Warning: This is not designed for production use.
This is an example of a consul cluster built in AMS using terraform.
It will start a 3 member cluster that is self discovering, there is no need to configure anything once the servers have been started.
In order to use this you will need an AWS account and appropriate AWS credentials, as detailed in the terraform AWS provider documentation.
Running this project may incur charges.
This can be run out of the box, but you may wish to override some of the variables to avoid conflicts with other infrastructure in you AWS account.
Initialise terraform:
$ terraform init
This project requires an Amazon EC2 key pair.
Specify the key pair name when running terraform, this can be done by creating a terraform.tfvar file in this project
containing the variable name and value:
key_name = "my-key-pair-name"
Now apply the terraform project:
terraform apply
When you're finished playing remember to destroy your infrastructure:
terraform destroy
Use the EC2 console to find the public IP addresses of the servers in your cluster.
You can ssh to any of the consul machines using their public IP, the username 'ubuntu' and the private key for the key pair used above.
ssh -i ./id_rsa [email protected]
Using the consul CLI the members of the cluster can be listed:
$ consul members
Node Address Status Type Build Protocol DC Segment
ip-192-168-1-127 192.168.1.127:8301 alive server 1.0.6 2 terraform-consul <all>
ip-192-168-1-136 192.168.1.136:8301 alive server 1.0.6 2 terraform-consul <all>
ip-192-168-1-144 192.168.1.144:8301 alive server 1.0.6 2 terraform-consul <all>
You can also access the UI using one of the nodes public IP addresses:
