Set up local environment

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Get subjects for books from Annif

time python get-annif-subjects.py

Local development

Set up Elasticsearch and indices

docker run --rm --net elastic --name es-node01 -p 9200:9200 -p 9300:9300 -e "xpack.security.enabled=false" -e "discovery.type=single-node" -v es-data:/usr/share/elasticsearch/data docker.elastic.co/elasticsearch/elasticsearch:8.9.1

# curl -X DELETE "localhost:9200/books"  # Delete existing index
time python import-books-to-es.py &> import-books.out  # Takes 5 min for 1000 books, 15 min for 4000 books, etc.

# curl -X DELETE "localhost:9200/autocomplete"  # Delete existing index
python create-autocomplete-index.py

Alternatively use Elasticsearch running in OpenShift

export ELASTICSEARCH_URL=https://kvp-2023-workshop-elasticsearch.apps.kk-test.k8s.it.helsinki.fi:443

Start application

flask run --debug
# gunicorn app:app  # Alternatively use gunicorn

Deploy in OpenShift

The application will be publicly available at the address given in route template.

If this repository is private a deploykey needs to be in place as a secret in Openshift.
