Task

This task is to implement the back-end changes needed to set the new "update all hosts" setting on macos_updates, and to check for this setting when determining whether to update a device's OS during setup.

• Create the new config in

  fleet/server/fleet/app.go

  Lines 322 to 328 in 25d9420

  	type AppleOSUpdateSettings struct {
  	// MinimumVersion is the required minimum operating system version.
  	MinimumVersion optjson.String `json:"minimum_version"`
  	// Deadline the required installation date for Nudge to enforce the required
  	// operating system version.
  	Deadline optjson.String `json:"deadline"`
  	}

• Add the new logic in needsOSUpdateForDEPEnrollment() to check the setting. If we only want to check this for macOS right now, be sure to add a platform check as well.
• I think GitOps should pick this up automatically, since we just push up the whole JSON...
• ...but we'll need to update generate-gitops (tests for sure, maybe logic too)

Condition of satisfaction

The new macos_updates.update_new_hosts setting should be...

• settable via the PATCH /fleet/config endpoint (for no team)
• returned from the GET /fleet/config endpoint (for no team)
• settable via the PATCH /fleet/teams/:id endpoint (for a team)
• returned from the GET /fleet/teams/:id endpoint (for no team)
• settable via GitOps for "no team"
• settable via GitOps for a team
• output by fleetctl generate-gitops in default.yml
• output by fleetctl generate-gitops in teams/<team-name>.yml

When update_new_hosts is changed for a team:

• a new enabled_macos_update_new_hosts activity will be generated if the setting is true
• a new disabled_macos_update_new_hosts activity will be generated if the setting is false
