After changing the Eureka port number from default port to custom port, when running the Eureka client it is showing following error:

it is showing

Change configuration for the Eureka registry server eureka.client.serviceUrl.defaultZone like following (YAML syntax):
eureka:
client:
#registerWithEureka: false
#fetchRegistry: false
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

I'm currently working on my microservices project with java spring boot.
I dockerized everything correctly, but as soon as I try to implement everything on Kubernetes it starts to give me problems.
I run the command kubectl logs mypodname to look at the error and it prints me the following:

Even if Eureka doesn't recognize the microservice, the microservice itself works..
I've tried even to add a / at the end of the defaultZone attribute but nothing.
This is the link to my repo: https://github.com/hassanmarji96/Backend_Littleshops
Followed this link for continuous deployment using Cloud Build and GitHub actions in spring-boot app.
petomalina.medium.com/
Everything is working fine except for when service is trying to access the database using the following command to deploy.
gcloud run deploy my-service \
--region europe-west1 \
--image gcr.io/${{ secrets.GCP_PROJECT_ID }}/my-service \
--platform managed \
--allow-unauthenticated \
--project ${{ secrets.GCP_PROJECT_ID }} \
--add-cloudsql-instances [instance-name] \
--set-env-vars DATASOURCE_URL=jdbc:mysql://google/[dbname]?cloudSqlInstance=[instance-name]&socketFactory=com.google.cloud.sql.mysql.SocketFactory&useSSL=false
I have also added role for Cloud SQL client against the service account, tried using both public ip, private ip and this format
jdbc:mysql://google/[dbname]?cloudSqlInstance=[instance-name]&socketFactory=com.google.cloud.sql.mysql.SocketFactory&useSSL=false
This is my app.prop file:
spring.datasource.url=${DATASOURCE_URL}
spring.datasource.username=sa
spring.datasource.password=pswd
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
But still it gives this error:
com.mysql.cj.jdbc.exceptions.CommunicationsException: \
Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. \
The driver has not received any packets from the server.

Can someone please point me in the right direction?

It is working locally though with ConnectionPoolContextListener
java.net.SocketTimeoutException refers to a connection time out before a remote host's response can be received. The cause can be a local network issue, proxy or firewall incorrectly configured. If you are using a private IP, you need to check that the docker bridge network's IP range. Here is what the documentation says:
If a client cannot connect to the Cloud SQL instance using private IP, check to see if the client is using any IP in the range 172.17.0.0/16. Connections fail from any IP within the 172.17.0.0/16 range to Cloud SQL instances using private IP. Similarly, Cloud SQL instances created with an IP in that range are unreachable. This range is reserved for the docker bridge network.
To resolve some of the issues, you are experiencing, follow the documentation here and post any error messages you receive, for example, you could try:
Try the gcloud sql connect command to connect to your instance. This command authorizes your IP address for a short time. You can run this command in an environment with Cloud SDK and mysql client installed. You can also run this command in Cloud Shell, which is available in the Google Cloud Console and has Cloud SDK and the mysql client pre-installed.
Temporarily allow all IP addresses to connect to an instance. For IPv4 authorize 0.0.0.0/0 (for IPv6, authorize ::/0. After you have tested this, please make sure you remove it again as it opens up to the world!
Are you using connection pools?
If not, I would create a cache of connections so that when your application needs to link to the database, it can get a temporary connection from the pool. Once the application has finished its operation, the connection returns to the pool again for later use. For this to work correctly, the connection needs to be open and closed efficiently and not waste any resources.
application.yml of my microservice (client to Eureka)
spring:
application:
name: queue1
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8762/
server:
port: 7777
app:
id: ${random.uuid}
application.yml of Eureka
eureka:
instance:
hostname: peer1
client:
register-with-eureka: false
fetch-registry: false
server:
port: 8762
I am starting Eureka in port 8762 and referring to that in my microservices.
Microservice is failing to register itself with Eureka.
Following is the exception from microservice logs.

Now the most important thing is, everything is perfectly fine if I change the Eureka server port and the microservice's Eureka registration port to 8761 !!!! Registration of microservice is succeding in this case.
Did this multiple times before posting the question and it is behaving like this.
Any inputs here would be very much helpful.
I had the same issue, it was due to spring security dependencies in the Eureka server project. After adding the #EnableWebSecurity code to the eureka server application fixed for me.
#EnableWebSecurity
static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
}
}

I am having issues getting the jhipster registry to work with cloud foundry. Here's what I am trying to do
I deployed Jhipster registry to cloudfoundry. I see the Jhipster Registry app running fine. I can see the app dashboard in my browser.
Now I have a microservice app created on my machine. I try to connect to the Jhipster from the microservice app running on my machine.
eureka configuration in my application-dev.yml
eureka:
instance:
hostname: jhipsterregistry.run.asv-pr.ice.predix.io
prefer-ip-address: true
nonSecurePortEnabled: false
securePortEnabled: true
client:
registerWithEureka: true
fetchRegistry: true
service-url:
defaultZone: https://admin:${jhipster.registry.password}#jhipsterregistry.run.asv-pr.ice.predix.io/eureka/
Configuration in my bootstrap.yml file
spring:
application:
name: AttendanceDBService
profiles:
# The commented value for `active` can be replaced with valid Spring profiles to load.
# Otherwise, it will be filled in by maven when building the WAR file
# Either way, it can be overridden by `--spring.profiles.active` value passed in the commandline or `-Dspring.profiles.active` set in `JAVA_OPTS`
active: #spring.profiles.active#
cloud:
config:
fail-fast: false # if not in "prod" profile, do not force to use Spring Cloud Config
uri: https://admin:${jhipster.registry.password}#jhipsterregistry.run.asv-pr.ice.predix.io/config
I get below error ...
