Here is the docker compose:
Copy code
version: '3.1'

services:
  supertoken-users:
    image: registry.supertokens.io/supertokens/supertokens-postgresql
    ports:
      - '3567:3567'
    environment:
      - POSTGRESQL_USER=root
      - POSTGRESQL_PASSWORD=example
      - POSTGRESQL_HOST=host
      - POSTGRESQL_PORT=5432
      - POSTGRESQL_DATABASE_NAME=authdb

  db:
    image: postgres
    restart: always
    ports:
      - '5432:5432'
    environment:
      POSTGRES_USER: root
      POSTGRES_PASSWORD: example
      POSTGRES_DB: authdb

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080
r
POSTGRESQL_HOST
should be 
db
? Cause the name of the db in the compose file is 
db
c
wait so host is not a 
url
but a 
docker container
itself?
so the supertoken container is trying to connect to a postgres container named db
r
Well. it's the the address on which the db is reachable
c
ok I thought it was the address
r
It is the address of the postgresql container
c
makes sense
r
but in docker network, that is = to the name of the service
which i think in this case is 
db
c
ok, I thought you have to input the url of the database
but this makes developing a lot easier
r
im not sure what you mean by url of database and how that's different from the address on which the db is hosted at
c
ah
by that I meant localhost
r
hmm
