pflask
|
||||
======
|
||||
|

:target: https://travis-ci.org/ghedo/pflask
|
||||
|
||||
pflask_ is a simple tool for creating process containers on LInux. It can be
|
||||
used for running single commands or even booting a whole operating system
|
||||
inside an isolated environment, where the filesystem hierarchy, networking,
|
||||
process tree, IPC subsystems and host/domain name can be insulated from the
|
||||
host system and other containers.
|
||||
|
||||
.. _pflask: https://ghedo.github.io/pflask
|
||||
|
||||
Getting Started
|
||||
---------------
|
||||
|
||||
pflask doesn't need any configuration and can be run without any arguments
|
||||
as follows:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask
|
||||
|
||||
By default a new container will be created and a bash shell will be started,
|
||||
but a custom command can also be specified:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask -- id
|
||||
uid=0(root) gid=0(root) gruppi=0(root)
|
||||
|
||||
The container can also be run inside a private root directory by using the
|
||||
``--chroot`` option:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs -- id
|
||||
uid=0(root) gid=0(root) gruppi=0(root)
|
||||
|
||||
This can be used, for example, as a replacement for the ``chroot(8)`` command.
|
||||
It's even possible to invoke the init binary and boot the whole operating
|
||||
system inside the container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs -- /sbin/init
|
||||
|
||||
Note that pflask doesn't provide any support for creating the rootfs, but can
|
||||
piggyback on existing tools. For example the ``debootstrap(8)`` command can be
|
||||
used for creating a Debian rootfs as follows:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo debootstrap sid /path/to/rootfs http://httpredir.debian.org/debian
|
||||
|
||||
For more information on pflask usage, have a look at the `man page`_.
|
||||
|
||||
.. _`man page`: https://ghedo.github.io/pflask/pflask.html
|
||||
|
||||
Networking
|
||||
~~~~~~~~~~
|
||||
|
||||
Using the ``--netif`` option the networking of the container will be
|
||||
disconnected from the host system and all network interfaces will be made
|
||||
unavailable to the container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --netif -- ip link
|
||||
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
|
||||
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||||
|
||||
The ``--netif`` option can also be used to create private network interfaces:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --netif=macvlan:eth0:net0 -- ip link
|
||||
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
|
||||
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||||
5: net0@if2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default
|
||||
link/ether 92:e4:c2:9b:a4:75 brd ff:ff:ff:ff:ff:ff link-netnsid 0
|
||||
|
||||
Interfaces created inside the container will be automatically destroyed once
|
||||
the container terminates.
|
||||
|
||||
The command above will create a new ``macvlan`` interface called ``net0``, from
|
||||
the ``eth0`` host interface. ``macvlan`` interfaces can be used to give an
|
||||
additional MAC address to a network adapter and make it look like a completely
|
||||
different device.
|
||||
|
||||
pflask can also create other `types of network interfaces`_, have a look at the
|
||||
manpage for more information.
|
||||
|
||||
.. _`types of network interfaces`: https://ghedo.github.io/pflask/pflask.html#netif
|
||||
|
||||
Filesystem
|
||||
~~~~~~~~~~
|
||||
|
||||
By default a new mount namespace is created for the container, so that
|
||||
filesystems mounted inside it won't affect the host system. The ``--mount``
|
||||
option can then be used to create new mount points before the execution of the
|
||||
supplied command.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs --mount=bind:/tmp:/tmp
|
||||
|
||||
The command above will bind mount the host's ``/tmp`` directory into the
|
||||
container's ``/tmp``, so that files can be exchanged between them.
|
||||
|
||||
pflask can also create other `types of mount points`_, have a look at the
|
||||
manpage for more information.
|
||||
|
||||
.. _`types of mount points`: https://ghedo.github.io/pflask/pflask.html#mount
|
||||
|
||||
Additionally, using the ``--ephemeral`` option it's possible to tell pflask to
|
||||
discard any change applied to the root filesystem once the container terminates:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs --ephemeral -- /sbin/init
|
||||
|
||||
This can be used for example for a build environment, where dependencies can
|
||||
be installed at every run on a clean rootfs, without the need to recreate the
|
||||
rootfs every time.
|
||||
|
||||
Unprivileged containers
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
All the commands above have been executed with root privileges, but pflask can
|
||||
be invoked, with some limitations, by unprivileged users as well, as long as
|
||||
user namespaces are supported by the host system.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ pflask --user=$USER -- id
|
||||
uid=1000(ghedo) gid=1000(ghedo) gruppi=1000(ghedo)
|
||||
|
||||
For example, on recent Debian versions user namespaces are enabled, but are
|
||||
restricted to the root user only. To enable them for unprivileged users run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo sysctl kernel.unprivileged_userns_clone=1
|
||||
|
||||
This functionality can be used to run every-day user applications such as a
|
||||
web browser inside a container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ pflask --user=$USER --mount=tmp:$HOME -- chromium --disable-setuid-sandbox
|
||||
|
||||
The command above uses the ``--mount`` option to create a ``tmpfs`` mount point
|
||||
on the ``$HOME`` directory, so that the application (chromium in the example)
|
||||
won't be able to access the user's private files, and any modification to the
|
||||
home directory will be discarded once the container terminates.
|
||||
|
||||
The ``--chroot`` option can be used with unprivileged containers as well, but
|
||||
requires some additional configuration.
|
||||
|
||||
The first step is assigning a set of additional UIDs and GIDs to the current
|
||||
user (``$USER``). These will be used by pflask inside the container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo usermod --add-subuids 100000-165535 $USER
|
||||
$ sudo usermod --add-subgids 100000-165535 $USER
|
||||
|
||||
Note that the commands above require root privileges, but have to be run only
|
||||
once.
|
||||
|
||||
Then any time an unprivileged ``chroot(8)`` is needed, the following command
|
||||
can be run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ pflask --user-map=0:100000:65536 --chroot=/path/to/rootfs
|
||||
|
||||
Note that the ``newuidmap(1)`` and ``newgidmap(1)`` commands need to be
|
||||
installed for any of this to work: on Debian/Ubuntu systems they are provided
|
||||
by the ``uidmap`` package.
|
||||
|
||||
Background containers
|
||||
~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Containers can be detached from the current terminal as soon as they are
|
||||
created by using the ``--detach`` option:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs --detach
|
||||
|
||||
and then later reattached (even to a different terminal) with the ``--attach``
|
||||
option:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ pidof pflask
|
||||
29076
|
||||
$ pflask --attach=29076
|
||||
|
||||
Where ``29076`` is the PID of the detached pflask process. Once reattached, it
|
||||
can be detached again by pressing ``^@`` (Ctrl + @).
|
||||
|
||||
machined integration
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Containers created with pflask are automatically registered with the machined_
|
||||
daemon, if installed and running. The ``machinectl(1)`` command can then be
|
||||
used to list and manipulate running containers.
|
||||
|
||||
Let's create one container as follows:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pflask --chroot=/path/to/rootfs -- /sbin/init
|
||||
|
||||
Running containers can be listed using the ``list`` command:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ machinectl --no-pager list
|
||||
MACHINE CLASS SERVICE
|
||||
pflask-19170 container pflask
|
||||
|
||||
1 machines listed.
|
||||
|
||||
and information regarding a single container can be retrieved with the ``show``
|
||||
command:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ machinectl --no-pager show pflask-19170
|
||||

||||

|

|
||||
|

Additionally, the ``status`` command will show more information regarding the
|
||||
status of the container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ machinectl --no-pager status pflask-19170

|
||||
|

One can even log into the container using the ``login`` command (note that
|
||||
the dbus daemon needs to be running inside the container for this to work):
|
||||
|
||||
.. code-block:: bash
|

kronk login:
|
||||
|
||||
And finally the container can be terminated using either the ``poweroff`` or
|
||||
``terminate`` commands:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||

CAPABILITIES
|
||||
------------
|
||||
|
||||
pflask can modify the set of capabilties enabled for the container using the
|
||||
``--caps`` option.
|
||||
|
||||
This takes a list of comma-separated capability names, optionally prefixed by
|
||||
``+`` (to add the capability to the set) or ``-`` (to drop the capability from
|
||||
the set).
|
||||
|
||||
Valid capability names are the same name as defined in <linux/capabilities.h>
|
||||
with the ``CAP_`` prefix removed. The string case does not matter. The first
|
||||
specified capability name can be the alias 'all' to specify either a full or
|
||||
an empty initial set. Container processes will start by default with a full
|
||||
set e.g. ``--caps=all``.
|
||||
|
||||
Full set example: ``--caps=all,-chown,-setuid,-setgid`` or equivalently ``--caps=-chown,-setuid,-setgid``
|
||||
|
||||
Empty set example: ``--caps=-all,+chown``

/*

* This file contains macros to manipulate singly and doubly-linked lists.
|
||||
*
|
||||
* 1. LL_ macros: singly-linked lists.
|
||||
* 2. DL_ macros: doubly-linked lists.
|
||||
* 3. CDL_ macros: circular doubly-linked lists.
|
||||
*
|
||||
* To use singly-linked lists, your structure must have a "next" pointer.
|
||||
* To use doubly-linked lists, your structure must "prev" and "next" pointers.
|
||||
* Either way, the pointer to the head of the list must be initialized to NULL.
|
||||
*
|
||||
* ----------------.EXAMPLE -------------------------
|
||||
* struct item {
|
||||
* int id;
|
||||
* struct item *prev, *next;
|
||||
* }
|
||||
*
|
||||
* struct item *list = NULL:
|
||||
*
|
||||
* int main() {
|
||||
* struct item *item;
|
||||
* ... allocate and populate item ...
|
||||
* DL_APPEND(list, item);
|
||||
* }
|
||||
* --------------------------------------------------
|
||||
*
|
||||
* For doubly-linked lists, the append and delete macros are O(1)
|
||||
* For singly-linked lists, append and delete are O(n) but prepend is O(1)
|
||||
* The sort macro is O(n log(n)) for all types of single/double/circular lists.

<p><a class="reference external" href="https://ghedo.github.io/pflask">pflask</a> is a simple tool for creating process containers on LInux. It can be
|
||||
used for running single commands or even booting a whole operating system
|
||||
inside an isolated environment, where the filesystem hierarchy, networking,
|
||||
process tree, IPC subsystems and host/domain name can be insulated from the
|
||||
host system and other containers.</p>

|
||||
<h2>Getting Started<a class="headerlink" href="#getting-started" title="Permalink to this headline">¶</a></h2>
|
||||
<p>pflask doesn’t need any configuration and can be run without any arguments
|
||||
as follows:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>By default a new container will be created and a bash shell will be started,
|
||||
but a custom command can also be specified:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask -- id
|
||||
<span class="nv">uid</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span> <span class="nv">gid</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span> <span class="nv">gruppi</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>The container can also be run inside a private root directory by using the
|
||||
<tt class="docutils literal"><span class="pre">--chroot</span></tt> option:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --chroot<span class="o">=</span>/path/to/rootfs -- id
|
||||
<span class="nv">uid</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span> <span class="nv">gid</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span> <span class="nv">gruppi</span><span class="o">=</span>0<span class="o">(</span>root<span class="o">)</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>This can be used, for example, as a replacement for the <tt class="docutils literal"><span class="pre">chroot(8)</span></tt> command.
|
||||
It’s even possible to invoke the init binary and boot the whole operating
|
||||
system inside the container:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --chroot<span class="o">=</span>/path/to/rootfs -- /sbin/init
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Note that pflask doesn’t provide any support for creating the rootfs, but can
|
||||
piggyback on existing tools. For example the <tt class="docutils literal"><span class="pre">debootstrap(8)</span></tt> command can be
|
||||
used for creating a Debian rootfs as follows:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo debootstrap sid /path/to/rootfs http://httpredir.debian.org/debian
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>For more information on pflask usage, have a look at the <a class="reference external" href="https://ghedo.github.io/pflask/pflask.html">man page</a>.</p>
|
||||
<div class="section" id="networking">
|
||||
<h3>Networking<a class="headerlink" href="#networking" title="Permalink to this headline">¶</a></h3>
|
||||
<p>Using the <tt class="docutils literal"><span class="pre">--netif</span></tt> option the networking of the container will be
|
||||
disconnected from the host system and all network interfaces will be made
|
||||
unavailable to the container:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --netif -- ip link
|
||||
1: lo: <LOOPBACK,UP,LOWER_UP> mtu <span class="m">65536</span> qdisc noqueue state UNKNOWN mode DEFAULT group default
|
||||
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>The <tt class="docutils literal"><span class="pre">--netif</span></tt> option can also be used to create private network interfaces:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --netif<span class="o">=</span>macvlan:eth0:net0 -- ip link
|
||||
1: lo: <LOOPBACK,UP,LOWER_UP> mtu <span class="m">65536</span> qdisc noqueue state UNKNOWN mode DEFAULT group default
|
||||
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
|
||||
5: net0@if2: <BROADCAST,MULTICAST> mtu <span class="m">1500</span> qdisc noop state DOWN mode DEFAULT group default
|
||||
link/ether 92:e4:c2:9b:a4:75 brd ff:ff:ff:ff:ff:ff link-netnsid 0
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Interfaces created inside the container will be automatically destroyed once
|
||||
the container terminates.</p>
|
||||
<p>The command above will create a new <tt class="docutils literal"><span class="pre">macvlan</span></tt> interface called <tt class="docutils literal"><span class="pre">net0</span></tt>, from
|
||||
the <tt class="docutils literal"><span class="pre">eth0</span></tt> host interface. <tt class="docutils literal"><span class="pre">macvlan</span></tt> interfaces can be used to give an
|
||||
additional MAC address to a network adapter and make it look like a completely
|
||||
different device.</p>
|
||||
<p>pflask can also create other <a class="reference external" href="https://ghedo.github.io/pflask/pflask.html#netif">types of network interfaces</a>, have a look at the
|
||||
manpage for more information.</p>
|
||||
</div>
|
||||
<div class="section" id="filesystem">
|
||||
<h3>Filesystem<a class="headerlink" href="#filesystem" title="Permalink to this headline">¶</a></h3>
|
||||
<p>By default a new mount namespace is created for the container, so that
|
||||
filesystems mounted inside it won’t affect the host system. The <tt class="docutils literal"><span class="pre">--mount</span></tt>
|
||||
option can then be used to create new mount points before the execution of the
|
||||
supplied command.</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --chroot<span class="o">=</span>/path/to/rootfs --mount<span class="o">=</span><span class="nb">bind</span>:/tmp:/tmp
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>The command above will bind mount the host’s <tt class="docutils literal"><span class="pre">/tmp</span></tt> directory into the
|
||||
container’s <tt class="docutils literal"><span class="pre">/tmp</span></tt>, so that files can be exchanged between them.</p>
|
||||
<p>pflask can also create other <a class="reference external" href="https://ghedo.github.io/pflask/pflask.html#mount">types of mount points</a>, have a look at the
|
||||
manpage for more information.</p>
|
||||
<p>Additionally, using the <tt class="docutils literal"><span class="pre">--ephemeral</span></tt> option it’s possible to tell pflask to
|
||||
discard any change applied to the root filesystem once the container terminates:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo pflask --chroot<span class="o">=</span>/path/to/rootfs --ephemeral -- /sbin/init
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>This can be used for example for a build environment, where dependencies can
|
||||
be installed at every run on a clean rootfs, without the need to recreate the
|
||||
rootfs every time.</p>
|
||||
</div>
|
||||
<div class="section" id="unprivileged-containers">
|
||||
<h3>Unprivileged containers<a class="headerlink" href="#unprivileged-containers" title="Permalink to this headline">¶</a></h3>
|
||||
<p>All the commands above have been executed with root privileges, but pflask can
|
||||
be invoked, with some limitations, by unprivileged users as well, as long as
|
||||
user namespaces are supported by the host system.</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>pflask --user<span class="o">=</span><span class="nv">$USER</span> -- id
|
||||
<span class="nv">uid</span><span class="o">=</span>1000<span class="o">(</span>ghedo<span class="o">)</span> <span class="nv">gid</span><span class="o">=</span>1000<span class="o">(</span>ghedo<span class="o">)</span> <span class="nv">gruppi</span><span class="o">=</span>1000<span class="o">(</span>ghedo<span class="o">)</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>For example, on recent Debian versions user namespaces are enabled, but are
|
||||
restricted to the root user only. To enable them for unprivileged users run:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo sysctl kernel.unprivileged_userns_clone<span class="o">=</span>1
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>This functionality can be used to run every-day user applications such as a
|
||||
web browser inside a container:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>pflask --user<span class="o">=</span><span class="nv">$USER</span> --mount<span class="o">=</span>tmp:<span class="nv">$HOME</span> -- chromium --disable-setuid-sandbox
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>The command above uses the <tt class="docutils literal"><span class="pre">--mount</span></tt> option to create a <tt class="docutils literal"><span class="pre">tmpfs</span></tt> mount point
|
||||
on the <tt class="docutils literal"><span class="pre">$HOME</span></tt> directory, so that the application (chromium in the example)
|
||||
won’t be able to access the user’s private files, and any modification to the
|
||||
home directory will be discarded once the container terminates.</p>
|
||||
<p>The <tt class="docutils literal"><span class="pre">--chroot</span></tt> option can be used with unprivileged containers as well, but
|
||||
requires some additional configuration.</p>
|
||||
<p>The first step is assigning a set of additional UIDs and GIDs to the current
|
||||
user (<tt class="docutils literal"><span class="pre">$USER</span></tt>). These will be used by pflask inside the container:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>sudo usermod --add-subuids 100000-165535 <span class="nv">$USER</span>
|
||||
<span class="nv">$ </span>sudo usermod --add-subgids 100000-165535 <span class="nv">$USER</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Note that the commands above require root privileges, but have to be run only
|
||||
once.</p>
|
||||
<p>Then any time an unprivileged <tt class="docutils literal"><span class="pre">chroot(8)</span></tt> is needed, the following command
|
||||
can be run:</p>
|
||||
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>pflask --user-map<span class="o">=</span>0:100000:65536 --chroot<span class="o">=</span>/path/to/rootfs
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Note that the <tt class="docutils literal"><span class="pre">newuidmap(1)</span></tt> and <tt class="docutils literal"><span class="pre">newgidmap(1)</span></tt> commands need to be
|
||||
installed for any of this to work: on Debian/Ubuntu systems they are provided
|
||||
by the <tt class="docutils literal"><span class="pre">uidmap</span></tt> package.</p>
|

</div>
|

<div class="section" id="background-containers">
|

<h3>Background containers<a class="headerlink" href="#background-containers" title="Permalink to this headline">¶</a></h3>
|

<p>Containers can be detached from the current terminal as soon as they are

created by using the <tt class="docutils literal"><span class="pre">--detach</span></tt> option:</p>

<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
|

<p><strong>pflask</strong> is a simple tool for creating process containers on LInux. It can be
|
||||
used for running single commands or even booting a whole operating system
|
||||
inside an isolated environment, where the filesystem hierarchy, networking,
|
||||
process tree, IPC subsystems and host/domain name can be insulated from the
|
||||
host system and other containers.</p>

<h2>MOUNT<a class="headerlink" href="#mount" title="Permalink to this headline">¶</a></h2>
|
||||
<p>pflask can create the following mount point types using the <tt class="docutils literal"><span class="pre">--mount</span></tt> option:</p>
|
||||
<div class="section" id="bind">
|
||||
<h3>bind<a class="headerlink" href="#bind" title="Permalink to this headline">¶</a></h3>
|
||||
<p><tt class="docutils literal"><span class="pre">--mount=bind:<host_path>:<container_path></span></tt></p>
|
||||
<p>Bind mounts the <em>host_path</em> directory/file on the host filesystem to the
|
||||
<em>container_path</em> directory/file in the container. If the <tt class="docutils literal"><span class="pre">--chroot</span></tt> option is
|
||||
used, the destination path will be relative to the chroot directory.</p>
|
||||
<p>Example: <tt class="docutils literal"><span class="pre">--mount=bind:/source/path:/dest/path</span></tt></p>
|
||||
</div>
|
||||
<div class="section" id="bind-ro">
|
||||
<h3>bind-ro<a class="headerlink" href="#bind-ro" title="Permalink to this headline">¶</a></h3>
|
||||
<p><tt class="docutils literal"><span class="pre">--mount=bind-ro:<host_path>:<container_path></span></tt></p>
|
||||
<p>Same as <tt class="docutils literal"><span class="pre">bind</span></tt>, but makes the mount point read-only. If the <tt class="docutils literal"><span class="pre">--chroot</span></tt>
|
||||
option is used, the destination path will be relative to the chroot directory.</p>
|
||||
<p>Example: <tt class="docutils literal"><span class="pre">--mount=bind-ro:/source/path:/dest/path</span></tt></p>
|
||||
</div>
|
||||
<div class="section" id="overlay">
|

<h3>overlay<a class="headerlink" href="#overlay" title="Permalink to this headline">¶</a></h3>
|
||||
<p><tt class="docutils literal"><span class="pre">--mount=overla:<root_dir>:<dest>:<work_dir></span></tt></p>
|
||||
<p>Stacks the host <em>root_dir</em> directory on top of the container’s <em>dest</em> directory
|
||||
using either AuFS or OverlayFS depending on what is found at compile-time. If
|
||||
the <tt class="docutils literal"><span class="pre">--chroot</span></tt> option is used, the destination path will be relative to the
|
||||
chroot directory. The <em>work_dir</em> directory needs to be an empty directory on
|
||||
the same filesystem as <em>root_dir</em>.</p>
|
||||
<p>Note that AuFS and OverlayFS don’t support user namespaces, so the <tt class="docutils literal"><span class="pre">--user</span></tt>
|
||||
option is incompatible with this mount type unless <tt class="docutils literal"><span class="pre">--no-userns</span></tt> is also used.</p>
|

<p>Example: <tt class="docutils literal"><span class="pre">--mount=overlay:/overlay/path:/dest/path:/overlay/work</span></tt></p>

<p><tt class="docutils literal"><span class="pre">--mount=tmp:<dest></span></tt></p>
|

<p>Mounts a temporary in-memory filesystem on the <em>dest</em> directory inside the

<p>pflask will create a new network namespace when the <tt class="docutils literal"><span class="pre">--netif</span></tt> option is used.
|

If one of the following arguments is provided, a network interface will also be

|

<p>Moves the <em>dev</em> network interface from the host to the container, and renames

it to <em>name</em>. No additional configuration will be applied to it.</p>

<p>Creates a <tt class="docutils literal"><span class="pre">macvlan</span></tt> network interface using <em>master</em> as master interface,
|

moves it inside the container and renames it to <em>name</em>. No additional

<p><tt class="docutils literal"><span class="pre">--netif=veth:<name_outside>:<name_inside></span></tt></p>
|

<p>Creates a pair of <tt class="docutils literal"><span class="pre">veth</span></tt> network interfaces called <em>name_outside</em> and
