com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure - Fails only when deploying the app in docker

Hello I am trying a spring boot mysql with docker.
I was able to test my application when my app is running on local and connecting the my-sql which is launched as docker container.
But when try the same application deployed in docker (now both my app and db are deployed in docker) it fails with Communications link failure
I think we may need to make some correction in the url.
Can you please help.

app-mysql | com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

Your MySQL and Spring Boot application runs in the seperate container. So I recommend using the internal address and port instead of using external port and address.
To do this, change your application.properties file this way.
spring.datasource.url=jdbc:mysql://local-mysql:3306/docker-mysql
Although it is the correct solution that ssj specifies, you can use the restart policy in your app-mysql image, similar to your local-mysql image instead.
restart: unless-stopped
This allows your Spring Boot application to restart due to errors until your database application is ready and available.

The problem here is with the depends_on tag of docker compose.
The tag 'depends_on' regulates the order in which the containers are launched using compose, but it is not guaranteeing that the container that we depend on will be ready so that current container will start without any problem.
The possible solution is we need to make the current container wait until the container that we depend on is completely ready.
Many such wait tools are discussed in the following url.
https://docs.docker.com/compose/startup-order/
I used the docker-compose-wait from https://github.com/ufoscout/docker-compose-wait.
With that, I modified by Dockerfile as follows
FROM openjdk:17
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.9.0/wait /wait
RUN chmod +x /wait
COPY target/*.jar app.jar
CMD ["/wait", "java","-jar","/app.jar"]
And Made corrections to the compose as follows, ie I added a command tag and required environment variables for the tool
command: sh -c "/wait && java -jar app.jar"
environment:
WAIT_HOSTS: local-mysql:3306
WAIT_TIMEOUT: 300
WAIT_SLEEP_INTERVAL: 30
WAIT_HOST_CONNECT_TIMEOUT: 30
And if you see that, when run from the container, I no more depend on the container's exported port. Because the exported port comes into picture only when you are trying to access the container from host machine where your docker engine is running. As my app and dbserver ie local-mysql (in this case), connected in the same network, I simply access my DB server with container-name:port [the port on which the server is running not on the exposed port]
My New DB URL :
spring.datasource.url=jdbc:mysql://local-mysql:3306/dockermysql

Connection refused when building and connecting from spring boot container to keycloak container

I have built two docker containers, spring boot container and keycloak containers. When I run it locally, it works. However, when I build and run both of them in container, it fails and shows errors.
Spring boot error
I got an error when running spring boot in containers

spring boot application did not start on raspberry pi

I don't know why I can't start the java spring boot application on my raspberry pi 4. On the same raspberry runs the Postgres DB in a docker container. The log messages outputs a db connection error, but I don't not what can be the issue or how I can fix this.
The application works fine on my local machine (MacBook) and can connect to the db without errors.

I would start by just trying to connect to the DB with psql.
See whether the port was bound(-p 5432:5432).
I would also recommend creating a container from your application in order to make the database private. Create a network and add the DB and your application in it so that your application is the only thing that has access to it. bear in mind that the url of the DB will change to the name or alias of the container. You can read more about that in Docker compose guides. Then bind the 8081 port of your application to the 8081 port of the raspberry. Thus exposing it so you can use your application.
In that way you will not have to manually manage the java versions on your raspberry but rather in the docker image of your application.

Running Acrarium by docker-compose.yaml causes HikariPool-1 - Exception during pool initialization

I'm trying to run Acrarium on my local Debian 10 machine - just to test it - by running the docker-compose up command with this compose file:
version: '3.7'
services:
database:
image: mysql
container_name: database
environment:
MYSQL_ROOT_PASSWORD: 4f3g2h1j
MYSQL_DATABASE: acrariumdb
MYSQL_USER: acrariumuser
MYSQL_PASSWORD: a1b2c3d4
MYSQL_ROOT_HOST: '%'
expose:
- '3306'
volumes:
- 'acrarium_data:/var/lib/mysql'
acrarium:
image: 'f43nd1r/acrarium:latest'
container_name: acrarium
depends_on:
- database
ports:
- '8080:8080'
environment:
SPRING_DATASOURCE_URL: jdbc:mysql://database:3306/acrariumdb?useSSL=false&allowPublicKeyRetrieval=true&useLegacyDatetimeCode=false&serverTimezone=UTC
SPRING_DATASOURCE_USERNAME: acrariumuser
SPRING_DATASOURCE_PASSWORD: a1b2c3d4
SPRING_DATASOURCE_PLATFORM: org.hibernate.dialect.MySQL57Dialect
SPRING_JPA_DATABASE-PLATFORM: org.hibernate.dialect.MySQL57Dialect
volumes:
acrarium_data: null
The database runs successfully, but when it comes to run acrarium, I'm getting this error in terminal:
HikariPool-1 - Exception during pool initialization.
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.
In docker-compose everything seems OK and googling didn't give any new parameter or value to use in compose file. Have you any idea what I missed here? Thanks in advance.
P.S. Here is terminal's full output when I run docker-compose up:

database issue during spring microservices

I am creating 2 microservices using springboot and xml. I am using spring data JPA for database related things. so I have updated these db details in application.properties file.
I have 2 service. Product service and coupon service.
coupon service is working fine. below are the application.properties details
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password=mahima#123
this is perfectly working fine and i can access api from postman.
But same details except port number I am mentioning for product service and it is throwing eception. same db details, user ,password etc.
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.user=root
spring.datasource.password=mahima#123
server.port=9090
I have given 9090 port because in 8080 coupon service is running. but this api is throwing exception.

Quick question, since you said that it's the same base and etc... shouldn't be:
spring.datasource.username=root
Instead of
spring.datasource.user=root
?
I'm asking because in the logs, it shows no user trying to use in authentication

Your server is up but the datasource cannot connect due to an incorrect credential being passed (wrong property). Consequently, a MySQL exception gets your application killed.
spring.datasource.username=root
If the above property is not set, Spring defaults to an empty username. There's no user with an empty name and hence the error.
