RE: Cassandra container, Google Cloud and Kubernetes
Hi Erick It might be useful if the answer from Willrof is added to your Wiki. It solved my problem and could be very useful to people wanting to run Cass-Operator.

RE: Cassandra container, Google Cloud and Kubernetes
In continuation to my previous message, I can see the nodes are up on the GCP dashboard. I can ping the external IP from my laptop but when I run `cqlsh external_ip 9042` then the connection fails. How do I go about connecting the K8s/Cassandra cluster to outside work so that my web application can access it.

Re: Cassandra container, Google Cloud and Kubernetes

C* 3.11.4 is over a year old now and there are some important fixes in 3.11.5 and 3.11.6 that I think should be sufficient motivation to use 3.11.6. If it helps, I'll single these 2 out: - CASSANDRA-14096 Repair merkle tree size causes OOM [2] - CASSANDRA-15035 Fix bad UDT sstable metadata serialization headers written by C* 3.0 on upgrade and in sstablescrub [3] Cheers!

RE: Cassandra container, Google Cloud and Kubernetes
Hi Erick It seems that 3.11.4 is not supported. I am happy to move up to 3.11.6 but is 3.11.6 backward compatible with 3.11.4? I don’t want start changing my driver code in the application. “ Cass Operator release 1.2.0 is compatible with Apache Cassandra 3.11.6 and DSE 6.8.0+. Cass Operator is not supported and will not function with prior releases of Cassandra or DSE. Furthermore, this release of Cass Operator is compatible only with specific Cassandra and DSE docker images that are hosted in the DataStax Docker Hub repository. Prior (pre-release) DataStax Labs releases of DSE 6.8.0 will not function with the current Cass Operator.” Thanks Manu From: Manu Chadha<mailto:manu.cha...@hotmail.com> Sent: 25 June 2020 07:12 To: user@cassandra.apache.org<mailto:user@cassandra.apache.org> Subject: RE: Cassandra container, Google Cloud and Kubernetes Dear Erick I have started looking at Cass.
