There are situations where it would be advantageous to let
an operator specify custom per-service options.
One such use case seen in the wild is to extend the timeout of the cinder
because due to the specific storage backend these cinder operations
sometimes take a bit longer. Letting the user tweak the
haproxy_default_timeout is likely not what we want as for the case
above we only want to tweak a single service.
We explored another approach to fix this by adding a bunch of
<service>_options class parameters in the tripleo::haproxy class but it
made it extremely bloated and confusing, so we opted for this approach
which is much less invasive both code-wise and complexity-wise
Tested by deploying with:
ExtraConfig:
tripleo::haproxy::cinder::options:
"timeout client": '90m'
'timeout server': '90m'
And observing the following cinder haproxy stanza:
listen cinder
bind 10.0.0.4:8776 transparent
bind 172.16.2.9:8776 transparent
mode http
http-request set-header X-Forwarded-Proto https if { ssl_fc }
http-request set-header X-Forwarded-Proto http if !{ ssl_fc }
option httpchk
option httplog
timeout client 90m
timeout server 90m
server overcloud-controller-0.internalapi.localdomain 172.16.2.7:8776 check fall 5 inter 2000 rise 2
server overcloud-controller-1.internalapi.localdomain 172.16.2.16:8776 check fall 5 inter 2000 rise 2
server overcloud-controller-2.internalapi.localdomain 172.16.2.13:8776 check fall 5 inter 2000 rise 2

- |
|
|
Add support via hiera keys like 'tripleo::haproxy::${name}::listen_options' to
|
|
customize the options of an haproxy service stanza. For example passing the by setting
|
|
the 'tripleo::haproxy::cinder::options' hiera key to a hash made composed of:
|
|
'timeout client': '90m'
|
|
'timeout server': '90m'
