## Plus en détail
Nous hébergeons gratuitement les sites dont l'adresse web ressemble à `monbeausite.deuxfleurs.fr`. Si vous souhaitez votre propre nom de domaine (par exemple `monbeausite.fr`), la location du nom de domaine sera à votre charge (~15-20€/an).
Nous avons de l'expérience en hébergement de sites fonctionnant avec [Wordpress](https://fr.wordpress.org/). C'est un système de gestion de contenu ([CMS](https://fr.wikipedia.org/wiki/Syst%C3%A8me_de_gestion_de_contenu) en anglais) qui permet de construire et d'administrer un site Internet *facilement et sans connaissances préalables*. Si Wordpress ne vous convient pas, on peut trouver ensemble une autre solution adaptée à vos besoins et envies.

Si Wordpress ne vous convient pas, on déterminera ensemble une solution adaptée à vos besoins et envies.
Nous assurons enfin la gestion de **sauvegardes de données** : en hébergeant vos données chez nous, vous avez la certitude de ne pas tout perdre en cas de pépin (tel que le décès prématuré d'un disque dur).

## En conclusion
Venez chez nous ! On vous fera un havre numérique aux petits oignons. Aider Internet à retrouver sa diversité d'antan, c'est important pour nous. On veut voir des blogs en pagaille, des réseaux sociaux délaissés, des thèmes loufoques et la mort de l'uniformisation graphique.
À terme, on demandera (sans doute) de s'inscrire à l'association pour être hébergé, mais pour le moment c'est gratuit et ouvert à tou.te.s, profitez-en !

Store pile of bytes in your garage.
## Quickstart on an existing deployment
First, chances are that your garage deployment is secured by TLS.
All your commands must be prefixed with their certificates.
I will define an alias once and for all to ease future commands.
Please adapt the path of the binary and certificates to your installation!
```
alias grg="/garage/garage --ca-cert /secrets/garage-ca.crt --client-cert /secrets/garage.crt --client-key /secrets/garage.key"
```
Now we can check that everything is going well by checking our cluster status:
```
grg status
```
Don't forget that `help` command and `--help` subcommands can help you anywhere, the CLI tool is self-documented! Two examples:
```
grg help
grg bucket allow --help
```
Fine, now let's create a bucket (we imagine that you want to deploy nextcloud):
```
grg bucket create nextcloud-bucket
```
Check that everything went well:
```
grg bucket list
grg bucket info nextcloud-bucket
```
Now we will generate an API key to access this bucket.
Note that API keys are independent of buckets: one key can access multiple buckets, multiple keys can access one bucket.
Now, let's start by creating a key only for our PHP application:
```
grg key new --name nextcloud-app-key
```
You will have the following output (this one is fake, `key_id` and `secret_key` were generated with the openssl CLI tool):
```
Key { key_id: "GK3515373e4c851ebaad366558", secret_key: "7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34", name: "nextcloud-app-key", name_timestamp: 1603280506694, deleted: false, authorized_buckets: [] }
```
Check that everything works as intended (be careful, info works only with your key identifier and not with its friendly name!):
```
grg key list
grg key info GK3515373e4c851ebaad366558
```
Now that we have a bucket and a key, we need to give permissions to the key on the bucket!
```
grg bucket allow --read --write nextcloud-bucket --key GK3515373e4c851ebaad366558
```
You can check at any times allowed keys on your bucket with:
```
grg bucket info nextcloud-bucket
```
Now, let's move to the S3 API!
We will use the `s3cmd` CLI tool.
You can install it via your favorite package manager.
Otherwise, check [their website](https://s3tools.org/s3cmd)
We will configure `s3cmd` with its interactive configuration tool, be careful not all endpoints are implemented!
Especially, the test run at the end does not work (yet).
```
$ s3cmd --configure
Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.
Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key: GK3515373e4c851ebaad366558
Secret Key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
Default Region [US]: garage
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: garage.deuxfleurs.fr
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: garage.deuxfleurs.fr
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]:
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:
New settings:
Access Key: GK3515373e4c851ebaad366558
Secret Key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
Default Region: garage
S3 Endpoint: garage.deuxfleurs.fr
DNS-style bucket+hostname:port template for accessing a bucket: garage.deuxfleurs.fr
Encryption password:
Path to GPG program: /usr/bin/gpg
Use HTTPS protocol: True
HTTP Proxy server name:
HTTP Proxy server port: 0
Test access with supplied credentials? [Y/n] n
Save settings? [y/N] y
Configuration saved to '/home/quentin/.s3cfg'
```
Now, if everything works, the following commands should work:
```
echo hello world > hello.txt
s3cmd put hello.txt s3://nextcloud-bucket
s3cmd ls s3://nextcloud-bucket
s3cmd rm s3://nextcloud-bucket/hello.txt
```
That's all for now!
## Context
Data storage is critical: it can lead to data loss if done badly and/or on hardware failure.

There was many attempts in research too. I am only thinking to [LBFS](https://pdos.csail.mit.edu/papers/lbfs:sosp01/lbfs.pdf) that was used as a basis for Seafile.

#### Random notes
--> we should not talk about block. It is the abstraction that manipulate your FS to interact with your hard drive. "Chunk" is probably more appropriate. Block storage are a class of distributed storage where you expose the abstraction of your hard drive over the network, mainly SATA over ethernet, thinking to SCSI, FiberChannel, and so on
