Hello devs,
In my project I wanted to make every OpenVZ container to use for a
private directory (VE_PRIVATE) separated block device (HDD partition,
lvm volume, NFS share, etc.). To use wrapper script over vzctl was one
option, but PRE_CREATE hook, in which to create, mkfs and mount LVM
volume would be even better.
So, I'm not a developer, but using code from POST_CREATE hook I was
able to create the PRE_CREATE one, which can be used as the other
hooks e.g.
add in /etc/vz/dists/ default
PRE_CREATE = precreate.sh
and during
vzctl --create ...
it will call /etc/vz/dists/scripts/precreate.sh with VEID as argument
Nope. These scripts are per-distribution scripts, i.e. they are targeted for
various distro-specific things, such as setting IP addresses etc.
What you need is a global script, not dependent on CT distro. I suggest
a precreate.sh script similar to prestart.sh one (for details, see commit
https://github.com/kolyshkin/vzctl/commit/0807ef4)
Currently I have a patch to vzctl master branch which implements this
PRE_CREATE hook and I'm ready to share it.
So my questions are:
- Do you find this for interesting and/or useful?
- If 'yes', what is the right way to send this patch: here, by email;
or to create pull request in git repo?
The best way would be to redo as advised above and send a patch to
devel@ list.
Thanks,
Kir.
Best regards!
