Kong : missing database for connect

im trying to set up Kong for my company, i followed the instruction from Kong documentation.

first i run this command:

docker network create kong-net

and then this command:

docker run -d --name kong-database \
               --network=kong-net \
               -p 5432:5432 \
               -e "POSTGRES_USER=kong" \
               -e "POSTGRES_DB=kong" \
               -e "POSTGRES_PASSWORD=kong" \
               postgres:9.6

according to documentation, next step is run the migration with this command

docker run --rm --network=kong-net -e "KONG_DATABASE=postgres" -e "KONG_PG_HOST=kong-database" -e "KONG_PG_USER=kong" -e "KONG_PG_PASSWORD=kong" kong:latest kong migrations up

but it keeps giving me this error

    -p 8443:8443 \
    -p 8001:8001 \

you can also use this docker-compose if you don't have any issue
