docker cassandra and springboot microservices not connecting cassandra host - spring

Question

I am using spring boot cassandra microservices,
My docker file is ,
FROM openjdk:11-jdk-slim
VOLUME /tmp
ARG JAR_FILE=build/libs/*.war
COPY ${JAR_FILE} app.war
EXPOSE 8081
ENTRYPOINT ["java","-jar","/app.war"]
my docker compose is
version: "3"
services:
cassandra_node_1:
image: cassandra:3.11.5
container_name: cassandra_node_1
ports:
- 9042:9042
hostname: cassandra_node_1
mem_limit: 2g
healthcheck:
test: ["CMD", "cqlsh", "-e", "describe keyspaces" ]
interval: 5s
timeout: 5s
retries: 60
environment:
- CASSANDRA_SEEDS=cassandra_node_1
- CASSANDRA_DC=datacenter1
milk-vendor-services:
container_name: milk_vendor_1
build:
context: .
restart: on-failure
ports:
- 8081:8081
environment:
- spring.data.cassandra.contact-points=cassandra_node_1
- spring.data.cassandra.port=9042
- spring.data.cassandra.keyspace-name=milk_vendor
- spring.data.cassandra.local-datacenter=datacenter1
- spring.data.cassandra.schema-action=CREATE_IF_NOT_EXISTS
depends_on:
- cassandra_node_1
while I running the above using "docker compose up". I am getting below error, where as working fine without docker.

Answer 1

So a few things caught my eye here:
FROM openjdk:11-jdk-slim
...
image: cassandra:3.11.5
Cassandra version <= 3 will only run on Java 8 (or lower). It will fail to start on anything else.
Error connecting to Node(endPoint=localhost:9042,
- spring.data.cassandra.contact-points=cassandra_node_1
I'm curious as to what cassandra_node_1 resolves to, as I'm pretty sure it's not localhost. Note, that you can only connect to the endpoints that are being broadcasted by Cassandra. So if your listen_address and rpc_address are both set to localhost in your cassandra.yaml, you'll only ever be able to connect locally and only by the values of localhost or 127.0.0.1. If you need to be able to reach it remotely at cassandra_node_1 then that's what those _address properties should be set to.
