This repository contains IAC code to setup chainlink nodes and relevant resources in GCP
See the github-module for the source terraform repository from where the module is inherited.
Check Terraform registry chainlinknode for Provision Instructions.
Clone this git repo Add service_account.json file in your root folder with your cloud provider and project details. For help check this
Install terraform
- Select what node_type ( FM / OCR / Keeper ), you want to add
- Duplicate any of the given folders inside it. ( e.g.bsc / eth )
- Edit main.tf file.
- Make sure you have the latest version of the registry.
- Go to state.tf file. Edit prefix = "cl/<node_name>-<node_type>.tfstate". This will store the state in GCP
- Again in terraform.tfvars file , edit these two values ( you can configure other values as wqell if required )
node_name = <node_name>
node_type = <node-type>Create a bash file in this format "<node_name>-<node_type>-startup.sh". Add your application code here. For reference check files here. Upload the file in the above bucket.Check the gsutil URI. It will read something like this : gs://myc-node/cl/cl-metadata-script/xdai-fm-startup.sh
- Keep outputs.tf , provider.tf , variables.tf files as is.
- Thats it!
Initialise your terraform in the respective folder.
terraform initRun to check the execution flow.
terraform planOnce satisfied , apply to start the execution
terraform apply --auto-approve- Run to check what all resources will be destroyed.
terraform destroy - Once happy you can enter yes and the node with its associated resources will be deleted
