|
||||
|
||||
We propose the following quickstart to setup a full dev. environment as quickly as possible:
|
||||
|
||||
1. Setup a rust/cargo environment and install s3cmd. eg. `dnf install rust cargo s3cmd`
|
||||
2. Run `cargo build` to build the project
|
||||
3. Run `./script/dev-cluster.sh` to launch a test cluster (feel free to read the script)
|
||||
4. Run `./script/dev-configure.sh` to configure your test cluster with default values (same datacenter, 100 tokens)
|
||||
5. Run `./script/dev-bucket.sh` to create a bucket named `éprouvette` and an API key that will be stored in `/tmp/garage.s3`
|
||||
6. Run `source ./script/dev-env.sh` to configure your CLI environment
|
||||
7. You can use `garage` to manage the cluster. Try `garage --help`.
|
||||
8. You can use `s3grg` to add, remove, and delete files. Try `s3grg --help`, `s3grg put /proc/cpuinfo s3://éprouvette/cpuinfo.txt`, `s3grg ls s3://éprouvette`. `s3grg` is a wrapper on `s3cmd` configured with the previously generated API key (the one in `/tmp/garage.s3`).
|
||||
1. Setup a rust/cargo environment. eg. `dnf install rust cargo`
|
||||
2. Install awscli v2 by following the guide [here](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html).
|
||||
3. Run `cargo build` to build the project
|
||||
4. Run `./script/dev-cluster.sh` to launch a test cluster (feel free to read the script)
|
||||
5. Run `./script/dev-configure.sh` to configure your test cluster with default values (same datacenter, 100 tokens)
|
||||
6. Run `./script/dev-bucket.sh` to create a bucket named `eprouvette` and an API key that will be stored in `/tmp/garage.s3`
|
||||
7. Run `source ./script/dev-env-aws.sh` to configure your CLI environment
|
||||
8. You can use `garage` to manage the cluster. Try `garage --help`.
|
||||
9. You can use the `awsgrg` alias to add, remove, and delete files. Try `awsgrg help`, `awsgrg cp /proc/cpuinfo s3://eprouvette/cpuinfo.txt`, or `awsgrg ls s3://eprouvette`. `awsgrg` is a wrapper on the `aws s3` command pre-configured with the previously generated API key (the one in `/tmp/garage.s3`) and localhost as the endpoint.
|
||||
|
||||
Now you should be ready to start hacking on garage!
|
||||
|
||||
## S3 compatibility
|
||||
|
||||
Only a subset of S3 is supported: adding, listing, getting and deleting files in a bucket.
|
||||
Bucket management, ACL and other advanced features are not (yet?) handled through the S3 API but through the `garage` CLI.
|
||||
We primarily test `garage` against the `awscli` tool and `nextcloud`.
|
||||
|
||||
## Setting up Garage
|
||||
|
||||
Use the `genkeys.sh` script to generate TLS keys for encrypting communications between Garage nodes.

|

Garage utilise un modèle de cohérence relativement faible :
|
||||
\vspace{1em}
|
||||
|
||||
\begin{itemize}
|
||||
\item Objets répliqués 3 fois, quorum de 2 pour les lectures et les écritures\\
|
||||
$\to$ cohérence \textbf{``read your writes''}
|
||||
\vspace{1em}
|
||||
\item<2-> Types de donnée CRDT + mécanisme d'anti-entropie\\
|
||||
$\to$ cohérence \textbf{à terme} (eventual consistency)
|
||||
\vspace{1em}
|
||||
\item<3-> Cela s'applique pour chaque fichier individuellement :\\
|
||||
pas de linéarisabilté ou de cohérence causale entre les opérations\\
|
||||
sur des fichiers différents
|
||||
\vspace{1em}
|
||||
\item<4-> \textbf{Avantage :} convient bien à un déploiement géodistribué (multi-datacenter)
