Deploy isolated workloads across multiple locations and zones

The scripts in this directory can be used to deploy or clean up the resources for the IBM Cloud solution tutorial.

File	Description
vpc-multi-region-single-create.sh	Creates VPC resources in a single region.
vpc-multi-region-create.sh	Creates VPC resources in multiple regions.
vpc-multi-region-cleanup.sh	Removes all created resources.
cis/cis-glb-create.sh	Configures a global load balancer.

Instructions

In a browser visit IAM authorizations and add an authorization from the source: VPC Infrastructure, Load Balancer for VPC to the Target Certificate Manager
Open the terminal and add your SSH key
```
ssh-add -K ~./ssh/<YOUR_PRIVATE_KEY>
```
Navigate to vpc-multi-region folder in the repo and create a .env file from the template
```
 cd vpc-multi-region
 cp template.env .env
```
Provide the required details in the .env file and save.
Execute the shell script and follow the steps of execution to setup VPCs in multiple regions in ONE-GO
```
./vpc-multi-region-create.sh
```

For creating VPC resources in a single region, run this script

./vpc-multi-region-single-create <REGION_NAME>

The following named resources are created by the script above:

Resource type	Name(s)	Comments
Virtual Private Cloud (VPC)	BASENAME-REGION
Subnet	BASENAME-bastion-REGION-ZONE1
Subnet	BASENAME-REGION-ZONE1-subnet
Subnet	BASENAME-REGION-ZONE2-subnet
Security Group	BASENAME-bastion-REGION-ZONE1-sg
Security Group	BASENAME-maintenance-sg
Security Group	BASENAME-sg
Virtual Server Instance (VSI)	BASENAME-bastion-REGION-ZONE1-vsi
Virtual Server Instance (VSI)	BASENAME-REGION-zone1-vsi
Virtual Server Instance (VSI)	BASENAME-REGION-zone2-vsi
Floating IP	BASENAME-bastion-ip
Floating IP	BASENAME-REGION-zone1-ip
Floating IP	BASENAME-REGION-zone2-ip
Load Balancer	BASENAME-REGION-lb
Load Balancer back-end pool	BASENAME-REGION-lb-pool	Instances are attached as `pool members` to the pool with HTTP and HTTPS front-end listeners

The Global Load Balancer will be connected to the VPC Load balancers when using the vpc-multi-region-create.sh. If executing manually run the below script to create a Global Load Balancer(GLB)
```
cd cis
./cis-glb-create.sh
```

Run the below script to delete CIS GLB resources and VPC resources in ONE-GO.
```
./vpc-multi-region-cleanup.sh <VPC_NAME> <LOAD_BALANCER_NAME>
```

To delete VPC resources,

cd ../scripts && ./vpc-cleanup.sh <VPC_NAME>

To delete CIS global load balancer resources,
```
cd cis && ./cis-glb-cleanup.sh
```
