Dynamic log links #4774

eapolinario · 2024-01-24T20:43:42Z

Tracking issue

Why are the changes needed?

We need a way to specify dynamic log links from tasks as defined in the linked tracking issue. This PR implements this idea. Essentially operators are going to add a section to their config files for specific dynamic log links. For example, we have flyin as a plugin that would benefit from this feature.

What changes were proposed in this pull request?

We add a new subsection to the plugin section in the propeller config file that lets users specify dynamic plugins. The template uris for these dynamic plugins can be configured similarly to the usual plugins, the only difference that specific fields can be plucked from the task template to be used in the template uri. Take this example:

plugins:
  logs:
    dynamic-log-links-enabled: true
    dynamic-log-links:
      vscode: http://flyteinteractve.vs:{{ .taskConfig.port }}/{{ .podName }}

Notice how in the template uri for the vscode dynamic plugin we access the port (which is defined in a task template metadata) using the prefix .taskConfig, whereas the usual template variables are also available.

How was this patch tested?

Unit tests and tested locally in a sandbox.

@EngHabu , as we talked about yesterday, this next batch of updates implements:

remove enabled flag
do not hardcode port
- In fact, we now let users match any value set in the task template config
Use vscode as the name of the log
Add name to TemplateLogPlugin to help distinguish which plugin is used
- Remove =DynamicTemplateURI=
Get rid of Schemes

+			tasklog.TemplateLogPlugin{
+				Name:        logLinkType,
+				DisplayName: fmt.Sprintf("%s logs", logLinkType),
+				DynamicTemplateURIs: []tasklog.TemplateURI{


Is this field still needed? can't we use TemplateURIs...

This simplifies the distinction between task logs produced by dynamic log links vs regular log links.

For example, let's say we enable one dynamic log link in propeller. How do we make sure that dynamic log links only show up for tasks that have the right bits set in their task templates?

Does it not have a MessageFormat field?

nit: Would be nice to support this for the "regular" logs as well...

It will be easy to rearrange this logic when we find a good use-case for regular logs.
