according to mysql official image you need to add this command to your mysql service in the compose file:
command: --default-authentication-plugin=mysql_native_password
and do not forget to create a new container of your mysql image after adding this command.

I am building a nestjs application where I have used Prisma. I am trying to figure out docker workflow for it. You can see on the code below, Currently, I am first running MySQL container and after healthcheck I am running prisma migrate command from my backend. This process is correct if the volume is removed as it will run migration after the database is ready. But Later I also want to dump a SQL file(insert commands) to the MySQL container once tables are migrated. So here on the below code it runs the dump even before tables are migrated. Can anyone help me on how to dump only after table migration has been created.

I have the following docker-compose.yml and Dockerfile in my Spring Boot app but when I run docker-compose up -d, I get the following error:
"failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount967315702/Dockerfile: no such file or directory"
As I use Windows10, I think I need some tweaks related to the WORKDIR, etc. I have WSL where Docker installed). But even I tried different combinations, I have not managed to fix the problem.

What is my mistake?
Change from MYSQL_HOST=localhost to MYSQL_HOST=mysql
When your app is running inside a docker container, localhost points no longer to your laptop (or server) but to the container itself.
As each service is running in separated containers when one application is trying to access the database service you cannot use localhost. As localhost points to that container, and the database is not installed there.
You should use the container name instead localhost when specificying connection urls.
You can also check Docker Compose network documentation for detailed explanations.
I´m trying to setup two docker container with docker-compose, using this yml:
version: '3.5'
services:
db:
image: mysql:5.7
restart: always
ports:
- 3306:3306
environment:
MYSQL_ROOT_PASSWORD: abc
MYSQL_DATABASE: shopsystem
MYSQL_USER: shoppingsystem
MYSQL_PASSWORD: abc
volumes:

- db_data:/var/lib/mysql
backend:
build:
context: ./nodeserver
dockerfile: Dockerfile
image: node-test
container_name: servernode-1
ports:
- 8084:8082
volumes:
db_data: {}
The test.sql is on the root level like the docker-compose.yml
When I start the docker-compose
docker-compose up
I get the following error:
/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/test.sql
ERROR: Can't initialize batch_readline - may be the input source is a directory or a block device.
I already read some threads about that problem, but I can not solved it.
I clean the volumes with the following command:
docker-compose down -v
I`m using Windows with dockertoolbox to run docker-compose.
Can someone help me?
ERROR: Can't initialize batch_readline - may be the input source is a directory or a block device.
your should to map volume as directory
and put test.sql file in there
volumes:
- myvolumes:/docker-entrypoint-initdb.d
- db_data:/var/lib/mysql
or option 2 (if you want just a single file )
version: "3.2"

Trying to get a rails app running using docker-compose. I run docker-compose build and it completes with no errors. I then run docker-compose up and both of the containers start. Then I run docker-compose run web rake db:create db:migrate and run into an error:

New to docker so not even sure if I am issuing the commands correctly. I need to create and seed the database and have the app container connect to it. I think the issue is related to it trying to connect via localhost, but even when I changed the host to db I still got the same results. Any help would be greatly appreciated.

In detail:
First of all your docker-compose-file is kinda misconfigured.
Therefore I will do a small instruction on docker-compose.yml-files before heading over to your question.
The links:-thing is a legacy feature of docker which you should strictly avoid:
https://docs.docker.com/compose/compose-file/#links
Moreover, it is not even required when you're working with docker-compose
Also, you're using expose: and ports: when defining your database-service.
The ports-key is opening up a port on your host-machine and forwards it to your docker-service:
https://docs.docker.com/compose/compose-file/#ports
Using ports-key on database-definitions makes your database accessible to the www - which is not what you want in most cases.
The expose-key opens the port locally, in the created docker network.
https://docs.docker.com/compose/compose-file/#expose
This is what we want for databases.
Editing your docker-compose.yml-file results in the following:
version: '3.3'
services:
db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: 'online_community_development'
MYSQL_ROOT_PASSWORD: '******'
MYSQL_HOST: 'localhost'
expose:
# Opens port 3306 on the container
- '3306'
# Where our data will be persisted
volumes:
- 'my-db:/var/lib/mysql'
container_name: datab
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
volumes:
- web-app:/myapp
ports:
- "3000:3000"
depends_on:
- db
restart: always
volumes:
my-db: {}
web-app: {}
Getting back to your primary problem:
rake aborted! Mysql2::Error::ConnectionError: Can't connect to MySQL server on '127.0.0.1' (111 "Connection refused")
It looks like rake expects the database to be available at localhost - therefore I think that the cause of this issue is a misconfiguration.
Unfortunately I'm not very familiar with rake but nevertheless your database.yaml looks correct.
I did some research and came across this post:
Rake tasks seem to ignore database.yml configuration
Maybe you could try to set the environment-variable DATABASE_URL in your docker-compose-file: DATABASE_URL=mysql://db
I'd also recommend to set the correct context-environment-variable: RAILS_ENV=development
When you do alle these changes you should come up with the following docker-compose.yml:
version: '3.3'
services:
db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: 'online_community_development'
MYSQL_ROOT_PASSWORD: '******'
MYSQL_HOST: 'localhost'
expose:
# Opens port 3306 on the container
- '3306'
# Where our data will be persisted
volumes:
- 'my-db:/var/lib/mysql'
container_name: datab
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
environment:
DATABASE_URL: 'mysql2://db'
RAILS_ENV: 'development'
volumes:
- web-app:/myapp
ports:
- "3000:3000"
depends_on:
- db
restart: always
volumes:
my-db: {}
web-app: {}
Hope this helps.

your db seems to be configured to listen on localhost only. Unfortunately this will not work since your app is technically another network host (container) within the compose network. Try making your db listen on all network interfaces.
