docker buildx history trace

DescriptionShow the OpenTelemetry trace of a build record
Usagedocker buildx history trace [OPTIONS] [REF]

Description

View the OpenTelemetry trace for a completed build. This command loads the trace into a Jaeger UI viewer and opens it in your browser.

This helps analyze build performance, step timing, and internal execution flows.

Options

OptionDefaultDescription
--addr127.0.0.1:0Address to bind the UI server
--compareCompare with another build record

Examples

Open the OpenTelemetry trace for the most recent build

This command starts a temporary Jaeger UI server and opens your default browser to view the trace.

docker buildx history trace

Open the trace for a specific build

# Using a build ID
docker buildx history trace qu2gsuo8ejqrwdfii23xkkckt

# Or using a relative offset
docker buildx history trace ^1

Run the Jaeger UI on a specific port (--addr)

# Using a build ID
docker buildx history trace qu2gsuo8ejqrwdfii23xkkckt --addr 127.0.0.1:16686

# Or using a relative offset
docker buildx history trace ^1 --addr 127.0.0.1:16686

Compare two build traces (--compare)

Compare two specific builds by name:

# Using build IDs
docker buildx history trace --compare=qu2gsuo8ejqrwdfii23xkkckt qsiifiuf1ad9pa9qvppc0z1l3

# Or using a single relative offset
docker buildx history trace --compare=^1

When you use a single reference with --compare, it compares that build against the most recent one.
