Learn more about the process: https://handbook.gitlab.com/handbook/product/product-management/#customer-feature-requests. The section "Release notes" can be used as a summary of the feature and is also required if you want to have your release post blog MR auto generated using the release post item generator: https://about.gitlab.com/handbook/marketing/blog/release-posts/#release-post-item-generator. The remaining sections are the backbone for every feature in GitLab. The goal of this template is brevity for quick/smaller iterations. For a more thorough list of considerations for larger features or feature sets, you can leverage the detailed [feature proposal](https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md).--> ### Release notes <!--What is the problem and solution you're proposing? This content sets the overall vision for the feature and serves as the release notes that will populate in various places, including the [release post blog](https://about.gitlab.com/releases/categories/releases/) and [Gitlab project releases](https://gitlab.com/gitlab-org/gitlab/-/releases). "--> ### Problem to solve Currently, there it not a way to enforce labels/attributes to specific workspace nodes via the K8s Node Selector. This is needed in order to charge-back the use of resources to specific projects or groups. ### Proposal Mechanism to assign labels to the correct workspace node when creating workspaces via the K8s Node Selector [this section expanded](https://docs.gitlab.com/user/workspace/set_up_gitlab_agent_and_proxies/#configure-the-gitlab-agent-for-workspaces) to support adding specific groups or projects. It should also enforce a namespace or other attribute such as a label or annotation for all members of the allowed project ``` Remote_development: enabled: true dns_zone: "<workspaces.example.dev>" # DNS zone of the URL where workspaces are available ``` ### Intended users <!--Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later.
