Why my spring boot Dockerfile can't connect to AWS RDS?

I am creating a spring boot Api. that Api uses a remote database (RDS). When I run it in my machine the app can connect normally to datasource, but when I build a Docker image and run it can't connect.
My Dockerfile:
FROM openjdk:11-jre-slim
RUN groupadd -r fps && useradd --no-log-init -r -g fps flavio
USER flavio
ARG DEPENDENCY=target/dependency
COPY ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY ${DEPENDENCY}/META-INF app/META-INF
COPY ${DEPENDENCY}/BOOT-INF/classes /app
ENTRYPOINT ["java","-cp","app:app/lib/*","com.fps.app.FpsApplication"]
My application.properties:
server.port=8080

spring.datasource.username=my_username
spring.datasource.password=my_pwd

Bean Creation Exception, Entity Manager Factory error

I'm going to run eatgoAdminApiApplication and it works.
but, when I input application.yml then it doesn't work.
I tried many things after I searched for this problem and all didn't work.
Unfortunately, error messages were too long, so I cut some of them out.

The error message says
org.h2.jdbc.JdbcSQLInvalidAuthorizationSpecException: Wrong user name or password [28000-200]
Add username and password to your data source configuration.
Precise JDBC driver and hibernate dialect also.
spring:
datasource:

jpa:

If you are working in a real application, use a database serve (Mysql, Postgresql...)
H2 is a file or a memory database, it cannot handle transactions :-).

Found the issue. order is a reserved word in MySQL. Changed the table name to orders and things started working.

#Nital you are right, but you can use Mysql reserved word also as table name.
Using backtick character (Manually escaping)
You can escape a given database object qualifier using the backtick character.
#Entity
#javax.persistence.Table(name = "`order`")
public class Order {
...
}
Or
Using globally_quoted_identifiers property (Automatically escaping)
Another option is to set the hibernate.globally_quoted_identifiers property to true in the configuration file. Then all database identifiers will be quoted.
hibernate.globally_quoted_identifiers=true

This reads like having nothing to do with Spring Boot, but the wrong username/password combination.
Have you tried logging in to your MySQL Database with said credentials? With MySQL client or workbench?

Please check if username and password are wrong and check the grant of user.
Take a look at here: Spring Boot MySql Access denied for user 'root'#'localhost'

i got it, you have an extra white space at the end of your pass(root ). delete it and it works
spring.datasource.password=root
and another thing that you should notice is that "com.mysql.jdbc.Driver" is deprecated, use this"com.mysql.cj.jdbc.Driver"

Unable to connect to MySQL database using springboot?

I generated a few tables in MySQL workbench and connected them as a datasource in Intellij. From there, I auto-generated the entity-classes using the persistence tools offered by Intellij, everything is looking good. I'm not sure what is happening.. The big stack trace is posted below.
The main thing that sticks out is an error in the MySQL syntax, but I have specified the dialect and this is all auto-generated.
It looks like I have 3 tables and 2/3 get created. From the picture below, it's the GOALS table that is not getting created.. Interesting..

As your exception logs say that there is a SQL syntax exception near interval ...
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an
error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near 'interval
varchar(255), label_color varchar(255), pledge_amount double
precision,' at line 1
So, the interval is reserved in MySql. Use different column name. You can use #Column over the getter of your interval property.
#Column(name="myinterval")
public String getInterval(){
}
