Hi everybody.
I would like to use lxc to serve HA for Web service. I've done a POC with an
ubuntu 16.04.
2 containers with ephemeral option running nginx. Each of running container
mount different /var/www/html directory to serve different default page. This 2
containers names are site1 and site2. The template is debian/stretch/amd64.
1 container runs haproxy configured to check site1 and site2 as backend.
Lxc-net is configured to send static ip to the 3 containers.
My failover test is :- access haproxy with http client multitimes :ok- stop
container site2 :ok- haproxy access still working :ok- run new site2 container.
:ok- test haproxy with http client :KO
=> /o fails, the site2 get request from haproxy but doesn't reply.
On site2, the arp table doesn't contain haproxy entry. Everything comes ok if I
ping haproxy from site2 container. The arp table is ok and site2 replies
normaly.
Is this a bug or a known issue ? In lxc or in debian's template ?
Thanks a lot for your answers.
