I have set an Oracle docker image (https://github.com/oracle/docker-images/tree/main/OracleDatabase/SingleInstance/dockerfiles) which by default is running on port 1521.
I would like to change the port in the Image to 1531.
I know that in the docker-compose I can set "1531:1521" BUT the other container still searching for port 1521 in the created network.
I tried to modify the port referenced in the Dockerfile of the version I want to use (19.3.0) and also in the createDB.sh but when I try to connect with the SID it fails, the listener is not working as expected.
Anybody already succeeded?
Update 1:
Here is the error message when I try to connect to the database after I changed the port.
SQL> CONNECT sys/HyperSecuredPassword#ORCLCDB AS sysdba; ERROR: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Update 2:
I have the following docker-compose.yaml to set up the other containers for my project.

If you want to change the port used WITHIN the container (I think this is the question), you could try building a new image after modifying the conf file, e.g. (for the 18c image). The other images hard code the 1521 port in various files in that repo depending on the oracle version you are using, so those would have to be changed prior to building the image.
I have been using this image: container-registry.oracle.com/database/express:latest. This is version 18c and it has a conf file within the image located at /etc/sysconfig/oracle-xe-18c.conf, I would just build a new Dockerfile and overwrite that file with a new one that has the port you require. Or, you could extract the entire contents of that directory, dump it to a host directory, modify the file as needed, and map a volume to etc/sysconfig (make sure the permissions are correct). This way you could tweak the file from the host. It might be possible to set the variable in that conf file from an environment variable within a docker-compose.yaml file or on the docker command line. This variable is named LISTENER_PORT. Some of the variables in these scripts are defined locally and do not pull their values from environment variable though.

I'm trying to deploy my java Spring boot application into windows docker container(wsl support is enabled)
When i tried running my yml file the java server is up and running.
But I've a functionality where i need to access the files From Local Disk C & D (host machine)
When ever I tried to access a file with path like "D:\Folder\example.pdf" I'm getting File not found exception.
Here is my docker-compose.yml file
version: "3"
services:
java_spring_backend:
image: java_spring_backend:latest
restart: unless-stopped
container_name: java_spring_backend
build: ./server/
ports:
- "8081:8080"
You must mount the host folder to your docker container.
ex.
version: "3"
services:
java_spring_backend:
image: java_spring_backend:latest
restart: unless-stopped
container_name: java_spring_backend
build: ./server/
volumes:
- "./Folder:/FolderInsideDocker"
Or as absolut path ex. for wsl: /mnt/c/Folder:/FolderInsideDocker

I’m trying to run Sonarqube in a Docker container on a Centos 7 server using docker-compose. Everything works as expected using named volumes as configured in this docker-compose.yml file:
version: "3"
services:
sonarqube:
image: sonarqube
ports:
- "9000:9000"
networks:
- sonarnet
environment:
- sonar.jdbc.url=jdbc:postgresql://db:5432/sonar
volumes:
- sonarqube_conf:/opt/sonarqube/conf
- sonarqube_data:/opt/sonarqube/data
- sonarqube_extensions:/opt/sonarqube/extensions
- sonarqube_bundled_plugins:/opt/sonarqube/lib/bundled-plugins
db:
image: postgres
networks:
- sonarnet
environment:
- POSTGRES_USER=sonar
- POSTGRES_PASSWORD=sonar
volumes:
- postgresql:/var/lib/postgresql
- postgresql_data:/var/lib/postgresql/data
networks:
sonarnet:
driver: bridge
volumes:
sonarqube_conf:
sonarqube_data:
sonarqube_extensions:
sonarqube_bundled_plugins:
postgresql:
postgresql_data:
However, my /var/lib/docker/volumes directory is not large enough to house the named volumes. So, I changed the docker-compose.yml file to use bind mount volumes as shown below.
version: "3"
services:
sonarqube:
image: sonarqube
ports:
- "9000:9000"
networks:
- sonarnet
environment:
- sonar.jdbc.url=jdbc:postgresql://db:5432/sonar
volumes:
- /data/sonarqube/conf:/opt/sonarqube/conf
- /data/sonarqube/data:/opt/sonarqube/data
- /data/sonarqube/extensions:/opt/sonarqube/extensions
- /data/sonarqube/bundled_plugins:/opt/sonarqube/lib/bundled-plugins
db:
image: postgres
networks:
- sonarnet
environment:
- POSTGRES_USER=sonar
- POSTGRES_PASSWORD=sonar
volumes:
- /data/postgresql:/var/lib/postgresql
- /data/postgresql_data:/var/lib/postgresql/data
networks:
sonarnet:
driver: bridge
However, after running docker-compose up -d, the app starts up but none of the bind mount volumes are written to. As a result, the Sonarqube plugins are not loaded and the sonar postgreSQL database is not initialized. I thought it may be a selinux issue, but I temporarily disabled it with no success. I’m unsure what to look at next.
I think my answer from "How to persist configuration & analytics across container invocations in Sonarqube docker image" would help you as well.
For good measure I have also pasted it in here:
.....
Notice this line SONARQUBE_HOME in the Dockerfile for the docker-sonarqube image. We can control this environment variable.
When using docker run. Simply do:
txt
docker run -d \
...
...
-e SONARQUBE_HOME=/sonarqube-data
-v /PERSISTENT_DISK/sonarqubeVolume:/sonarqube-data
This will make Sonarqube create the conf, data and so forth folders and store data therein. As needed.
Or with Kubernetes. In your deployment YAML file. Do:
txt
...
...
env:
- name: SONARQUBE_HOME
value: /sonarqube-data
...
...
volumeMounts:
- name: app-volume
mountPath: /sonarqube-data
And the name in the volumeMounts property points to a volume in the volumes section of the Kubernetes deployment YAML file.
This again will make Sonarqube use the /sonarqube-data mountPath for creating extenions, conf and so forth folders, then save data therein.
And voila your Sonarqube data is thereby persisted.
I hope this will help others.
N.B. Notice that the YAML and Docker run examples are not exhaustive. They focus on the issue of persisting Sonarqube data.
Try it out BobC and let me know.
Have a great day.
The below code will help you in a single command I hope so.
Create a new docker-compose file named as docker-compose.yaml,
version: "3"
services:
sonarqube:
image: sonarqube:8.2-community
depends_on:
- db
ports:
- "9000:9000"
networks:
- sonarqubenet
environment:
SONAR_JDBC_URL: jdbc:postgresql://db:5432/sonarqube
SONAR_JDBC_USERNAME: sonar
SONAR_JDBC_PASSWORD: sonar
volumes:
- sonarqube_data:/opt/sonarqube/data
- sonarqube_extensions:/opt/sonarqube/extensions
- sonarqube_logs:/opt/sonarqube/logs
- sonarqube_temp:/opt/sonarqube/temp
restart: on-failure
container_name: sonarqube
db:
image: postgres
networks:
- sonarqubenet
environment:
POSTGRES_USER: sonar
POSTGRES_PASSWORD: sonar
volumes:
- postgresql:/var/lib/postgresql
- postgresql_data:/var/lib/postgresql/data
restart: on-failure
container_name: postgresql
networks:
sonarqubenet:
driver: bridge
volumes:
sonarqube_data:
sonarqube_extensions:
sonarqube_logs:
sonarqube_temp:
postgresql:
postgresql_data:
Then, execute the command,
$ docker-compose up -d
$ docker container ps
Sounds like the container is running and, as you mentioned, Sonarqube starts-up. When it starts, is it showing that it's using the H2 in memory db? After running docker-compose up -d, use docker logs -f <container_name> to see what's happening on Sonarqube startup.
To simplify viewing your logs with a known name, I suggest you also add a container name to your Sonarqube service. For example, container_name: sonarqube.
Also, while I know the plan is to deprecate the use of environment variables for the username, password and jdbc connection, I've had better luck in docker-compose using environment variables rather than the corresponding property value. For the connection string, try: SONARQUBE_JDBC_URL: jdbc:postgresql://db/sonar without specifying the default port for postgres.
I have a Java Spring Boot app which works with a Postgres database. I want to use Docker for both of them. I initially put just the Postgres in Docker, and I had a docker-compose.yml file defined like this:
version: '2'
services:
db:
container_name: sample_db
image: postgres:9.5
volumes:
- sample_db:/var/lib/postgresql/data
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
- PGDATA=/var/lib/postgresql/data/pgdata
ports:
- 5432:5432
volumes:
sample_db: {}
Then, when I issued the commands sudo dockerd and sudo docker-compose -f docker-compose.yml up, it was starting the database. I could connect using pgAdmin for example, by using localhost as server and port 5432. Then, in my Spring Boot app, inside the application.properties file I defined the following properties.
spring.datasource.url=jdbc:postgresql://localhost:5432/sample
spring.datasource.username=sample
spring.datasource.password=sample
spring.jpa.generate-ddl=true
At this point I could run my Spring Boot app locally through Spring Suite, and it all was working fine. Then, I wanted to also add my Spring Boot app as Docker image. I first of all created a Dockerfile in my project directory, which looks like this:
FROM java:8
EXPOSE 8080
ADD /target/manager.jar manager.jar
ENTRYPOINT ["java","-jar","manager.jar"]
Then, I entered to the directory of the project issued mvn clean followed by mvn install. Next, issued docker build -f Dockerfile -t manager . followed by docker tag 9c6b1e3f1d5e myuser/manager:latest (the id is correct). Finally, I edited my existing docker-compose.yml file to look like this:
version: '2'
services:
web:
image: myuser/manager:latest
ports:
- 8080:8080
depends_on:
- db
db:
container_name: sample_db
image: postgres:9.5
volumes:
- sample_db:/var/lib/postgresql/data
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
- PGDATA=/var/lib/postgresql/data/pgdata
ports:
- 5432:5432
volumes:
sample_db: {}
But, now if I issue sudo docker-compose -f docker-compose.yml up command, the database again starts correctly, but I get errors and exit code 1 for the web app part. The problem is the connection string. I believe I have to change it to something else, but I don't know what it should be. I get the following error messages:
web_1 | 2017-06-27 22:11:54.418 ERROR 1 --- [ main] o.a.tomcat.jdbc.pool.ConnectionPool : Unable to create initial connections of pool.
web_1 |
web_1 | org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
Any ideas?
Each container has its own network interface with its own localhost. So change how Java points to Postgres:
spring.datasource.url=jdbc:postgresql://localhost:5432/sample
To:
spring.datasource.url=jdbc:postgresql://db:5432/sample
db will resolve to the proper Postgres IP.
Bonus. With docker-compose you don't need to build your image by hand. So change:
web:
image: myuser/manager:latest
To:
web:
build: .
I had the same problem and I lost some time to understand and solve this problem:
org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
I show all the properties so that everyone understands.
application.properties:
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL82Dialect
spring.jpa.hibernate.ddl-auto=update
docker-compose.yml:
version: "3"
services:
springapp:
build: .
container_name: springapp

For start spring application with local database we use url localhost.
For connect to container with database we need change 'localhost' on your database service, in my case 'localhost' to 'db'.
Solution: add SPRING_DATASOURCE_URL environment in docker-compose.yml wich rewrite spring.datasource.url value for connect:
environment:
SPRING_DATASOURCE_URL: jdbc:postgresql://db:5432/testdb
I hope this helps someone save his time.
You can use this.
version: "2"
services:
sample_db-postgresql:
image: postgres:9.5
ports:
- 5432:5432
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
volumes:
- sample_db:/var/lib/postgresql/data
volumes:
sample_db:
You can use ENV variable to change the db address in your docker-compose.
Dockerfile:
FROM java:8
EXPOSE 8080
ENV POSTGRES localhost
ADD /target/manager.jar manager.jar
ENTRYPOINT exec java $JAVA_OPTS -jar manager.jar --spring.datasource.url=jdbc:postgresql://$POSTGRES:5432/sample
docker-compose:
`
container_name: springapp
environment:
- POSTGRES=db`
I am new to this area. I have a docker-compose.yml file which starts Magento & MariaDB dockers container. And here is the script:
version: '2'
services:
mariadb:
image: 'bitnami/mariadb:latest'
environment:
- ALLOW_EMPTY_PASSWORD=yes
volumes:
- 'mariadb_data:/bitnami/mariadb'
magento:

environment:
- ENVIRONMENT=Test3
ports:
- '89:80' #for Test3
volumes:

volumes:

php_data:

I tried to use http://127.0.0.1:89 for the site, and it did happen at beginning (e.g. I could open site with URL: http://127.0.0.1:89 ). However when I view page source I found these style/js still points to http://127.0.0.1 (port 80) one. Also I couldn't access its other page like http://120.0.0.1:89/admin.
Then I google, for example some posts mention I need to change base_url value in "core_config_data" table which I did (https://magento.stackexchange.com/questions/39752/how-do-i-fix-my-base-urls-so-i-can-access-my-magento-site). And I do clear the var/cache folder on both Magento & MariaDB containers, but result is still the same. (I didn't find var/session folder which that link mentions. Maybe a little bit different among Bitnami system and others.)
So how could I try now? And also is there anyway that I could set base_url with correct port to MariaDB at very beginning in my docker-compose.yml file?
P.S. Everything works fine if using default port 80.
Thanks a lot!
You can indicate the port where Apache should be listening in the docker-compose.yml file in this way:
version: '2'
services:
mariadb:
image: 'bitnami/mariadb:latest'
environment:
- ALLOW_EMPTY_PASSWORD=yes
volumes:
- 'mariadb_data:/bitnami/mariadb'
magento:
image: 'bitnami/magento:latest'
ports:
- '89:89'
- '443:443'
environment:
- APACHE_HTTP_PORT=89
volumes:
- 'magento_data:/bitnami/magento'
- 'php_data:/bitnami/php'
- 'apache_data:/bitnami/apache'
depends_on:
- mariadb
volumes:
mariadb_data:
driver: local
magento_data:
driver: local
apache_data:
driver: local
php_data:
driver: local
Please, note the use of the APACHE_HTTP_PORT environment variable on the Magento container. Also, note that the port forwarding should be 89:89 in this case.
Take into account that this change should be performed when you launch for the first time the containers. That means that, if you have some volumes already, this method won't work because your configuration will be restored from those volumes. So, ensure that you don't have any volume. You can check it by executing
docker volume ls
and checking that there isn't any volume named
local DATE_apache_data
local DATE_magento_data
local DATE_mariadb_data
Also, you can also delete the volumes executing:
docker-compose down -v
Tl;Dr; Trying to get WordPress docker-compose container to talk to another docker-compose container.
On my Mac I have a WordPress & MySQL container which I have built and configured with a linked MySQL server. In production I plan to use a Google Cloud MySQL storage instance, so plan on removing the MySQL container from the docker-compose file (unlinking it) and then separate shared container I can use from multiple docker containers.
The issue I'm having is that I cant connect the WordPress container to the separate MySQL container. Would anyone be able to shed any light on how I might go about this?
I have tried unsuccessfully to create a network as well as tried creating a fixed IP that the local box has reference to via the /etc/hosts file (my preferred configuration as I can update the file according to ENV)

What you probably want to do is create a shared Docker network for the two containers to use, and point them both to it. You can create a network using docker network create <name>. I will use sharednet as an example below, but you can use any name you like.
Once the network is there, you can point both containers to it. When you're using docker-compose, you would do this at the bottom of your YAML file. This would go at the top level of the file, i.e. all the way to the left, like volumes:.
networks:
default:
external:
name: sharednet
To do the same thing on a normal container (outside compose), you can pass the --network argument.
docker run --network sharednet [ ... ]
