3

I am having an issue with my dockerized webapp. Essentially I have a docker-compose yaml file and when the file is ran, everything seems to boot up smoothly. I can see that the container is running using docker ps. I can see that it is listening to the correct ports, however when I try to connect via my browser, it refuses to connect.

My yaml file

version: '3'
services:
  product-search-service:
    build: ./product-search-app
    ports:
      - 8000:5000
  product-shipping-service:
    build: ./product-shipping-app
    ports:
      - 9000:5000
  website-app:
    build: ./web-app
    ports:
      - 127.0.0.1:8080:80
    volumes:
      - ./web-app/public-html:/usr/local/apache2/htdocs/

I am connecting via the web browser to 127.0.0.1:8080

The console logs

Starting webstore-services_product-shipping-service_1 ... done                                                                                               Recreating webstore-services_website-app_1            ... done                                                                                               Starting webstore-services_product-search-service_1   ... done                                                                                               Attaching to webstore-services_product-shipping-service_1, webstore-services_product-search-service_1, webstore-services_website-app_1

I would also like to note that I have been following this tutorial and I can confirm that all prior steps were completed correctly as I have done this multiple times now

https://cpit490.gitlab.io/labs/lab-8/

Are there any logging features I can enable to get a better look at whats happening when I try to connect to 127.0.0.1 ?

EDIT

Attaching screenshot of the error

enter image description here

EDIT 2

Dockerfile for the web-app

FROM httpd:2-alpine
EXPOSE 80
EXPOSE 443

Edit 3

I am using docker toolbox in case this makes any difference. I don't have win10 pro or enterprise so I had to use toolbox

  • Please include the output of `docker run --rm --net container:${cid} nicolaka/netshoot ss -lnt` where `${cid}` is the container id for the website-app container. – BMitch Mar 13 '20 at 12:30
  • Hi @BMitch I am not sure if I have ran this correctly, but here is the command ran and the output I received $ docker run --rm --net container:b605c0901b9f nicolaka/netshoot ss -lnt Unable to find image 'nicolaka/netshoot:latest' locally C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on 10.0.2.3:53: read udp 10.0.2.15:34228->10.0.2.3:53: i/o timeout. See 'C:\Program Files\Docker Toolbox\docker.exe run --help – LukeR97 Mar 13 '20 at 12:43
  • Do you have internet connectivity? Indicates that your DNS server could not find docker hub. If you're in a disconnected environment, you'll need to pull that image through other means first. – BMitch Mar 13 '20 at 12:49
  • The screenshot shows an attempt to connect to port 8081, not 8080 though... – Gimby Mar 13 '20 at 12:51
  • Yep have internet connectivity. I have some other docker projects which I've ran and they connect just fine. In regards to the port. I have tried 8080, 8081, 443, 80, etc. – LukeR97 Mar 13 '20 at 12:59
  • Try to pull the image, or run other commands that would cause the docker engine to use DNS. E.g. since you're on docker machine, the engine is in a VM, so `--net host` is the VM: `docker run --net host busybox ping google.com` – BMitch Mar 13 '20 at 13:34
  • My problem was that after I edited the `docker-compose.yml` (added port mapping) i only called `docker-compose restart` that did not recreate containers with ports mapped. – Najiva Sep 14 '22 at 10:48

So I have figured out the issue.

Because I am running Docker Toolbox on Win10 home, my docker is running from VirtualBox which has its own IP address. To connect to my webapp, I need to use VB's IP instead of my local host. Win10 home doesn't have a hypervisor so localhost is essentially locked out from me :(

Credit goes to Docker Toolbox - Localhost not working

It seems that you didn't map correctly container's ports with localhost. Update your yaml file like below:

version: '3'  
services:      
product-search-service:

          build: ./product-search-app
          ports:
            - 8000:80
            - 8001:443      
product-shipping-service:

          build: ./product-shipping-app
          ports:
            - 9000:80
            - 9001:443      
website-app:

          build: ./web-app
          ports:
            - 8080:80
            - 8081:443
          volumes:
            - ./web-app/public-html:/usr/local/apache2/htdocs/

Now you can browse to localhost:8080 or localhost:8081

  • Hey thank you for the answer. Unfortunately it didn't seem to work. I tried sending a curl request from command prompt, but even that refuses to connect. – LukeR97 Mar 13 '20 at 12:15
  • attached now. Network tab doesn't show any info just the document request – LukeR97 Mar 13 '20 at 12:23
  • now also EXPOSE ports of website-app (in dockerfile) like EXPOSE 80 EXPOSE 443 – Muneer Nasir Mar 13 '20 at 12:30
  • Tried this just now. Same result. I have included the full dockerfile for the web-app in the new edit. The dockerfile was provided by the tutorial I linked in my post, so I have just added the Exposes like you have asked – LukeR97 Mar 13 '20 at 12:46
