docker alpine postgres組成不執行docker-entrypoint-initdb.d腳本

Question

在docker compose中使用https://github.com/kiasaki/docker-alpine-postgres圖像時，當我從日誌中查看時，/docker-entrypoint.initdb.d中的腳本未被執行：

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 

的事情是，如果我建Dockerfile獨立和運行容器，它將執行文件夾內的SQL文件，比如你可以從日誌中看到：

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 
.LOG: aborting any active transactions 
LOG: autovacuum launcher shutting down 
LOG: shutting down 
LOG: database system is shut down 
done 
server stopped 
LOG: database system was shut down at 2016-09-05 18:28:21 UTC 
LOG: MultiXact member wraparound protections are now enabled 
LOG: database system is ready to accept connections 
LOG: autovacuum launcher started 
LOG: received fast shutdown request 
LOG: aborting any active transactions 
LOG: autovacuum launcher shutting down 
LOG: shutting down 
LOG: database system is shut down 

泊塢窗，撰寫.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 

我在這裏做錯了什麼？

UPDATED因爲他使用自己的Dockerfile，而不是從github鏈接。

您能否推測碼頭運行命令，以便if I build the Dockerfile standalone and run the container, it will execute the sql files inside the folder。您應該將某個目錄掛載到容器，以便它可以找到SQL文件。

我在https://github.com/kiasaki/docker-alpine-postgres/blob/master/Dockerfile處讀取Dockerfile並問自己SQL文件在哪裏？它只是使目錄，而不復制SQL文件

mkdir /docker-entrypoint-initdb.d 

然後，在docker-entrypoint.sh，它檢查是否有任何SQL文件來執行

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 

我認爲我們應該安裝一個SQL目錄，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
