Sequelize not work in docker (Node + Postgres) - postgresql

Question

Even with containers connected to the same network, when executing the migration on sequelize, the error 'getaddrinfo ENOTFOUND' is returned.
If I remove the host address in the 'database.js' settings, the migration runs but the CRUD routines stop running returning the error "connect ECONNREFUSED 127.0.0.1:5432"
If I point to the 'postgresdb' container in the 'database.js' settings, the CRUD routines execute but the sequelize migration does not.
Help me please
