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 t the loopback domain 'lvh.me:3000'.

gem install dory
dory up

Basic steps

docker-compose up web

This 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 rake

Docker with an M1 chip

You may run into issues with Selenium with an M1 chip. If so, use the override file provided called docker-compose-override.yml
To see selenium grid running in the browser and check that selenium is connected properly, visit localhost:4444
To see selenium tests running in the browser, you will need a VNC. Macs have a built in VNC app called Screen Sharing.
- Spotlight search: open Screen Sharing app
- enter the following address to watch your tests: vnc://localhost:6900
- if prompted for a password, the default is "secret"
- you should now be able to see selenium tests run in the browser.

With 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 0.0.0.0

For 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 server

On AWS

AWS CloudFormation templates for the Hyku stack are available in a separate repository:

https://github.com/hybox/aws

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 web

Note: You may need to add your user to the "docker" group.

newgrp docker

With 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

Analytics is comprised of two aspects:

Sending data to the analytics end-point
Fetching and reporting data from the analytics end-point

For a more exhaustive discusion, see Resolve Sending Google Analytics Data for Tenant and Proprietor · Issue #910 · scientist-softserv/palni-palci.

Google

Both the sending and fetching functionality require that you create a Service Account. But only the fetching functionality requires that you set the OAuth credentials.

The fetching aspect is configured at the proprietor level via environment variables. See ./config/analytics.yml.

The sending aspect can be configured at both:

the proprietor level, via the ./config/analytics.yml mentioned above.
the tenant level by going to the tenant's Dashboard >> Settings >> Account

Analytics tracking and reporting features will be turned off by default. To enable them 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 Analytics 4 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

Proprietor Level Configuration

Below is a table describing the named variable.

Name	Description
`GOOGLE_ANALYTICS_ID`	The ID of your Google Analytics account.
`GOOGLE_OAUTH_APP_NAME`	The name of the Google application in the Google API console.
`GOOGLE_OAUTH_APP_VERSION`	The version of the Google application in the Google API console.
`GOOGLE_OAUTH_PRIVATE_KEY_VALUE`	The value of the p12 file with base64 encryption.
`GOOGLE_OAUTH_PRIVATE_KEY_PATH`	The full path to your p12, key file.
`GOOGLE_OAUTH_PRIVATE_KEY_SECRET`	The secret provided when you created the p12 key.
`GOOGLE_OAUTH_CLIENT_EMAIL`	OAuth Client email address.

To get the GOOGLE_OAUTH_PRIVATE_KEY_VALUE value, you need the path to the p12 file you got from setting up your 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 the corresponding account setting.
You can use the GOOGLE_OAUTH_PRIVATE_KEY_VALUE OR GOOGLE_OAUTH_PRIVATE_KEY_PATH value. VALUE takes precedence.

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.
