Question

运行docker-compose -f production.yml up最终会返回：

postgres_1      |   Connection matched pg_hba.conf line 95: "host all all all md5"
django_1        | PostgreSQL is unavailable (sleeping)...
postgres_1      | 2018-03-21 07:48:35.575 UTC [120] FATAL:  password authentication failed for user "DbUsErName"
postgres_1      | 2018-03-21 07:48:35.575 UTC [120] DETAIL:  Password does not match for user "DbUsErName".

在我的.envs / .production / .postgres中，我的envs以这种方式布局：

# PostgreSQL
# ------------------------------------------------------------------------------
POSTGRES_DB=luup
POSTGRES_USER=DbUsErName
POSTGRES_PASSWORD=myVeryYLongPW

在上述错误之前，终端也会输出：

celeryworker_1  | /entrypoint.sh: line 13: POSTGRES_USER: parameter not set

然而，它确实出现在compose / production / django / entrypoint.sh中的此文件中设置：

set -o errexit
set -o pipefail
set -o nounset


cmd="$@"

if [ -z "${POSTGRES_USER}" ]; then
    # the official postgres image uses 'postgres' as default user if not set explictly.
    export POSTGRES_USER=postgres
fi
export DATABASE_URL="postgres://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}"

自从我开始这个项目以来，我没有触及过很多postgres配置，因为这只是试图让它在Heroku上运行起来。所以我没有进入psql。

启动和运行该怎么办？

  celeryworker:

    command: /start-celeryworker.sh

  celerybeat:

Postgres容器在第一次运行时从env变量创建用户。因此，为了使用新值（生产用户名和密码），您可能需要重建它。

docker-compose stop postgres
docker-compose rm postgres
docker-compose -f production.yml up

Docker-compose up无法验证postgres用户
