Deployment (git push resin master) hangs in Running state


#1

Hi,

I’ve been having issues deploying my app. The last two releases I’ve tried to deploy have been stuck during git push resin master:

Any ideas on how to resolve this issue?


#4

Hi @smomni, when you do the push, what does it says, Building on <machine>, what’s the machine that you get, when it hangs?


#6

Hi @imrehg, it says Building on arm01 .


#7

Thanks, we are checking with the team and keep you posted.


#8

@smomni can you also paste the contents of requirements.txt here too?


#9

@imrehg requirements.txt:

atomicwrites==1.1.5
attrs==18.1.0
colorama==0.3.9
more-itertools==4.2.0
pluggy==0.7.1
psycopg2==2.7.5
py==1.5.4
pytest==3.7.1
ruamel.yaml==0.15.44
six==1.11.0
SQLAlchemy==1.2.10

#10

Hey, also what’s in the .[prod] folder? It looks like something from that folder is being installed and it goes into an infinite loop. Was that same pip install -e step working if you have tried on your local development machine, whether the module/code in there can be installed successfully?

The best would be if you could share the whole project (if it’s up on Github for example), but if not, this above is our current lead in troubleshooting the hang.


#11

pip install -e .[prod] installs the production variant of the python package by executing setup.py. Installation works locally on x86 architecture but fails on emulated ARM architecture (see cross-build directives in Dockerfile). Unfortunately, I’m unable to share the project as it is not open source (at least yet).

setup.py:

from setuptools import setup, find_packages
from connectivity import __version__

setup(
    name='connectivity',
    version=__version__,
    packages=find_packages(),
    extras_require={
        'dev': [],
        'test': ['pytest', 'pytest-cov'],
        'prod': ['RPi.GPIO==0.6.3']
    },
    entry_points={
        'console_scripts': [],
    },
)

#12

So that basically means, that the extra package of RPi.GPIO==0.6.3 is attempted to be installed?


#13

Yes, exactly.


#14

Does that hang happen all the time?

I’ve tried it a couple of times with a basic test project based on the code you pasted here, and that seems to work fine. Cutting to the relevant part:

I wonder why in your log it says [main] Processing /

One thing I would try. Add a working directory, and have the code there, instead of in / directly. Might be that some file system traversion happens.

So add:

WORKDIR /usr/src/app

for example, and have the COPY step after this setting. Then the local directory is assumed to be whatever you set in WORKDIR. This is just a hunch, not sure what other difference you might have compared to my test setup…


#15

No, there were several successful deployments before this.

Now I managed to get the deployment working! I moved a conditional import statement from connectivity/__init__.py to module connectivity/listener.py. However, the same import statement was fine in the previous successful deployment (75f237582f5d35c8eeba8e68c51dfe2001f89f1f) so I’m not exactly sure why it failed now ¯_(ツ)_/¯

Thanks for the help!


#16

Thanks for the feedback. Glad it works now, and just let us know if anything else comes up!
