redash 官方的docker 镜像是没有包含oracle的，需要我们自己添加，参考了一个docker 镜像进行了简单的修改
Dockerfile
FROM redash/redash:7.0.0.b18042
USER root
# Oracle instantclient
ADD oracle/instantclient-basic-linux.x64-12.2.0.1.0.zip /tmp/instantclient-basic-linux.x64-12.2.0.1.0.zip
ADD oracle/instantclient-sdk-linux.x64-12.2.0.1.0.zip /tmp/instantclient-sdk-linux.x64-12.2.0.1.0.zip
ADD oracle/instantclient-sqlplus-linux.x64-12.2.0.1.0.zip /tmp/instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
RUN apt-get update -y
RUN apt-get install -y unzip
RUN unzip /tmp/instantclient-basic-linux.x64-12.2.0.1.0.zip -d /usr/local/
RUN unzip /tmp/instantclient-sdk-linux.x64-12.2.0.1.0.zip -d /usr/local/
RUN unzip /tmp/instantclient-sqlplus-linux.x64-12.2.0.1.0.zip -d /usr/local/
RUN ln -s /usr/local/instantclient_12_2 /usr/local/instantclient
RUN ln -s /usr/local/instantclient/libclntsh.so.12.1 /usr/local/instantclient/libclntsh.so
RUN ln -s /usr/local/instantclient/sqlplus /usr/bin/sqlplus
RUN apt-get install libaio-dev -y
RUN apt-get clean -y
ENV ORACLE_HOME=/usr/local/instantclient
ENV LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/instantclient
COPY oracle.py /app/redash/query_runner/oracle.py
RUN pip install cx_Oracle==5.3
USER redash
#Add REDASH ENV to add Oracle Query Runner
ENV REDASH_ADDITIONAL_QUERY_RUNNERS=redash.query_runner.oracle
说明
实际上官方文档提供了一些简单的说明在 oracle
内容如下：
# Requires installation of, or similar versions of:
# oracle-instantclient12.2-basic_12.2.0.1.0-1_x86_64.rpm
# oracle-instantclient12.2-devel_12.2.0.1.0-1_x64_64.rpm
cx_Oracle==5.3
上边的镜像参考了https://github.com/joaoleite/redash_oracle，同时指定新oracle client 以及python 包
同时如果需要启用oracle，需要添加REDASH_ADDITIONAL_QUERY_RUNNERS 环境变量，内容为
ENV REDASH_ADDITIONAL_QUERY_RUNNERS=redash.query_runner.oracle
以上同时包含了一个对于中文乱码的问题oracle.py, 需要添加的代码
import os
os.environ['NLS_LANG'] = 'AMERICAN_CHINA.ZHS16GBK'
