httpd logs hidden inside containers

[Derek Higgins]

Of the httpd containerized services that I looked at, none of them have /var/log/httpd listed in volumes, so logs don't appear in /var/log/containers on the host.

Note, that fits the current (intermediate) implementation for containers logging, see https://review.openstack.org/#/c/462900/7/specs/pike/containerized-services-logs.rst@50

We could export them to bare metal in according to what we do with services that use the traditional logging (line 80 in the spec).

Just wondering what would be the best directory... /var/log/containers/$SERVICE/httpd/ might be the best in terms of hierarchy, but i don't think it's doable without some somersaults, because we do a lot of `chown -R ... /var/log/containers/$SERVICE` which would also chown the httpd subdir in a way we don't want.

Considering the above, i'd probably go for something like

/var/log/containers/$SERVICE-httpd/

[Bogdan Dobrelya (bogdando)]

Or we could configure httpd to log into syslog

Sadly, we can't send httpd logs from containers to syslog. We need httpd 2.5 to have the mod_syslog.so, but "Apache httpd v2.5 is currently not included in any Red Hat product"
