The case includes setup three VPCs on Huawei Cloud and creating ECS and RDS instances in them, and then establishing vpc-peering connections.
- Create key pair file required for ssh connection to ECS instances.
. ./external/ssh-key-generator.sh
- Add the environment variables created with the ssh-key-generator.sh to the tfvars file.
echo "key_name=\"${fname}\"" >> terraform.auto.tfvars
echo "public_key=\"$(cat ${fpath}.pub)\"" >> terraform.auto.tfvars
- Terraform commands that create VPCs, security group, ECS, and RDS instances, respectively.
terraform init
terraform plan
terraform apply -target=module.vpc
terraform apply -target=huaweicloud_networking_secgroup.secgroup
terraform apply -target=huaweicloud_networking_secgroup_rule.rule
terraform apply -target=module.ecs
terraform apply -target=module.rds
- Reach out to the below terraform output values and ping the instances each other.
terraform output ecs_public_ips
terraform output rds_public_ips
terraform output keypair
ssh -i <path/to/your-keypair-file> root@<one-ipaddr-from-ecs_public_ips>
ping <another-ipaddr-from-ecs_public_ips>
ping <another-ipaddr-from-rds_public_ips>
- Establish vpc-peering connections between VPCs. Reach out to the below terraform output values and ping the instances each other with private ip addresses.
terraform apply -target=module.peering -auto-approve
terraform output peering_names
terraform output ecs_private_ips
terraform output rds_private_ips
ssh -i <path/to/your-keypair-file> root@<one-ipaddr-from-ecs_private_ips>
ping <another-ipaddr-from-ecs_private_ips>
ping <another-ipaddr-from-rds_private_ips>
