Spring Boot provides default values for some application properties:
spring.rabbitmq.password=guest
spring.rabbitmq.username=guest
In this case, it is only a coincidence.
Change these properties to something else and you will see that the auth will fail.

I'm writing a test app in microservices to learn Spring Boot. I'm done with the app and looking to deploy it on AWS using docker/docker-compose to host each microservices.
I'm unable to connect any of the Spring Boot instances to their Mysql database. I've been stuck on it for a few days and I can't see what's wrong.
Here is my docker-compose.yml

I'm sure it is something small I'm missing or misunderstood, but I can't figure out what.
Edit 1
I ran a couple more tests but still wasn't able to figure out what's wrong.
I commented out everything but the card and card_mysql containers. The spring boot instance throw an exception for every configuration possible (using docker dns name, localhost, shared and network ip), none of them seems to work.
The two containers do communicate, I can ping between them using the dns name.
I'm using docker-desktop with wsl and deploy my containers on a wsl Ubuntu 20.04. I haven't tried on an actual Linux machine.
I've also tried to make the spring boot instance wait for the mysql one using wait-for-it.sh, it does wait correctly but the exception still occurs.
Here is parts of the exception spring boot triggers:
2021-05-16 12:23:48.948 INFO 1 --- [ main] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Starting...

Edit 2
I tried having just one instance of spring boot and mysql and linking them using a network, unfortunately the exception still triggers. The two containers still pings. Here is the docker-compose I used for this test:

My service is using RabbitMQ. To work with it, I installed this package https://github.com/vyuldashev/laravel-queue-rabbitmq .
To work with this package, need to configure the config file
'hosts' => [
[
'host' => env('RABBITMQ_HOST', '127.0.0.1'),
'port' => env('RABBITMQ_PORT', 5672),
'user' => env('RABBITMQ_USER', 'guest'),
'password' => env('RABBITMQ_PASSWORD', 'guest'),
'vhost' => env('RABBITMQ_VHOST', '/'),
],
],
As you can see, the ip is specified as 127.0.0.1, but my docker container has a dynamic ip, so it is updated every time and I have to manually fix the config

How can I tell the rabbitmq container to connect to the external ip of the app container?
Sorry about the confusion, I somehow mixed up Redis and RabbitMQ. So here is a probably better matching answer:
You can connect to a service on your host from the Docker container even with a changing IP - there is script and a nice answer in this SO post.
Some excerpt:
If you are on Mac or Windows you can set
RABBITMQ_HOST=host.docker.internal
In general more easy I would consider a separate container running RabbitMQ and then using rabbitmq as hostname to connect to.

i m trying to deploy a Spring Server on Docker. The Spring server is connecting to a RabbitMQ Server that runs in another app. I get an error while connecting to the rabbitmq. I added the host in my application.properties, didnt work. Than added to the app-container as environment variable and still doesnt work. I also rebuilded the jar and changed the images version.

spring.rabbitmq.host= rabbitmq
This is the error i get
org.springframework.amqp.AmqpIOException: java.net.UnknownHostException: rabbitmq
The networks configuration was missing for rabbitmq in the dockercompose file:
rabbitmq:

ports:
- "5672:5672" #JMS Port
- "15672:15672" #Management Port - default user:pass = guest:guest

Another solution suggested by #david-maze is to remove all networks
I'm using an application hosted on a docker container.
This application executes bash scripts / instructions to send mails.
I made another container which executes Postfix as a SMTP Relay.
I want to send mails from my application container by using a bash script using my Postfix container as a relay.
I tried to connect with SSH from my application container to my Postfix container. But that doesn't seem to work.
How can i make it so a script executed in my application container can use my Postfix relay while not allowing anything outside of the docker network, or even better, to only allow some containers, to send mails from this relay.

{a quick response, because I "cicle" in my work ... and I'm taking 10 minutes of clear my mint, I hope it serves you}
Are you using "docker-compose" ?, could you give an example of your YML file? (a little more context)
[you can not connect to by ssh to a container unless you have "supervisor" installed,which I do not recommend at all.]
from what I see, you only need to make private networks; You could use this:
https://docs.docker.com/compose/networking/
to hide everything, I also recommend using a load balancer / Inverse Proxy like TRAEFIK (if they have access to port 80 or 443 in some clear way this ...)
so you only expose 1/2 port(s) (80 + 443 for example) and everything else is protected by your reverse proxy
Watch as I separate the networks as you need the different containers.
bash have access to db and smtp
db does not have access smtp neither nginx
nginx have access to bash
nginx have access to proxy network to expose 80 and 443
no other container is exposed to the outside more than nginx

I am attempting to host a Spring Cloud application in Docker containers.The underlying exception is as follows:
search_1 | Caused by: java.lang.IllegalStateException: Invalid URL: config:8888
I understand the reason is because of the URL specified in my config server.
spring.application.name=inventory-client
#spring.cloud.config.uri=http://localhost:8888
spring.cloud.config.uri=config:8888
On my development machine, I am able to use localhost. However, based on a past question (relating to connecting to my database), I learned that localhost is not appropriate in containers. For my database, I was able to use the following:
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=false
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.datasource.url=jdbc:postgresql://db:5432/leisurely_diversion
#spring.datasource.url=jdbc:postgresql://localhost:5000/leisurely_diversion
spring.datasource.driver-class-name=org.postgresql.Driver
but this obviously did not work as expected for the configuration server.

Both services are running under the same user defined network; how I allow the services to find the configuration service?
Thanks.
