If a setting has an invalid value, it's not possible to update any setting until you fix that value. Updating any of these settings, except enabled, does not affect existing workspaces.

`enabled`

Use this setting to define whether:

The GitLab agent can communicate with the GitLab instance.
You can create a workspace with the GitLab agent.

The default value is false.

To enable remote development in the agent configuration, set enabled to true:

remote_development:
  enabled: true

If remote development is disabled, an administrator must manually delete any running workspaces to remove those workspaces from the Kubernetes cluster.

`dns_zone`

Use this setting to define the DNS zone of the URL where workspaces are available.

Example configuration:

remote_development:
  dns_zone: "<workspaces.example.dev>"

`gitlab_workspaces_proxy`

Use this setting to define the namespace where gitlab-workspaces-proxy is installed. The default value for gitlab_workspaces_proxy.namespace is gitlab-workspaces.

Example configuration:

remote_development:
  gitlab_workspaces_proxy:
    namespace: "<custom-gitlab-workspaces-proxy-namespace>"

`network_policy`

Use this setting to define the network policy for each workspace. This setting controls network traffic for workspaces.

The default value is:

remote_development:
  network_policy:
    enabled: true
    egress:
      - allow: "0.0.0.0/0"
        except:
          - "10.0.0.0/8"
          - "172.16.0.0/12"
          - "192.168.0.0/16"

In this configuration:

The network policy is generated for each workspace because enabled is true.
The egress rules allow all traffic to the internet (0.0.0.0/0) except to the IP CIDR ranges 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

The behavior of the network policy depends on the Kubernetes network plugin. For more information, see the Kubernetes documentation.

`network_policy.enabled`

Use this setting to define whether the network policy is generated for each workspace. The default value for network_policy.enabled is true.

`network_policy.egress`

Version history

Introduced in GitLab 16.7.

Use this setting to define a list of IP CIDR ranges to allow as egress destinations from a workspace.

Define egress rules when:

The GitLab instance is on a private IP range.
The workspace must access a cloud resource on a private IP range.

Each element of the list defines an allow attribute with an optional except attribute. allow defines an IP range to allow traffic from. except lists IP ranges to exclude from the allow range.

Example configuration:

remote_development:
  network_policy:
    egress:
      - allow: "0.0.0.0/0"
        except:
          - "10.0.0.0/8"
          - "172.16.0.0/12"
          - "192.168.0.0/16"
      - allow: "172.16.123.1/32"

In this example, traffic from the workspace is allowed if:

The destination IP is any range except 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16.
The destination IP is 172.16.123.1/32.

`default_resources_per_workspace_container`

Version history

Introduced in GitLab 16.8.

Use this setting to define the default requests and limits for CPU and memory per workspace container. Any resources you define in your devfile override this setting.

For default_resources_per_workspace_container, requests and limits are required. For more information about possible CPU and memory values, see Resource units in Kubernetes.

Example configuration:

remote_development:
  default_resources_per_workspace_container:
    requests:
      cpu: "0.5"
      memory: "512Mi"
    limits:
      cpu: "1"
      memory: "1Gi"

`max_resources_per_workspace`

Version history

Introduced in GitLab 16.8.

Use this setting to define the maximum requests and limits for CPU and memory per workspace.

For max_resources_per_workspace, requests and limits are required. For more information about possible CPU and memory values, see:

Workspaces fail when they exceed the values you set for requests and limits.

Example configuration:

remote_development:
  max_resources_per_workspace:
    requests:
      cpu: "1"
      memory: "1Gi"
    limits:
      cpu: "2"
      memory: "2Gi"

The maximum resources you define must include any resources required for init containers to perform bootstrapping operations such as cloning the project repository.

`workspaces_quota`

Version history

Introduced in GitLab 16.9.

Use this setting to set the maximum number of workspaces for the GitLab agent.

You cannot create new workspaces for an agent when:

The number of workspaces for the agent has reached the defined workspaces_quota.
workspaces_quota is set to 0.

If workspaces_quota is set to a value below the number of non-terminated workspaces for an agent, the agent's workspaces are not terminated automatically.

The default value is -1 (unlimited). Possible values are greater than or equal to -1.

Example configuration:

remote_development:
  workspaces_quota: 10

`workspaces_per_user_quota`

Version history

Introduced in GitLab 16.9.

Use this setting to set the maximum number of workspaces per user.

You cannot create new workspaces for a user when:

The number of workspaces for the user has reached the defined workspaces_per_user_quota.
workspaces_per_user_quota is set to 0.

If workspaces_per_user_quota is set to a value below the number of non-terminated workspaces for a user, the user's workspaces are not terminated automatically.

The default value is -1 (unlimited). Possible values are greater than or equal to -1.

Example configuration:

remote_development:
  workspaces_per_user_quota: 3

`use_kubernetes_user_namespaces`

Version history

Introduced in GitLab 17.4.

Use this setting to specify whether to use the user namespaces feature in Kubernetes.

User namespaces isolate the user running inside the container from the user on the host.

The default value is false. Before you set the value to true, ensure your Kubernetes cluster supports user namespaces.

Example configuration:

remote_development:
  use_kubernetes_user_namespaces: true

For more information about use_kubernetes_user_namespaces, see user namespaces.

`default_runtime_class`

Version history

Introduced in GitLab 17.4.

Use this setting to select the container runtime configuration used to run the containers in the workspace.

The default value is "", which denotes the absence of a value.

Example configuration:

remote_development:
  dns_zone: "<workspaces.example.dev>"
```0

A valid value:

- Contains 253 characters or less.
- Contains only lowercase letters, numbers, `-`, or `.`.
- Starts with an alphanumeric character
- Ends with an alphanumeric character.

For more information about `default_runtime_class`, see
[Runtime Class](https://kubernetes.io/docs/concepts/containers/runtime-class/).

## `allow_privilege_escalation`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/13983) in GitLab 17.4.

Use this setting to control whether a process can gain more privileges than its parent process.

This setting directly controls whether the [`no_new_privs`](https://www.kernel.org/doc/Documentation/prctl/no_new_privs.txt)
flag gets set on the container process.

The default value is `false`. The value can be set to `true` only if either:

- [`default_runtime_class`](#default_runtime_class) is set to a non-empty value.
- [`use_kubernetes_user_namespaces`](#use_kubernetes_user_namespaces) is set to `true`.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```1

For more information about `allow_privilege_escalation`, see
[Configure a Security Context for a Pod or Container](https://kubernetes.io/docs/tasks/configure-pod-container/security-context/).

## `image_pull_secrets`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/14664) in GitLab 17.6.

Use this setting to specify existing Kubernetes secrets of the type `kubernetes.io/dockercfg`
or `kubernetes.io/dockerconfigjson` required by workspaces to pull private images.

The default value is `[]`.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```2

In this example, the secret `image-pull-secret-name` from the namespace
`image-pull-secret-namespace` is synced to the namespace of the workspace.

For `image_pull_secrets`, the `name` and `namespace` attributes are required.
The name of the secret must be unique.

If the secret you've specified does not exist in the Kubernetes cluster, the secret is ignored.
When you delete or update the secret, the secret is deleted or updated
in all the namespaces of the workspaces where the secret is referenced.

## `annotations`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/13983) in GitLab 17.4.

Use this setting to attach arbitrary non-identifying metadata to the Kubernetes objects.

The default value is `{}`.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```3

A valid annotation key is a string made of two parts:

- Optional. A prefix. The prefix must be 253 characters or less, and contain period-separated DNS labels. The prefix must end with a slash (`/`).
- A name. The name must be 63 characters or less and contain only alphanumeric characters, dashes (`-`), underscores (`_`), and periods (`.`). The name must begin and end with an alphanumeric character.

You shouldn't use prefixes that end with `kubernetes.io` and `k8s.io` because they are reserved for Kubernetes core components.
Prefixes that end with `gitlab.com` are also reserved.

A valid annotation value is a string.

For more information about `annotations`, see
[Annotations](https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/).

## `labels`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/13983) in GitLab 17.4.

Use this setting to attach arbitrary identifying metadata to the Kubernetes objects.

The default value is `{}`.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```4

A label key is a string made of two parts:

- Optional. A prefix. The prefix must be 253 characters or less, and contain period-separated DNS labels. The prefix must end with a slash (`/`).
- A name. The name must be 63 characters or less and contain only alphanumeric characters, dashes (`-`), underscores (`_`), and periods (`.`). The name must begin and end with an alphanumeric character.

You shouldn't use prefixes that end with `kubernetes.io` and `k8s.io` because they are reserved for Kubernetes core components.
Prefixes that end with `gitlab.com` are also reserved.

A valid label value:

- Contains 63 characters or less. The value can be empty.
- Begins and ends with an alphanumeric character.
- Can contain dashes (`-`), underscores (`_`), and periods (`.`).

For more information about `labels`, see
[Labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/).

## `max_active_hours_before_stop`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/14910) in GitLab 17.6.

Use this setting to automatically stop the agent's workspaces after the specified number of hours
have passed, because the workspace last transitioned to an active state.
An "active state" is defined as any non-stopped or non-terminated state.

The timer for this setting starts when you create the workspace, and is reset every time you
restart the workspace.
It also applies even if the workspace is in an error or failure state.

The default value is `36`, or one and a half days. This avoids stopping the workspace during
the user's typical working hours.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```5

A valid value:

- Is an integer.
- Is greater than or equal to `1`.
- Is less than or equal to `8760` (one year).
- `max_active_hours_before_stop` + `max_stopped_hours_before_termination` must be less than or equal to `8760`.

The automatic stop is only triggered on a full reconciliation, which happens every hour.
This means that the workspace might be active for up to one hour longer than the configured value.

## `max_stopped_hours_before_termination`

### Version history

- [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/14910) in GitLab 17.6.

Use this setting to automatically terminate the agent's workspaces after they have been in the stopped
state for the specified number of hours.

The default value is `722`, or approximately one month.

**Example configuration:**

```yaml
remote_development:
  dns_zone: "<workspaces.example.dev>"
```6

A valid value:

- Is an integer.
- Is greater than or equal to `1`.
- Is less than or equal to `8760` (one year).
- `max_active_hours_before_stop` + `max_stopped_hours_before_termination` must be less than or equal to `8760`.

The automatic termination is only triggered on a full reconciliation, which happens every hour.
This means that the workspace might stop for up to one hour longer than the configured value.
