redash oracle 数据源docker 镜像

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'

docker-compose 运行

• docker-compose 文件

version: '3'

services:

  server:

    image: dalongrong/redash-oracle:7.0.0.b18042

      - "80:80"

    depends_on:

      - server

    links:

      - server:redash

    restart: always

• 环境变量说明
  详细的环境变量可以参考opt/redash/env
• 启动

 

docker-compose up -d

docker-compose run --rm server create_db

效果

说明

docker 镜像我已经push dockerhub 了dalongrong/redash-oracle
