Package polaris implements GoFrame gcfg.Adapter using polaris service.
go get -u github.com/gogf/gf/contrib/config/polaris/v2
If you wish using configuration from polaris globally, it is strongly recommended creating a custom boot package in very top import, which sets the Adapter of default configuration instance before any other package boots.
package boot
import (
"github.com/gogf/gf/contrib/config/polaris/v2"
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gctx"
)
func init() {
var (
ctx = gctx.GetInitCtx()
namespace = "default"
fileGroup = "goframe"
fileName = "config.yaml"
path = "testdata/polaris.yaml"
logDir = "/tmp/polaris/log"
)
// Create polaris Client that implements gcfg.Adapter.
adapter, err := polaris.New(ctx, polaris.Config{
Namespace: namespace,
FileGroup: fileGroup,
FileName: fileName,
Path: path,
LogDir: logDir,
Watch: true,
})
if err != nil {
g.Log().Fatalf(ctx, `%+v`, err)
}
// Change the adapter of default configuration instance.
g.Cfg().SetAdapter(adapter)
}It is strongly recommended import your boot package in top of your main.go.
Note the top import: _ "github.com/gogf/gf/example/config/polaris/boot" .
package main
import (
_ "github.com/gogf/gf/example/config/polaris/boot"
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gctx"
)
func main() {
var ctx = gctx.GetInitCtx()
// Available checks.
g.Dump(g.Cfg().Available(ctx))
// All key-value configurations.
g.Dump(g.Cfg().Data(ctx))
// Retrieve certain value by key.
g.Dump(g.Cfg().MustGet(ctx, "server.address"))
