As @Elpis wrote in the comments section, he followed this guide to install Apache Airflow on Kubernetes.

And he solved the problem by adding extraVolumeMounts and extraVolumes to the worker pod, and also to the web pod and to the scheduler pod.

extraVolumeMounts:
  - name: requirements
    mountPath: /bitnami/python/

## Add extra volumes
extraVolumes:
  - name: requirements
    configMap:
# Provide the name of the ConfigMap containing the files you want
# to add to the container
      name: requirements

After that, all extra Python packages were installed.
