Docker alpine postgres in compose不执行Docker语言 - entrypoint-initd

Question

当在docker compose中使用https://github.com/kiasaki/docker-alpine-postgres映像时，/docker-entrypoint.initdb中的脚本。

 db_1   | LOG:  database system was shut down at 2016-09-05 18:16:02 UTC
 db_1   | LOG:  MultiXact member wraparound protections are now enabled
 db_1   | LOG:  database system is ready to accept connections
 db_1   | LOG:  autovacuum launcher started

问题是，如果我独立构建Dockerfile并运行容器，它将执行文件夹内的sql文件，就像你从日志中看到的那样:

waiting for server to start....LOG:  database system was shut down at 2016-09-05 18:28:18 UTC
LOG:  MultiXact member wraparound protections are now enabled
LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started
 done
server started
/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/syna-setup.sql
CREATE TABLE
INSERT 0 1
CREATE TABLE
waiting for server to shut down...LOG:  received fast shutdown request

docker-compose.yml:

version: '2'
services:
  db:
    build: ./db
    environment:
     - POSTGRES_PASSWORD=testpass
    restart: always
  app:
    build: ./app
    ports:
     - "5000:5000"
    volumes:
     - .:/app/src
    depends_on:
     - db
    environment:
     - DB_SERVER=postgres://postgres:testpass@db:5432/postgres

我在这里做错了什么?

更新 ，因为他使用自己的Dockerfile，而不是从github链接。

能否提供docker run命令，以便if I build the Dockerfile standalone and run the container, it will execute the sql files inside the folder。您应该将某个目录挂载到容器中，以便它可以找到SQL文件。

我在https://github.com/kiasaki/docker-alpine-postgres/blob/master/Dockerfile读Dockerfile，问自己SQL文件在哪里?它只创建目录而不复制SQL文件

mkdir /docker-entrypoint-initdb.d

然后，在docker-entrypoint.sh中，检查是否有SQL文件要执行

for f in /docker-entrypoint-initdb.d/*; do
        case "$f" in
            *.sh)  echo "$0: running $f"; . "$f" ;;
            *.sql) echo "$0: running $f"; psql --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" < "$f" && echo ;;
            *)     echo "$0: ignoring $f" ;;
        esac
        echo
done

我认为我们应该挂载一个SQL目录，比如

version: '2'
services:
  db:
    build: ./db
    environment:
     - POSTGRES_PASSWORD=testpass
    restart: always
    entrypoint:
     - docker-entrypoint.sh
    volumes:
     - ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
     - ./docker-entrypoint.sh:/docker-entrypoint.sh
