Running the stack
For development / testing with Docker
Dory
On OS X or Linux we recommend running Dory. It acts as a proxy allowing you to access domains locally such as hyku.test or tenant.hyku.test, making multitenant development more straightforward and prevents the need to bind ports locally. Be sure to adjust your ~/.dory.yml file to support the .test tld. You can still run in development via docker with out Dory. To do so, copy docker-compose.override-nodory.yml to docker-compose.override.yml before starting doing docker-compose up. You can then see the application at the loopback domain 'lvh.me:3000'.
gem install dory
dory upBasic steps
docker-compose up webThis command starts the whole stack in individual containers allowing Rails to be started or stopped independent of the other services. Once that starts (you'll see the line Passenger core running in multi-application mode. to indicate a successful boot), you can view your app in a web browser with at either hyku.test or localhost:3000 (see above). When done docker-compose stop shuts down everything.
Tests in Docker
The full spec suite can be run in docker locally. There are several ways to do this, but one way is to run the following:
docker-compose exec web rakeWith out Docker
Please note that this is unused by most contributors at this point and will likely become unsupported in a future release of Hyku unless someone in the community steps up to maintain it.
For development
solr_wrapper
fcrepo_wrapper
postgres -D ./db/postgres
redis-server /usr/local/etc/redis.conf
bin/setup
DISABLE_REDIS_CLUSTER=true bundle exec sidekiq
DISABLE_REDIS_CLUSTER=true bundle exec rails server -b 0.0.0.0For testing
See the Hyku Development Guide for how to run tests.
Working with Translations
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 serverOn AWS
AWS CloudFormation templates for the Hyku stack are available in a separate repository:
With Docker
We distribute two docker-compose.yml configuration files. The first is set up for development / running the specs. The other, docker-compose.production.yml is for running the Hyku stack in a production setting. . Once you have docker installed and running, launch the stack using e.g.:
docker-compose up -d webNote: You may need to add your user to the "docker" group.
newgrp dockerWith Vagrant
The samvera-vagrant project provides another simple way to get started "kicking the tires" of Hyku (and Hyrax), making it easy and quick to spin up Hyku. (Note that this is not for production or production-like installations.) It requires VirtualBox and Vagrant.
With Kubernetes
Hyku relies on the helm charts provided by Hyrax. See Deployment Info for more information. We also provide a basic helm deployment script. Hyku currently needs some additional volumes and ENV vars over the base Hyrax. See (ops/review-deploy.tmpl.yaml) for an example of what that might look like.
Single Tenant Mode
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.
Switching accounts
There are three recommend ways to switch your current session from one account to another by using:
switch!(Account.first)
# or
switch!('my.site.com')
# or
switch!('myaccount')Analytics Feature
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.
Setup a Google Analytics Account
- 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
Set the Environment Variables
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_path: <%= ENV['GOOGLE_OAUTH_PRIVATE_KEY_PATH'] %>
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.

Development Dependencies
Postgres
Hyku supports multitenancy using the apartment gem. apartment works best with a postgres database.
Importing
Bulkrax:
Bulkrax is enabled by default and CSV, OAI and XML importers can be used in the admin dashboard or through the command line API. More info about configuring and using bulkrax can be found here
Commandline Importers
Importing from CSV and PURL directly can be done via Bulkrax and the built in code in Hyku is slated for deletion in the next release.
Compatibility
- Ruby 2.7 is recommended. Later versions may also work.
- Rails 5.2 is required.
