### Top-level configuration options
|
|
|
|
#### `replication_mode` {#replication_mode}
|
|
|
|
Garage supports the following replication modes:
|
|
|
|
- `none` or `1`: data stored on Garage is stored on a single node. There is no
|
|
redundancy, and data will be unavailable as soon as one node fails or its
|
|
network is disconnected. Do not use this for anything else than test
|
|
deployments.
|
|
|
|
- `2`: data stored on Garage will be stored on two different nodes, if possible
|
|
in different zones. Garage tolerates one node failure, or several nodes
|
|
failing but all in a single zone (in a deployment with at least two zones),
|
|
before losing data. Data remains available in read-only mode when one node is
|
|
down, but write operations will fail.
|
|
|
|
- `2-dangerous`: a variant of mode `2`, where written objects are written to
|
|
the second replica asynchronously. This means that Garage will return `200
|
|
OK` to a PutObject request before the second copy is fully written (or even
|
|
before it even starts being written). This means that data can more easily
|
|
be lost if the node crashes before a second copy can be completed. This
|
|
also means that written objects might not be visible immediately in read
|
|
operations. In other words, this mode severely breaks the consistency and
|
|
durability guarantees of standard Garage cluster operation. Benefits of
|
|
this mode: you can still write to your cluster when one node is
|
|
unavailable.
|
|
|
|
- `3`: data stored on Garage will be stored on three different nodes, if
|
|
possible each in a different zones. Garage tolerates two node failure, or
|
|
several node failures but in no more than two zones (in a deployment with at
|
|
least three zones), before losing data. As long as only a single node fails,
|
|
or node failures are only in a single zone, reading and writing data to
|
|
Garage can continue normally.
|
|
|
|
- `3-degraded`: a variant of replication mode `3`, that lowers the read
|
|
quorum to `1`, to allow you to read data from your cluster when several
|
|
nodes (or nodes in several zones) are unavailable. In this mode, Garage
|
|
does not provide read-after-write consistency anymore. The write quorum is
|
|
still 2, ensuring that data successfully written to Garage is stored on at
|
|
least two nodes.
|
|
|
|
- `3-dangerous`: a variant of replication mode `3` that lowers both the read
|
|
and write quorums to `1`, to allow you to both read and write to your
|
|
cluster when several nodes (or nodes in several zones) are unavailable. It
|
|
is the least consistent mode of operation proposed by Garage, and also one
|
|
that should probably never be used.
|
|
|
|
Note that in modes `2` and `3`,
|
|
if at least the same number of zones are available, an arbitrary number of failures in
|
|
any given zone is tolerated as copies of data will be spread over several zones.
|
|
|
|
**Make sure `replication_mode` is the same in the configuration files of all nodes.
|
|
Never run a Garage cluster where that is not the case.**
|
|
|
|
The quorums associated with each replication mode are described below:
|
|
|
|
| `replication_mode` | Number of replicas | Write quorum | Read quorum | Read-after-write consistency? |
|
|
| ------------------ | ------------------ | ------------ | ----------- | ----------------------------- |
|
|
| `none` or `1` | 1 | 1 | 1 | yes |
|
|
| `2` | 2 | 2 | 1 | yes |
|
|
| `2-dangerous` | 2 | 1 | 1 | NO |
|
|
| `3` | 3 | 2 | 2 | yes |
|
|
| `3-degraded` | 3 | 2 | 1 | NO |
|
|
| `3-dangerous` | 3 | 1 | 1 | NO |
|
|
|
|
Changing the `replication_mode` between modes with the same number of replicas
|
|
(e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
|
|
just changing the `replication_mode` parameter in your config files and restarting all your
|
|
Garage nodes.
|
|
|
|
It is also technically possible to change the replication mode to a mode with a
|
|
different numbers of replicas, although it's a dangerous operation that is not
|
|
officially supported. This requires you to delete the existing cluster layout
|
|
and create a new layout from scratch, meaning that a full rebalancing of your
|
|
cluster's data will be needed. To do it, shut down your cluster entirely,
|
|
delete the `custer_layout` files in the meta directories of all your nodes,
|
|
update all your configuration files with the new `replication_mode` parameter,
|
|
restart your cluster, and then create a new layout with all the nodes you want
|
|
to keep. Rebalancing data will take some time, and data might temporarily
|
|
appear unavailable to your users. It is recommended to shut down public access
|
|
to the cluster while rebalancing is in progress. In theory, no data should be
|
|
lost as rebalancing is a routine operation for Garage, although we cannot
|
|
guarantee you that everything will go right in such an extreme scenario.
|
|
|
|
#### `metadata_dir` {#metadata_dir}
|
|
|
|
The directory in which Garage will store its metadata. This contains the node identifier,
|
|
the network configuration and the peer list, the list of buckets and keys as well
|
|
as the index of all objects, object version and object blocks.
|
|
|
|
Store this folder on a fast SSD drive if possible to maximize Garage's performance.
|
|
|
|
#### `data_dir` {#data_dir}
|
|
|
|
The directory in which Garage will store the data blocks of objects.
|
|
This folder can be placed on an HDD. The space available for `data_dir`
|
|
should be counted to determine a node's capacity
|
|
when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
|
|
|
|
Since `v0.9.0`, Garage supports multiple data directories with the following syntax:
|
|
|
|
```toml
|
|
data_dir = [
|
|
{ path = "/path/to/old_data", read_only = true },
|
|
{ path = "/path/to/new_hdd1", capacity = "2T" },
|
|
{ path = "/path/to/new_hdd2", capacity = "4T" },
|
|
]
|
|
```
|
|
|
|
See [the dedicated documentation page](@/documentation/operations/multi-hdd.md)
|
|
on how to operate Garage in such a setup.
|
|
|
|
#### `db_engine` (since `v0.8.0`) {#db_engine}
|
|
|
|
Since `v0.8.0`, Garage can use alternative storage backends as follows:
|
|
|
|
| DB engine | `db_engine` value | Database path |
|
|
| --------- | ----------------- | ------------- |
|
|
| [LMDB](https://www.lmdb.tech) (default since `v0.9.0`) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
|
|
| [Sled](https://sled.rs) (default up to `v0.8.0`) | `"sled"` | `<metadata_dir>/db/` |
|
|
| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
|
|
|
|
Sled was the only database engine up to Garage v0.7.0. Performance issues and
|
|
API limitations of Sled prompted the addition of alternative engines in v0.8.0.
|
|
Since v0.9.0, LMDB is the default engine instead of Sled, and Sled is
|
|
deprecated. We plan to remove Sled in Garage v1.0.
|
|
|
|
Performance characteristics of the different DB engines are as follows:
|
|
|
|
- Sled: tends to produce large data files and also has performance issues,
|
|
especially when the metadata folder is on a traditional HDD and not on SSD.
|
|
|
|
- LMDB: the recommended database engine on 64-bit systems, much more
|
|
space-efficient and slightly faster. Note that the data format of LMDB is not
|
|
portable between architectures, so for instance the Garage database of an
|
|
x86-64 node cannot be moved to an ARM64 node. Also note that, while LMDB can
|
|
technically be used on 32-bit systems, this will limit your node to very
|
|
small database sizes due to how LMDB works; it is therefore not recommended.
|
|
|
|
- Sqlite: Garage supports Sqlite as an alternative storage backend for
|
|
metadata, and although it has not been tested as much, it is expected to work
|
|
satisfactorily. Since Garage v0.9.0, performance issues have largely been
|
|
fixed by allowing for a no-fsync mode (see `metadata_fsync`). Sqlite does not
|
|
have the database size limitation of LMDB on 32-bit systems.
|
|
|
|
It is possible to convert Garage's metadata directory from one format to another
|
|
using the `garage convert-db` command, which should be used as follows:
|
|
|
|
```
|
|
garage convert-db -a <input db engine> -i <input db path> \
|
|
-b <output db engine> -o <output db path>
|
|
```
|
|
|
|
Make sure to specify the full database path as presented in the table above
|
|
(third colummn), and not just the path to the metadata directory.
|
|
|
|
#### `metadata_fsync` {#metadata_fsync}
|
|
|
|
Whether to enable synchronous mode for the database engine or not.
|
|
This is disabled (`false`) by default.
|
|
|
|
This reduces the risk of metadata corruption in case of power failures,
|
|
at the cost of a significant drop in write performance,
|
|
as Garage will have to pause to sync data to disk much more often
|
|
(several times for API calls such as PutObject).
|
|
|
|
Using this option reduces the risk of simultaneous metadata corruption on several
|
|
cluster nodes, which could lead to data loss.
|
|
|
|
If multi-site replication is used, this option is most likely not necessary, as
|
|
it is extremely unlikely that two nodes in different locations will have a
|
|
power failure at the exact same time.
|
|
|
|
(Metadata corruption on a single node is not an issue, the corrupted data file
|
|
can always be deleted and reconstructed from the other nodes in the cluster.)
|
|
|
|
Here is how this option impacts the different database engines:
|
|
|
|
| Database | `metadata_fsync = false` (default) | `metadata_fsync = true` |
|
|
|----------|------------------------------------|-------------------------------|
|
|
| Sled | default options | *unsupported* |
|
|
| Sqlite | `PRAGMA synchronous = OFF` | `PRAGMA synchronous = NORMAL` |
|
|
| LMDB | `MDB_NOMETASYNC` + `MDB_NOSYNC` | `MDB_NOMETASYNC` |
|
|
|
|
Note that the Sqlite database is always ran in `WAL` mode (`PRAGMA journal_mode = WAL`).
|
|
|
|
#### `data_fsync` {#data_fsync}
|
|
|
|
Whether to `fsync` data blocks and their containing directory after they are
|
|
saved to disk.
|
|
This is disabled (`false`) by default.
|
|
|
|
This might reduce the risk that a data block is lost in rare
|
|
situations such as simultaneous node losing power,
|
|
at the cost of a moderate drop in write performance.
|
|
|
|
Similarly to `metatada_fsync`, this is likely not necessary
|
|
if geographical replication is used.
|
|
|
|
#### `block_size` {#block_size}
|
|
|
|
Garage splits stored objects in consecutive chunks of size `block_size`
|
|
(except the last one which might be smaller). The default size is 1MiB and
|
|
should work in most cases. We recommend increasing it to e.g. 10MiB if
|
|
you are using Garage to store large files and have fast network connections
|
|
between all nodes (e.g. 1gbps).
|
|
|
|
If you are interested in tuning this, feel free to do so (and remember to
|
|
report your findings to us!). When this value is changed for a running Garage
|
|
installation, only files newly uploaded will be affected. Previously uploaded
|
|
files will remain available. This however means that chunks from existing files
|
|
will not be deduplicated with chunks from newly uploaded files, meaning you
|
|
might use more storage space that is optimally possible.
|
|
|
|
#### `sled_cache_capacity` {#sled_cache_capacity}
|
|
|
|
This parameter can be used to tune the capacity of the cache used by
|
|
[sled](https://sled.rs), the database Garage uses internally to store metadata.
|
|
Tune this to fit the RAM you wish to make available to your Garage instance.
|
|
This value has a conservative default (128MB) so that Garage doesn't use too much
|
|
RAM by default, but feel free to increase this for higher performance.
|
|
|
|
#### `sled_flush_every_ms` {#sled_flush_every_ms}
|
|
|
|
This parameters can be used to tune the flushing interval of sled.
|
|
Increase this if sled is thrashing your SSD, at the risk of losing more data in case
|
|
of a power outage (though this should not matter much as data is replicated on other
|
|
nodes). The default value, 2000ms, should be appropriate for most use cases.
|
|
|
|
#### `lmdb_map_size` {#lmdb_map_size}
|
|
|
|
This parameters can be used to set the map size used by LMDB,
|
|
which is the size of the virtual memory region used for mapping the database file.
|
|
The value of this parameter is the maximum size the metadata database can take.
|
|
This value is not bound by the physical RAM size of the machine running Garage.
|
|
If not specified, it defaults to 1GiB on 32-bit machines and 1TiB on 64-bit machines.
|
|
|
|
#### `compression_level` {#compression_level}
|
|
|
|
Zstd compression level to use for storing blocks.
|
|
|
|
Values between `1` (faster compression) and `19` (smaller file) are standard compression
|
|
levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
|
|
used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
|
|
default value (currently `3`). Finally, zstd has also compression designed to be faster
|
|
than default compression levels, they range from `-1` (smaller file) to `-99` (faster
|
|
compression).
|
|
|
|
If you do not specify a `compression_level` entry, Garage will set it to `1` for you. With
|
|
this parameters, zstd consumes low amount of cpu and should work faster than line speed in
|
|
most situations, while saving some space and intra-cluster
|
|
bandwidth.
|
|
|
|
If you want to totally deactivate zstd in Garage, you can pass the special value `'none'`. No
|
|
zstd related code will be called, your chunks will be stored on disk without any processing.
|
|
|
|
Compression is done synchronously, setting a value too high will add latency to write queries.
|
|
|
|
This value can be different between nodes, compression is done by the node which receive the
|
|
API call.
|
|
|
|
#### `rpc_secret`, `rpc_secret_file` or `GARAGE_RPC_SECRET`, `GARAGE_RPC_SECRET_FILE` (env) {#rpc_secret}
|
|
|
|
Garage uses a secret key, called an RPC secret, that is shared between all
|
|
nodes of the cluster in order to identify these nodes and allow them to
|
|
communicate together. The RPC secret is a 32-byte hex-encoded random string,
|
|
which can be generated with a command such as `openssl rand -hex 32`.
|
|
|
|
The RPC secret should be specified in the `rpc_secret` configuration variable.
|
|
Since Garage `v0.8.2`, the RPC secret can also be stored in a file whose path is
|
|
given in the configuration variable `rpc_secret_file`, or specified as an
|
|
environment variable `GARAGE_RPC_SECRET`.
|
|
|
|
Since Garage `v0.8.5` and `v0.9.1`, you can also specify the path of a file
|
|
storing the secret as the `GARAGE_RPC_SECRET_FILE` environment variable.
|
|
|
|
#### `rpc_bind_addr` {#rpc_bind_addr}
|
|
|
|
The address and port on which to bind for inter-cluster communcations
|
|
(reffered to as RPC for remote procedure calls).
|
|
The port specified here should be the same one that other nodes will used to contact
|
|
the node, even in the case of a NAT: the NAT should be configured to forward the external
|
|
port number to the same internal port nubmer. This means that if you have several nodes running
|
|
behind a NAT, they should each use a different RPC port number.
|
|
|
|
#### `rpc_bind_outgoing` {#rpc_bind_outgoing} (since v0.9.2)
|
|
|
|
If enabled, pre-bind all sockets for outgoing connections to the same IP address
|
|
used for listening (the IP address specified in `rpc_bind_addr`) before
|
|
trying to connect to remote nodes.
|
|
This can be necessary if a node has multiple IP addresses,
|
|
but only one is allowed or able to reach the other nodes,
|
|
for instance due to firewall rules or specific routing configuration.
|
|
|
|
Disabled by default.
|
|
|
|
#### `rpc_public_addr` {#rpc_public_addr}
|
|
|
|
The address and port that other nodes need to use to contact this node for
|
|
RPC calls. **This parameter is optional but recommended.** In case you have
|
|
a NAT that binds the RPC port to a port that is different on your public IP,
|
|
this field might help making it work.
|
|
|
|
#### `bootstrap_peers` {#bootstrap_peers}
|
|
|
|
A list of peer identifiers on which to contact other Garage peers of this cluster.
|
|
These peer identifiers have the following syntax:
|
|
|
|
```
|
|
<node public key>@<node public IP or hostname>:<port>
|
|
```
|
|
|
|
In the case where `rpc_public_addr` is correctly specified in the
|
|
configuration file, the full identifier of a node including IP and port can
|
|
be obtained by running `garage node id` and then included directly in the
|
|
`bootstrap_peers` list of other nodes. Otherwise, only the node's public
|
|
key will be returned by `garage node id` and you will have to add the IP
|
|
yourself.
|
|
|
|
### `allow_world_readable_secrets`
|
|
|
|
Garage checks the permissions of your secret files to make sure they're not
|
|
world-readable. In some cases, the check might fail and consider your files as
|
|
world-readable even if they're not, for instance when using Posix ACLs.
|
|
|
|
Setting `allow_world_readable_secrets` to `true` bypass this
|
|
permission verification.
|
|
|
|
Alternatively, you can set the `GARAGE_ALLOW_WORLD_READABLE_SECRETS`
|
|
environment variable to `true` to bypass the permissions check.
|
|
|
|
### The `[consul_discovery]` section
|
|
|
|
Garage supports discovering other nodes of the cluster using Consul. For this
|
|
to work correctly, nodes need to know their IP address by which they can be
|
|
reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
|
|
|
|
#### `consul_http_addr` {#consul_http_addr}
|
|
|
|
The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server.
|
|
|
|
#### `api` {#consul_api}
|
|
|
|
Two APIs for service registration are supported: `catalog` and `agent`. `catalog`, the default, will register a service using
|
|
the `/v1/catalog` endpoints, enabling mTLS if `client_cert` and `client_key` are provided. The `agent` API uses the
|
|
`v1/agent` endpoints instead, where an optional `token` may be provided.
|
|
|
|
#### `service_name` {#consul_service_name}
|
|
|
|
`service_name` should be set to the service name under which Garage's
|
|
RPC ports are announced.
|
|
|
|
#### `client_cert`, `client_key` {#consul_client_cert_and_key}
|
|
|
|
TLS client certificate and client key to use when communicating with Consul over TLS. Both are mandatory when doing so.
|
|
Only available when `api = "catalog"`.
|
|
|
|
#### `ca_cert` {#consul_ca_cert}
|
|
|
|
TLS CA certificate to use when communicating with Consul over TLS.
|
|
|
|
#### `tls_skip_verify` {#consul_tls_skip_verify}
|
|
|
|
Skip server hostname verification in TLS handshake.
|
|
`ca_cert` is ignored when this is set.
|
|
|
|
#### `token` {#consul_token}
|
|
|
|
Uses the provided token for communication with Consul. Only available when `api = "agent"`.
|
|
The policy assigned to this token should at least have these rules:
|
|
|
|
```hcl
|
|
// the `service_name` specified above
|
|
service "garage" {
|
|
policy = "write"
|
|
}
|
|
|
|
service_prefix "" {
|
|
policy = "read"
|
|
}
|
|
|
|
node_prefix "" {
|
|
policy = "read"
|
|
}
|
|
```
|
|
|
|
#### `tags` and `meta` {#consul_tags_and_meta}
|
|
|
|
Additional list of tags and map of service meta to add during service registration.
|
|
|
|
### The `[kubernetes_discovery]` section
|
|
|
|
Garage supports discovering other nodes of the cluster using kubernetes custom
|
|
resources. For this to work, a `[kubernetes_discovery]` section must be present
|
|
with at least the `namespace` and `service_name` parameters.
|
|
|
|
#### `namespace` {#kube_namespace}
|
|
|
|
`namespace` sets the namespace in which the custom resources are
|
|
configured.
|
|
|
|
#### `service_name` {#kube_service_name}
|
|
|
|
`service_name` is added as a label to the advertised resources to
|
|
filter them, to allow for multiple deployments in a single namespace.
|
|
|
|
#### `skip_crd` {#kube_skip_crd}
|
|
|
|
`skip_crd` can be set to true to disable the automatic creation and
|
|
patching of the `garagenodes.deuxfleurs.fr` CRD. You will need to create the CRD
|
|
manually.
|
|
|
|
|
|
### The `[s3_api]` section
|
|
|
|
#### `api_bind_addr` {#s3_api_bind_addr}
|
|
|
|
The IP and port on which to bind for accepting S3 API calls.
|
|
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
|
|
|
|
Alternatively, since `v0.8.5`, a path can be used to create a unix socket with 0222 mode.
|
|
|
|
#### `s3_region` {#s3_region}
|
|
|
|
Garage will accept S3 API calls that are targetted to the S3 region defined here.
|
|
API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
|
|
message that redirects the client to the correct region.
|
|
|
|
#### `root_domain` {#s3_root_domain}
|
|
|
|
The optional suffix to access bucket using vhost-style in addition to path-style request.
|
|
Note path-style requests are always enabled, whether or not vhost-style is configured.
|
|
Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
|
|
but might be required by softwares not supporting path-style requests.
|
|
|
|
If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
|
|
using the hostname `my-bucket.s3.garage.eu`.
|
|
|
|
|
|
|
|
### The `[s3_web]` section
|
|
|
|
Garage allows to publish content of buckets as websites. This section configures the
|
|
behaviour of this module.
|
|
|
|
#### `bind_addr` {#web_bind_addr}
|
|
|
|
The IP and port on which to bind for accepting HTTP requests to buckets configured
|
|
for website access.
|
|
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
|
|
|
|
Alternatively, since `v0.8.5`, a path can be used to create a unix socket with 0222 mode.
|
|
|
|
#### `root_domain` {#web_root_domain}
|
|
|
|
The optional suffix appended to bucket names for the corresponding HTTP Host.
|
|
|
|
For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
|
|
will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
|
|
or with hostname `deuxfleurs.fr`.
|
|
|
|
|
|
### The `[admin]` section
|
|
|
|
Garage has a few administration capabilities, in particular to allow remote monitoring. These features are detailed below.
|
|
|
|
#### `api_bind_addr` {#admin_api_bind_addr}
|
|
|
|
If specified, Garage will bind an HTTP server to this port and address, on
|
|
which it will listen to requests for administration features.
|
|
See [administration API reference](@/documentation/reference-manual/admin-api.md) to learn more about these features.
|
|
|
|
Alternatively, since `v0.8.5`, a path can be used to create a unix socket. Note that for security reasons,
|
|
the socket will have 0220 mode. Make sure to set user and group permissions accordingly.
|
|
|
|
#### `metrics_token`, `metrics_token_file` or `GARAGE_METRICS_TOKEN`, `GARAGE_METRICS_TOKEN_FILE` (env) {#admin_metrics_token}
|
|
|
|
The token for accessing the Metrics endpoint. If this token is not set, the
|
|
Metrics endpoint can be accessed without access control.
|
|
|
|
You can use any random string for this value. We recommend generating a random token with `openssl rand -base64 32`.
|
|
|
|
`metrics_token` was introduced in Garage `v0.7.2`.
|
|
`metrics_token_file` and the `GARAGE_METRICS_TOKEN` environment variable are supported since Garage `v0.8.2`.
|
|
|
|
`GARAGE_METRICS_TOKEN_FILE` is supported since `v0.8.5` / `v0.9.1`.
|
|
|
|
#### `admin_token`, `admin_token_file` or `GARAGE_ADMIN_TOKEN`, `GARAGE_ADMIN_TOKEN_FILE` (env) {#admin_token}
|
|
|
|
The token for accessing all of the other administration endpoints. If this
|
|
token is not set, access to these endpoints is disabled entirely.
|
|
|
|
You can use any random string for this value. We recommend generating a random token with `openssl rand -base64 32`.
|
|
|
|
`admin_token` was introduced in Garage `v0.7.2`.
|
|
`admin_token_file` and the `GARAGE_ADMIN_TOKEN` environment variable are supported since Garage `v0.8.2`.
|
|
|
|
`GARAGE_ADMIN_TOKEN_FILE` is supported since `v0.8.5` / `v0.9.1`.
|
|
|
|
#### `trace_sink` {#admin_trace_sink}
|
|
|
|
Optionally, the address of an OpenTelemetry collector. If specified,
|
|
Garage will send traces in the OpenTelemetry format to this endpoint. These
|
|
trace allow to inspect Garage's operation when it handles S3 API requests.
|
