Quick Start Guide
Install Shrinkwrap
Packages don’t yet exist, so currently the only way to install Shrinkwrap is to install its dependencies and clone the git repository.
Shrinkwrap is tested on Ubuntu 20.04 although other Linux distributions are likely to JustWork (TM). macOS is also known to work when using the docker runtime as long as Docker Desktop has first been installed.
Shrinkwrap requires at least Python 3.6.9. Older versions may work, but are not tested.
sudo apt-get install git netcat-openbsd python3 python3-pip telnet
sudo pip3 install pyyaml termcolor tuxmake
git clone https://git.gitlab.arm.com/tooling/shrinkwrap.git
export PATH=$PWD/shrinkwrap/shrinkwrap:$PATH
If using a Python version older than 3.9, you will also need to install the
graphlib-backport pip package:
sudo pip3 install graphlib-backport
If using Docker Runtime Backend
If Docker was not previously set up on your system, you will need to install the package, create a ‘docker’ group and add your user to it. This allows shrinkwrap to interact with docker without needing sudo. For more information see docker linux-postinstall.
sudo apt-get install docker.io
sudo groupadd docker
sudo usermod -aG docker $USER
# Log out/log in for change to take effect
If using Podman Runtime Backend
Note
Podman is only available within Ubuntu repositories from Ubuntu 20.10 and newer. See podman installation instructions for installation methods for other distributions.
sudo apt-get install podman
Optional Environment Variables
Shrinkwrap consumes the following set of optional environment variables:
name |
default |
description |
|---|---|---|
SHRINKWRAP_CONFIG |
<None> |
Colon-separated list of paths to config stores. Configs are searched for relative to the current directory as well as relative to these paths. |
SHRINKWRAP_BUILD |
~/.shrinkwrap/build |
Location where config builds are performed. Each config has its own subdirectory, with further subdirectories for each of its components. |
SHRINKWRAP_PACKAGE |
~/.shrinkwrap/package |
Location where config builds are packaged to. When running a config, it is done from the package location. |
Guided Tour: Configure a platform and boot a kernel
This section provides a guided tour of Shrinkwrap, using a common use case of building required platform FW and configuring the FVP for Armv9.3 and booting a kernel. This example uses EDK2 (UEFI) but many other options are available.
Note
By default, the below commands will use the docker runtime and automatically
download and use the appropriate container image from Docker Hub.
Alternatively, you can choose to run with the null runtime by providing
--runtime=null (between shrinkwrap and the sub-command). This will
cause all commands to be executed on the native system. Users are responsible
for setting up the environment in this case. Or if you have chosen to use
Podman as the runtime backend, add --runtime=podman.
First invoke the tool to view help:
shrinkwrap --help
shrinkwrap <command> --help
Now, inspect the available configs:
shrinkwrap inspect
This will show all of the (concrete) configs in the config store. The below
output shows a sample. Notice that each config lists its runtime variables
(“rtvars”) along with their default values. None means there is no default
and the user must provide a value when running the config. (A “concrete” config
is one that is deemed ready-to-use out-of-the-box. Whereas a config “fragment”
is a piece of config that is usually composed with others and configured into a
concrete config. You can view non-concrete fragments by providing extra args).

name: bootwrapper.yaml
description: Best choice for: I have a linux-system.axf boot-wrapper and
want to run it.
This config does not build any components (although
shrinkwrap still requires you to build it before running).
Instead the user is expected to provide a boot-wrapper
executable (usually called linux-system.axf) as the
BOOTWRAPPER rtvar, which will be executed in the FVP. A
ROOTFS can be optionally provided. If present it is loaded
into the virtio block device (/dev/vda).

name: ns-edk2.yaml
description: Best choice for: I want to run Linux on FVP, booting with
ACPI/DT, and have easy control over its command line.
Brings together TF-A and EDK2 to provide a simple non-
secure world environment running on FVP. Allows easy
specification of the kernel image and command line, and
rootfs at runtime (see rtvars). ACPI is provided by UEFI.
An extra rtvar is added (DTB) which allows specification of
a custom device tree. By default (if not overriding the
rtvar), the upstream kernel device tree is used. DT is
enabled by default. Use 'acpi=force' to enable ACPI boot.
By default (if not overriding the rtvars) a sensible
command line is used that will set up the console for
logging and attempt to mount the rootfs image from the
FVP's virtio block device. However the default rootfs image
is empty, so the kernel will panic when attempting to
mount; the user must supply a rootfs if it is required that
the kernel completes its boot. No default kernel image is
supplied and the config will refuse to run unless it is
explicitly specified.
Note that by default, UEFI variables are build time
configured directing EDK2 to boot to the shell. This will
cause startup.nsh to be executed and will start the kernel
boot. This way everything is automatic. By default, all
EDK2 output is muxed to stdout. If you prefer booting UEFI
to its UI, override the the build pcd parameter
`PcdUefiShellDefaultBootEnable` using the overlay and
override terminals 'bp.terminal_0'.type to 'telnet'.

name: ns-preload.yaml
description: Best choice for: I just want to run Linux on FVP.
A simple, non-secure-only configuration where all
components are preloaded into memory (TF-A's BL31, DTB and
kernel). The system resets directly to BL31. Allows easy
specification of a custom command line at build-time (via
build.dt.params dictionary) and specification of the device
tree, kernel image and rootfs at run-time (see rtvars).
By default (if not overriding the rtvars), the upstream
kernel device tree is used along with a sensible command
line that will set up the console for logging and attempt
to mount the rootfs image from the FVP's virtio block
device. However the default rootfs image is empty, so the
kernel will panic when attempting to mount; the user must
supply a rootfs if it is required that the kernel completes
its boot. No default kernel image is supplied and the
config will refuse to run unless it is explicitly
specified. Note: If specifying a custom dtb at runtime,
this will also override any command line specified at build
time, since the command line is added to the chosen node of
the default dtb.

Now build the ns-edk2.yaml config. This allows booting a kernel on FVP,
using edk2 as the bootloader (it uses DT by default, but can be made to use ACPI
by passing acpi=force at runtime). (optionally add --verbose to see all
the output from the component build systems).
shrinkwrap build --overlay=arch/v9.3.yaml ns-edk2.yaml
This will sync all the required repos, build the components and package the artifacts.
Warning
By default, Shrinkwrap will sync all component repos to the revision specified
in the config on every build invocation. If you have made changes in the
working directory, shrinkwrap refuses to sync and displays an error. You can
override this behaviour so that Shrinkwrap just builds whatever is in the
working directory by adding --no-sync <component> or --no-sync-all to
the command line. Alternatively you can force shrinkwrap to override your
changes by adding --force-sync <component> or --force-sync-all to the
command line.
Alternatively, pass --dry-run to view the shell script that would have been
run:
shrinkwrap build --overlay=arch/v9.3.yaml --dry-run ns-edk2.yaml

Now start the FVP. We will pass our own kernel and rootfs disk image as runtime
variables. A config can define any number of runtime variables which may have
default values (see inspect command above). If a variable has no default
value, then the user must provide a value when invoking the run command. The
ns-edk2.yaml config requires the user to provide a kernel, but the rootfs
is optional. If the rootfs was omitted, the kernel would boot to the point where
it attempts to mount the rootfs then panic (which is sufficient for some
development use cases!).
shrinkwrap run --rtvar=KERNEL=path/to/Image --rtvar=ROOTFS=path/to/rootfs.img ns-edk2.yaml
This starts the FVP and multiplexes all the UART terminals to stdout and
forwards stdin to the tfa+linux uart terminal. This allows the user to
interact directly with the FVP in a terminal without the need for a GUI setup:

Overlays are an important concept for Shrinkwrap. An overlay is a config fragment (either a yaml file or a json-encoded string) that can be passed separately on the command line and forms the top layer of the config. In this way, it can override or add any required configuration. You could achieve the same effect by creating a new config and specifying the main config as a layer in that new config, but with an overlay, you can apply a config fragment to many different existing configs without the need to write a new config file each time. You can see overlays being using in the above commands to target a specific Arm architecture revision (v9.3 in the example). You can change the targeted architecture just by changing the overlay. There are many other places where overlays come in handy. See Shrinkwrap Recipes for more examples.
You will notice in the examples above, that only build commands include the
overlay and run commands don’t specify it. This is because the final config
used for building is packaged in the built package, so when running the package,
the presence of the overlay is implicit. However, a user could choose to provide
an extra overlay at run time, that affects only the runtime portion to
customize even further if desired.
For debug purposes, you can see a final, merged config by using the process
command:
shrinkwrap process --action=merge --overlay=arch/v9.3.yaml ns-edk2.yaml

description: "Best choice for: I want to run Linux on FVP, booting with ACPI/DT, and\
\ have easy control over its command line.\nBrings together TF-A and EDK2 to provide\
\ a simple non-secure world environment running on FVP. Allows easy specification\
\ of the kernel image and command line, and rootfs at runtime (see rtvars). ACPI\
\ is provided by UEFI.\nAn extra rtvar is added (DTB) which allows specification\
\ of a custom device tree. By default (if not overriding the rtvar), the upstream\
\ kernel device tree is used. DT is enabled by default. Use 'acpi=force' to enable\
\ ACPI boot.\nBy default (if not overriding the rtvars) a sensible command line\
\ is used that will set up the console for logging and attempt to mount the rootfs\
\ image from the FVP's virtio block device. However the default rootfs image is\
\ empty, so the kernel will panic when attempting to mount; the user must supply\
\ a rootfs if it is required that the kernel completes its boot. No default kernel\
\ image is supplied and the config will refuse to run unless it is explicitly specified.\n\
Note that by default, UEFI variables are build time configured directing EDK2 to\
\ boot to the shell. This will cause startup.nsh to be executed and will start the\
\ kernel boot. This way everything is automatic. By default, all EDK2 output is\
\ muxed to stdout. If you prefer booting UEFI to its UI, override the the build\
\ pcd parameter `PcdUefiShellDefaultBootEnable` using the overlay and override terminals\
\ 'bp.terminal_0'.type to 'telnet'.\nWhen booting with device tree, a directory\
\ can optionally be shared from the host system into the Linux environment running\
\ in the FVP. To do so, set the SHARE rtvar to the desired directory, then mount\
\ the share inside the FVP with the following (or automate it in fstab):\n.. code-block::\
\ shell\n # mkdir /share\n # mount -t 9p -o trans=virtio,version=9p2000.L FM /share"
