# GitLab CI/CD instance configuration **(FREE SELF)**
GitLab administrators can manage the GitLab CI/CD configuration for their instance.
## Disable GitLab CI/CD in new projects
GitLab CI/CD is enabled by default in all new projects on an instance. You can set
CI/CD to be disabled by default in new projects by modifying the settings in:
- `gitlab.yml` for source installations.
- `gitlab.rb` for Omnibus GitLab installations.
Existing projects that already had CI/CD enabled are unchanged. Also, this setting only changes
the project default, so project owners [can still enable CI/CD in the project settings](../ci/enable_or_disable_ci.md#enable-cicd-in-a-project).
For installations from source:
1. Open `gitlab.yml` with your editor and set `builds` to `false`:
```yaml
## Default project features settings
default_projects_features:
issues: true
merge_requests: true
wiki: true
snippets: false
builds: false
```
1. Save the `gitlab.yml` file.
1. Restart GitLab:
```shell
sudo service gitlab restart
```
For Omnibus GitLab installations:
1. Edit `/etc/gitlab/gitlab.rb` and add this line:
```ruby
gitlab_rails['gitlab_default_projects_features_builds'] = false
```
1. Save the `/etc/gitlab/gitlab.rb` file.
1. Reconfigure GitLab:
```shell
sudo gitlab-ctl reconfigure
```
## Set the `needs:` job limit **(FREE SELF)**
The maximum number of jobs that can be defined in `needs:` defaults to 50.
A GitLab administrator with [access to the GitLab Rails console](operations/rails_console.md#starting-a-rails-console-session)
can choose a custom limit. For example, to set the limit to `100`:
```ruby
Plan.default.actual_limits.update!(ci_needs_size_limit: 100)
```
To disable directed acyclic graphs (DAG), set the limit to `0`.
<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->
