Removal of key-value pair from viper config file

Is there a way to remove a key/value pair from the loaded config file?

viper.Set("key", nil)

does not work

Solution

  • Try

    delete(viper.Get("path.to.key").(map[string]interface{}), "key")

    Example:

    [backends]
  [backends.setibe]
    [backends.setibe.servers]
      [backends.setibe.servers.server0]
      url = "http://192.168.1.20:80"
      weight = 1
      [backends.setibe.servers.server1]
      url = "http://192.168.1.21:80"
      weight = 1

    To delete "backends.setibe.servers.server1"

    delete(viper.Get("backends.setibe.servers").(map[string]interface{}), "server2")
