This is particularly useful for migrating legacy resources to Terraform. Terraform import is a powerful command that you can use.<\/li>\n<li>This facilitates the quick adoption of Infrastructure as Code by integrating existing infra into your Terraform workflow.<\/li>\n<\/ul>\n<p>Example:<\/p>\n<pre>terraform import aws_s3_bucket.example &lt;bucket-name&gt;<\/pre>\n<h4><span style=\"text-decoration: underline;\"><strong><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-68969 aligncenter\" src=\"https:\/\/www.tothenew.com\/blog\/wp-ttn-blog\/uploads\/2024\/12\/unnamed-5.png\" alt=\"\" width=\"776\" height=\"205\" srcset=\"\/blog\/wp-ttn-blog\/uploads\/2024\/12\/unnamed-5.png 776w, \/blog\/wp-ttn-blog\/uploads\/2024\/12\/unnamed-5-300x79.png 300w, \/blog\/wp-ttn-blog\/uploads\/2024\/12\/unnamed-5-768x203.png 768w, \/blog\/wp-ttn-blog\/uploads\/2024\/12\/unnamed-5-624x165.png 624w\" sizes=\"(max-width: 776px) 100vw, 776px\" \/><br \/>\n<\/strong><\/span><\/h4>\n<h4><strong>Tip 10: Use the sensitive Attribute in Terraform Outputs<\/strong><\/h4>\n<ul>\n<li>When using outputs in Terraform that contain sensitive data (such as <strong>passwords, secret credentials, API keys, or other confidential information<\/strong>), use the sensitive attribute.
