Runtimevar Source

The runtimevar source is a source for the Go Cloud Development Kit runtimevar package.

This package takes a runtimevar.Variable and then allows you to use it as a backend source. When constructing your runtimevar.Variable, use the gocloud.dev/runtimevar.BytesDecoder decoder to allow your Snapshot value to be []byte. We then use the built in go-config encoder to decode the value. This defaults to json.

New Source

Specify a runtimevar source with the Go CDK runtimevar.Variable. It will panic if not specified.

// See https://godoc.org/gocloud.dev/runtimevar for examples on how to create
// a gocloud.dev/runtimevar.Varible. Use a BytesDecoder.
srv := runtimevar.NewSource(
	runtimevar.WithVariable(v),
)

Config Format

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

e := toml.NewEncoder()

src := runtimevar.NewSource(
        runtimevar.WithVariable(v),
	source.WithEncoder(e),
)

Load Source

Load the source into config

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

// Load runtimevar source
conf.Load(src)
