Question

我已经在基于oraclelinux：7.1镜像（Docker版本1.12.5）的docker容器中安装了Oracle 12c。但是有一个小问题。运行容器时，目录/docker-entrypoint-initdb.d中的所有脚本都不会被执行（它们创建数据库用户，执行授权，设置模式等）。这可能是什么问题？

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

下面你会发现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：

我假设您正在谈论docker-entrypoint.sh的那一部分：

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，到目前为止我找到的解决方法是循环一个绝对路径。在我们找到可能非常简单的实际解释之前，您可以执行以下操作：

在Dockerfile中，执行以下操作：

# 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

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

然后构建并运行图像。它应该运行你的脚本。希望有所帮助。

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