I have a docker-compose.yml file. It works fine in Windows 10 but whenever I try to run that in MacOs it doesnt work especially the shared volume.
Here is the content of my docker-compose.yml file and directory structure
version: '3'
services:
database:
image: mongo
container_name: pcore-database
ports:
- '27017:27017'
node-server:
image: node
container_name: pcore-node-server
volumes:
- ./node-services :/usr/app/node-services
working_dir: /usr/app/node-services
command: npm run dev
ports:
- '3000:3000'
links:
- database
- nginx-server
depends_on:
- database
apache-server:
image: webdevops/php-apache
container_name: pcore-apache-server
working_dir: /app
volumes:
- ./php-services :/app
ports:
- '8000:80'
Check the node-server service and nginx-server
Now when i run command docker-compose up it creates additional directories with same name and throws error.
Check the error and additional directories it created.
I dont know whats going on. Its working fine in windows 10 but in MacOs it creates additional directories and does not share the volumes. Can someone guid me?

I have a problem about running docker-compose.yml in my Spring Boot app.
When I run this command (docker-compose up -d), I got an issue in image part.
I tried to handle with solving this issue but I couldn't do that.
How can I fix it?
Here is my issue shown below.

There are several issues, why it doesn't work.
First thing - your tests aren't set up properly. Application tries to connect to database in the test stage. But during the test stage there is no any running containers yet. You can set it up properly, or remove MainApplicationTests class from the test directory, or by switching off your tests execution, just by adding -Dmaven.test.skip in Dockerfile for the mvnw package command. After it your image will build properly.
Second thing, you need to allow public key retrieval for your application. To do that, you can add allowPublicKeyRetrieval=true to your jdbc url. You can read more about it here: Connection Java - MySQL : Public Key Retrieval is not allowed.
These steps will allow your application to start (at least it will resolve database connectivity problems). But, I have found another issue. You set in your application configuration context-path equal to /api. Also you added #RequestMapping("/api") for your PersonController. And to access the list of persons, you will need to use the following url: http://localhost:8077/api/api/persons. Probably, it is not what you wanted. To fix it, you can remove it from any place.
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 am unsure if the volumes in nginx ok, I think that perhaps I should create a new Dockerfile to copy the files. However, this would increase a lot the size of the project.
When using App Services on azure the development is made assigning a randomly port, that's wgy i have the envsubst instruction in command. I appreciate any other suggestion to make it run this project on Azure
I'm assuming you're trying to persist the storage in your app to a volume. Check out this doc issue. Now I don't think you need
volumes:
- ./:/var/www/
- ./setup/azure/nginx/conf.d/:/etc/nginx/template
but for
volumes:
- uploads:/var/www/simple/public/uploads
- logos:/var/www/simple/public/logos
you can create a storage account, mount it to your linux app plan (it's not available for Windows app plans yet), and mount the relative path /var/www/simple/public/uploads to the file path of the storage container.
There is a service that uses mongodb. But when I restart computer or docker machine, no data is stored in the database.
docker-compose.yml:
version: "3"
Services:
...
mongodb:
restart: always
image: mongo:latest
environment:
- MONGO_DATA_DIR=/dockerdata/db
volumes:
- ./dockerdata/db:/data/db
ports:
- 27017:27017
command: mongod
I tried to do database storage on the host, but it didn't help either:
docker-compose.yml:
version: "3"
Services:
...
mongodb:
restart: always
image: mongo:latest
environment:
- MONGO_DATA_DIR=/c/users/frol/mongodata/db
volumes:
- /c/users/frol/mongodata/db:/data/db
ports:
- 27017:27017
command: mongod
If you make a named volume, docker writes an error:
ERROR: for test_mongodb_1 Cannot create container for service mongodb: fa

Help me, please, I'm a novice. How do I make sure that the database data isn't lost?
You first attempt would work if you just fix a simple typo in your compose file:
version: "3"
services:
...
mongodb:
restart: always
image: mongo:latest
environment:
- MONGO_DATA_DIR=/data/db # changed
volumes:
- ./dockerdata/db:/data/db
ports:
- 27017:27017
command: mongod
But, since /data/db is the default value of MONGO_DATA_DIR, setting it is pretty redundant.
But I'd prefer to use a named volume, that way the data persists but I don't have to see the "ugly" database storage folder:
version: "3"
services:
...
mongodb:
restart: always
image: mongo:latest
volumes:
- mongodata:/data/db
ports:
- 27017:27017
command: mongod
volumes:
mongodata:
Don't set $MONGO_DATA_DIR; leave it at its default of /data/db.
services:
mongodb:
restart: always
image: mongo:latest
# No need to specifically set $MONGO_DATA_DIR
volumes:
- ./dockerdata/db:/data/db
ports:
- 27017:27017
# No need to override command:
Docker containers have a separate filesystem space from the host filesystem. A typical setup for most databases is to have the database storage in a fixed location inside the container; for MongoDB that's the /data/db directory. You can mount a named volume or filesystem path there, but the code inside the container doesn't know the difference.
If you do set environment variables like $MONGO_DATA_DIR, they need to reflect paths inside the container; they can't directly specify host-system paths. (#ruohola's answer works because it changes the container-filesystem path of the bind mount to match the container-filesystem path in the environment variable; the host ./dockerdata and container /dockerdata paths are totally unrelated.)
As you are defining the data dir explicitly, you need to map the same directory in the volume to persist the data
version: "3"
services:
...
mongodb:
restart: always
image: mongo:latest
environment:
- MONGO_DATA_DIR=/data/db #data directory
volumes:
- ./dockerdata/db:/data/db #same data directory which you defined above
ports:
- 27017:27017
command: mongod
