Thoth's Flask stack guidance example

Note

For a deeper look into details, please use s2i-example-tensorflow which is a maintained reference of Thoth's s2i example.

This is an example of OpenShift's s2i (source-to-image) application which uses Thoth's recommendations to recommend a Flask stack for a specific hardware where Flask application is supposed to be run together with software environment (base image).

The application is showing a generic approach and how to integrate inside OpenShift's s2i build process. To have recommendations suited for your specific hardware, you need to configure the build to be done on specific hardware where the application is supposed to be run (specific node placement for build and application run which should match).

Usage

To deploy this application to OpenShift:

oc project <YOUR-PROJECT-NAME>
oc process -f openshift.yaml | oc apply -f -

After applying the templates, the build should be started. As there is no Pipfile.lock provided, Thoth is contacted to give guidance for the deployed application. Computing recommendations for the application stack used in this application takes approximately 10 seconds - the time after which you get back recommendations varies based on the load and deployment you are contacting.

To remove this application from OpenShift:

oc delete all --selector 'app=s2i-example-flask'

Additional information

Please take a look at s2i-example-tensorflow which has additional info and documented configuration options. The s2i-example-tensorflow repo is also better maintained and kept up-to-date.
