On first time run, the migration and seeding will not be running since no database is created. So run again the same command. Sometime sequelize won't create database, in that case, manually create a database with whatever name you given in .env file. Follow these:

docker ps

This will list all the containers, from these copy the id of postgres, then

docker exec -it <POSTGRES_CONTAINER_ID> sh

This will connect to postgres container and open up sh.

psql -U <USER>
