Send a Slack message to a channel from a Cloud Build step

Description

This uses https://github.com/technosophos/slack-notify to send Slack messages

Usage

cr_buildstep_slack(
  message,
  title = "CloudBuild - $BUILD_ID",
  channel = NULL,
  username = "googleCloudRunnerBot",
  webhook = "$_SLACK_WEBHOOK",
  icon = NULL,
  colour = "#efefef"
)

Arguments

message	The body of the message
title	The title of the message
channel	The channel to send the message to (if omitted, use Slack-configured default)
username	The name of the sender of the message. Does not need to be a "real" username
webhook	The Slack webhook to send to
icon	A URL to an icon (squares between 512px and 2000px)
colour	The RGB colour for message formatting

Details

You will need to set up a Slack webhook first, via this Slack guide on using incoming webhooks.

Once set, the default is to set this webhook to a Build macro called _SLACK_WEBHOOK, or supply it to the webhook argument.
