下面的 Dockerfile 是针对当前版本的 ibm_db 和 ibm_db_sa 以及 centos7 的 SQLAlchemy 的镜像。
它适用于 x64 架构，无需编译 ibm_db。
更改 Dockerfile 以省略镜像中不需要的包。较小的图像可以更快地构建并使用更少的存储空间。
此 Dockerfile 显示了复制预配置 db2dsdriver.cfg 的可选步骤。进入图像到默认位置。
这让我可以使用 db2cli在使用 python ibm_db 之前，在容器中确保与数据库的连接。
db2cli 需要 LD_LIBRARY_PATH 来包含 clidriver\lib 目录，以确保 db2cli validate 将运行。
