Initialization script

[AnderUstarroz]

This is a feature request,
Some docker images like the official postgres allow initialization scrips during execution. Just adding some SQL or Shell files to the folder /docker-entrypoint-initdb.d and docker will execute all these scripts after building the image, so we are able to create schemes, add initial data ETC... I believe this is a great feature and wouldn't be really hard to add to cassandra, just take a look at postgres entry-point.sh .

This one feels a bit more complicated than Mysql/Postgres. The other images start the sql server with a limited listening state, ie only localhost or unix domain socket, in order to complete sql imports and scripts before stopping the server and starting it again as pid 1 with normal network access. It would be a fairly major change to the current script to prepare the server with localhost listen and broadcast addresses, and to only do so if this is the first server, ie no CASSANDRA_SEEDS.

If this is something that is commonly wanted, I would not be opposed to a PR.

Would love to see that also. Any suggestions about a workaround on this?

There are a couple workarounds discussed over in #65 if you have an oversimplified deployment.

Closing with a similar rationale to #94 -- the proper deployment of Cassandra is clustered, and is much more complicated to get right automatically. It is not recommended to use a standalone deployment, and I fear such a feature would encourage folks to do so (since it couldn't possibly work with a cluster properly and/or detect clustered operation). For folks that really want to go there, building something like that on top of the provided image shouldn't be too much work. 👍
