## Configuring a bucket for website access
|
||
|
|
|
||
|
|
There are two methods to expose buckets as website:
|
||
|
|
|
||
|
|
1. using the PutBucketWebsite S3 API call, which is allowed for access keys that have the owner permission bit set
|
||
|
|
|
||
|
|
2. from the Garage CLI, by an adminstrator of the cluster
|
||
|
|
|
||
|
|
The `PutBucketWebsite` API endpoint [is documented](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html) in the official AWS docs.
|
||
|
|
This endpoint can also be called [using `aws s3api`](https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html) on the command line.
|
||
|
|
The website configuration supported by Garage is only a subset of the possibilities on Amazon S3: redirections are not supported, only the index document and error document can be specified.
|
||
|
|
|
||
|
|
If you want to expose your bucket as a website from the CLI, use this simple command:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
garage bucket website --allow my-website
|
||
|
|
```
|
||
|
|
|
||
|
|
Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
|
||
|
|
|
||
|
|
## How exposed websites work
|
||
|
|
|
||
|
|
Our website serving logic is as follow:
|
||
|
|
|
||
|
|
- Supports only static websites (no support for PHP or other languages)
|
||
|
|
- Does not support directory listing
|
||
|
|
- The index file is defined per-bucket and can be specified in the `PutBucketWebsite` call
|
||
|
|
or on the CLI using the `--index-document` parameter (default: `index.html`)
|
||
|
|
- A custom error document for 404 errors can be specified in the `PutBucketWebsite` call
|
||
|
|
or on the CLI using the `--error-document` parameter
|
||
|
|
|
||
|
|
Now we need to infer the URL of your website through your bucket name.
|
||
|
|
Let assume:
|
||
|
|
- we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](@/documentation/reference-manual/configuration.md#root_domain))
|
||
|
|
- our bucket name is `garagehq.deuxfleurs.fr`.
|
||
|
|
|
||
|
|
Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
|
||
|
|
|
||
|
|
- `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
|
||
|
|
|
||
|
|
- `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
|
||
|
|
|
||
|
|
You can try this logic locally, without configuring any DNS, thanks to `curl`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# prepare your test
|
||
|
|
echo hello world > /tmp/index.html
|
||
|
|
mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
|
||
|
|
|
||
|
|
curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
|
||
|
|
# should print "hello world"
|
||
|
|
|
||
|
|
curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
|
||
|
|
# should also print "hello world"
|
||
|
|
```
|
||
|
|
|
||
|
|
Now that you understand how website logic works on Garage, you can:
|
||
|
|
|
||
|
|
- make the website endpoint listens on port 80 (instead of 3902)
|
||
|
|
- use iptables to redirect the port 80 to the port 3902:
|
||
|
|
`iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
|
||
|
|
- or configure a [reverse proxy](@/documentation/cookbook/reverse-proxy.md) in front of Garage to add TLS (HTTPS), CORS support, etc.
|
||
|
|
|
||
|
|
You can also take a look at [Website Integration](@/documentation/connect/websites.md) to see how you can add Garage to your workflow.
