This template example supports adding all created ECS to a single/multiple (up to three) SLB s as multiple back-end servers
Sketch:
ECS instances in the template support specifying different instance names and host names, and can choose network type as VPC or CLASSIC. When choosing not to create VPC, ECS instance specifications need to be changed. The reason is that ECS instance specifications can be created, which are different from those of VPC network types. The default is to create a new SLB instance. If the ID of the SLB instance is passed in, the number of SLB instances needs to be changed. The reason is that the number of SLB instances added to the back-end server needs to be identical according to the number of SLBs in the template and the ID of the SLB (e.g., with the ID of the two SLBs that have been created as parameters, the number of SLBs should be changed to 2).
This template currently supports attaching back-end servers to up to three SLB instances.
Involving resources:
ALIYUN::ECS::VPC (Virtual Private Network)
ALIYUN::ECS::VSwitch (Virtual Switch)
ALIYUN:: ECS:: Security Group
ALIYUN:: ECS:: Instance Group (Cloud Server Group)
ALIYUN:: SLB:: Load Balancer (Load Balancer)
ALIYUN:: SLB:: Backend Server Attachment (adding back-end servers for load balancing)
1. Create ECS Instance Group
The following is an example of creating an ECS Instance code of VPC type, in which batch ECS creation specifies different instance names and host names.
e.g. HostName[1,4]Test HostName: is the prefix of the ECS Instance Group host naming rules; [1,4]:1 is the starting number and 4 is the number of digits. Test: The suffix for naming rules; Results The hostnames of the ECS created were HostName 0001, HostName 002, HostName 0003, and...

2. Adding back-end servers for SLB instances
The following example code creates additional back-end server functions, some ROS function functions used, and some logic judgments defined by itself, which can be consulted according to the schema template.
Considering the need to add back-end servers for multiple SLB instances, the scheme uses Conditions and functions to add back-end servers for single/multiple SLBs.
{ "Type": "ALIYUN::SLB::BackendServerAttachment", "Condition": "IsAttachment1", "Properties": { "LoadBalancerId": { "Fn::If": [ "IsCreateSlb", { "Fn::GetAtt": [ "LoadBalancer", "LoadBalancerId" ] }, { "Fn::Select": [ "0", { "Fn::Split": [ ",", { "Ref": "LoadBalancerIds" } ] } ] } ] }, "BackendServerList": { "Fn::If": [ "IsCreateVpc", { "Fn::GetAtt": [ "EcsInstanceGroupWithVpc", "InstanceIds" ] }, { "Fn::GetAtt": [ "EcsInstanceGroupNoVpc", "InstanceIds" ] } ] }, "BackendServerWeightList": { "Fn::Split": [ ",", { "Ref": "BackendServerWeightList" } ] } } }
3. Conditional Code Example
Please combine Paramters in the template.
