When i try to access my lambda endpoint from outside i receive this error:
curl -XPOST 127.0.0.1:3000/create-loan
Recv failure: Connection reset by peer
But inside docker the endpoint work, the port 3000 does not working from outside.
Any help?

By the compose file you've exposed the port 3001
ports:
- "3001:3000"
But connecting to 3000

I was trying to connect mariadb with wordpress (mariadb-client), and got an error :
Can't connect to MySQL server on 'mariadb'
So I tested ports are good. But while other ports like nginx:80 or wordpress:9000 can be accessed by the other containers, ports of mariadb refuses connections.
I couldn't figure out what is difference between mariadb container and the others. What's the problem?
The ENTRYPOINT of your MariaDB Dockerfile is
ENTRYPOINT ["tail", "-f"]
so it doesn't actually run MariaDB.
You probably need to comment that out and comment back in
ENTRYPOINT ["/docker-entrypoint.sh"]
I was confused about ports. I thought that each containers could communicate by just opening ports, but there was no LISTENing ports. Docker-compose ports: just binds ports and has nothing to do with LISTEN.

when i hit docker-compose up, the courseshine_api service is not stand and throw Could not find rake-13.0.3 in any of the sources (Bundler::GemNotFound). Why this problem occur and how to fix this ..
I am trying to containerise my application which is developed using technologise like DRF, Celery and Redis (as a broker).
I want to prepare docker-compose which will start all the three services (DRF, Celery and Redis (as a broker).
I also want to prepare the Dockerfile.prod for deloyment.
Here is what I have done so far -
version: "3"
services:
redis:
container_name: Redis-Container

expose:

The problem with the existing docker-compose is it returns the error as stated below -
celery-container | [2020-10-08 16:59:25,843: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**#127.0.0.1:5672//: [Errno 111] Connection refused.
celery-container | Trying again in 32.00 seconds... (16/100)
In Setting.py I have defined this for radis connection
REDIS_HOST = 'localhost'
REDIS_PORT = '6379'
BROKER_URL = 'redis://' + REDIS_HOST + ':' + REDIS_PORT + '/0'
BROKER_TRANSPORT_OPTIONS = {'visibility_timeout': 3600}
CELERY_RESULT_BACKEND = 'redis://' + REDIS_HOST + ':' + REDIS_PORT + '/0'
I don't know how should I extend my Dockerfile which is current used for the development, to form a Dockerfile.prod which could be deployable.
All of my three containers are working -
You need to change your REDIS_HOST in your Setting.py to be “redis” instead of “localhost”.
I used docker-compose to create docker containers in my React, Node.js, and Postgres structured project.
After I created Dockerfile and docker-compose.yml, I did docker up 'docker-compose up --build.'
Then, I wasn't be able to create containers, and get an errors.
I get Error says:
Error 1
Error 2
Error 3
How can I fix it and successfully build containers?

I am following this tutorial from docker Docker Rails and I have created a folder and added this code below in my docker file.
FROM ruby:2.5
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
RUN mkdir /myapp
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
COPY . /myapp
And my docker compose file code is:
version: '3'
services:
db:
image: postgres
volumes:
- .data:/var/lib/postgresql/data
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
volumes:
- .:/myapp
ports:
- "3000:3000"
depends_on:
- db
I am following tutorial when I am running docker compose up I can just see this error:
Could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
What is wrong here I don't know how to inspect and detect error how to fix this.
You need environment variables within your web container so that it knows how to connect to the db container.
version: '3'
services:
db:
image: postgres
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=
volumes:
- ./data:/var/lib/postgresql/data
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
environment:
- PGHOST=db
- PGUSER=postgres
volumes:
- .:/myapp
ports:
- "3000:3000"
depends_on:
- db
Please go to your database.yml and add host set to db , then username and password and run the command again.
