gitlab-runner

We are going to deploy a stand for testing the CI chain in GitLab, but there are concerns that we will not meet the GitLab-ru ... itlab itself, I did not find the answer I needed. Tell me how to view or at least find the info how many runners can be used?

Authorization in repositories by ssh-key. I'm trying to put a tag on the current commit with the package version at the end o ... the list of Deploy Keys. Prdeposition is also that it is because the runner is already registered and he does not need a key?

I need to set up a project deployment to the server via ssh. Generated the ssh key and wrote the following script .gitlab-ci. ... t can run this job. Go to Runners page In the settings section, there are several views, how and which one should be created?
