TestContainers embedded db cannot find tables - java

I have created a spring boot app with the following setup:

I have a look at the db when debugging and sure enough no tables exist on that postgres container, am I missing something in terms of setup, my understanding was that:
spring.jpa.hibernate.ddl-auto=create
Along with the data in data.sql will be all the setup required to create and populate my tables within the DB container.
Here is my dockerFile:
FROM openjdk:8
ADD target/ghix-ticket-0.0.1-SNAPSHOT.jar ghix-ticket-0.0.1-SNAPSHOT.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "ghix-ticket-0.0.1-SNAPSHOT.jar"]
and my dockercompose:

How to connect to docker-compose port from docker and locally?

I am using spring boot 2.5.3 and postgreSQL for backend.
I want this app to run on localhost:5000/api/v1/customers as well as from docker-compose.
application.properties:
server.port=5000
#Database setup
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.hibernate.show-sql=true
spring.datasource.url=jdbc:postgresql://localhost:5432/customers
spring.datasource.username=postgres
spring.datasource.password=postgres
This works with localhost, with mvn spring-boot:run
But, when I use the following application.properties settings from localhost to db
server.port=5000
#Database setup
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect

This works localhost:5000/api/v1/customers when docker-compose is up.
Is there a way we can have condtional name for host in this line?Is there any other way?
spring.datasource.url=jdbc:postgresql://db:5432/customers
Since the host development environment and the container runtime environment are different, you can use environment variables to differentiate between them. Spring Boot knows how to set Spring properties from environment variables. So I'd recommend:
In your application.properties file, set spring.datasource.url to the localhost URL you'd use in development.
In your Compose setup, set the SPRING_DATASOURCE_URL environment variable to the name specific to that Compose setup
version: '3.8'
services:
db: { ... }
app:
environment:
- SPRING_DATASOURCE_URL=jdbc:postgresql://db:5432/customers
...
Do not create a separate Spring profile per environment; you would not want to recompile your jar file if you changed the database name or password, or deployed this in Kubernetes, or used a cloud-hosted database like Amazon RDS, or...
So, you want to be able to run both locally and from docker?
If that's the case, you need to extract the database connection string to an environment variable that you set at runtime
spring.datasource.url = ${DB_HOST}:${DB_PORT}/
spring.datasource.username = ${DB_USERNAME}
spring.datasource.password = ${DB_PASSWD}
Or you can introduce two different property files that get set from a Spring profile, which you also would set at runtime; Refer SPRING_PROFILES_ACTIVE environment variable
Based on what I see, you are not supposed to use localhost on spring.datasource.url because your docker is within the container itself, you should be using
jdbc:postgresql://host.docker.internal:5432/customers instead. For more details, you can view from this link https://docs.docker.com/desktop/windows/networking/#i-cannot-ping-my-containers
Is there a way we can have condtional name for host in this line?Is there any other way?
As for this, it would be prefered to set it as an environmetn variable on your docker compose file and connect using dbconn url
If you are using linux as your operating system on which you are running your docker , you can set this property
network_mode: host
on both the containers, this will attach your container's port to your localhost port.
You will need to remove the port forwarding config for this to work.

Spring application stuck in start

I have a problem since I export and import a spring project, and it is that now it takes more than 70 seconds to start. Get stuck in Triggering deferred initialization of Spring Data repositories ...

spring.datasource.url=jdbc:mysql://localhost:3306/innodb
spring.datasource.username=root
spring.datasource.password=1234
My application works when I build and run the project in Intellij but not when I try and build my docker image. I am using MySQL and have just been connecting on localhost on port 3306.
The error message seems to indicate the issue is failing to connect to the database. From your settings, it appears that you are trying to connect to the DB using localhost:3306. That will not work when you are running the application in a container because docker creates its own network which is separate from you machine’s network. So, localhost in the container does not refer to your machine.
You need to instead setup a docker network that will allow your container to access the database in a specific IP address.
Here is an article with the specifics:
https://nickjanetakis.com/blog/docker-tip-35-connect-to-a-database-running-on-your-docker-host
Note that I have assumed from your post, that the DB is installed in your host machine. If it is not and the DB is running in its own container, the you need to create a docker network and attach both containers to that network.
I had the same issue and resolved it by changing localhost to the service name on which MySQL was running.
Below is my docker-compose and application.properties files
docker-compose.yml
version: '3.8'
services:
app:
container_name: tvms
build:
context: .
dockerfile: Dockerfile

#datasource
spring.datasource.url=jdbc:mysql://db:3306/db_name
spring.datasource.username=root
spring.datasource.password=*****
For me below solution worked
change your datasource url from
This:
spring.datasource.url=jdbc:mysql://localhost:3306/innodb
To:
spring.datasource.url=jdbc:mysql://localhost:3306/innodb?useSSL=false

I got whitelabel error page instead of eureka dashboard

I'm following a tutorial about Eureka to start up a sample eureka server ,I followed exactly the same steps but i get a whitelabel insteed of eureka dashbord, I will share with you all the configuration that I made

I do not know where the problem is it has been several hours that I am looking for a solution, if you have ideas do not hesitate to share them,
Thanks .
I guess you didn't add #EnableEurekaServer annotation to your main app
It should be like this
#SpringBootApplication
#EnableEurekaServer
public class DiscoveryServerApplication {
…
}

Sping Boot Java backend application process gets killed

I have packaged my spring boot rest backend with mvn package.
When I run the jar on the server with java -jar ... the application starts and gets killed after a few seconds.
I also see that on the linux top view, that the java process goes over 300% CPU. Is that maybe the reason the process gets killed? And if yes, what can I do?
My spring boot application is not very big. Actually its almost empty.

I only have three files in my project:
1.:
package ...
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class CarorderprocessApplication {
public static void main(String[] args) {
SpringApplication.run(CarorderprocessApplication.class, args);
}
}
Then I have application.properties file with information for database connection and port.
pom.xml:
https://maven.apache.org/xsd/maven-4.0.0.xsd">
4.0.0
org.springframework.boot
spring-boot-starter-parent
2.0.2.RELEASE

Some ideas to check:
Try to run as detached: java -jar yourapp.jar &
Try ( just once ) to run under root
Check logs: journalctl -ex for details of who exactly has killed your application.
Depends on results, can plan next steps - typically which settings to adjust.
