Security Group

The Security Group tab controls the inbound and outbound traffic rules applied to the scale group's nodes. It is available when the group is Running or Scaling. Every node the Scaler launches inherits the security groups attached here.

A scale group must always have at least one security group attached — you cannot detach the last one.

What the Tab Shows​

The tab lists the security groups attached to the scale group and their rules. For each rule you can review the protocol, port range, network type, and source/destination, just as on a node's security group.

Attach a Security Group​

  1. On the Security Group tab, choose a group to attach from the available list.
  2. Confirm the attachment.

The portal applies the group's rules to the running group nodes (this can take a moment to propagate) and to any nodes the Scaler launches afterward.

Detach a Security Group​

  1. On the Security Group tab, select the security group to remove.
  2. Confirm the detachment.

You cannot remove the only attached security group — attach another first if you need to replace it.
