Getting Started

(Optional) Modifying Security Group Rules

• This solution uses port 50000 to communicate with the Jenkins master node. By default, the VPC subnet created in this solution allows access from port 50000. Configure an IP address whitelist by referring to Modifying a Security Group Rule.

A security group is a collection of access control rules for cloud resources, such as cloud servers, containers, and databases, to control inbound and outbound traffic. Cloud resources associated with the same security group have the same security requirements and are mutually trusted within a VPC.

You can modify the security group policy, for example, by adding, modifying, or deleting a TCP port, as follows:

• Adding a security group rule: Add an inbound rule and enable a TCP port if needed.
• Modifying a security group rule: Inappropriate security group settings can be a serious security risk. You can modify security group rules to ensure the network security of your ECSs.
• Deleting a security group rule: If the source or destination IP address of an inbound or outbound security group rule changes, or a port does not need to be enabled, you can delete the security group rule.
