Add a new --export-stdout flag that enables the tetragon agent to write JSON events directly to its stdout, bypassing file-based export and the sidecar container. This reduces operational complexity for users who prefer inline event logs. Note that when this option is enabled the normal logs are directed to stderr to avoid interleaving with the stream of events. Signed-off-by: irozzo-1A <iacopo@sysdig.com>
Add a new export.mode value "direct-stdout" that writes events directly to the tetragon container stdout without a sidecar or host volume. The existing "stdout" mode (sidecar-based file export) remains the default. Signed-off-by: irozzo-1A <iacopo@sysdig.com>
✅ Deploy Preview for tetragon ready!

Fixes #1710
Description
Add a new
--export-stdoutflag that writes JSON events directly to the Tetragon agent's stdout instead of a file. In Kubernetes, this is exposed asexport.mode: direct-stdoutin the Helm chart, which removes the need for a sidecar container and an export-logs host volume.When active, agent logs are automatically redirected to stderr to avoid interleaving with the event stream. The flag is mutually exclusive with
--export-filenameand--export-file-rotation-interval. The existingstdout(sidecar-based) mode remains the Helm default for now.Changelog
