Backport
This PR is auto-generated from #12862 to be assessed for backporting due to the inclusion of the label backport/1.3.x.
WARNING automatic cherry-pick of commits failed. Commits will require human attention.
The below text is copied from the body of the original PR.
This PR adds the
?choose
query parameter to the/v1/service/<service>
endpoint.The value of
choose
is in the form<number>|<key>
, number is the numberof desired services and key is a value unique but consistent to the requester
(e.g.
allocID
).Folks aren't really expected to use this API directly, but rather through
consul-template
/template
blockwhich will soon be getting a new helper function making use of this query parameter.
Example,
curl 'localhost:4646/v1/service/redis?choose=2|abc123'
Part of #12575
Because this also includes updating CT, the
template
part works now as well.
