Last week I wrote a post about creating an S3 Bucket to host a static website. After I posted it I began to wonder, could we command line this to make it creating a bucket a quicker task? This post assumes you have the CLI installed and know the very basics on how to use it. Here is the rundown of the logic and what steps need to take place:

1. A bucket needs to be created, region selected
2. Public access needs to be enabled so people can access the html files
3. Configure it for static website hosting
4. Set the permissions
5. Upload your file and test!

Here is the quick and dirty of what I did, we will clean this up after. Any instance of “tutorial-002-sj” would need to be changed to your bucket name.

// Create the bucket
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/create-bucket.html
aws s3api create-bucket --bucket tutorial-002-sj --region eu-west-1 --create-bucket-configuration LocationConstraint=eu-west-1

// Set the Configuration Options
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-public-access-block.html
aws s3api put-public-access-block --bucket tutorial-002-sj --public-access-block-configuration BlockPublicAcls=false,IgnorePublicAcls=false,BlockPublicPolicy=false,RestrictPublicBuckets=false

// Configure for Static Website Hosting
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html
// Idea for temp file from: https://stuff-things.net/2017/05/03/creating-an-s3-website-redirect-from-the-cli/
printf '{"IndexDocument": {"Suffix": "index.html"},"ErrorDocument": {"Key": "error.html"}}' $2 > website.json
aws s3api put-bucket-website --bucket tutorial-002-sj --website-configuration file://website.json

// Configure Permissions
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-policy.html
printf '{"Version": "2012-10-17","Statement": [{"Sid": "PublicReadForGetBucketObjects","Effect": "Allow","Principal": "*","Action": ["s3:GetObject"],"Resource": ["arn:aws:s3:::tutorial-002-sj/*"]}]}' $2 > policy.json
aws s3api put-bucket-policy --bucket tutorial-002-sj --policy file://policy.json

Now for the better version, this one is a shell script you can run. it is as simple as ./creates3websitebucket.sh <bucketname> it does the rest for you.

#!/bin/bash
BUCKET_NAME=$1

if [ -z "$BUCKET_NAME" ]
then 
	echo -e "\e[31mOops! You cannot leave the bucket name empty... this isnt going to work \n"
	echo -e "\e[39m"
	exit 0
else
	echo -e "\e[32mGreen Good... you gave your bucket a name! \n"
fi

// Create the bucket
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/create-bucket.html
aws s3api create-bucket --bucket $BUCKET_NAME --region eu-west-1 --create-bucket-configuration LocationConstraint=eu-west-1
echo -e "\e[32mBucket Created\n"

// Set the Configuration Options
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-public-access-block.html
aws s3api put-public-access-block --bucket $BUCKET_NAME --public-access-block-configuration BlockPublicAcls=false,IgnorePublicAcls=false,BlockPublicPolicy=false,RestrictPublicBuckets=false
echo -e "\e[32mConfiguration Options Set\n"

// Configure for Static Website Hosting
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html
// Idea for temp file from: https://stuff-things.net/2017/05/03/creating-an-s3-website-redirect-from-the-cli/
printf '{"IndexDocument": {"Suffix": "index.html"},"ErrorDocument": {"Key": "error.html"}}' $2 > website.json
aws s3api put-bucket-website --bucket $BUCKET_NAME --website-configuration file://website.json
echo -e "\e[32mStatic Hosting Options Set\n"
// Cleanup 
rm -rf website.json
echo -e "\e[32mCleaned up website.json temp file\n"

// Configure Permissions
// Reference: https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-policy.html
printf '{"Version": "2012-10-17","Statement": [{"Sid": "PublicReadForGetBucketObjects","Effect": "Allow","Principal": "*","Action": ["s3:GetObject"],"Resource": ["arn:aws:s3:::'"$BUCKET_NAME"'/*"]}]}' $2 > policy.json
aws s3api put-bucket-policy --bucket $BUCKET_NAME --policy file://policy.json
echo -e "\e[32mPermissions Set\n"
rm -rf policy.json
echo -e "\e[32mCleaned up policy.json temp file\n"
echo -e "\e[32mProceed to upload a file and test access!\n\n"
echo -e "\e[39m"
