Currently, we require that config file names end with `.yml` or `.yaml`.
This is because if the user points `-config` at a directory of files, we
only want to use the YAML files in that directory.
But this makes it more difficult to use the `-test -config` option
because config management tools might not have an extension on the file
when preparing a new config file. This change makes it so that if you
point `-config file` directly at a file, it uses it no matter what the
extension is.
This change introduces logging.timestamp_format, which allows
configuration of the Logrus TimestampFormat setting. The primary purpose
of this change was to allow logging with millisecond precision. The
default for `text` and `json` formats remains the same for backwards
compatibility.
timestamp format is specified in Go time format, see:
- https://golang.org/pkg/time/#pkg-constants
Default when `format: json`: "2006-01-02T15:04:05Z07:00" (RFC3339)
Default when `format: text`:
when TTY attached: seconds since beginning of execution
otherwise: "2006-01-02T15:04:05Z07:00" (RFC3339)
As an example, to log as RFC3339 with millisecond precision, set to:
logging:
timestamp_format: "2006-01-02T15:04:05.000Z07:00"
