salt.states.lxc¶

Manage Linux Containers¶

salt.states.lxc.absent(name, stop=False)¶

Ensure a container is not present, destroying it if present

name

Name of the container to destroy

stop

stop before destroying default: false

New in version 2015.5.2.

web01:
  lxc.absent

salt.states.lxc.cloned(name, orig, snapshot=True, size=None, vgname=None, profile=None)¶

Deprecated since version 2015.5.0: Use lxc.present

salt.states.lxc.created(name, **kwargs)¶

Deprecated since version 2015.5.0: Use lxc.present

salt.states.lxc.edited_conf(name, lxc_conf=None, lxc_conf_unset=None)¶

Warning

This state is unsuitable for setting parameters that appear more than once in an LXC config file, or parameters which must appear in a certain order (such as when configuring more than one network interface). It is slated to be replaced, and as of version 2015.5.0 it is deprecated.

Edit LXC configuration options

setconf:
  lxc.edited_conf:
    - name: ubuntu
    - lxc_conf:
        - network.ipv4.ip: 10.0.3.6
    - lxc_conf_unset:
        - lxc.utsname

salt.states.lxc.frozen(name, start=True)¶

New in version 2015.5.0.

Ensure that a container is frozen

Note

This state does not enforce the existence of the named container, it just freezes the container if it is running. To ensure that the named container exists, use lxc.present.

name

The name of the container

start : True

Start container first, if necessary. If False, then this state will fail if the container is not running.

web01:
  lxc.frozen

web02:
  lxc.frozen:
    - start: False

salt.states.lxc.present(name, running=None, clone_from=None, snapshot=False, profile=None, network_profile=None, template=None, options=None, image=None, config=None, fstype=None, size=None, backing=None, vgname=None, lvname=None)¶

Changed in version 2015.5.0: The lxc.created state has been renamed to lxc.present, and the lxc.cloned state has been merged into this state.

Create the named container if it does not exist

name

The name of the container to be created

running : False

• If True, ensure that the container is running
• If False, ensure that the container is stopped
• If None, do nothing with regards to the running state of the container

New in version 2015.5.0.

clone_from

Create named container as a clone of the specified container

snapshot : False

Use Copy On Write snapshots (LVM). Only supported with clone_from.

profile

Profile to use in container creation (see the LXC Tutorial for more information). Values in a profile will be overridden by the parameters listed below.

network_profile

Network Profile to use in container creation (see the LXC Tutorial for more information). Values in a profile will be overridden by the parameters listed below.

New in version 2015.5.2.

Container Creation Arguments

template

The template to use. E.g., 'ubuntu' or 'fedora'. Conflicts with the image argument.

Note

The download template requires the following three parameters to be defined in options:

• dist - The name of the distribution
• release - Release name/version
• arch - Architecture of the container

The available images can be listed using the lxc.images function.

options

New in version 2015.5.0.

Template-specific options to pass to the lxc-create command. These correspond to the long options (ones beginning with two dashes) that the template script accepts. For example:

web01:
  lxc.present:
    - template: download
    - options:
        dist: centos
        release: 6
        arch: amd64

Remember to double-indent the options, due to how PyYAML works.

image

A tar archive to use as the rootfs for the container. Conflicts with the template argument.

backing

The type of storage to use. Set to lvm to use an LVM group. Defaults to filesystem within /var/lib/lxc.

fstype

Filesystem type to use on LVM logical volume

size

Size of the volume to create. Only applicable if backing is set to lvm.

vgname : lxc

Name of the LVM volume group in which to create the volume for this container. Only applicable if backing is set to lvm.

lvname

Name of the LVM logical volume in which to create the volume for this container. Only applicable if backing is set to lvm.

salt.states.lxc.running(name, restart=False)¶

Changed in version 2015.5.0: The lxc.started state has been renamed to lxc.running

Ensure that a container is running

Note

This state does not enforce the existence of the named container, it just starts the container if it is not running. To ensure that the named container exists, use lxc.present.

name

The name of the container

restart : False

Restart container if it is already running

web01:
  lxc.running

web02:
  lxc.running:
    - restart: True

salt.states.lxc.set_pass(name, **kwargs)¶

Deprecated since version 2015.5.0.

This state function has been disabled, as it did not conform to design guidelines. Specifically, due to the fact that lxc.set_password uses chpasswd(8) to set the password, there was no method to make this action idempotent (in other words, the password would be changed every time). This makes this state redundant, since the following state will do the same thing:

setpass:
  module.run:
    - name: set_pass
    - m_name: root
    - password: secret

salt.states.lxc.started(name, restart=False)¶

Deprecated since version 2015.5.0: Use lxc.running

salt.states.lxc.stopped(name, kill=False)¶

Ensure that a container is stopped

Note

This state does not enforce the existence of the named container, it just stops the container if it running or frozen. To ensure that the named container exists, use lxc.present, or use the lxc.absent state to ensure that the container does not exist.

name

The name of the container

kill : False

Do not wait for the container to stop, kill all tasks in the container. Older LXC versions will stop containers like this irrespective of this argument.

New in version 2015.5.0.
