0'
      sourceRef:
        kind: HelmRegistry
        name: mcdashboard
        namespace: mcdougals.com
      interval: 1m
  values:
    replicaCount: 2
