Automation of static website hosting in S3 using boto3

Question

Can configuring a bucket to host a static website be automated, from bucket creation to uploading of files, using just boto3?

I managed to create scripts for these steps:
1. Create a bucket

```python
client = boto3.client('s3')
client.create_bucket(
            Bucket=bucket_name,
            CreateBucketConfiguration={
                'LocationConstraint': self.client.meta.region_name
            },
        )
```

2. Enable static website hosting

```python
client.put_bucket_website(
            Bucket=bucket_name,
            WebsiteConfiguration={
                'ErrorDocument': {'Key': 'error.html'},
                'IndexDocument': {'Suffix': 'index.html'},
            },
        )
```

3. Change permissions and bucket policy

```python
bucket_policy = {
        'Version': '2012-10-17',
        'Statement': [
            {
                'Sid': 'PublicReadGetObject',
                'Effect': 'Allow',
                'Principal': '*',
                'Action': 's3:GetObject',
                'Resource': BUCKET_ARN,
            }
        ],
    }
bucket_policy = json.dumps(bucket_policy)
client.put_bucket_policy(Bucket=bucket_name, Policy=bucket_policy)
```

4. Upload file

```python
    for subdir, dirs, files in os.walk(base_dir):
            for file in files:
                key = file
                if subdir != base_dir:
                    rel_path = os.path.relpath(subdir, base_dir)
                    key = os.path.join(rel_path, file)

full_path = os.path.join(subdir, file)
                mime_type = mimetypes.guess_type(full_path)[0]

if mime_type:
                    with open(full_path, 'rb') as data:
                        self.client.put_object(
                            Bucket=bucket_name,
                            Key=key,
                            Body=data,
                            ContentType=mime_type,
                        )
```

However the website is not hosted properly. For one, when typing the endpoint in the address bar, instead of displaying the page it downloads the content of index.html file. Did I miss any steps here? Are there other things to consider?

Answer

Hi,

You have got an issue with your bucket policy,
```
'Action': 's3:GetObject',
'Resource': f'{BUCKET_ARN}/*'
```
With Action with *Object, you must add **/\*** meaning all objects.

Answer

You're almost there! What you're not doing is setting the content type when uploading the file to S3. The AWS CLI does this for you automatically (and silently) but you need to set it when using boto3. Luckily that's really easy:

```
s3 = boto3.client('s3')

s3.put_object(Bucket='bucketNameHere', Key='index.html', Body=bodyOfFileGoesHere, ContentType='text/html')
```
