Hi,
We can cater for multiple types (spark, spark-py and spark-r) and spark
versions (assuming they are downloaded and available).
The challenge is that these docker images built are snapshots. They cannot
be amended later and if you change anything by going inside docker, as soon
as you are logged out whatever you did is reversed.
For example, I want to add tensorflow to my docker image. These are my
images

*Hm that keras is not there*. The docker Image cannot be altered after
build! So once the docker image is created that is just a snapshot.
However, it will still have tons of useful stuff for most
users/organisations. My suggestions is to create for a given type (spark,
spark-py etc):
1. One vanilla flavour for everyday use with few useful packages
2. One for medium use with most common packages for ETL/ELT stuff
3. One specialist for ML etc with keras, tensorflow and anything else
needed
These images should be maintained as we currently maintain spark releases
with accompanying documentation. Any reason why we cannot maintain
ourselves?
