(Python) Process and File Controller
Project description
Overview
This repository provides pfcon – a controlling service that speaks to remote pman and pfioh services. This is the bleeding edge branch.
pfcon
Most simply, pfcon pushes local data to a remote location (by talking to a remote pfioh service), runs some process on this data in the remote space using pman, and then copies the resultant data back to a local target space.
It can be used to query and control the following (for example):
state: Is job <XYZ> still running?
result: What is the stdout (or stderr) from job <XYZ>?
control: Kill job <XYZ>
Installation
Installation is relatively straightforward, and we recommend using either python virtual environments or docker.
Python Virtual Environment
On Ubuntu, install the Python virtual environment creator
sudo apt install virtualenv
Then, create a directory for your virtual environments e.g.:
mkdir ~/python-envs
You might want to add to your .bashrc file these two lines:
export WORKON_HOME=~/python-envs
source /usr/local/bin/virtualenvwrapper.sh
Then you can source your .bashrc and create a new Python3 virtual environment:
source .bashrc
mkvirtualenv --python=python3 python_env
To activate or “enter” the virtual env:
workon python_env
To deactivate virtual env:
deactivate
Using the fnndsc/ubuntu-python3 dock
We provide a slim docker image with python3 based off Ubuntu. If you want to play inside this dock and install pman manually, do
docker pull fnndsc/ubuntu-python3
This docker has an entry point python3. To enter the dock at a different entry and install your own stuff:
docker run -ti --entrypoint /bin/bash fnndsc/ubuntu-python3
Now, install pman and friends using pip
apt update && \
apt install -y libssl-dev libcurl4-openssl-dev librtmp-dev && \
pip install pfcon
If you do the above, remember to commit your changes to the docker image otherwise they’ll be lost when you remove the dock instance!
docker commit <container-ID> local/ubuntu-python3-pfcon
where ``<container-ID>`` is the ID of the above container.
Using the fnndsc/pfcon dock
The easiest option however, is to just use the fnndsc/pfcon dock.
docker pull fnndsc/pfcon
and then run
docker run --name pfcon -v /home:/Users --rm -ti fnndsc/pfcon --forever --httpResponse
