<title>Methods</title>
|
|
|
|
<para><function>GetImage()</function> may be used to get the image object path of the image with the
|
|
specified name.</para>
|
|
|
|
<para><function>ListImages()</function> returns an array of all currently known images. The
|
|
structures in the array consist of the following fields: image name, type, read-only flag, creation
|
|
time, modification time, current disk space, usage and image object path.</para>
|
|
|
|
<para><function>GetImageOSRelease()</function> retrieves the OS release information of an image.
|
|
This method returns an array of key value pairs read from the
|
|
<citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry> file in
|
|
the image and is useful to identify the operating system used in a portable service.</para>
|
|
|
|
<para><function>GetImageMetadata()</function> retrieves metadata associated with an image.
|
|
This method returns the image name, the image's <citerefentry><refentrytitle>os-release</refentrytitle>
|
|
<manvolnum>5</manvolnum></citerefentry> content in the form of a (streamable) array of bytes,
|
|
and a list of portable units contained in the image, in the form of a string (unit name) and
|
|
an array of bytes with the content.</para>
|
|
|
|
<para><function>GetImageMetadataWithExtensions()</function> retrieves metadata associated with an image.
|
|
This method is a superset of <function>GetImageMetadata()</function> with the addition of
|
|
a list of extensions as input parameter, which were overlaid on top of the main
|
|
image via <function>AttachImageWithExtensions()</function>.
|
|
The <varname>flag</varname> parameter is currently unused and reserved for future purposes.</para>
|
|
|
|
<para><function>GetImageState()</function> retrieves the image state as one of the following
|
|
strings:
|
|
<itemizedlist>
|
|
<listitem><para>detached</para></listitem>
|
|
|
|
<listitem><para>attached</para></listitem>
|
|
|
|
<listitem><para>attached-runtime</para></listitem>
|
|
|
|
<listitem><para>enabled</para></listitem>
|
|
|
|
<listitem><para>enabled-runtime</para></listitem>
|
|
|
|
<listitem><para>running</para></listitem>
|
|
|
|
<listitem><para>running-runtime</para></listitem>
|
|
</itemizedlist></para>
|
|
|
|
<para><function>AttachImage()</function> attaches a portable image to the system.
|
|
This method takes an image path or name, a list of strings that will be used to search for
|
|
unit files inside the image (partial or complete matches), a string indicating which
|
|
portable profile to use for the image (see <varname>Profiles</varname> property for
|
|
a list of available profiles), a boolean indicating whether to attach the image only
|
|
for the current boot session, and a string representing the preferred copy mode
|
|
(whether to copy the image or to just symlink it) with the following possible values:
|
|
<itemizedlist>
|
|
<listitem><para>(null)</para></listitem>
|
|
|
|
<listitem><para>copy</para></listitem>
|
|
|
|
<listitem><para>symlink</para></listitem>
|
|
</itemizedlist>
|
|
This method returns the list of changes applied to the system (for example, which unit was
|
|
added and is now available as a system service). Each change is represented as a triplet of
|
|
strings: the type of change applied, the path on which it was applied, and the source
|
|
(if any). The type of change applied will be one of the following possible values:
|
|
<itemizedlist>
|
|
<listitem><para>copy</para></listitem>
|
|
|
|
<listitem><para>symlink</para></listitem>
|
|
|
|
<listitem><para>write</para></listitem>
|
|
|
|
<listitem><para>mkdir</para></listitem>
|
|
</itemizedlist>
|
|
Note that an image cannot be attached if a unit that it contains is already present
|
|
on the system.</para>
|
|
|
|
<para><function>AttachImageWithExtensions()</function> attaches a portable image to the system.
|
|
This method is a superset of <function>AttachImage()</function> with the addition of
|
|
a list of extensions as input parameter, which will be overlaid on top of the main
|
|
image. When this method is used, detaching must be done by passing the same arguments via the
|
|
<function>DetachImageWithExtensions()</function> method. For more details on this functionality,
|
|
see the <varname>MountImages=</varname> entry on
|
|
<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
and <citerefentry><refentrytitle>systemd-sysext</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
|
|
The <varname>flag</varname> parameter is currently unused and reserved for future purposes.</para>
|
|
|
|
<para><function>DetachImage()</function> detaches a portable image from the system.
|
|
This method takes an image path or name, and a boolean indicating whether the image to
|
|
detach was attached only for the current boot session or persistently. This method
|
|
returns the list of changes applied to the system (for example, which unit was removed
|
|
and is no longer available as a system service). Each change is represented as a triplet of
|
|
strings: the type of change applied, the path on which it was applied, and the source
|
|
(if any). The type of change applied will be one of the following possible values:
|
|
<itemizedlist>
|
|
<listitem><para>unlink</para></listitem>
|
|
</itemizedlist>
|
|
Note that an image cannot be detached if a unit that it contains is running.</para>
|
|
|
|
<para><function>DetachImageWithExtensions()</function> detaches a portable image from the system.
|
|
This method is a superset of <function>DetachImage()</function> with the addition of
|
|
a list of extensions as input parameter, which were overlaid on top of the main
|
|
image via <function>AttachImageWithExtensions()</function>.
|
|
The <varname>flag</varname> parameter is currently unused and reserved for future purposes.</para>
|
|
|
|
<para><function>ReattachImage()</function> combines the effects of the
|
|
<function>AttachImage()</function> method and the <function>DetachImage()</function> method.
|
|
The difference is that it is allowed to reattach an image while one or more of its units
|
|
are running. The reattach operation will fail if no matching image is attached.
|
|
The input parameters match the <function>AttachImage()</function> method, and the return
|
|
parameters are the combination of the return parameters of the
|
|
<function>DetachImage()</function> method (first array, units that were removed) and the
|
|
<function>AttachImage()</function> method (second array, units that were updated or added).</para>
|
|
|
|
<para><function>ReattachImageWithExtensions()</function> reattaches a portable image to the system.
|
|
This method is a superset of <function>ReattachImage()</function> with the addition of
|
|
a list of extensions as input parameter, which will be overlaid on top of the main
|
|
image. For more details on this functionality, see the <varname>MountImages=</varname> entry on
|
|
<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
and <citerefentry><refentrytitle>systemd-sysext</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
|
|
The <varname>flag</varname> parameter is currently unused and reserved for future purposes</para>
|
|
|
|
<para><function>RemoveImage()</function> removes the image with the specified name.</para>
|
|
|
|
<para><function>MarkImageReadOnly()</function> toggles the read-only flag of an image.</para>
|
|
|
|
<para><function>SetPoolLimit()</function> sets an overall quota limit on the pool of images.</para>
|
|
|
|
<para><function>SetImageLimit()</function> sets a per-image quota limit.</para>
|
|
|
|
<para>The <function>AttachImageWithExtensions()</function>,
|
|
<function>DetachImageWithExtensions()</function> and
|
|
<function>ReattachImageWithExtensions()</function> methods take in options as flags instead of
|
|
booleans to allow for extendability, defined as follows:</para>

<title>Methods</title>

|
|
|
<para>The following methods implement the same operation as the respective methods on the
|
|
<interfacename>Manager</interfacename> object (see above). However, these methods operate on the image
|
|
object and hence does not take an image name parameter. Invoking the methods directly on the Manager
|
|
object has the advantage of not requiring a <function>GetImage()</function> call to get the image object
|
|
for a specific image name. Calling the methods on the Manager object is hence a round trip
|
|
optimization. List of methods:
