Generates Terraform Import Commands for v4 AWS S3 Bucket Configuration Changes

importS3Resources.js

const fs = require("fs");

const rawData = fs.readFileSync("plan.json");

const data = JSON.parse(rawData);

const changes = data.resource_changes.filter(
  (c) =>
    c.change.actions.indexOf("create") !== -1 &&
    c.type.startsWith("aws_s3_bucket_")
);

const lines = changes.map((c) => {
  let base = `terraform import ${c.address} ${c.change.after.bucket}`;

  if (c.type === "aws_s3_bucket_acl") {
    base = `${base},${c.change.after.acl}`;
  }

  return base;
});

console.log(lines.join("\n"));

Variation for moving Route53 zone to a different account:

const fs = require("fs");

const rawData = fs.readFileSync("plan.json");

const data = JSON.parse(rawData);

const changes = data.resource_changes.filter(
  (c) =>
    c.change.actions.indexOf("create") !== -1 && c.type === "aws_route53_record"
);

const lines = changes.map((c) => {
  const { zone_id, name, type } = c.change.after;
  let base = `terraform import ${c.address} ${zone_id}_${name}_${type}`;
  return base;
});

console.log(lines.join("\n"));
