I would recommend against using an Alpine based images. The benefits of using
an Alpine image are overrated and you actually loose a lot by using them as it
lacks tools you would need to debug your application when you have problems.
Running up a container and getting as interactive terminal in it, manually
installing packages, and then stopping it and committing it is also not a good
practice as it can't be automated and placed under version control.
For OpenShift what you want to research is the Source to Image (S2I) builders.
This allows you to put your application source code for your web application
into a Git repo, along with a requirements.txt file which lists what Python
packages that need to be installed. An S2I build can then be set up in
OpenShift which points to the repo and OpenShift will pull down the repo,
automatically install any packages listed in requirements.txt, and set up your
image so that when it is deployed, the web application is run.
An example of such a repo is:
https://github.com/OpenShiftDemos/os-sample-python
<https://github.com/OpenShiftDemos/os-sample-python>
To learn more about deploying applications to OpenShift, using S2I, I would
suggest you read:
https://www.openshift.com/for-developers/
<https://www.openshift.com/for-developers/>
https://www.openshift.com/deploying-to-openshift/
<https://www.openshift.com/deploying-to-openshift/>
Reading those will save you a lot of trial and error around working out how to
use OpenShift.
