I want to start using Redmine with Gitlab for issue tracking.
Is there a way to update the gitlab configuration (gitlab.yml) with the redmine urls and start using both applications without having to bundle Gitlab again?
Not exactly.
There is a Redmine plugin which does the opposite: "Gitlab Merge Request"
This plugin allow you to add a "New merge request" link on redmine issue.
Gitlab merge request form will be filled based on project configuration
And there is a (closed) feature request issue 97 asking for using Redmine is recommended for Issue management (again the opposite of what you are asking for)
However, this feedback request is closer:
I currently use Redmine for my issues in oreder to do time-tracking, gantt, versions, guest access.
I think it would be cool to allow setup for Redmine issues to be synced into Gitlab and possibly vice versa.You can now link Redmine issues from GitLab: see
gitlab.yml.example
.
## External issues trackers
issues_tracker:
# redmine:
# title: "Redmine"
# ## If not nil, link 'Issues' on project page will be replaced with this
# ## Use placeholders:
# ## :project_id - GitLab project identifier
# ## :issues_tracker_id - Project Name or Id in external issue tracker
# project_url: "http://redmine.sample/projects/:issues_tracker_id"
So it doesn't replace Redmine issue management with GitLab's, but it helps keeping the two in sync.
