Question: Is it possible for TeamCity to integrate to JIRA like how Bamboo integrates to JIRA? I couldnt find any documentation on JetBrains website that talks about issue-tracker integration.

FYI: I heard that TeamCity is coming out with their own tracker called Charisma. Is that true?

Answer: 
TeamCity does not have extensive integration with JIRA as Bamboo does, and I am not aware of a plugin that provides it. TeamCity does however, offer a generic integration option to external sites which can be used for basic JIRA integration. 

From their documentation:

> 
> TeamCity allows to map patterns in VCS change comments to arbitrary HTML pieces using regular expression search and replace patterns. One of the most common usages is to map an issue ID mentioning into a hyperlink to the issue page in the issue tracking system.

I haven't set this up yet on our local TeamCity, so I can't testify as to how well it works.
TeamCity does have a free plugin for Atlassian Confluence. Its provides a nice way to show your build status on your wiki.

You can find it in the Atlassian marketplace:
