Problems accessing the application from the browser

I want to be able to access/view my applications through the browser using Docker. I installed Docker for Windows, did not make any additional configuration, and created the files below, along with the following tests.

I got into the container, > php artisan serve, resulting in:

Laravel Development server Started: http://127.0.0.1:8000

With the application running, I opened another terminal and ran the code curl http://127.0.0.1:8000, he returned me the initial page of the project without problems.

I tried to access via Google Chrome, localhost:8000, got error This page isn’t working localhost didn’t send any data. ERR_EMPTY_RESPONSE

With the container running, I ran the command docker ps to see the doors, result: 0.0.0.0:8000->8000/tcp, 0.0.0.0:8888->80/tcp, 0.0.0.0:80->8000/tcp, 0.0.0.0:8080->8000/tcp php-api-container

I tried to see the IP of the Docker-machine, but there is no.

I tried using the Internet Virtual Switch IP, the error continues.

I tried to access by all ips, which were shown on my machine ipconfig.

Root of the Project

  • /grimorie-api (Basic Laravel Installation)
  • Docker-Compose.yml
  • php. Dockerfile

laravel docker docker-windows

  • Kaue, did you ever run this in linux? It seems to me to be an Issue of Docker for windows itself, something like this https://github.com/docker/for-win/issues/197

  • Another thing, instead of entering the container, specify this in your Dockerfile, with CMD or ENTRYPOINT...

  • When you say Docker for windows, it’s the Desktop or Toolbox?

  • Docker Desktop for Windows Link: https://www.docker.com/products/docker-desktop

  • @Tuxpilgrim not tested on linux yet, I have to run Docker in a windows environment unfortunately.

  • I know what Kaue looks like (:p), have you seen this Volume I sent? You can run the test directly on dockerfile’s ENTRYPOINT, and see if something changes.

Testing here the problem seems to me to be like the php artisan serve. It failed to properly expose the network to windows properly.

To correct that, I passed the argument --host 0.0.0.0 for the command and worked with localhost:

Navegador com localhost

saida do php artisan serve

I changed the Docker-Compose.yml a little bit to the following:

version: "3.7"

services:
  php-api:
    image: php:zts-alpine3.9 
    ports:
      - "8000:8000"
    working_dir: "/var/www/html"
    command: "php artisan serve --host 0.0.0.0"
    volumes:
     - ".:/var/www/html"

As there is no customization on Dockerfile I was able to do everything in there. Notice the instruction command, with it when rotating docker-compose up he will execute php artisan serve --host 0.0.0.0 automatically for me.

There’s not much point in using localhost, the network of a "container" I believe is the part, so the way is to actually get the container IP, this reply on Soen suggests executing docker inspect in this way:

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <nome do container ou id>

If it is windows:

docker inspect -f "{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}" <nome do container ou id>

I don’t know if the syntax is correct for new versions of Docker, because the answer is old.

Now if it doesn’t work inside Docker you can run commands, then try simply running ifconfig, will display "all" interfaces and their Ips, gateways, etc, you will probably be able to access (if you don’t have any blockage by Laravel, I don’t know if "this exists"), by your command docker ps looks like the outer door is 8000 even.

  • These 2 commands returned me the ips of the containers, but none of the 2 made me get to see the Laravel by the broser unfortunately.

  • @Kauealves the commands are not to see, but to pick up the IP of Docker, did you get the IP? Tried to run a ping in it?

  • @Guilhermenascimento with Docker for Desktop integrates the Docker NAT network with localhost. If you are using this version it is possible to use localhost without problems.

  • @gmsantos understand, but as it is not apache and nor Nginx, but only "php built in server" I imagine that the situation is not configuration or failure of the internal part "http", what it seems to me was some adjustment or customization (or lack of adjustment) at the bridge, but I understand very little of this to say anything. I really fear that the problem is in INFRA (in equipment) which would make the question more OFF-TOPIC yet.

  • but it could be something else too\(ツ)/¯

  • @gmsantos but it is just what I am saying, below can be anything, which probably leads to off-topic :/ , the config of ap port also did not seem right, I noticed your answer and probably is the case (may be more of a problem).
