# Litestream {#module-services-litestream}
|
||
|
|
|
||
|
|
[Litestream](https://litestream.io/) is a standalone streaming
|
||
|
|
replication tool for SQLite.
|
||
|
|
|
||
|
|
## Configuration {#module-services-litestream-configuration}
|
||
|
|
|
||
|
|
Litestream service is managed by a dedicated user named `litestream`
|
||
|
|
which needs permission to the database file. Here's an example config which gives
|
||
|
|
required permissions to access [grafana database](#opt-services.grafana.settings.database.path):
|
||
|
|
```
|
||
|
|
{ pkgs, ... }:
|
||
|
|
{
|
||
|
|
users.users.litestream.extraGroups = [ "grafana" ];
|
||
|
|
|
||
|
|
systemd.services.grafana.serviceConfig.ExecStartPost = "+" + pkgs.writeShellScript "grant-grafana-permissions" ''
|
||
|
|
timeout=10
|
||
|
|
|
||
|
|
while [ ! -f /var/lib/grafana/data/grafana.db ];
|
||
|
|
do
|
||
|
|
if [ "$timeout" == 0 ]; then
|
||
|
|
echo "ERROR: Timeout while waiting for /var/lib/grafana/data/grafana.db."
|
||
|
|
exit 1
|
||
|
|
fi
|
||
|
|
|
||
|
|
sleep 1
|
||
|
|
|
||
|
|
((timeout--))
|
||
|
|
done
|
||
|
|
|
||
|
|
find /var/lib/grafana -type d -exec chmod -v 775 {} \;
|
||
|
|
find /var/lib/grafana -type f -exec chmod -v 660 {} \;
|
||
|
|
'';
|
||
|
|
|
||
|
|
services.litestream = {
|
||
|
|
enable = true;
|
||
|
|
|
||
|
|
environmentFile = "/run/secrets/litestream";
|
||
|
|
|
||
|
|
settings = {
|
||
|
|
dbs = [
|
||
|
|
{
|
||
|
|
path = "/var/lib/grafana/data/grafana.db";
|
||
|
|
replicas = [{
|
||
|

url = "s3://mybkt.litestream.io/grafana";
|

}

];
|

};
|
||
|
|
};
|

}
|
