Setup your CloudAMQP cluster from Terraform
Golang, make, Terraform
-
Install golang: https://golang.org/dl/ Example with default paths
- Download latest version and extract to
/usr/local/go
- Set environmental variable
export GOROOT=/usr/local/go
- Set environmental variable
export GOPATH=$HOME/go
- Set environmental variable
export PATH=$GOROOT/bin:$GOPATH:$GOPATH/bin:$PATH
- Activate module mode
export GO111MODULE=on
(Very important!)
- Download latest version and extract to
-
Install make
sudo apt install make
-
Install terraform: https://learn.hashicorp.com/terraform/getting-started/install.html
- Download the latest version and extract to /usr/local/terraform
- Set environmental variable
export PATH=/usr/local/terraform:$PATH
-
Create a CloudAMQP account if you haven't already:
- Go to https://www.cloudamqp.com/
- Click "Sign Up"
- Sign in
- Go to API access (https://customer.cloudamqp.com/apikeys) and create a key. (note that this is the API key for one of the two APIs CloudAMQP supports.)
The two APIs supported can be found at https://docs.cloudamqp.com (called customer) and https://docs.cloudamqp.com/cloudamqp_api.html (called api). The API key created gain access to the customer API (used to handle the instance). While the second API handles different resources on the instace (such as alarms, notification etc.). The customer API also has a proxy service, which makes it possible for the provider to access the second API through customer API using the same created API key.
Clone repository to $GOPATH/src/github.com/cloudamqp/terraform-provider-cloudamqp
Change directory and build the provider from make. This will call go intall
and install the plugin under $GOPATH/bin
.
$ cd $GOPATH/src/github.com/cloudamqp/terraform-provider-cloudamqp
$ make build
Run terraform init
from the same folder as the tf.file is located. Terraform should also search in $GOPATH/bin
. If this not the case, the provider needs to be manually installed by moving it to $HOME/.terraform.d/plugins
. Install plugins. If $HOME/.terraform.d/plugins
don't exists, the directory needs to be created.
$ mkdir -p ~/.terraform.d/plugins
$ cp $GOPATH/bin/terraform-provider-cloudamqp $HOME/.terraform.d/plugins/terraform-provider-cloudamqp
$ cd <path_to_tf_file>
$ terraform init
More detailed documentation of the provider can be found at: https://docs.cloudamqp.com/cloudamqp_terraform.html
(See the examples.tf file in the repo. It has a bunny VPC example and a simple lemur example.)
cd $GOPATH/src/github.com/cloudamqp/terraform-provider-cloudamqp #This is the root of the repo where examples.tf lives.
terraform plan
When prompted paste in your CloudAMQP API key (created above).
This will give you output on stdout that tells you what would have been created:
- rmq_lemur
Next run
terraform apply
Again, paste in your API key. This should create an actual CloudAMQP instance.
If more information needed, it's possible to increase Terraform log level. Using DEBUG will enable both CloudAMQP and underlying go-api debug logging.
To enable Terraform debug logging.
export TF_LOG=DEBUG

IMPORTANT - PLAN CHANGES BETWEEN SHARED AND DEDICATED
It’s possible to change between shared and dedicated plans (or vice versa). This will however force a destruction of the old instance, before creating a new one. All data will be lost and a new hostname will be created with corresponding DNS record.
Import existing infrastructure into state and bring the resource under Terraform management. Information about the resource will be added to the terraform.state file. Then add manually the given information to the .tf file. Once this is done, run terraform plan to see that the resource is under Terraform management. From here it's possible to add more resources such as alarm.
Import cloudamqp instance and bring it under Terraform management. First declare an empty instance resource in the .tf file. Followed by running the terraform import command
resource "cloudamqp_instance"."rmq_url" {}
Generic form of terraform import command
terraform import {resource_type}.{resource_name} {resource_id}
Example of terraform import command (with resource_id=80)
terraform import cloudamqp_instance.rmq_url 80
All resources depending on the instance resource also needs the instance id when using terraform import, in order to make correct API calls. Resource id and instance id is seperated with ",".
Resource affected by this is:
- cloudamqp_notification
- cloudamqp_alarm
First declare two empty notification and alarm resources in the .tf file. Followed by running the terraform import command.
resource "cloudamqp_notification"."recipient_01" {}
resource "cloudamqp_alarm"."alarm_01" {}
Generic form of terraform import command
terraform import {resource_type}.{resource_name} {resource_id},{instance_id}
You can find {instance_id}
through the API
Example of terraform import command (with instance_id=80)
terraform import cloudamqp_notification.recipient_01 10,80
terraform import cloudamqp_alarm.alarm_01 65,80
Support for setting up VPC peering connection between AWS instance and CloudAMQP. Requires that the AWS instance is used as the requester and CloudAMQP used as an accepter. More detailed description can be found here: setup
