Question

在docker compose中使用https://github.com/kiasaki/docker-alpine-postgres图像时，我从日志中查看时，/ docker-entrypoint.initdb.d中的脚本没有被执行：

 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

问题是，如果我独立构建Dockerfile并运行容器，它将执行文件夹中的sql文件，就像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
.LOG:  aborting any active transactions
LOG:  autovacuum launcher shutting down
LOG:  shutting down
LOG:  database system is shut down
 done
server stopped

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

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？

UPDATED ，因为他使用自己的Dockerfile，而不是使用github链接。

你能不能使用docker run命令来mkdir /docker-entrypoint-initdb.d。您应该将一些目录安装到容器中，以便它可以找到SQL文件。

我在https://github.com/kiasaki/docker-alpine-postgres/blob/master/Dockerfile读了Dockerfile并问自己SQL文件在哪里？它只是使目录没有复制SQL文件

docker-entrypoint.sh

然后，在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中，检查是否有任何要执行的SQL文件

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

我认为我们应该挂载一个SQL目录，比如

10 action * 20 videos for each * (500*350) 

features = input for SVM for training

docker alpine postgres in compose不执行docker-entrypoint-initdb.d脚本
