Guest Operating System Configuration
|
|
||||||
------------------------------------
|
|
||||||
|
|
||||||
{pve} tries to detect the Linux distribution in the container, and modifies
|
|
||||||
some files. Here is a short list of things done at container startup:
|
|
||||||
|
|
||||||
set /etc/hostname:: to set the container name
|
|
||||||
|
|
||||||
modify /etc/hosts:: to allow lookup of the local hostname
|
|
||||||
|
|
||||||
network setup:: pass the complete network setup to the container
|
|
||||||
|
|
||||||
configure DNS:: pass information about DNS servers
|
|
||||||
|
|
||||||
adapt the init system:: for example, fix the number of spawned getty processes
|
|
||||||
|
|
||||||
set the root password:: when creating a new container
|
|
||||||
|
|
||||||
rewrite ssh_host_keys:: so that each container has unique keys
|
|
||||||
|
|
||||||
randomize crontab:: so that cron does not start at the same time on all containers
|
|
||||||

Those markers will be inserted at a reasonable location in the file. If such a
|
|
||||||
section already exists, it will be updated in place and will not be moved.
|
|
||||||
|
|
||||||
Modification of a file can be prevented by adding a `.pve-ignore.` file for it.
|
|
||||||
For instance, if the file `/etc/.pve-ignore.hosts` exists then the `/etc/hosts`
|
|
||||||
file will not be touched. This can be a simple empty file created via:
|
|
||||||
|
|
||||||
----
|
|
||||||
# touch /etc/.pve-ignore.hosts
|
|
||||||
----
|
|
||||||
|
|
||||||
Most modifications are OS dependent, so they differ between different
|
|
||||||
distributions and versions. You can completely disable modifications by
|
|
||||||
manually setting the `ostype` to `unmanaged`.
|
|
||||||
|
|
||||||
OS type detection is done by testing for certain files inside the
|
|
||||||
container:
|
|
||||||
|
|
||||||
Ubuntu:: inspect /etc/lsb-release (`DISTRIB_ID=Ubuntu`)
|
|
||||||
|
|
||||||
Debian:: test /etc/debian_version
|
|
||||||
|
|
||||||
Fedora:: test /etc/fedora-release
|
|
||||||
|
|
||||||
RedHat or CentOS:: test /etc/redhat-release
|
|
||||||
|
|
||||||
ArchLinux:: test /etc/arch-release
|
|
||||||
|
|
||||||
Alpine:: test /etc/alpine-release
|
|
||||||
|
|
||||||
Gentoo:: test /etc/gentoo-release
|
|
||||||
|
|
||||||
NOTE: Container start fails if the configured `ostype` differs from the auto
|
|
||||||
detected type.
