package-installs
================
The package-installs element allows for a declarative method of installing and
uninstalling packages for an image build. This is done by creating a
package-installs.yaml or package-installs.json file in the element directory.
In order to work on Gentoo hosts you will need to manually install
`dev-python/pyyaml`.
example ``package-installs.yaml``
.. code-block:: YAML
libxml2:
grub2:
phase: pre-install.d
networkmanager:
uninstall: True
os-collect-config:
installtype: source
linux-image-amd64:
arch: amd64
dmidecode:
not-arch: ppc64, ppc64le
lshw:
arch: ppc64, ppc64le
python-dev:
dib_python_version: 2
python3-dev:
dib_python_version: 3
example package-installs.json
.. code-block:: json
{
"libxml2": null,
"grub2": {"phase": "pre-install.d"},
"networkmanager": {"uninstall": true}
"os-collect-config": {"installtype": "source"}
}
Setting phase, uninstall, or installtype properties for a package overrides
the following default values::
phase: install.d
uninstall: False
installtype: * (Install package for all installtypes)
arch: * (Install package for all architectures)
dib_python_version: (2 or 3 depending on DIB_PYTHON_VERSION, see dib-python)
Setting the installtype property causes the package only to be installed if
the specified installtype would be used for the element. See the
diskimage-builder docs for more information on installtypes.
The ``arch`` property is a comma-separated list of architectures to
install for. The ``not-arch`` is a comma-separated list of
architectures the package should be excluded from. Either ``arch`` or
``not-arch`` can be given for one package - not both. See
documentation about the ARCH variable for more information.
DEPRECATED: Adding a file under your elements pre-install.d, install.d, or
post-install.d directories called package-installs-<element-name> will cause
the list of packages in that file to be installed at the beginning of the
respective phase. If the package name in the file starts with a "-", then
that package will be removed at the end of the install.d phase.
Using post-install.d for cleanup
================================
Package removal is done in post-install.d at level 95. If you a
running cleanup functions before this, you need to be careful not
to clean out any temporary files relied upon by this element.
For this reason, generally post-install cleanup functions should
occupy the higher levels between 96 and 99.
