Development Setup

The complete build process requires 2 steps :

• a python module building step which will create a .whl file
• a docker image building step which will create a container image and install the previously built .whl file

build pip module

rm dist/*
python3 -m build .

install pip module locally

python3 -m venv .testenv
source .testenv/bin/activate
python3 -m pip install --no-cache-dir \
--index-url="https://artifacts.cloud.mov.ai/repository/pypi-experimental/simple" \
--extra-index-url https://pypi.org/simple \
./dist/*.whl

build docker images

For ROS noetic distribution :

docker build -t flow_initiator:noetic -f docker/noetic/Dockerfile .

Basic Run

For ROS noetic distribution :

docker run -t flow_initiator:noetic

You don't need to worry about the 4th digit, as the CI system does the automatic bump of it.

docker run -t flow_initiator:noetic

Development stack

For ROS noetic distribution :

sudo chmod 777 -Rf  tests/{logs,shared,userspace}
docker-compose -f tests/docker-compose.yml up --build -d

Cleaning :

docker-compose -f tests/docker-compose.yml down --remove-orphans --volumes
