AWS S3 Host Static Website

I needed to pop a static website into a S3 bucket because its current containerised hosting in AWS Lightsail was proving to be problematic with new deploys (wierd javascript errors) and attracting a higher hosting cost. (EC2 compute to run the container service)

Lucky for me I work with legends who have already figured this out so most of the below is based on the work done by Jaco Brink - cheers brother!

AWS Config

The below assumes your AWS CLI is installed and configured.

Note the user will need permissions policies AmazonS3FullAccess and AWSCloudFormationFullAccess. Hopefully you add these via a user group and not attach directly like a moegoe 😐

Create the Bucket

Cloud formation is the weapon of choice when deploying infrastructure. Its repeatable and then managed by AWS.

The cloud formation template data here is kept in porky-bucket-website.json because YML hurts my brain.

                                },
                                {
                                    "Fn::Sub": "arn:aws:s3:::${MyS3Bucket}/*"
                                }
                            ],
                            "Principal": {
                                "AWS": [
                                    "*"
                                ]
                            }
                        }
                    ]
                }
            }
        }
    }
}

Now run the cloudformation comand:

1
aws cloudformation create-stack --stack-name PorkyBucketWebsiteStack --template-body file://./aws-deploy/porky-bucket-website.json --profile infrauser --region ap-southeast-2

You can also run with update-stack to update.

Deploy website

Now after publishing your code to ./pub deploy it to the bucket.

1
aws s3 sync './pub' 's3://ums-audits' --acl public-read --profile infrauser --region ap-southeast-2

The DNS is avalible from the AWS Console -> Amazon S3 -> Buckets/porky-bucket-website -> Properties -> Static website hosting

By default this will not have HTTPS.
