Continuous Delivery at OLX (part III)

On the tooling part, we have developed, besides Octopush, a very simple web app, called TagReporter, where we track & show everyone what version of components are deployed on each environment (components on the rows, envs on columns, links takes the user to JIRA, Github or JFrog). 

Additionally we provide information on the Release JIRA ticket that was or is about to be deployed LIVE and its current status. The last column provides different actions according to the logged user profile, devs can create tickets automatically and Release Engineers can trigger deployments/rollbacks. The app integrates all this tools via REST API, providing a Transactional deployment service: it calls jenkins (triggering deploys), interacts with JIRA (creating and transitioning tickets) and reports to IRC (notifying beginning or start of deployments).
Deployments scripts report back to TagReporter with the Component, version and environment where it has just deployed.
Since the tool saves all this information, it also provides reports of  historical deploys, allowing all kind of filters.
We used Hubot for IRC interactions, not only for notifications but also to ask him things like versions deployed in different servers or settings values. 
Finally our DBA team has developed a tool for tracking and running SQL scripts, devs commit scripts to Git (using Pull request to have them reviewed) and the tool runs them.
