Set up redis service automatically

[aimfeld]

While the DB container worked out of the box, the redis container was missing. I got it running quickly with ddev get drud/ddev-redis. The PLATFORM_RELATIONSHIPS variable was missing the configuration for the redis service defined in services.yaml, so I had to create a fallback. Would be great if this works out of the box.

.platform.app.yaml

relationships:
  database: "mysql:mysql"
  rediscache: "cacheredis:redis"

services.yaml

mysql:
  type: mysql:10.5
  disk: 4096
cacheredis:
  type: redis:6.2

redis config

$platformRelationships = json_decode(base64_decode(getenv('PLATFORM_RELATIONSHIPS')));

return [
    'redis'   => [
        'host' => $platformRelationships['rediscache'][0]['host'] ?? 'redis', // Fallback for DDEV
        'port' => $platformRelationships['rediscache'][0]['port'] ?? 6379, // Fallback for DDEV
    ],
]

Thanks @aimfeld - Would you be willing to put your .platform.app.yaml and .platform/services.yaml here (or in a gist on gist.github.com)? Perhaps edited.

Thanks so much. I imagine the failure was a result of
