Multi-tenant support for Kiwi TCMS
Project description
Introduction
This package provides multi-tenant support for Kiwi TCMS and is a wrapper around django-tenants. You can use it to host different organizations on the same application server or host multiple product instances used by different teams. Each tenant is able to see only the information created by themselves.
Installation
IMPORTANT: multi-tenancy is backed by PostgreSQL schemas! It will not work with a different database backend.
WARNING: current tenant is decided based on the FQDN by which you are accessing Kiwi TCMS!
The following changes need to be introduced into a downstream Docker image or your Python virtualenv where the main Kiwi TCMS instance is hosted:
pip install kiwitcms-tenants
then make sure KIWI_TENANTS_DOMAIN ENV variable is specified !!! The rest of the settings are installed into tcms_settings_dir/multi_tenant.py and Kiwi TCMS will pick them up automatically!
First boot configuration
When starting your multi-tenant Kiwi TCMS instance for the first time you also need to create information about the so called public tenant. That is the default tenant on which your application runs:
./manage.py initial_setup
Your tenant will be available at https://$KIWI_TENANTS_DOMAIN! Other tenants can be created via the web interface and will be available under team-01.$KIWI_TENANTS_DOMAIN, product-02.$KIWI_TENANTS_DOMAIN, etc depnding on the actual schema name you give them.
DNS configuration
You need wildcard DNS resolution to be configured for *.tenants.example.org!
If using AWS Route 53 create an A record with Name==*.tenants for the example.org domain and point it to the IP address of your Kiwi TCMS instance.
Once DNS has been configured you should be able to query for various domains with tools like dig and nslookup:
$ dig public.tenant.kiwitcms.org ; <<>> DiG 9.11.4-P2-RedHat-9.11.4-12.P2.el7 <<>> public.tenant.kiwitcms.org ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58543 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;public.tenant.kiwitcms.org. IN A ;; ANSWER SECTION: public.tenant.kiwitcms.org. 36 IN A 100.24.231.234 ;; Query time: 35 msec ;; SERVER: 10.38.5.26#53(10.38.5.26) ;; WHEN: Tue Nov 19 14:04:09 EET 2019 ;; MSG SIZE rcvd: 71 $ nslookup linux.tenant.kiwitcms.org Server: 10.38.5.26 Address: 10.38.5.26#53 Non-authoritative answer: Name: linux.tenant.kiwitcms.org Address: 100.24.231.234
All sub-domains should resolve to the same IP address!
Migrating Single-Tenant to Multi-Tenant
See Migrating Single-Tenant to Multi-Tenant section in the official django-tenants documentation! It has been contributed by the Kiwi TCMS team and that was the procedure we’ve used to migrate the previous demo website (ST) to its new MT version!
Local Development
Starting with Kiwi TCMS v13.1 session and CSRF cookies are configured only on HTTPS connections which will prevent browsers from sending cookies over a plain text HTTP connection. This will result in not being able to login if you are using a local development server. To workaround this issue, first generate an SSL certificate:
/usr/bin/sscg -v -f --country BG --locality Sofia --organization "Kiwi TCMS" --organizational-unit "QA" --ca-file ssl/ca.crt --cert-file ssl/host.crt --cert-key-file ssl/host.key
Then use the runerver_plus command to start Kiwi TCMS development server with HTTPS:
PYTHONPATH=../Kiwi/ KIWI_TENANTS_DOMAIN=tenant.example.bg ./manage.py runserver_plus --cert-file ssl/host.crt --key-file ssl/host.key
Then point your browser to https://tenant.example.bg:8000/. The SSL warning from the browser is expected!
You can use your OS hosts file to configure DNS resolution during development:
127.0.0.1 localhost tenant.example.bg empty.tenant.example.bg
