Provide a translation check site for translators


Provide a means for translators for easily checking the translations imported from the translation system in a production like environment.

Problem Description

Translators and translation reviewers need a way to verify that translation behaves correctly when applied to the OpenStack Dashboard and its plug-ins. This also helps when context information is missing from a string, for example if “Search” is a label or a button, because in some cases the translations have to be different. Now a translator has to run their own DevStack instance, fetch the updated translation, run the build, etc - which is cumbersome, requires skills outside the translation ones and duplicates a lot of work between every translation group.

Proposed Change

A sample OpenStack instance should be provided to translators, which runs the current working branch and regularly fetches updated translations. The instance should run Horizon and every module supported by the stock dashboard. This could be achieved with openstack-ansible AIO. AIO means “all in one”. OpenStack components are installed in separate container (i.e. Horizon) on a single VM. Advantages for containers are: easy to manage (i.e. snapshot backup and recovery in case of failed updates of the horizon container). openstack-ansible itself is reboot-save. It’s not necessary to re-install from scratch like DevStack. In the Horizon container a script is installed to fetch the translation file periodically from the translation server via cron, compile it and serves the new content to the dashboard. The dashboard contents the core functionality plus core plugins. The instance should be able to spawn pseudo VMs that are using fakevirt driver, create networks and all other capabilities provided by Horizon, but should be firewalled off from the rest of the world with a periodic cleanup of all resources. There is no need for SSO integration as the only required accounts are a shared admin and a user account, with the credentials known to the translation team. The sync cycle of the translation files is configurable. Update mechanism for different branches or releases of the dashboard are also configurable and done by ansible. The installed AIO should upgraded 4 times each cycle: soft/hard string freeze, release, stable.


As an alternative a prebuilt VM image could be created for the translators to run on their own workstations or cloud with a manual run of ansible playbooks for update Horizon or sync the translation files.

Gerrit Topic

Use Gerrit topic “i18n-checksite” for all patches related to this spec.

git-review -t i18n-checksite

Work Items

  • Create puppet module for creating and spawning instance

  • Create firewall and networking rules, only HTTPS for the dashboard




A new server will have to be created with sufficient resources to run all the required components and at least a few cirrus virtual machines.

DNS Entries

There should be a new DNS entry created for easy access by the translation teams.


Documentation related to configuration and potential AIO debugging for the infrastructure team in the system-config repository.

Documentation for translators who will be using this.


Security issues should be taken into consideration, as the dashboard allows the creation of new networks, floating IP addresses, load balancers and instances. However, as long as fake virt driver is used, these security concerns disappear.


A basic set of functional tests and monitoring should be set up, for example if the environment recreation completed successfully and every service runs correctly.


This will require extension of openstack-ansible-os_horizon
