Im currently doing an app using Prisma and a Postgres database and I can't connect my database to Navicat. I'm a beginner with docker and dont understand completely how services work. My current docker-compose.yml is
version: '3'
services:
prisma:
image: prismagraphql/prisma:1.8
restart: always
ports:
- "4466:4466"
environment:
PRISMA_CONFIG: |
port: 4466
# uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
# managementApiSecret: my-secret
databases:
default:
connector: postgres
host: postgres
port: 5432
user: prisma
password: prisma
migrations: true
postgres:
image: postgres
restart: always
environment:
POSTGRES_USER: prisma
POSTGRES_PASSWORD: prisma
volumes:
- postgres:/var/lib/postgresql/data
volumes:
postgres:
And what I tried on Navicat is this, what seems to me correct but it would appear that no.
Thank you for you help !
You need to use port mapping using the ports property for your postgres container:
version: '3'
services:
prisma:
image: prismagraphql/prisma:1.8
restart: always
ports:
- "4466:4466"
environment:
PRISMA_CONFIG: |
port: 4466
# uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
# managementApiSecret: my-secret
databases:
default:
connector: postgres
host: postgres
port: 5432
user: prisma
password: prisma
migrations: true
postgres:
image: postgres
restart: always
ports:
- "5432:5432"
environment:
POSTGRES_USER: prisma
POSTGRES_PASSWORD: prisma
volumes:
- postgres:/var/lib/postgresql/data
volumes:
postgres:
Then you should be able to connect to localhost:5432 with a Postgres client, like Navicat.

I want to connect redash to MySQL Server. I added MYSQL_TCP_PORT for server to use TCP connection, not default UNIX socket (to avoid mysqld.sock error). If I go to mysql container and mysql -p - I can open mysql shell. But If I test connection in redash - it will return (2006, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)").
Here is my docker-compose file:
# This configuration file is for the **development** setup.

As I see - redash is connecting via unix socket - not TCP connection (otherwise there will no mysqld.sock err). I don't know - what I should fix in docker-compose or somewhere else to make it connect properly. Any suggestions? If you need me to provide more info - ask me please
OK so I am trying to deploy a Rails app to a docker container (host machine is a mac). I was thinking to deploy in development first to check everything is working.
I have setup a phpmyadmin service and I can connect to the server by typing in server name moviedb_mariamovie_1 with user root and corresponding PW.
But whatever I put into my database.yml for Rails doesn't work: I tried localhost, I tried 127.0.0.1, I tried "mariamovie" and I tried "moviedb_mariamovie_1", and it always says "host not found" when I tried rails db:create (or anything actually that involves the DB).
I am totally confused by this. I read the database section of the docker manuals and I seem to be too stupid for that.
(I have other problems with this but one after the other :)
docker-compose.yml:
version: "3.7"
services:
moviedb:

You're inside your docker "network". Your database should be accessible from your Rails app (which is inside too) via mariamovie:3306.
At the moment, I'm trying to set up my docker-compose file to run multiple (two) Node.js API's.
The first Node.js server connects fine to the database.
The second Node.js server keeps throwing this error
original: Error: connect ECONNREFUSED 172.29.0.3:3307
So my question is how to run multiple Node.js API's in docker?
This is my docker-compose.yaml:
version: '3.7'
services:
ISAAC-floor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3306:3306"
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-sensor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3307:3307"
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-floor-back-end:
image: jjuless/isaac-floor-back-end
environment:
DB_HOST: ISAAC-floor-database
DB_USER: root
DB_PASSWORD: isaac
DB_DATABASE: isaac
DB_PORT: 3306
DB_DIALECT: mysql
ports:
- "3000:80"
depends_on:
- ISAAC-floor-database
ISAAC-sensor-back-end:
image: jjuless/isaac-sensor-back-end
environment:
DB_HOST: ISAAC-sensor-database
DB_USER: root
DB_PASSWORD: isaac
DB_DATABASE: isaac
DB_PORT: 3307
DB_DIALECT: mysql
ports:
- "3001:80"
depends_on:
- ISAAC-sensor-database
Mysql is always listening on port 3306 in each container, so if you want to have multiple mysql instances in the same host, you will need to map different host ports to the same guest port
Hence you will need to change your docker-compose file as follows
ISAAC-floor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3306:3306" # <-- HOST port same as GUEST port
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-sensor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3307:3306" # <-- Notice here the GUEST port is the same as the first container!
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
I'm working on building docker containers for a Ruby-on-Rails project I'm currently working on, so that I can develop this project using the remote feature of Visual Studio Code. This project should still continue to work without using docker containers, so I cannot make breaking changes to the existing code that would compromise this.
The application server (Rails) needs to connect to a MySQL database that's running in a separate container. The database container is named db, and I can connect from the application container to this container by using the db hostname.
The database.yml config file for rails defines how to connect to the database, but this is where my problem is situated. I don't want to change the host to db instead of localhost as this would mean that regular users (that do not use Docker containers) will no longer be able to connect to the database without changing this file. How can I somehow start or change my docker config so that db is accessible as localhost instead of db inside of the application container?
database.yml:
default: &default
adapter: mysql2
username: ****
password: ****
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: ****
# setup local port forwarding for this to work
host: db
port: 3306
docker-compose.yml:
version: '3.7'
services:
db:
build: ./unipept-db
environment:
MYSQL_ROOT_PASSWORD: ****
MYSQL_DATABASE: ****
MYSQL_USER: ****
MYSQL_PASSWORD: ****
restart: always
ports:
- "3306:3306"
hostname: mysql
phpmyadmin:
depends_on:
- db

ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: ****
restart: always
app:
depends_on:
- db
build: ./unipept-application
command: sleep infinity
ports:
- '5000:5000'
volumes:
- ~/.gitconfig:/root/.gitconfig
- ..:/workspace
user network_mode: "host"in your APP config then you can call the DBfrom your APP using localhost:PORT
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: ****
restart: always
network_mode: "host"
app:
depends_on:

build: ./unipept-application
command: sleep infinity
ports:
- '5000:5000'
network_mode: "host"
volumes:
- ~/.gitconfig:/root/.gitconfig
- ..:/workspace
PS: Published ports are discarded when using host network mode
If you make it an environment variable in your database.yml.erb file, it will be configurable. You even already have an example of this. You can set:
host: <%= ENV.fetch('DB_HOST', 'localhost') %>
In development, just don't set the environment variable, and it will use localhost. In a Docker environment, do set it, and it will use that hostname.
version: '3'
services:
db:
image: mysql
app:
build: .
environment:
DB_HOST: db
ports:
- '5000:5000'
You should also pass things like database credentials the same way.
Could not connect to server at http://localhost:3000. Please check if your server is running.
