New user here. I have a Go plugin that works fine. Now I would like to be able to have the plugin load some static settings when it initializes as well as save some state to persistent storage. For saving state I assume the Storage module is the way to go, but I haven’t seen any nice way to load settings. I could of course load and parse a file myself from a hard coded location, but I would like to avoid that if possible. Ideally I would like to append my own settings to the file given to Nakama via the `--config` flag.
Is there anything obvious I’m missing?

Seems the storage engine always requires a “user id” with stored data. Can’t really find any API docs for the Go plugin runtime, but this seems to be the case. My settings aren’t specific to a single user, but instead global for the entire server.

Apparently you should be able to get all server config from the context using the `RUNTIME_CTX_ENV` key. At least the docs say:
> A table of key/value pairs which are defined in the YAML [configuration](https://heroiclabs.com/docs/nakama/getting-started/configuration/) of the server. This is useful to store API keys and other secrets which may be different between servers run in production and in development.
This looks promising. So I add in the following to the file `local.yaml` which is given to the server when starting:
```yaml
# other settings
...
my_data:
my_key1: 1
my_key2: 42
```
I start the server as:
```bash
% ./nakama --config ./local.yml
```
I then try to get these settings with:
```go
func InitModule(ctx context.Context, logger runtime.Logger, db *sql.DB, nk runtime.NakamaModule, initializer runtime.Initializer) error {
logger.Info("Initializing module")
config, ok := ctx.Value(runtime.RUNTIME_CTX_ENV).(map[string]string)
if !ok {
return errors.New("invalid context")
}
logger.Info("config: %v, %d", config, len(config))
...
```
But `config` is always empty. Is there something I don’t grok here, or is this not how it should work? I’m new at using Go, so it may be a stupid noob mistake too.

Not sure about the Nakama version, this looks wrong to me:
```bash
% git branch
* (HEAD detached at v3.4.0)
master
% ./nakama --version
3.0.0+dev
```
Is the `version` in `main.go` not updated or am I holding this wrong?

What you’re looking for is the [runtime environment configuration](https://heroiclabs.com/docs/nakama/getting-started/configuration/#runtime). You can specify key-value pairs in Nakama’s configuration:
```auto
runtime:
env:
- "FOO=bar"
- "BAZ=qux"
```
And read them in the runtime (Go example):
```auto
func InitModule(ctx context.Context, logger runtime.Logger, db *sql.DB, nk runtime.NakamaModule, initializer runtime.Initializer) error {
env := ctx.Value(runtime.RUNTIME_CTX_ENV).(map[string]string)
logger.Info(env["FOO"]) // Prints: bar
}
```

The version is not set if you build from source. We recommend using one of the official [releases](https://github.com/heroiclabs/nakama/releases) or [Docker images](https://hub.docker.com/r/heroiclabs/nakama) where possible.

Thank you for clearing this up. I spent a long time trying various ways to get settings in and was about to start parsing an own config file. To me the below documentation for `runtime.env` did not tell me that this is what I should use…
