## TLS support
Gitaly supports TLS credentials for GRPC authentication. To be able to communicate
with a gitaly instance that listens for secure connections you will need to use `tls://` url
scheme in the `gitaly_address` of the corresponding storage entry in the gitlab configuration.
### Example TLS configuration
Omnibus installations:
```ruby
# /etc/gitlab/gitlab.rb
git_data_dirs({
'default' => { 'path' => '/mnt/gitlab/default', 'gitaly_address' => 'tls://gitaly.internal:8075' },
'storage1' => { 'path' => '/mnt/gitlab/storage1', 'gitaly_address' => 'tls://gitaly.internal:8075' },
})
gitlab_rails['gitaly_token'] = 'abc123secret'
```
Source installations:
```yaml
# /home/git/gitlab/config/gitlab.yml
gitlab:
repositories:
storages:
default:
path: /mnt/gitlab/default/repositories
gitaly_address: tls://gitaly.internal:8075
storage1:
