Docker compose missing python package

Asked 2022-Mar-11 at 08:12

To preface I'm fairly new to Docker, Airflow & Stackoverflow.

I've got an instance of Airflow running in Docker on an Ubuntu (20.04.3) VM.

I'm trying to get Openpyxl installed on build in order to use it as the engine for pd.read_excel.

Here's the Dockerfile with the install command:

ANSWER

Answered 2022-Mar-03 at 15:56

We've had some problems with Airflow in Docker so we're trying to move away from it at the moment.

Some suggestions:

Set the version of openpyxl to a specific version in requirements.txt
Add openpyxl twice to requirements.txt
Create a requirements.in file with your main components, and create a requirements.txt off that using pip-compile. This will add subcomponents too
Try specifying a python version as well

Hopefully one of these steps will help.

SQL tables have no order. Without an explicit ORDER BY in the SELECT statement, you are not even guaranteed the same order between two consecutive SELECT:s.

pymongo [SSL: CERTIFICATE_VERIFY_FAILED]: certificate has expired on Mongo Atlas

ANSWER

Answered 2021-Oct-03 at 05:57

This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.

The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/

Django - Full test suite failing when adding a TestCase, but full test suite passes when it is commented out. All TestCase pass when run individually

Asked 2021-Dec-23 at 10:31

So this seems to be an issue talked about here and there on StackOverflow with no real solution. So I have a bunch of tests that all pass when run individual. They even pass when run as a full test suite, EXCEPT when I add in my TestCase ExploreFeedTest. Now ExploreFeedTest passes when run by itself and it actually doesn't fail when run in the full test suite as in running python manage.py test, it causes another test HomeTest to fail, which passes on it's own and passes when ExploreFeedTest is commented out from the init.py under the test folder. I hear this is an issue with Django not cleaning up data properly? All my TestCase classes are from django.test.TestCase, because apparently if you don't use that class Django doesn't teardown the data properly, so I don't really know how to solve this. I'm also running Django 3.2.9, which is supposedly the latest. Anyone have a solution for this?

What is the reason of my error?

Did you read my previous answer to a similar question of yours? The last part warns about certain combinations of Alpine + Python and this seems to be happening right now.

I tried to replace psycopg2 with psycopg2-binary but have the same error

The problem here might be a python library that has dependencies on gcc, which is not shipped on alpine by default.

Try replacing this:
