Cassandra and Docker
Hi
I want to run Cassandra within Docker. I am new to both to be honest.
1. Is it better to use Cassandra within Docker or is it better to install/run Cassandra directly on a VM in the cloud?
2. Is there a Docker image for Cassandra (for 3.11.4) which I can pull/use?
3. How will data be stored if I use Docker/Cassandra? If the container stops, then would re-running the image use existing data or would I use lose data?
4. How would I configure a DC if I use Docker/Cassandra? Say I run 3 containers on 3 VMs for RF=3, how would I provide this configuration through Docker?
Thanks
Manu

1. Use what works for you. People are starting to use C* in Docker though. Lots of info on google for this.
2. https://hub.docker.com/_/cassandra
3. You probably want to mount an external volume in the container - https://docs.docker.com/storage/volumes/
4. Connect to C* with cql and specify the RF with a CREATE/ALTER KEYSPACE command.

What If I were to deploy this in AWS? Is there a straightforward way to allocate resource in AWS and tell Cassandra about them?
thanks

Cassandra can be installed in multiple ways but this is tarball and as such not for windows.
The Docker hub website is very detailed about what are the options you can usem which ports to open (as stated by Rhys)
https://hub.docker.com/_/cassandra/#!
I would propose you to go with docker-compose in a file where everyhing is already defined for you.
I have attached 2 files. One for a single node and one for 1 dc and 3 nodes for Cassandra 3.
docker-compose -f cassandra3-1dc-1node.yaml
docker exec -it `docker ps | grep cassandra-node1 | cut -b 1-12` cqlsh
Cheers

It's hard enough as it is for experienced users. If you're using both and you run into issues, you will find it difficult to know whether the problem is Docker, Cassandra, or both. As always, YMMV. Good luck. Cheers!

Personally, I'd recommend learning Docker on its own or Cassandra on its
