Hi,
I hit a few issues while performing a recent HE install of 4.3. While I managed
to find solutions/workarounds to all the problems I thought I might share them
here
* As defined in the Ansible defaults the temp dir for building the local HE VM
is /var/tmp. I was 80M short of the required space and there did not appear to
be a (supported) way to specify a different location. I ended up having to do a
bind mount of /var/tmp to get me through the install. Would be nice to be able
to specify a custom location.
* Permissive umask required. Our CIS CentOS 7 build requires that default umask
is 027. This breaks the installer as it creates the VM image under /var/tmp as
root and cannot then access it as qemu user. As the temp files are cleaned up
on failure it took me a while to track this one down. My solution was to
temporarily set the umask to 022 for the session while running the installer.
It would be nice if the installer either handled this by doing a chmod/chown as
required, or at least doing a umask pre-check and failing with a meaningful
error.
* SSH root login required on host. Again for CIS we have "PermitRoologin no"
configured in sshd. This means the add host task fails on the Engine, but
instead of a hard failure we get a timeout on the installer. Which left me
chasing some imagined routing/bridging/DNS issue. Eventually I realised I could
get to the engine logs and found the issue but took several hours. Would be
nice if the installer could either support a sudo option or at least perform a
root login pre-check and fail with a meaningful error.
Thanks,
Alan
