I have a problem with the docker, when running the command docker-compose up -d --build 3 containers app, database, api are created within the application innovation, however when accessing the docker terminal in the api container I get this error`` this is my docker-compose.yaml:

My entrypoint.sh from api:
#!/bin/bash
yarn
yarn develop
In my case, I resolved it by changing the line endings from CRLF to LF for the entrypoint.sh file
Edit
In Notepad++ on the bottom panel on to the Right, right-click on the area Windows (CR LF) and select UNIX (LF) this should replace all CRLFs with LFs.
This error may also occur when starting an image built on a 64-bit x86 agent but running on a 64-bit Arm container host.
For me the line endings were already LF, I had removed all the images and rebuilt them but before building, I found I was missing the shebang -
#!/bin/bash
I just added that and rebuilt the container and found it working.
Same problem, resolved it as Thyi by changing the line endings. Also had to rebuild the image before the change took effect.

After some months of development I got to a point where it is better to dockerize my MERN application. I managed to create .yaml file and everything is working OK but the problem is that I already have big amount of data that is collected. I want to be able to mount this data to container but I don't know how to do it. Read a lot of stuff but still my data is not appearing after composing the applications. Here is how my docker-compose.yaml file looks-like:
version: '3.9'
services:
#MongoDB Service
mongo_db:
container_name: db_container
image: mongo:latest
restart: always
ports:
- 2717:27017
volumes:
- /mnt/c/temp/mongo/db:/data/db
#Node API Service
api:
build: .
ports:
- 4001:4001
environment:
PORT: 4001
MONGODB_URI: mongodb://db_container:27017
DB_NAME: project-system
depends_on:
- mongo_db
volumes:
mongo_db:
As you can see in this row:
volumes:
- /mnt/c/temp/mongo/db:/data/db
I am trying to point the path from my C:\ drive but this doesn't work. I also tried the same row in:
volumes:
mongo_db:
(the bottom of file) but again without success. Basically my existing DB is on
C:\data\db
How can I point this to be the source of MongoDB service?
First, you need to create the dump from local MongoDB and copy those files to docker MongoDB. You can use these commands to create:
mongodump --uri 'mongodb://localhost:27017/yourdatabase' --archive=<your file> --gzip
mongorestore --uri 'mongodb://remotehost:27017/yourdatabase' --archive=<your file> --gzip
You should be able to access the docker from local host.
Note: Reference this answer if you don't get it correct.
You can do these changes on the path you are mounting to make data persistent. Create a new folder C:/data/docker_mongo to make data persistent.

I'm trying to migrate project from mysql to postgres using docker and docker compose file.
I'm connected to Linux server remotely .

docker-compose ps :
I can't start pgadmin :
Your compose file seems okay to me, I use different ports, but my set-up is quite close to yours.
The error message recommends "check the proxy and firewall" (vérifer le proxy et le pare-feu) ... did you check it? I would use netcat:
nc -v -z RemoteHost Port
At least this could result in a helpful error message.
I am currently facing a problem with docker, docker-compose, and postgres that is driving me insane. I have updated my docker-compose with a new postgres password and I have updated my sqlalchemy create_all method with a new table model. But none of these changes are taking affect.
When I go to login to the database container it is still using the old password and the table columns have not been updated. I have run all the docker functions I can think of to no avail
docker-compose down --volumes
docker rmi $(docker images -a -q)
docker system prune -a
docker-compose build --no-cache
After running these commands I do verify that the docker image is gone. I have no images or containers living on my machine but the new postgres image still always is created using the previous password. Below is my docker-compose (I am aware that passwords in docker-compose files is a bad idea, this is a personal project and I intend to change it to pull a secret from KMS down the road)

The password commented out under POSTGRES_DB: rebindme is the one that it is still using somehow. I can post more code or whatever else is needed, just let me know. Thanks in advance for your help!
The answer ended up being that the images were still existing. The below command did not actually remove all containers just unused ones:
docker system prune -a
I did go ahead and delete the postgres data as Pooya recommended though I am not sure that was necessary as I had already done that which I forgot to mention. The real solution for me was:
docker image ls
docker rmi rebindme-client:latest
docker rmi rebindme-api:latest
Then finally the new config for postgres took.
Because you mount volume manually (Host volumes) and when using docker-compose down --volumes actually docker doesn't remove volume. If you don't need to volume and you want to remove that you have to delete this folder (It depends on the operation system) and then run docker-compose
Command docker-compose down -v just remove below volumes type:
Named volumes
Anonymous volumes
# Linux operation system
rm -rf ./postgres-data
docker-compose build --no-cache
I've created two basic MEAN stack apps with a common database (mongo db). I've also built docker for these apps.
Problem:
When i start a mean stack container(example-app-1) using
docker-compose up -d --build
The container runs smoothly and I'm also able to hit the container and view my page locally.
When i try to start another mean stack container(example-app-2) using
docker-compose up -d --build
my previous container is stopped and the current container works without any flaw.
Required:
I want both these containers to run simultaneously using a shared database. I need help in achieving this.

docker-compose will create containers named project_service. The project, by default, comes from the last component of the directory. So when you start the second docker-compose, it will stop the containers with those names, and start new ones.
Either move these two docker-compose files to separate directories so the container names are different, or run docker-compose with --project-name flag containing separate project names so the containers can be started with different names.
I would like to know if it's possible to use my docker container name as host instead of the IP.
Let me explain, here's my docker-compose file :
version : "3"
services:
pandacola-logger:
build: ./
networks:
- logger_db
volumes:
- "./:/app"
ports:
- 8060:8060
- 10060:10060
command: npm run dev
logger-mysql:
image: mysql
networks:
- logger_db
command: --default-authentication-plugin=mysql_native_password
environment:
MYSQL_ROOT_PASSWORD: Carotte1988-
MYSQL_DATABASE: logger
MYSQL_USER: logger-user
MYSQL_PASSWORD: PandaCola-
ports:
- 3306:3306
adminer:
networks:
- logger_db
image: adminer
restart: always
ports:
- 8090:8090
networks:
logger_db: {}
Sorry the intentation is a bit messy
I would like to set the name of my logger-mysql in a the .env file of my webservice (the pandacola-logger) instead of his IP adress
here's the .env file
HOST=0.0.0.0
PORT=8060
NODE_ENV=development
APP_NAME=AdonisJs
APP_URL=http://${HOST}:${PORT}
CACHE_VIEWS=false
APP_KEY=Qs1GxZrmQf18YZ9V42FWUUnnxLfPetca
DB_CONNECTION=mysql
DB_HOST=0.0.0.0 <---- here's where I want to use my container's name
DB_PORT=3306
DB_USER=logger-user
DB_PASSWORD=PandaCola-
DB_DATABASE=logger
HASH_DRIVER=bcrypt
If you can tell me first, if it's possible, and then, how to do it, it would be lovely.
By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.
