Docker + Dev Env • Docker relies on Linux kernel capabilites… so no native docker in OS X • We use OSX for dev, so we run vagrant and the CoreOS vagrant file • Install Docker userland tools in OS X and forward ports to the vagrant box running CoreOS • Our env is a little strange, we a single cassandra instance on a single CoreOS vm.

Swarm uses the Docker API as its front end, which helps us to use various tools to control it. Note: We enable restart: always to keep our Cassandra containers up and because Swarm may deploy the containers too fast for Cassandra to bootstrap correctly causing a Other bootstrapping/leaving/moving nodes detected error and the restart will try and recover the bootstrap correctly when this happens which in this case you would see a Detected previous bootstrap failure; retrying message. Now on your Primary Swarm Manager node, you can run the docker info command to see your Swarm cluster. by It’s a self-organizing group of engines that is used to enable pluggable backends. Continue reading. Cassandra states that in-memory approaches to data storage can give you “blazing speed” however the cost of being limited to small data sets may not be so desirable. The advantage of a container environment like docker-swarm or kubernetes is that you can run Cassandra with its default settings and without additional security setup. Hi, I have been trying to make a cassandra cluster using docker swarm and the official cassandra image, but I noticed that after I changed the cassandra.yaml file (e.g. Happy Swarming!

When I execute the below lines of code it starts then stops the docker without connecting to the cluster. This makes our Cassandra cluster very flexible and means the Cassandra containers will always be able to connect to each other no matter where they are started as long as they are part of the network.
