What did you expect to see?

Please add a feature to mirror/shadow incoming traffic to two sets of endpoints and be able to configure which amount goes where...e.g., something like this:

@kenyee I’ve actually started working on a PR, but given time constraints not sure I’ll finish before the March 20th cutoff for the 1.6 release, so most likely will be added in 1.7. :(

Cool...thanks @aantono :-)

If we build on the backend system we already have, I suppose it might look like something like this:

...
    --label "traefik.port=80" \
    --label "traefik.frontend.rule=Host:site1.example.org" \
    --label "traefik.enable=true" \
    --label "traefik.backend=backend-nextversion" \
    --label "traefik.mirror.enable=true" \
    --label "traefik.mirror.percentage=10" \
...

In this manner, there's ALREADY a frontend for site1.example.org, it already exists, it's already working.

• traefik.mirror.enable suggests that Traefik will ignore/drop any responses generated from the mirror.
• traefik.mirror.percentage is the amount of traffic to mirror, default 100/all.

Attempting to bring up a traefik.mirror.enable on a not-yet-defined traefik.frontend.rule SHOULD NOT ERROR. We may wish to only mirror a subdirectory of a site, or the mirror container may have started first. Thus we might want to at least WARN.

Hello folks,

Just a friendly ping to understand where this feature is standing. Not urgent for me but it would be a nice to have in a near future (I'd rather not switch to something else if I can help it :)).

Thanks for all the great product!

Hello Traefik team! We really need this feature. Is there a chance that this feature would be in the future releases?

Is there any further progress on this? We currently use traefik but need to find a way to shadowing or similar and are starting to look at alternatives. A timeframe would be very useful if this is a WIP. Thank you!
