Unable to access the Cassandra from inside the Kubernetes cluster - java

I have a Cassandra cluster and a spring boot application in my Kubernetes cluster. They are in the same (default) namespace. The spring boot application needs to connect to Cassandra, but it's unable to do that. During the connection attempt, spring boot application receives the exception below:
Suppressed:

When I check the Cassandra pods, they are at running state. But the spring boot application gets refused. Any help would be greatly appreciated.


I solved the problem. I assumed that spring.data.cassandra.schema-action=CREATE_IF_NOT_EXISTS would create the key space but it wouldn't. So I created it manually.

And lastly I also tried Bitnami Helm Chart. And I recommend it too.

Spring Microservice Eureka Client Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://eureka-server:8761/eureka/},

I have one eureka Server that has multiple clients, I have deployed the micro services to to a docker container, whenever I do docker compose pull, and do docker compose up -d, Eureka server starts on http://localhost:8761/eureka/ instead of 'http://eureka-server:8761/eureka/.

When I do http://localhost:8761/eureka/ on the browser, I can reach the eureka-server but when I use the URL for docker http://eureka-server:8761/eureka/ I am not able. Any help is appreciated.

Add hostname like:
eureka-server:
image: remymumoh/eureka-server:latest
container_name: eureka-server
hostname: eureka-server

Reaching Eureka Server pod Kubernetes

I have 2 Springboot microservices, one is the Eureka server and the other one is the Gateway.
I can't find the right configuration to make the Gateway register to the Eureka server.
This is the eureka.yml with the K8s configuration:

This is the error I got when I check the logs of the Gateway's pod:
error on POST request for "http://eureka-0.eureka.default.svc.cluster.local:8761/eureka/apps/API-GATEWAY": eureka-0.eureka.default.svc.cluster.local; nested exception is java.net.UnknownHostException: eureka-0.eureka.default.svc.cluster.local
Following the documentation I've tried to set defaultZone property of the Gateway.application.properties file following this pattern:
172-17-0-3.default.pod.cluster.local:8761/eureka
But in this way too, I can't subscribe to the Eureka Server.

I resolved by modifying the Gateway.application.yml in this way:
eureka:
instance:
preferIpAddress: true
hostname: eureka-0
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://eureka-0.eureka:8761/eureka/
EDIT:
I'm encountering some problems in registering other microservices to the Eureka Server.
I've tried by increasing the replicas of the Eureka Server and made each microservice register to a dedicated replica, but as now this is not working.

Spring Boot Version : 2.2.7.RELEASE
Docker Hub Public image for spring boot : rahulwagh17/kubernetes:jhooq-k8s-springboot-jetty
One strange thing which i noticed when i use kubectl command manually to create deployment and service spring boot deployments goes perfectly fine.
vagrant#kmaster:~$ kubectl create deployment demo --image=rahulwagh17/kubernetes:jhooq-k8s-springboot-jetty
vagrant#kmaster:~$ kubectl expose deployment demo --type=LoadBalancer --name=demo-service --external-ip=1.1.1.1 --port=8080
(I followed this guide for deploying spring boot on kubernete - Deploy spring boot on kubernetes cluster)
I am just wodering is there something wrong with spring boot or my helm setup?
Here is my helm templates -

It appears the liveness probe (configured to contact the port named http) is killing your Pod since your container appears to be listening on :8080 but you've told kubernetes that it's listening on :80
Since a kubectl created deployment will not have any such specificity, kubernetes won't use a liveness probe and there you are
You can usually configure the spring application via an environment variable if you want to test that theory:
containers:
- name: springboot
env:
- name: SERVER_PORT
value: '80'
# and its friend, which is the one that
# you should be using for liveness and readiness

Cannot connect to mongo container

I had a previous question that (I think at least) that more or less became useless as I managed to fix the errors I was presented with.. However my new error, is that I cannot seem to connect to mongodb from within my docker image
docker-compose.yml:

application.properties:
spring.data.mongodb.database=myDb
spring.data.mongodb.host=172.28.0.2
spring.data.mongodb.port=27017
And the actual error:
com.mongodb.MongoSocketOpenException: Exception opening socket

Caused by: java.net.SocketTimeoutException: connect timed out

You’ve explicitly created a network in your docker-compose.yml file, and set your database to use that network. Docker Compose also creates a default network for you, and since your application doesn’t explicitly declare any networks, that attaches to only the default network. Then the two containers are on different networks and the one can’t reach the other.
The easiest solution here is to just delete all of the manual network configuration:
version: '3.1'
services:
company-repo-docker-app:
image: company-repo-image
build:
context: ./
depends_on:
- mongo
ports:
- '8080:8080'
mongo:
image: mongo
ports:
- '27017:27017'
The name of the service block will be a valid DNS hostname, and in your configuration you can set spring.data.mongodb.host=mongo.

I agree David answer is right. But here is a takeaway, your configuration works too, I tried with my sample and here is the result.
Issue is your app is not attached to the network.

Unable to launch springboot application without setting datasource

I'm trying to launch my SpringBoot application without configuring DataSource prior to compilation. If I do this, indicating the parameters, the application works normally, but I want to pass them through the JAVA_OPTS parameter when I run a docker container. Like that:
docker run --network public --link pg --name tm -e JAVA_OPTS="-Ddatasource.jdbcUrl=jdbc:postgresql://pg:5432/ggal1701 -Ddatasource.user=postgres -Ddatasource.password=postgres" -p 9000:8080 worker
I've tried many of the options I've seen on Stackoverflow, but none of them worked for me.

## Configuraciones de GRADLE
##
## Below are some of the gradle performance improvement settings that can be used as required, these are not enabled by default
##
## The Gradle daemon aims to improve the startup and execution time of Gradle.
## When set to true the Gradle daemon is to run the build.
## TODO: disable daemon on CI, since builds should be clean and reliable on servers
## un comment the below line to enable the daemon
#org.gradle.daemon=true
## Specifies the JVM arguments used for the daemon process.
## The setting is particularly useful for tweaking memory settings.
## Default value: -Xmx1024m -XX:MaxPermSize=256m
## un comment the below line to override the daemon defaults
#org.gradle.jvmargs=-Xmx1024m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
## When configured, Gradle will run in incubating parallel mode.
## This option should only be used with decoupled projects. More details, visit
## http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
## un comment the below line to enable parellel mode
#org.gradle.parallel=true
## Enables new incubating mode that makes Gradle selective when configuring projects.
## Only relevant projects are configured which results in faster builds for large multi-projects.
## http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand

You have two choices, both works correctly:
The first is to pass the values as JAVA_OPTS as follows (you are going through the parameters wrong):
docker run \
--network public \
--link pg \
--name tm \
-e JAVA_OPTS= \
"-Dspring.datasource.url=jdbc:postgresql://pg:5432/ggal1701
-Dspring.datasource.username=postgres \
-Dspring.datasource.password=postgres" \
-p 9000:8080 worker
The second is to pass the values as environment variables as follows (your mistake is the absence of quotes):
docker run \
--network public \
--link pg \
--name tm \
-e DATASOURCE_JDBC_URL="jdbc:postgresql://pg:5432/ggal1701" \
-e DB_USERNAME="postgres" \
-e DB_PASSWORD="postgres" \
-p 9000:8080 worker
Remember to specify these parameters in your configuration to use this second option. In the first one you don't have to configure anything directly.
As part of the devOps culture I never recommend hardcoding the settings and opting for the second option while it is intended for that purpose. They both have to work for you, and if you don't, you have some other mistake.
What you say about the hikariPool error is only a consequence of the datasource failure. Try one of these two ways and, in my professional opinion, opt for the second.
I leave you a good tutorial: Spring-boot tutorial

If your task is to pass jdbc url as a parameter during container startup there is not need to do it through DatabaseConfiguration. It can be done fairly simpler using placeholders in your configuration and environment variables in docker-run command.
Define placeholders in the configuration:
spring:
datasource:
url: ${JDBC_URL}
username: ${DATABASE_USERNAME}
password: ${DATABASE_PASSWORD}
And run the container like this:
docker run \
--network public \
--link pg \
--name tm \
-e JDBC_URL="jdbc:postgresql://pg:5432/ggal1701" \
-e DATABASE_USERNAME="postgres" \
-e DATABASE_PASSWORD="postgres" \
-p 9000:8080 worker
Note: docker link is deprecated functionality, you'd probably want to replace it.

Java properties should work according to the Spring Boot Externalized Configuration Docs. Might that be that you're not using the right name for the java properties?
From your production properties I see, for instance, that the property for the database URL is spring.datasource.url:
spring:
# Configuración de la BASE DE DATOS
datasource:
url: jdbc:postgresql://pg:5432/ggal1701
However you passing through the following Java Property:
-Ddatasource.jdbcUrl=jdbc:postgresql://pg:5432/ggal1701
I think instead you should use:
-Dspring.datasource.url=jdbc:postgresql://pg:5432/ggal1701
Another suggestion that always worked for me is to use environment variables instead of java properties. You can was them with equal simplicity to your Docker:
-e SPRING_DATASOURCE_URL=jdbc:postgresql://pg:5432/ggal1701
