I need to create a new external PostgreSQL database to replace the default H2 database that Keycloak uses by default. When I create a database using the keycloak file, the database is not created when running Keycloak:
Caused by: org.postgresql.util.PSQLException: FATAL: database "sso" does not exist

When I am giving the application database as the value I am able to connect to the database. But my intention is to connect to a different database:
cat Keycloak
CREATE DATABASE IF NOT EXISTS sso;
docker-compose.yaml
data-keycloak:

I created a docker compose file to run a spring-boot application (2.5.7) and a MS SQL Server:
version: '3.8'
services:
db:
ports:
- 1434:1433
build: ./db
api:
depends_on:
- db
build: ./mdm-web-api
restart: on-failure
env_file: ./.env
ports:
- $SPRING_LOCAL_PORT:$SPRING_DOCKER_PORT
environment:
- SPRING_DATASOURCE_URL=jdbc:sqlserver://db:1434;databaseName=dwh-demo;encrypt=true;logingTimeout=30
stdin_open: true
tty: true
I defined a Dockerfile for the mssql in the folder 'db' and successfully tested the SQL server alone.
I added my spring-boot application, which I also tested separately.
I have an application.properties file as follow (I replace sensible values):
logging.level.root=INFO
spring.datasource.username=<my-db-user>
spring.datasource.password=<my-ultra-strong-pw>
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.properties.hibernate.default_schema:entity_reference
spring.jpa.hibernate.use-new-id-generator-mappings=false
spring.jpa.generate-ddl=false
spring.jpa.show-sql=true
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.data.rest.basePath=/api
springdoc.api-docs.path=/api-docs
I just added the spring.datasource.url properties in the docker-compose.yml to be able to point to the database server using the service name:
environment:
- SPRING_DATASOURCE_URL=jdbc:sqlserver://db:1434;databaseName=dwh-demo;encrypt=true;logingTimeout=30
It seems like the SPRING_DATASOURCE_URL value is completely ignored and I'm getting the following error:
Failed to determine suitable jdbc url
It shouldn't be a problem to use both places to add configuration, but maybe I'm wrong.
What could be the problem and which alternative do I have?
Additional details:
java openjdk 19
maven 3.8.5

I am trying to connect to a mysql database on my host using a docker container (so I can use it in other containers).
I would like to do it this way, because I cannot connect to the database from a docker container -> throws Connection refused because the IP is not allowed.
I tried mounting the sock file using following compose:
version: '3'
services:
mysql:
image: mariadb:10.3
volumes:
- /var/run/mysqld/mysqld.sock:/var/run/mysqld/mysqld.sock
networks:
- database
networks:
database:
external: true
but it's failing on (even though the host database already contains many databases):
2022-06-07 20:14:46+00:00 [ERROR] [Entrypoint]: Database is uninitialized and password option is not specified
You need to specify one of MARIADB_ROOT_PASSWORD, MARIADB_ALLOW_EMPTY_ROOT_PASSWORD and MARIADB_RANDOM_ROOT_PASSWORD,
and when I added the volume: - /var/lib/mysql:/var/lib/mysql, I am getting a Connection refused error (as if I was connecting to it normally and not via unix)
Here you go, consider checking the documentation before asking thoses types of questions

GO
CREATE USER $(MSSQL_USER) FOR LOGIN $(MSSQL_USER);
GO
ALTER SERVER ROLE sysadmin ADD MEMBER [$(MSSQL_USER)];
GO
Here is the running container:
I am trying to connect to the database through the Visual Studio Code extension:
Using this connection string: Server=http://localhost:1433/;Database=master;User Id=sa;Password=Passw#rd;
I am getting the error:
mssql: Error: Unable to connect using the connection information provided. Retry profile creation?
What am I doing wrong here?
It fails to connect to the SQL Server container, even if the backend is running in local and the database in docker.
I tested with Azure SQL and everything worked perfectly.
Error(s):
After docker-compose up, and try to add element to the list:

Connection string in the appsettings.json
"ConnectionStrings": {
"DefaultConnection": "Server=sqlserver;Database=AsdDB;user id=sa;password=ASDFGHJ12345;"
},
In the connection string, the Server had to be passed the following value:
Server=host.docker.internal;Database=AsdDB;user id=sa;password=ASDFGHJ12345%;
So now it works, it took 2 days of messing with it, but after I posted the question, I found the answer.

Most likely its due to low php memory as well as file permission system. I recommend to contact hosting to fix this issue and if not possible then you can increase php memory and reset file permission to have it solved.
