Setup virtual environment

    pip install virtualenv
    virtualenv venv
    source venv/bin/activate
    pip install -r requirements.txt

Build and use docker for development (for macos dev for instance)

    # Increase base side with: 1) sudo dockerd --storage-opt dm.basesize=100G
    # 2) Changing DOCKER_OPTS ="--storage-opt dm.basesize=50G" in /etc/default/docker.
    # Or in UI: Docker > Settings > Resources > Advanced > Disk usage limit > Apply & Restart
    docker image prune -f && docker buildx prune -f && docker container prune -f && docker volume prune -af && docker system prune -af && docker builder prune -af
    gcloud auth login --update-adc
    docker buildx build --platform linux/amd64 -t europe-west1-docker.pkg.dev/remote-observatory-dev-jcy/remote-observatory-main-repo/remote_observatory:latest .

Build iso with packer

Installing packer

On mac:

    brew tap hashicorp/tap
    brew install hashicorp/tap/packer
    packer # you should see a list of Packer commands and options.
    brew install qemu

On ubuntu:

    wget -O - https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
    echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
    sudo apt update && sudo apt install packer
    packer # you should see a list of Packer commands and options
    # You might also have to run sudo chmod 666 /var/run/docker.sock after installing docker in utm for instance
    sudo apt install qemu-kvm qemu-system libvirt-daemon bridge-utils virt-manager virtinst libvirt-daemon-system

Build iso with packer

    # On ubuntu you might need to do echo '{ "experimental": true }' | sudo tee -a /etc/docker/daemon.json
    cd packer
	packer init -upgrade ./templates/ubuntu-template.pkr.hcl
	# You might want to make sure you have proper formatting with
	packer fmt .
	# You might also want to make sure your template is valid
	packer validate -var-file=./vars/ubuntu.pkrvars.hcl ./templates/ubuntu-template.pkr.hcl
	# Then build the filesystem only from docker image base, on mac, make sure docker is started with "open -a Docker"
    packer build -var-file=./vars/ubuntu.pkrvars.hcl -only="gen-fs-tarball.*" ./templates/ubuntu-template.pkr.hcl

Deploying iso - Commissioning docker composer

When running the iso for the first time, here are a few useful tips:

Grafana

user: admin pwod: admin

Mosquitto

  sudo apt-get install mosquitto-clients # brew install mosquitto
  mosquitto_sub -h 127.0.0.1 -p 1883 -t observatory/WEATHER
  mosquitto_pub -h localhost -p 1883 -t observatory/GUIDING --insecure -m '{"data": {"state": {"test": 0}}}'
  mosquitto_pub -h localhost -p 1883 -t observatory/WEATHER --insecure -m '{"data": {"state": "OK", "WEATHER_FORECAST": 0.5, "WEATHER_TEMPERATURE": 17.2, "WEATHER_WIND_SPEED": 10, "WEATHER_WIND_GUST": 5.9, "WEATHER_RAIN_HOUR": 1.5, "safe": "True"}}'

Building the nice reporting / latex reports

  sudo apt-get update
  sudo apt-get install -y texlive-latex-recommended texlive-publishers texlive-bibtex-extra texlive-science

Then build with

  python setup.py gen_report

Python requirements

pip install Cython setuptools wheel requests pyindi-client requests-cache watchdog astropy ntplib astroplan matplotlib tzwhere astroquery pymongo rawpy serial pyserial socket astroalign If you want to run the astrometry server locally, use: pip install django Pillow

Kafka GCN stuff

  sudo apt-get install libzstd-dev
  sudo apt-get install libz-dev
  sudo apt-get install rapidjson-dev
  sudo apt-get -y install libsasl2-dev
  sudo apt-get -y install libssl-dev
  git clone https://github.com/edenhill/librdkafka
  cd ./librdkafka
  git checkout v1.9.2-RC3
  ./configure && make -j8 && sudo make install && ldconfig
  pip install --no-binary :all: confluent-kafka

Arduino stuff

If you are interested in compiling/using the arduino stuff here, please download the official Arduino IDE, and define the following environment variable: $ARDUINO_SDK_PATH

  export ARDUINO_SDK_PATH="/opt/arduino-1.8.19/"
  cd Arduino
  mkdir build && cd build
  cmake ..
  make
  cd ..
  ./upload.sh

Setup indiweb on the machine that will host drivers

check installation information on: https://github.com/knro/indiwebmanager

pip install indiweb
sudo cp indiwebmanager.service /etc/systemd/system/
sudo chmod 644 /etc/systemd/system/indiwebmanager.service
sudo systemctl daemon-reload
sudo systemctl enable indiwebmanager.service

content of indiwebmanager.service

# From https://github.com/knro/indiwebmanager
# sudo pip install indiweb
# sudo cp indiwebmanager.service /etc/systemd/system/
# sudo chmod 644 /etc/systemd/system/indiwebmanager.service
# sudo systemctl daemon-reload
# sudo systemctl enable indiwebmanager.service
# sudo reboot
# sudo systemctl status indiwebmanager.service

Specific case of aarch64 kernel and armv8 userland

go to your set of build directories:

  • indi-altair
  • indi-duino
  • indi-libaltaircam
  • indi-toupbase
  • libmallincam
  • libstarshootg
  • indi
  • indi-asi
  • indi-gphoto
  • indi-shelyak
  • libASICamera2
  • libnncam
  • libtoupcam Then edit CMakeFiles/3.7.2/CMakeSystem.cmake replace aarch64 by armv8

How to launch the full stuff

First, if you have a custom configuration for your own setup, set the proper variable in you console:

export REMOTE_OBSERVATORY_CONFIG=backyard_config

If you want to try the software with simulators:

./apps/launch_indi_simu.sh
PYTHONPATH=. python ./apps/launch_remote_observatory.py

If, in addition you want the nice dashboard (might require additional dependencies, scripts are untested)

./apps/launch_PAWS.sh

Legacy or optional features

Support for DBus scripting ()

sudo apt-get install libgirepository1.0-dev gobject-introspection pip install PyGObject or conda install -c conda-forge pygobject

Support for the Dash dashboard (legacy, not used anymore):

pip install dash dash-core-components dash-html-components dash-renderer plotly

Web service (legacy, not used anymore)

For now, RemoteObservatory uses some web service to acquire data, so ensure that you have a json file containing the key for each API in your home directory:

  • For WUG, get your key here and store it in your home directory inside a .wug.json file
  • For nova (astrometry.net), get your key at here and store it in your home directory inside a .nova.json file

Arduino capture

PYTHONPATH=. python3 ./apps/launch_arduino_capture.py

TODO: WORK IN PROGRESS: Check before calling this a production software

  • make sure we are correctly scoring all constraints (not only binary values) in ObservationPlanner/Scheduler
  • Correct the stub inside of launch_remote_observatory that returns safe even if not safe
  • re-integrate the simulator mode that returns fine, even if not fine
  • Make a proper integration between our IndiMount and abstractMount inside of IndiAbstractMount, because right now it is a mess
  • Setup a calibrating_flat and calibrating_dark states
  • fill-in the class Calibration that mirrors the observation class and make sure that a new calibration is issued whenever an observation has completed (This should arise in Manager ?)
  • Check why the SITELONG entry in outputed file is wrong
  • ObservationPlanner/Scheduler l232 you NEED to setup proper FixedTarget.from_name
  • Observatory l76: uncomment the raise ScopeControllerError(msg)
  • Gast is important: Service/NTPTimeService.py l 137
  • Urgent: fix the hardcoded values in solve-field scripting
  • Urgent fix the max_pointing_error in pointing. Current one might be too low
  • L292 in StateMachine, find a better way to signal the issue when transitionning
  • Remove temporary fix in Scheduler: target = FixedTarget(SkyCoord(ra=1u.deg, dec=89u.deg)
  • Need to try to kill PHD2 while guiding and check that we return to parking state
  • Need to simulate a PHD2 star lost and check that we return to parking state
  • The loop_mode in GuiderPHD2 is ambiguous (let it like this for now)
  • Check all states from the state machine, and make sure they often call model.check_messages()
  • If an observation is split into multiple observing block, shouldn't they have the same id ? that would allow to skip pointing when going from one block to another
  • check if we actually refocus in case the observation id is the same
  • the publisher_port parameter in weather config should be refactored with messaging parameter
  • PHD2 is not closed properly / two instance might be launched which cause error
  • Transform the Manager.acquire_calibration into a generator, so that every acquisition is yielded toward the State, and it may issue messages in the meantime
  • AbstractCamera (and potentially other classes based on BASE) have its self.config attribute overwritten somewhere ? it evaluates to None at some point, so it needs investigation
  • indiclient parser and PHD2 client parser are almost the same... You need to abstract away the XML client part and make a single class for this

Helper

  • use find . -path ./venv -prune -o -name '*.py' to search stuf not in venv
  • use find . -path ./venv -prune -o -name '*.py' -exec grep -H string_to_find {} ;
  • use find . -path ./venv -prune -o -name '*.py' -exec sed -i -e 's/get_local_time_from_ntp/get_local_time/g' {} ; to replace stuff
