Upgrading a Canary Service/Deployment

Upgrading a deployment/canary service is done by specifying the image hash value and putting it on the canary service. This affects the active canary service. See below for examples.

Update active canary service:

POST /services
{
    "selector": "green"
}

...

If the active service is already the selector given, then a message telling the user is provided:

...

Before:

iiq-wp-platform git:(dev) kc get configmap -n wp-platform -o yaml
apiVersion: v1
items:
- apiVersion: v1
  data:
    canaryEnv: '{"selector":"blue","image":"961406424767.dkr.ecr.us-west-2.amazonaws.com/rezfusion-cloud:dev"}'
  kind: ConfigMap
  ...

...

POST /sites/create
{
    "id": "gggrrr",
    "hostnames": ["gggrrr.cloud2-stg.rezfusion.com"],
    "service": "blue",
    "name": "Project Bluelaunch | GGGrrr",
    "canonicalHostname": "gggrrr.cloud2-stg.rezfusion.com"
}

This will create the AWS Dynamo DB entry for the site as well as relevant secrets for accessing the database and WP CMS.

Fetching Site Details

Site details can be viewed by running a GET request against /sites/rrr:

GET /sites/{site-id}

...

Provision

After creating a site, it is able to be provisioned. Provisioning a site means that an actual site instance, along with relevant databases created, S3 bucket subdirectories, etc. for the site to use. This endpoint kicks off the installation of a WP site, a job to add an Ingress entry, and a job to activate the desired theme for a given site.

...

Assuming all goes well, a site should be visible at the hostname configured during /sites/create within 5-10 minutes.
