Docker postgress用户“ postgres”未分配密码

Question

I keep getting

User "postgres" has no password assigned.

updated

.env

POSTGRES_PORT=5432
POSTGRES_DB=demo_db2
POSTGRES_USER=postgres
POSTGRES_PASSWORD=password

Even though the postgres password is set.

I'm trying to use the same variables from the following command

docker run --name demo4 -e POSTGRES_PASSWORD=password -d postgres

Could this be an issue with volumes ? im very confused.

I ran this command as well

 docker run -it --rm --name demo4 -p 5432:5432 -e POSTGRES_PASSWORD=password -e POSTGRES_USER=postgress postgres:9.4

You are missing the inclusion of the .env file...

Docker composer:

database:
  environment:
    - ENV_VAR=VALUE

or

database:
  env_file:
    - .env

Plain Docker:

docker run options --env ENV_VAR=VALUE ...

or

docker run options --env-file .env ...`
