Set a security group as default

The default security group is the one a new node in its project and region starts with, unless you pick another group while creating the node. Each project and region has one default at a time, so making a group default takes the role away from the previous one.

Before you begin

• The security group you want as the default. See Create a security group.

Make the group the default

1. Open Network > Security Group.
2. Open the group’s Actions menu and choose Make Group Default.

The Default column now marks this group, and the previous default in the same project and region is an ordinary group again. Nodes that are already running keep the groups they have.

To make a group the default as you create it, turn Make this group default on in the create form.

Every new node in this project and region now starts with this group. A group can be deleted only when it is not the default, so this is also the first step to removing an old default; see Delete a security group.
