Tool for running ARTIQ in Docker container.
Project description
Dockerized ARTIQ
This repository provides tools to operate with ARTIQ in dockerized environment. It makes work with ARTIQ independent from external binary repositories.
What you get with the image is a full ARTIQ installation that can be
instantiated and used as a Docker container. dartiq
script acts as an
interface between you and Docker and makes use of dockerized ARTIQ
user-friendly.
Installing
DARTIQ scirpt is available on PyPI:
python3 -m pip install dartiq
Running an ARTIQ-enabled shell
For example, to get a shell with ARTIQ installed just type dartiq shell
.
This will drop you in the shell with your current working directory mounted as
/workspace
directory in the container. It can be overriden using --workspace
option.
Running single command
You can run a single command in Docker container by using run
option,
e.g. dartiq run "artiq_run ./experiment.py"
. Please note that your command
must be taken into quotes!
By default, inside the container, you'll act as user of uid
and gid
of your
own. It should prevent you from having permission problems. If you need to use
different uid
and gid
, use --user-group
option.
CAUTION: To be able to access USB devices inside the container,
/dev/bus/usb
is mounted and container is run in privileged mode
(You were warned!). This can be disabled by adding --without-usb
option.
Xilinx Vivado support
To be able to build ARTIQ firmware for Xilinx FPGAs, you'll need to have Xilinx
Vivado suite available inside the container.
If you source Xilinx Vivado settings64.sh
(you need to have Vivado installed
on your host system) prior to running dartiq
, a path under which Vivado is
installed will be mounted in the container and your Vivado installation will be
ready to use.
If you need provide license information to the Xilinx Vivado, you can pass an
appropriate information using either --copy-env-var XILINXD_LICENSE_FILE
option, which copies given variable to container environment, or by adding new
variable with --add-env-var XILINXD_LICENSE_FILE=<...>
.
External Python modules
It may happen that you want to add some Python module to be used inside the
container. Notably, a slightly modified version of ARTIQ, MiSoC or Migen may be
of your interest. You can do it with --add-module <MODULE PATH>
option.
This will mount your module in /modules
directory and add appropriate entry
in the PYTHONPATH
.
CAUTION: If you want to use ARTIQ as additional module, it is advised to use
commit used to build DARTIQ image as a base commit to avoid dependency problems.
You can always check ARTIQ commit used to build an image with dartiq version
command.
Mounting files to container
If, during run time, you need files or directories that are not beneath current
working directory (i.e. are not in your workspace), you can mount them using
-f
command line option. This will mount selected file/directory under
/mountpoints
inside the container. Additionally, in the container environment,
a variable will be created named after file/directory basename with dots
replaced with underscores and converted to uppercase. This variable will hold
path to the mounted directory.
Option syntax is -f <path to file/directory>[:alias]
. Alias is optional and
can be used to mount file/directory under different name. For example
-f /home/john/foo:bar.a
will mount /home/john/foo
under /mountpoints/bar.a
and add BAR_A=/mountpoints/bar.a
to the execution environment.
Obtaining information on ARTIQ version
dartiq version
can be used to get information on the source commit of DARTIQ
image, included ARTIQ commit and revision of Nix Scripts repository used to
build DARTIQ image.
Configuration file
It is possible to pass script configuration as a JSON file. This may be useful
for defining per-project configurations. By default dartiq.json
file from the
current directory is used. Configuration file path can be overridden using
--config
argument.
Example configuration file contents with all supported parameters:
{
"image": "technosystem/dartiq:latest",
"worksapce": "./",
"xilinx_vivado_path": null,
"xilinx_ise_path": null,
"with_usb": true,
"docker_options": [
"--privileged"
],
"python_modules": [
"modules/artiq",
"modules/misoc"
],
"verbose": false,
"copy_env_var": [
"XILINXD_LICENSE_FILE"
],
"add_env_var": [
"FOO=BAR"
]
}
Command-line options override configuration file settings or expand them in case of additional modules, Docker options and environment variables.
Device access from withing the container
By default container starts with USB support and in privileged mode. However,
because in the container you act as a normal user (of your current uid
),
appropriate udev
rules are required. The fact that you can access devices
without sudo
on your host system may not be enough for them to be accessible
for the user in the container as that user is not a member of additional groups
that may be available on your host (e.g. plugdev
).
To give unconstrained access to devices most commonly used with ARTIQ you can
create file /etc/udev/rules.d/99-dartiq.rules
(tested on Ubuntu 18.04 host)
with the following contents:
# FT232H Single HS USB-UART FIFO IC, aka Digilent HS-3 JTAG
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6014", MODE="666"
# FT4232H Quad HS USB-UART/FIFO IC, found on Kasli, Sayma, Metlino
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6011", MODE="666"
Examples of Use
# Display help message
dartiq --help
# Run experiment
dartiq run "artiq_run ./experiment.py"
# Display artiq_run help message
dartiq run "artiq_run --help"
# Running shell with ARTIQ from specified directory
dartiq shell -m ~/repos/artiq/artiq
