Prerequisites

• Currently only supports Linux and MacOS
• You must have a standalone binary of tracepusher in your path (ie. you are able to run tracepusher from the command line and see output)
• You must have an OpenTelemetry collector somewhere so the spans can be sent there

Install Plugin

helm plugin install https://github.com/agardnerit/helm-trace

Use the Plugin

1. Ensure you have an OpenTelemetry Collector available
2. Add the word trace after helm in your standard command. For example helm version becomes helm trace version

Defaults and Configuration

The plugin assumes the following:

• The OTEL collector URL defaults to http://localhost:4318
• The span service name defaults to helm

Use environment variable: HT_OTELCOL_ENDPOINT to specify your collector endpoint

Use environment variable: HT_SERVICE_NAME to specify a different service name

export HT_OTEL_ENDPOINT=http://otelcol.somewhere.com:4318
export HT_OTEL_ENDPOINT=helm-dev
helm trace install ...

Remove Plugin

helm plugin remove trace

helm-trace's Issues

Simplify time calculation logic

In 0.1.0 the time logic is a little redundant. We use time_start=0 and thus duration is always "some value minus 0" which can be simplified just be saying duration=$SECONDS.
