It might be misleading/confusing to display the UI project version rather than the backend release version (which implies a certain UI version).

+1. We may need to supply release version to the CONFIG here

jaeger-ui/packages/jaeger-ui/public/index.html

Lines 18 to 27 in 2a55237

	// Jaeger UI config data is embedded by the query-service. This is
	// later merged with defaults into the redux `state.config` via
	// src/utils/config/get-config.js. The default provided by the query
	// service should be an empty object or it can leave `DEFAULT_CONFIG`
	// unchanged.
	function getJaegerUiConfig() {
	const DEFAULT_CONFIG = null;
	const JAEGER_CONFIG = DEFAULT_CONFIG;
	return JAEGER_CONFIG;
	}

This is replaced in server code with a JSON object.

Finally got some time to come back to this -- gave it a shot in jaegertracing/jaeger#2406

[yurishkuro]

alternative solution that does not touch the config: jaegertracing/jaeger#2547

[yurishkuro]

Would you like to give it another try? If you sync to jaeger-ui/master, the index.html now gets the following top level function:

// Jaeger version data is embedded by the query-service via search/replace.
function getJaegerVersion() {
  const DEFAULT_VERSION = {"gitCommit":"", "gitVersion":"", "buildDate":""};
  const JAEGER_VERSION = {"gitCommit":"0f88343172c0bb16ad5c1805d18e20d59176ea7e","gitVersion":"v1.20.0","buildDate":"2020-10-09T17:42:48Z"};
  return JAEGER_VERSION;
}

Considering that there are several data elements here, I would recommend adding them at the bottom of the About menu, e.g.

• Jaeger v1.20.0
• Commit 2a55237
• Build 2020-10-09T17:42:48Z
• Jaeger UI v1.9.0

[alanisaac]

Made the updates as requested, though this does make an assumption about the correct short hash for git being 7 characters. While this is the default, my understanding is that's not always the case if there are collisions and ambiguity.

I think the more technically correct way to get the short hash might be to use git rev-parse --short <SHA> at the source and inject it instead, though this would involve more changes on the Jaeger query side.

On a side note, in testing with Jaeger, I found that the default recommended way to run of make run-all-in-one does not include the $(BUILD_INFO) necessary to inject the version information, so the query version info in the about menu appears blank when running via this method. Is this desired or not? For convenience in my own local testing I temporarily added $(BUILD_INFO) to the command.

[yurishkuro]

Looks awesome. One other idea I had is to make versions actually clickable, to that vN.N.N links would take you to the respective release notes page and the commit hash to that commit (the latter is less important than the versions). But this can be done in a separate PR, I would like to merge this first.

Regarding make run-all-in-one, sounds like something we could improve in the make target, although when running from a local copy getting the versions is a bit fuzzy.

[yurishkuro]

Thanks a lot!
