S3 Static Website from the CLI

Now we will take a look at how to setup an S3 bucket to host a static website, using the aws cli. Skip to the bottom if you just want the script.

The steps for hosting a static website using s3 are pretty much the following:

1. Create a new bucket with a unique name
2. Enable public access to the bucket
3. Update the bucket policy for public read access:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "PublicReadGetObject",
      "Effect": "Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::a-bucket-name/*"
    }
  ]
}

4. Enable the s3 bucket to host an index and error html page
5. Upload your website

We already know how to do this from the web console, but that involves a lot of clicking on buttons and stuff, so here's how to do it using the aws cli.

CLI Commands

aws s3 mb "s3://a-bucket-name" \
--region us-west-2 \
--profile your-profile-name

aws s3 mb will create a new bucket. Make sure you change a-bucket-name to something better.

aws s3api put-public-access-block \
    --bucket a-bucket-name \
    --public-access-block-configuration \
    "BlockPublicAcls=false,IgnorePublicAcls=false,BlockPublicPolicy=false,RestrictPublicBuckets=false" \
    --profile your-profile-name

aws s3api put-public-access-block allows you to configure the public access to the bucket. We're setting all of the blocks to false to enable public access.
