Deploying to S3/Cloudfront
This guide walks through how to host and publish your next Gatsby site to AWS using S3. Optionally - but very recommended - you can add CloudFront, a global CDN to make your site even faster.
Create an IAM account with administration permissions and create an access id and secret for it. You’ll need these in the next step.
Install the AWS CLI and configure it (ensure Python is installed before running these commands):
The AWS CLI will now prompt you for the key and secret, so add them.
Now that your Gatsby site is up and running and AWS access is sorted out, you’ll need to add hosting and make the site live on AWS.
First, install the Gatsby S3 plugin:
Add it to your
gatsby-config.js: (don’t forget to change the bucket name)
And finally, add the deployment script to your
npm run build && npm run deploy to do a build and have it immediately deployed to S3!
Some deployments require passing environment variables. To deploy with environment variables, update the deployment script to your
This command requires
dotenv first, runs build next, and finally deploys to s3.
dotenv, a dependency of Gatsby that doesn’t need to be installed directly, loads environment variables and makes them available globally.
If you have multiple AWS profiles in your machine, you can deploy by declaring your
AWS_PROFILE before the deploy script:
CloudFront is a global CDN and can be used to make your blazing fast Gatsby site load even faster, particularly for first-time visitors. Additionally, CloudFront provides the easiest way to give your S3 bucket a custom domain name and HTTPS support.
There are a couple of things that you need to consider when using gatsby-plugin-s3 to deploy a site which uses CloudFront.
gatsby-plugin-meta-redirect can compensate for the former. But just because you can’t see these issues, doesn’t mean they won’t affect search engines.
In order for all the features of your site to work correctly, you must instead use your S3 bucket’s Static Website Hosting Endpoint as the CloudFront origin. This does (sadly) mean that your bucket will have to be configured for public-read, because when CloudFront is using an S3 Static Website Hosting Endpoint address as the Origin, it’s incapable of authenticating via IAM.
In the gatsby-plugin-s3 configuration file, there are a couple of optional parameters that you can usually leave blank,
hostname. But when you’re using CloudFront, these parameters are vital for ensuring redirects work correctly. If you omit these parameters, redirects will be performed relative to your S3 Static Website Hosting Endpoint. This means if a user visits your site via the CloudFront URL and hits a redirect, they will be redirected to your S3 Static Website Hosting Endpoint instead. This will disable HTTPS and (more importantly) will display an ugly and unprofessional URL in the user’s address bar.
By specifying the
hostname parameters, you can cause redirects to be applied relative to a domain of your choosing.
If you use your site’s URL elsewhere in gatsby-config.js, you can define the URL once at the top of the config:
And then in the Gatsby config you can reference it like so:
If you need the full address elsewhere in your config, you can access it via
