In this lab, we will see how to quickly start ScyllaDB by running a single instance using Docker. We will then see how to run the CQL Shell.
Please ensure that your environment meets the following prerequisites:
- Docker for Linux, Mac, or Windows. Please note that running ScyllaDB in Docker is only recommended to evaluate and try ScyllaDB. For best performance, a regular OS install is recommended.
- 3GB of RAM or greater for Docker.
- If you are using Linux, you will need docker-compose.
Note: In addition to the instructions provided here, which allow you to run the lab on a machine with Docker, you can find this lab in the Killercoda learning environment here. The Killercoda environment provides an interactive virtual machine where you can execute all the commands directly from your browser without the need to configure anything.
First, we’ll start a single instance and call it ScyllaDBU:
docker run --name scyllaU -d scylladb/scylla:4.5.0 --overprovisioned 1 --smp 1
Notice that some files might be downloaded in this step. After waiting for a few seconds, we’ll verify that the cluster is up and running with the Nodetool Status command:
docker exec -it scyllaU nodetool status
The node scyllaU has a UN status. “U” means up, and N means normal. Read more about Nodetool Status Here.
Finally, we use the CQL Shell to interact with ScyllaDB:
docker exec -it scyllaU cqlsh
The CQL Shell allows us to run Cassandra Query Language commands on ScyllaDB, as we will see in the next part.
