Much of the default configuration in Hyku is set up to use multi-tenant mode. This default mode allows Hyku users to run the equivielent of multiple Hyrax installs on a single set of resources. However, sometimes the subdomain splitting multi-headed complexity is simply not needed. If this is the case, then single tenant mode is for you. Single tenant mode will not show the tenant sign up page, or any of the tenant management screens. Instead it shows a single Samvera instance at what ever domain is pointed at the application.
To enable single tenant, set HYKU_MULTITENANT=false in your docker-compose.yml and docker-compose.production.yml configs. After changinig this setting, run rails db:seed to prepopulate the single tenant.
In single tenant mode, both the application root (eg. localhost, or hyku.test) and the tenant url single.* (eg. single.hyku.test) will load the tenant. Override the root host by setting HYKU_ROOT_HOST`.
To change from single- to multi-tenant mode, change the multitenancy/enabled flag to true and restart the application. Change the 'single' tenant account cname in the Accounts edit interface to the correct hostname.
Hyku currently only supports the configuration of one Google Analytics account for the basic functionality of this feature. Hyku currently only support Google Analytics with the Universal Analytics property for this feature.
Note: Google has announced they will stop processing data using the Universal Analytics property on July 1, 2023 or July 1, 2024 for Analytics 360 properties.
To enable analytics tracking and reporting features within Hyku, please follow the directions below.
- Create a Service Account: https://cloud.google.com/iam/docs/creating-managing-service-accounts
- Note the service account email
- When making a service account key, make sure the key type is set to p12
- Note the service account private key secret
- Create an OAuth 2.0 Client ID: https://developers.google.com/identity/protocols/oauth2/web-server#creatingcred
- Create an Analytics account: https://support.google.com/analytics/answer/10269537?hl=en
- Note Google Universal Analytics ID number
- Add service account email as User, and grant "View" access: https://support.google.com/analytics/answer/1009702?hl=en#Add&zippy=%2Cin-this-article
- Enable the "Google Analytics API": https://developers.google.com/identity/protocols/oauth2/web-server#enable-apis
- Enable the "IAM Service Account Credentials API": https://developers.google.com/identity/protocols/oauth2/web-server#enable-apis
In Hyku there are a few areas to set the environment variables needed for each of your environments development/staging/prodeuction/etc.
- Uncomment the config/analytics.yml file where the below mentioned environment variables will connect to our application.
analytics:
google:
analytics_id: <%= ENV['GOOGLE_ANALYTICS_ID'] %>
app_name: <%= ENV['GOOGLE_OAUTH_APP_NAME'] %>
app_version: <%= ENV['GOOGLE_OAUTH_APP_VERSION'] %>

privkey_secret: <%= ENV['GOOGLE_OAUTH_PRIVATE_KEY_SECRET'] %>
client_email: <%= ENV['GOOGLE_OAUTH_CLIENT_EMAIL'] %>- For local development please see the .env file and see the "Enable Google Analytics" section.

value: 'true'To get the GOOGLE_OAUTH_PRIVATE_KEY_VALUE value to set the variable in GitHub's Environment Secrets, you need the path to the p12 file you got from setting up your Google Service Account and run the following in your console locally.
base64 -i path/to/file.p12 | pbcopy
Once you run this script the value is on your local computers clipboard. You will need to paste this into GitHubs Environment Secrets or however you/your organization are handling secrets.
You can log all of the I18n lookups to the Rails logger by setting the I18N_DEBUG environment variable to true. This will add a lot of chatter to the Rails logger (but can be very helpful to zero in on what I18n key you should or could use).
$ I18N_DEBUG=true bin/rails serverYou can upload your primary works to S3 in Valkyrie mode by turning on REPOSITORY_S3_STORAGE and setting the accompanying bucket and credentials variables. This enables both AWS S3 and other S3 like storage engines such as Minio. As of this writing this only affects Valkyrie resources and only the primary storage. Derivatives, uploads and branding assets all still go to the shared storage directories.
