Running Kaui locally
Note: use Ruby, not JRuby, for running the app locally.
You can run Kaui locally by using the test/dummy app provided:
export RAILS_ENV=development DB_HOST=127.0.0.1 DB_USER=root DB_PASSWORD=root DB_PORT=3306 bundle install bundle exec rails db:migrate bundle exec rails s
The Kill Bill URL can be configured through the
KILLBILL_URL environment variable, e.g.
Mounting Kaui into your own Rails app
The Kaui gem comes with a
kaui script to mount it in your existing Rails app.
Kaui expects the container app to define the current_user method, which returns the name of the logged-in user. This is used by Kill Bill for auditing purposes.
Migrations can be copied over to your app via:
bundle exec rake kaui:install:migrations
Finally, a Kill Bill server needs to be running for Kaui to fetch its information (see the Configuration section below). The default login credentials are admin/password. Users, Credentials, Roles and Permissions are passed through to Kill Bill. It uses Basic Auth by default, but the backend is pluggable (LDAP, ActiveDirectory, etc.).
Note: functional and integration tests require an instance of Kill Bill to test against.
Working with the kaui script
In order to generate the Rubygems-friendly
kaui script, you need to build the gem
and install it locally.
First, build the gem in the
Then, install and run it from a local directory:
mkdir foo gem install pkg/kaui-*.gem -i foo GEM_PATH=$PWD/foo:$GEM_PATH ./foo/bin/kaui /path/to/rails/app --path=$PWD --skip-bundle
Alternatively, you can run the
kaui script under
bin by setting your loadpath correctly:
ruby -Ilib bin/kaui /path/to/rails/app --path=$PWD --skip-bundle
To trigger a release, run (update
patch as needed):
bundle exec gem bump -c -p -t -v patch
- Update the
- Commit the changes
- Create the new tag and push the changes
GitHub Actions will automatically push the new gem to Rubygems.
KAUI has been enhanced to support multi-tenancy. In order to benefit from that mode, remove the properties
KillBillClient.api_secret from the config/initializers directory.
Admin User Roles
In multi-tenancy mode, there are two kinds of users:
- The multi-tenant admin user, which has the rights to configure the tenant information (creation of tenant, add allowed users for specific tenant, upload catalog, ...)
- The per-tenant admin user, which operates just a given tenant
Those roles and permissions are defined the same way other permissions are defined: The Shiro configuration (static config file, LDAP) in Kill Bill, will determine for each user its associated role, and the roles will have a set of available permissions. The new permissions have been created:
The enforcement in KAUI is based on the CanCan gem.
KAUI has been enriched with new models and new screens to manage the multi-tenancy, and those are available for the multi-tenant admin user:
kaui_tenantstable will list the available tenants (from KAUI point of view); note that this is redundant with the Kill Bill
tenantstable, and the reason is that the
api_secretneeds to be maintained in KAUI as well, so listing the existing tenants from Kill Bill would not work since that key is encrypted and cannot be returned. A new screen mounted on
/admin_tenantsallows to configure new tenants. The view allows to create the new tenant in Kill Bill or simply updates the local KAUI config if the tenant already exists.
kaui_allowed_userstable along with the join table
kaui_allowed_user_tenantswill list all the users in the system that can access specific tenants. The join table is required since a given user could access multiple tenants (e.g multi-tenant admin user), and at the same time many users could access the same tenant. A new screen mounted on
/admin_allowed_usersallows to configure the set of allowed users associated to specific tenants.
