Runtimevar Source

The runtimevar source is a source for the Go Cloud runtimevar package

This package takes a driver.Watcher and then allows you to use it as a backend source. We expect the Snapshot value to be []byte. We use the built in encoder to decode the value. This defaults to json.

Example

A runtimevar config format in json

{
    "hosts": {
        "database": {
            "address": "10.0.0.1",
            "port": 3306
        },
        "cache": {
            "address": "10.0.0.2",
            "port": 6379
        }
    }
}

New Source

Specify runtimevar source with watcher. It will panic if not specified.

srv := runtimevar.NewSource(
	runtimevar.WithDriver(dv),
)

Config Format

To load different runtimevar formats e.g yaml, toml, xml you must specify an encoder

e := toml.NewEncoder()

src := runtimevar.NewSource(
        runtimevar.WithDriver(dv),
	source.WithEncoder(e),
)

Load Source

Load the source into config

// Create new config
conf := config.NewConfig()

// Load runtimevar source
conf.Load(src)
