Getting started

This page contains instructions for software developers who want to get started with usage and development of the TMC Leaf Nodes.


Detailed information on how the SKA Software development community works is available at the SKA software developer portal. There you will find guidelines, policies, standards and a range of other documentation.

Set up your development environment

This project is structured to use k8s for development and testing so that the build environment, test environment and test results are all completely reproducible and are independent of host environment. It uses make to provide a consistent UI (run make help for targets documentation).

Install minikube

You will need to install minikube or equivalent k8s installation in order to set up your test environment. You can follow the instruction here: :: git clone cd deploy-minikube make all eval $(minikube docker-env)

Please note that the command `eval $(minikube docker-env)` will point your local docker client at the docker-in-docker for minikube. Use this only for building the docker image and another shell for other work.

How to Use

Clone this repo: :: git clone cd ska-tmc-cspleafnodes

Install dependencies :: apt update apt install -y curl git build-essential libboost-python-dev libtango-dev curl -sSL | python3 - source $HOME/.poetry/env

Please note that:
  • the libtango-dev will install an old version of the TANGO-controls framework (9.2.5);

  • the best way to get the framework is compiling it (instructions can be found here);

  • the above script has been tested with Ubuntu 20.04.

During this step, `libtango-dev` instalation can ask for the Tango Server IP:PORT. Just accept the default proposed value.

Install python requirements for linting and unit testing: :: $ poetry install

Activate the poetry environment: :: $ source $(poetry env info –path)/bin/activate

Follow the steps till installation of dependencies then run below command: :: $ virtualenv cn_venv $ source cn_venv/bin/activate $ make requirements

Run python-test: :: $ make python-test PyTango 9.3.3 (9, 3, 3) PyTango compiled with: Python : 3.8.5 Numpy : 0.0.0 ## output generated from a WSL windows machine Tango : 9.2.5 Boost : 1.71.0

PyTango runtime is: Python : 3.8.5 Numpy : None Tango : 9.2.5
