cli Source
The cli source reads config from parsed flags via a cli.Context.
Format
We expect the use of the micro/cli package. Upper case flags will be lower cased. Dashes will be used as delimiters for nesting.
Example
micro.Flags(
cli.StringFlag{
Name: "database-address",
Value: "127.0.0.1",
Usage: "the db address",
},
cli.IntFlag{
Name: "database-port",
Value: 3306,
Usage: "the db port",
},
)
Becomes
{
"database": {
"address": "127.0.0.1",
"port": 3306
}
}
New and Load Source
Because a cli.Context is needed to retrieve the flags and their values, it is recommended to build your source from within a cli.Action.
func main() {
// New Service
service := micro.NewService(
micro.Name("example"),
micro.Flags(
cli.StringFlag{
Name: "database-address",
Value: "127.0.0.1",
Usage: "the db address",
},
),
)
var clisrc source.Source
service.Init(
micro.Action(func(c *cli.Context) {
clisrc = cli.NewSource(
cli.Context(c),
)
// Alternatively, just setup your config right here
}),
)
// ... Load and use that source ...
conf := config.NewConfig()
conf.Load(clisrc)
}
