Docker Cannot Run CURL or WGET Commands To Localhost - docker

I have an issue I discovered while trying to try PHPUnit tests with CURL commands. I always get:
Connecting to `www.example.local` (www.example.local)|127.0.0.1|:80... failed: Connection refused.
I then tried to run wget and curl commands from the container command line, same problem. I have docker working like this.
In my computer’s /etc/hosts
127.0.0.1 www.example.local
127.0.0.1 api.example.local
and so forth and it works when accessing the sites in my browser. In my docker-compse.yml, I have:
version: “3.4”
volumes:
postgres_database :
external: false
mysql_data : {}
schemas:
external: false
services:
php:
build:
context : ./
dockerfile : Dockerfile
network: host
volumes:

- ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
depends_on: [ "postgres"]
ports:

- ./nginx_custom_settings.conf:/etc/nginx/conf.d/nginx_custom_settings.conf
links:

What might I be doing wrong that is preventing me from running curl commands from inside the PHP container?

How to run tests from Docker in PhpStorm?

I configured PhpStorm for running tests from docker container in the IDE by clicking the Run button, but I got the following error when I run them:
Doctrine\DBAL\Exception\ConnectionException : An exception occurred in driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known

But if I go directly to php container it works:
docker exec -it sp_php vendor/bin/phpunit
i setup my ide Docker/PHPUnit config by this guide:
https://www.youtube.com/watch?v=I7aGWO6K3Ho&t=240s
To solve this problem i set this in .env
host: "172.19.0.1" // docker network bridge gateway
port: "3308" // my db port from docker-compose

docker container port map with remote IP (54.xxx.xxx.23) on local development

I'm working as a DevOps for some of the Projects Where I am facing an issue,

Put the public IP where is used local IP its working

Why Dockerfile doesn't run multiple commands

I want use Docker run my project(react+nodejs+mongodb),
Dockerfile:
FROM node:8.9-alpine
ENV NODE_ENV production
WORKDIR /usr/src/app
COPY ["package.json", "package-lock.json*", "npm-shrinkwrap.json*", "./"]
RUN npm install --production --silent && mv node_modules ../
COPY . .
CMD nohup sh -c 'npm start && node ./server/server.js'
docker-compose.yml:
version: '2.1'
services:
chat:
image: chat
container_name: chat
build: .
environment:
NODE_ENV: production
ports:
- "3000:3000"
- "8080:8080"
volumes:
- ./:/usr/src/app
links:
- mongo
mongo:
container_name: mongo
image: mongo
ports:
- "27017:27017"
run docker-compose up --build, the 3000 port is worked, but the 8080 port dies
localhost:3000
localhost:8080
I would suggest create a container for the server and have it seperate from the "chat" container. Its best to have each container do one thing and one thing only (almost like the philosophy behind unix commands)
In any case here is some modifications that I would make to the compose file.
version: '2.1'
services:
chat:
image: chat
container_name: chat
build: .
environment:
NODE_ENV: production
ports:
- "3000:3000"
- "8080:8080"
volumes:
- ./:/usr/src/app
links:
- mongo
mongo:
container_name: mongo
image: mongo
# You don't need to expose this port to the outside world. Because you linked the two containers the chat app
# will be able to connect to mongodb using hostname mongodb inside the container network.
# ports:
# - "27017:27017"
Btw what happens if you run:
$ docker-compose down
and then
$ docker-compose up
$ docker ps
can you see the ports exposed in docker ps output?
your chat service depends on mongo so you also need to have this in your chat
depends_on:
- mongo
This docker-compose file works for me. Note that i am saving the data from the database to a local directory. You should add this directory to gitignore.
version: "3.2"
services:
mongo:
container_name: mongo
image: mongo:latest
environment:
- MONGO_INITDB_ROOT_USERNAME=root
- MONGO_INITDB_ROOT_PASSWORD=password
- NODE_ENV=production
ports:
- "28017:27017"
expose:
- 28017 # you can connect to this mongodb with studio3t
volumes:
- ./mongodb-data:/data/db
restart: always
networks:
- docker-network
express:
container_name: express
environment:
- NODE_ENV=development
restart: always
build:
context: .
args:
buildno: 1
expose:
- 3000
ports:
- "3000:3000"
links:
- mongo # link this service to the database service
depends_on:
- mongo
command: "npm start" # override the default command to use nodemon in dev
networks:
- docker-network
networks:
docker-network:
driver: bridge
You may also find that using node you have to wait for the mongodb container to be ready before you can connect to the database.

connection refused from host to docker container

I'm trying to run a web app within a docker container. This is my docker-compose.yml
version: '2'
services:
web-app:
image: org/webapp
container_name: web-app
ports:
- "8080:8080"
expose:
- "8080"
volumes:
- ./code/source:/source
command: tail -f /dev/null
postgres:
image: postgres:9.5
container_name: local-postgres9.5
volumes_from:
- postgres-data
postgres-data:
image: busybox
container_name: postgres9.5-data
volumes:
- /var/lib/postgresql/data
When I run
docker-compose up -d
I'm able to connect to the web app from within the container with a curl command. When I try to connect from the host, I get a connection refused error
