# Scaleway config

## TL;DR

Recommended config file:

```yaml
# Get your credentials on https://console.scaleway.com/project/credentials
access_key: SCWXXXXXXXXXXXXXXXXX
secret_key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
default_organization_id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
default_project_id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
default_region: fr-par
default_zone: fr-par-1
```

## Config file path

The function [`GetConfigPath`](https://godoc.org/github.com/scaleway/scaleway-sdk-go/scw#GetConfigPath) will try to locate the config file in the following ways:

1. Custom directory: `$SCW_CONFIG_PATH`
2. [XDG base directory](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html): `$XDG_CONFIG_HOME/scw/config.yaml`
3. Unix home directory: `$HOME/.config/scw/config.yaml`
4. Windows home directory: `%USERPROFILE%/.config/scw/config.yaml`

## Reading config order

[ClientOption](https://godoc.org/github.com/scaleway/scaleway-sdk-go/scw#ClientOption) ordering will decide the order in which the config should apply:

```go
p, _ := scw.MustLoadConfig().GetActiveProfile()

scw.NewClient(
    scw.WithProfile(p),                     // active profile applies first
    scw.WithEnv(),                          // existing env variables may overwrite active profile
    scw.WithDefaultRegion(scw.RegionFrPar)  // any prior region set will be discarded to usr the new one
)
```
