Canary Endpoints:

Code Block
languagego

  • Install - runs wp core install... against the actively provisioning site.

  • ActivateTheme - runs wp theme install --activate {theme-name} against the actively provisioning site.

  • Ingress - adds an Ingress hosts entry for the given site.

  • FlushCaches - runs wp cache flush against the given site.

  • PatchIngress - updates an Ingress host entry for a given site. This will point the given site’s ingress handler to the active canary service. Usually used within the context of a promotion.

  • PatchService - patches a site’s service value within the sites repository to reflect the active Canary service the site was moved to.

Code Block
POST /sites/create
{
    "id": "rrr",
    "theme": "astra",
    "hostnames": ["rrr.cloud2-stg.rezfusion.com"],
    "service": "blue",
    "name": "Project Bluelaunch | rrr",
    "canonicalHostname": "rrr.cloud2-stg.rezfusion.com"
}

Fetching Site Details

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

...

Code Block
PUT /sites/{site-id}/upgrade

...

Site originally provisioned on blue service. Active Canary service set to green.
...
Image Added
Now, the service on the site is green:
...
A related job to flush the cache is also executed against ttt:
...
Promote
Promoting, almost identical to upgrading, moves a site to the active Canary service. Additionally, this triggers several queued jobs on the given site after moving to the new image. 
...
To roll an upgrade or promotion out for all sites on a given service, simply execute a PUT request against the /services endpoint. These request types affect all sites on the active canary service. The only differences between the two requests is the promote value. When false, this request triggers a new upgrade pipeline for all sites on the active canary service. 
If promote is true, then the promote pipeline is executed against each site on the active canary service. The promote pipeline includes an additional step to patch the ingress.
