Services
processes are a low-level interface to starting a tool, while services provide a higher level configuration.
Here's an example starting PostgreSQL with a few extensions:
devenv.nix
{ pkgs, ... }:
{
services.postgres = {
enable = true;
package = pkgs.postgresql_15;
initialDatabases = [{ name = "mydb"; }];
extensions = extensions: [
extensions.postgis
extensions.timescaledb
];
settings.shared_preload_libraries = "timescaledb";
initialScript = "CREATE EXTENSION IF NOT EXISTS timescaledb;";
};
}
Services start like processes with devenv up
:
Service states are persisted to directories in $DEVENV_STATE
. When you adjust options like the above used initialScript
, you will have to delete the service's directory for changes to take effect on next devenv up
.
Services in the background
Services start in the foreground by default. If you want to start services up in the background, you can pass the -d
flag:
