Using the Datastax C# Driver I'm trying to connect to Cassandra which was deployed to Azure Kubernetes Services using a Bitnami helm chart.
var cluster = Cluster.Builder()
.AddContactPoint("127.0.0.0") // example IP
.WithCredentials("cassie", "some-pass")
.Build();
When trying this locally I use kubectl port-forward
, but when I'm uploading my service to Kubernetes I want to use service name. Many applications shown to me by colleagues use just that. When I add the link that helm chart gives to me after I install it
Cassandra can be accessed through the following URLs from within the cluster:
- CQL: service-name.some-namespace.svc.cluster.local:9042
I'm unable to connect, I'm getting a Cassandra.NoHostAvailableException and I have to use an IP.
How to solve this problem. The IP changes every time I redeploy. How can I use the name instead of the IP?
Apparently, providing the DNS with format "DNS:PORT" as a parameter for AddContactPoint was not working. Using the method WithPort did the trick.
var cluster = Cluster.Builder()
.WithPort(PORT)
.AddContactPoint("dns")
.WithCredentials("cassie", "some-pass")
.Build();
