psycopg2.operationalError: impossible de se connecter au serveur: aucun itinéraire à héberger est le serveur exécuté sur l'hôte "DB" et accepter les connexions TCP / IP sur le port

Après les instructions ici, c'était bien sur OpenSUSE Tumbleweed avec Docker version 20.10.6-CE, construction 8728DD246C3A

https://github.com/mirumee/saleor-platform#Chow-to-run-it

Mais sur OpenSuse Leap 15,3 avec Docker version 19.03.15, Build 99E3ED89195C La commande migrate (dernière commande) jette une erreur:

$ git clone https://github.com/mirumee/saleor-platform.git --recursive --jobs 3
$ cd saleor-platform
$ docker-compose build
$ docker-compose run --rm api python3 manage.py migrate

Erreur

psycopg2.operationalError: Impossible de se connecter au serveur: aucun itinéraire à héberger est le serveur exécutant sur l'hôte "DB" (172.21.0.4) et accepter les connexions TCP/IP sur le port 5432?

A essayé

Pourrait être dû aux paramètres du système d'exploitation. J'ai ajouté PortgreSQL Port 5432 aux ports publics par pare-feu, mais une erreur est toujours reçue.

A essayé

N'a pas fonctionné:

  • Redémarrer le service Docker
  • Redémarrer la machine

A essayé

Les commandes suivantes n'ont pas aidé:

https://stackoverflow.com/a/57502873/3405291

Obtenez Subnet (172.19.0.0/16) par:

docker network ls
docker inspect ${NETWORK_NAME}

Puis:

Sudo firewall-cmd --permanent --zone=public --add-rich-rule='rule family=ipv4 source address=172.19.0.0/16 accept'
Sudo firewall-cmd --reload
Sudo systemctl restart docker.service

A essayé

Cette approche n'a pas fonctionné, c'est-à-dire l'ajout de cela au service de base de données à l'intérieur docker-compose.yml déposer:

     environment:
       - POSTGRES_Host_AUTH_METHOD=trust
