When executing the demo project presented here the following problem might appear.

When trying to download spid-entities-idps.xml from https://registry.spid.gov.it/entities-idp, the registry.spid.gov.it service is often not available returning the following error which causes the application to crash e not be able to start successfully

Resolving registry.spid.gov.it (registry.spid.gov.it)... 93.147.186.172 Connecting to registry.spid.gov.it (registry.spid.gov.it)|93.147.186.172|:443... connected. HTTP request sent, awaiting response... 502 Bad Gateway ERROR 502: Bad Gateway.

A possible solution could be to update the example/entrypoint.sh as follows

wget https://registry.spid.gov.it/entities-idp -O metadata/idp/spid-entities-idps.xml status=$? while [ $status != 0 ]; do echo "Retrying download from registry.spid.gov.it..." wget https://registry.spid.gov.it/entities-idp -O metadata/idp/spid-entities-idps.xml status=$? done
