Re: Cassandra and Docker

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

Hello,

Having Cassandra in Docker is nice because you don't have anything to install.

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

Personally, I'd recommend learning Docker on its own or Cassandra on its
own. I wouldn't try to do it at the same time if you're new to both
technologies. 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!

  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.

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
