I deployed a distributed cluster successfully with DolphinDB Docker Package. But how to check what version of DolphinDB has been installed? I wonder where to specify the version to download so that I can use an earlier version.

Here's the tutorial: https://github.com/dolphindb/Tutorials_CN/blob/master/docker_deployment.md

I have a brief check, this project hard code to use v0.95.3 version's DolphinDB. You had to modify Dockerfile of it to use old one.

Steps as next:

  1. Download the deploy package from here, just as the readme you give said.

  2. Unzip this package, you will find a sub-package with the name Dockerbuild, enter into this folder, use a editor to modify the Dockerfile, change all V0.95.3 to the version which you needed:

    FROM centos:latest

RUN mkdir -p /data/ddb
ADD http://www.dolphindb.com/downloads/DolphinDB_Linux64_V0.95.3.zip /data/ddb/
RUN yum install -y unzip
RUN yum install -y wget
RUN (cd /data/ddb/ && unzip /data/ddb/DolphinDB_Linux64_V0.95.3.zip)
RUN rm -rf /data/ddb/DolphinDB_Linux64_V0.95.3.zip
RUN chmod 755 /data/ddb/server/dolphindb
RUN mkdir -p /data/ddb/server/config
ADD http://www.dolphindb.com/downloads/ZLIB_V0.95.0.zip /data/ddb/server/
RUN (cd /data/ddb/server/ && unzip -n /data/ddb/server/ZLIB_V0.95.0.zip)
RUN rm -rf /data/ddb/server/plugins/README.md
RUN rm -rf /data/ddb/server/ZLIB_V0.95.0.zip
ADD http://www.dolphindb.com/downloads/AWSS3_V0.95.0.zip /data/ddb/server/
RUN (cd /data/ddb/server/ && unzip -n /data/ddb/server/AWSS3_V0.95.0.zip)
RUN rm -rf /data/ddb/server/plugins/README.md
RUN rm -rf /data/ddb/server/AWSS3_V0.95.0.zip
ADD default_cmd /root/
RUN chmod 755 /root/default_cmd
ENTRYPOINT ["/root/default_cmd"]

  3. Finally, follow the guide to build:

    cd ./DolphinDB-Docker-Compose/Dockerbuild
docker build -t ddb:latest ./
