The Dockerfile below is for an image to current versions of ibm_db and ibm_db_sa and SQLAlchemy for centos7.

It works for x64 architecture without needing to compile ibm_db.

Change the Dockerfile to omit the packages that you do not need in your image. Smaller images build quicker and use less storage.

This Dockerfile shows an optional step to copy a preconfigured db2dsdriver.cfg into the image to the default location.

This lets me use db2cli in the container to ensure connectivity to databases before using python ibm_db.

db2cli needs LD_LIBRARY_PATH to contain the clidriver\lib directory, to ensure db2cli validate will run.
