redash 官方的docker 鏡像是沒有包含oracle的，需要我們自己添加，參考了一個docker 鏡像進行了簡單的修改
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 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
說明
實際上官方文檔提供了一些簡單的說明在 oracle
內容如下：
# 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
上邊的鏡像參考了https://github.com/joaoleite/redash_oracle，同時指定新oracle client 以及python 包
同時如果需要啟用oracle，需要添加REDASH_ADDITIONAL_QUERY_RUNNERS 環境變量，內容為
ENV REDASH_ADDITIONAL_QUERY_RUNNERS=redash.query_runner.oracle
以上同時包含了一個對於中文亂碼的問題oracle.py, 需要添加的代碼

os.environ['NLS_LANG'] = 'AMERICAN_CHINA.ZHS16GBK'
