Capability to manually add attributes to spans

[cyrille-leclerc]

Problem description

I want to manually add attributes to spans in my pipeline, similar to manually adding attributes to spans when instrumenting applications with distributed tracing.

Example use cases

• Add informations on shell steps to indicate the purpose of the shell step (e.g. an sh 'docker login -u $user -p $pass my.docker.registry')
  • ❓ How to add attributes to atomic built-in steps ("non wrapping steps") like the sh step?

Exemple with the OpenTelemetry APIs for Java

Span currentSpan = Span.current();
currentSpan.setAttribute(""net.peer.name", "my.docker.registry");
currentSpan.setAttribute(""rpc.service", "docker");
currentSpan.setAttribute(""rpc.method", "login");

• Capability to add "logs" to spans #92

Proposed solutions

addAttributes() pipeline step

adding an attributes attribute to the built-in steps

I think this is already supported by using these steps:

• withSpanAttribute(key, value[, type][, target])
• setSpanAttributes([spanAttribute(key, value[, type][, target])])
• withSpanAttributes([spanAttribute(key, value[, type][, target])])
