Hi
I want to run cassandra docker image and want to connect it with my application
running in another container. I am on Windows10 and both containers are running
on same Windows10 Home machine. I also have Cassandra installed on the machine
as standalone application (without Docker).
I thought to use host.docker.internal as domain name in both the applications.
But when I start cassandra image, I get error
org.apache.cassandra.exceptions.ConfigurationException: Unable to bind to
address host.docker.internal/192.168.65.2:7000. Set listen_address in
cassandra.yaml to an interface you can bind to, e.g., your private IP address
on EC2
Question 1) Why is host.docker.internal resolving to 192.168.65.2/7000?.
Shouldn't it be 192.168.1.12 as that is what is configured in my etc/hosts file
on Windows 10
C:\Users\manuc>ping host.docker.internal

I also tried explicitly specifying 192.168.1.12 when starting cassandra images
but I get similar error.
The only way I am able to start the container is by running docker run
ca795bbd8fd7 but in this case, cassandra listens at address 0.0.0.0 for cqlsh
Starting listening for CQL clients on /0.0.0.0:9042 (unencrypted)..
But in this case, my other docker application or cqlsh of the standalone
CasSandra is unable to connect with it (running on the same windows machine)
C:\Users\manuc>cqlsh host.docker.internal 9042
Connection error: ('Unable to connect to any servers', {'192.168.1.12':

connection could be made because the target machine actively refused it")})

Question 2) How can I make Cassandra container connect with my other
application container or cqlsh of my standalone Cassandra installation?
