/docker-entrypoint-initdb.d 目录中的 SQL 脚本未执行

Question

我已经在基于 oraclelinux:7.1 映像（Docker 版本 1.12.5）的 docker 容器中安装了 Oracle 12c。不过有一个小问题。运行容器时，我在目录 /docker-entrypoint-initdb.d 中的任何脚本都不会被执行（它们创建 DB 用户、执行授权、设置模式等）。这可能是什么问题？

/docker-entrypoint-initdb.d 和其中的所有 SQL 文件的权限设置为 777。我可以使用默认系统用户登录数据库。

您将在下面找到 Dockerfile 复制 SQL 脚本：

FROM oracle-12c:latest

USER oracle
ENV ORACLE_SID ORCL
ENV ORACLE_HOME /u01/app/oracle/product/12.1/db_1
ENV PATH $PATH:$ORACLE_HOME/bin
USER root

RUN echo $PATH
COPY init-scripts/* /docker-entrypoint-initdb.d/

EXPOSE 1521

我的容器中的日志：

Answer 1

我假设你说的是 docker-entrypoint.sh 的那部分：

for f in /docker-entrypoint-initdb.d/*; do
    case "$f" in
        *.sh)     echo "[IMPORT] $0: running $f"; . "$f" ;;
        *.sql)    echo "[IMPORT] $0: running $f"; echo "exit" | su oracle -c "NLS_LANG=.$CHARACTER_SET /u01/app/oracle/product/12.1.0/xe/bin/sqlplus -S / as sysdba @$f"; echo ;;
        *)        echo "[IMPORT] $0: ignoring $f" ;;
    esac
    echo
done

我一直在为 MySQL 和 PostgreSQL docker 处理同样的问题，到目前为止我发现的解决方法是遍历绝对路径。在我们找到可能非常简单的实际解释之前，您可以这样做：

1. 在 Dockerfile 中，执行如下操作：

   # docker-entrypoint.sh
   COPY docker-entrypoint.sh /usr/local/bin/
   RUN chmod +x /usr/local/bin/docker-entrypoint.sh
   
   # Database scripts
   COPY init-scripts/ /usr/local/bin/docker-entrypoint-initdb.d/
   RUN chmod -R +x /usr/local/bin/docker-entrypoint-initdb.d
   

2. 然后，在 docker-entrypoint.sh 中，更改

    for f in /docker-entrypoint-initdb.d/*; do
to

    for f in /usr/local/bin/docker-entrypoint-initdb.d/*; do

然后构建并运行映像。它应该已经运行了你的脚本。 希望对您有所帮助。
