Requirements

Building The Provider

Clone repository to: $GOPATH/src/github.com/linkpoolio/terraform-provider-chainlink

$ mkdir -p $GOPATH/src/github.com/linkpoolio; cd $GOPATH/src/github.com/linkpoolio
$ git clone git@github.com:linkpoolio/terraform-provider-chainlink

Enter the provider directory and build the provider

$ cd $GOPATH/src/github.com/linkpoolio/terraform-provider-chainlink
$ go build -o terraform-provider-chainlink_v0.2

Using the provider

You can configure the provider with the following:

provider "chainlink" {
    email    = "admin@node.local"
    password = "twochains"
    url      = "http://localhost:6688"
}

All the variables defined above are the defaults. Keep in-mind that if you write the password in clear text within your HCL files, or fetch it via other methods, it will be stored in plain-text or in-state.

Available resources:

  • chainlink_bridge
  • chainlink_spec

Available data sources:

  • chainlink_wallet

chainlink_bridge

This will create and manage bridge types (external adaptors) on the Chainlink node, an example:

resource "chainlink_bridge" "asset_price" {
    name       = "assetprice"
    url        = "http://localhost:8080/price"
}

chainlink_spec

This will create and manage bridge types (external adaptors) on the Chainlink node, an example:

resource "chainlink_spec" "httpget_uint256" {
    json = <<-EOF
{
  "initiators": [
    {
      "type": "runlog"
    }
  ],
  "tasks": [
    {
      "type": "httpget"
    },
    {
      "type": "jsonparse"
    },
    {
      "type": "multiply"
    },
    {
      "type": "ethuint256"
    },
    {
      "type": "ethtx"
    }
  ]
} 
EOF
}

chainlink_wallet

data "chainlink_wallet" "this" {}

output "wallet_address" {
    value = "${data.chainlink_wallet.this.address}"
}
