I am running a container in localhost with Python Django (python manage.py runserver 0.0.0.0:80) and I want to access this service in my wifi network...
When I run the server locally (no Docker), it works fine, I can put the IP of my computer in my phone's browser and access the web app.
My PC is not Windows Pro, and I run the Docker Toolbox version which use the VirtualBox to do the Docker stuff. For this reason, the container IP address is 192.168.99.100, and my PC IP is 192.168.0.5
How can I access the docker machine from my phone??
if u have mapped ur conatiner port to some host port, then you should be able to access your app using your the ip of your computer in your wifi network and the mapped port.

There's some virtual machine internal network ip address which is accessible from MAC docker host. This was verified using ping.
However, the same ip address is not accessible from any docker container running on the Docker host.
I tried to run container with --network host, however the ip is still not reachable.
Then, I discovered that none of the VMs reachable from MAC docker host are reachable from any docker container running on it.
How to debug and solve this issue?
External ip addresses (of google.com ) are accessible from the container.
I performed the same test on Linux docker host. The same internal VM ip address was reachable from within the container as well as all other VMs.
It's important to note that MAC docker host is just MAC machine connecting to the network using VPN and thus getting access to internal network VMs.
Linux Docker host is VM itself in the internal network where VMs are located.
I'm using 3.6.0 MAC Docker desktop version and update regularly.
I have a Windows 10 Home machine (local machine) where I have installed Docker Toolbox that runs docker inside a VM. IP (192.168.0.6)
Also, there is another Windows 10 Pro machine (remote machine) that has Docker Desktop installed. IP (192.168.0.13). In the Docker Desktop setting, I have enabled "Expose daemon on tcp://localhost:2375 without TLS". At this point, I do not care about the TLS part since both the machines are on the local network. In the firewall setting, I have accepted inbound connections from port 2375.
Now I would like to run docker-compose from a local machine that connects and runs docker on the remote machine. To test connection, the command used on local machine is
docker -H tcp://192.168.0.13:2375 version
The response is
Cannot connect to the Docker daemon at tcp://192.168.0.13:2375. Is the docker daemon running?
I see that it calls https://192.168.0.13:2375/v1.40/info and not http://192.168.0.13:2375.
And in my remote machine, if I enter http://localhost:2375/v1.40/info I get a response but there is no response when I run by providing IP like http://192.168.0.13:2375/v1.40/info
I assume your docker daemon is only listening on localhost or 127.0.0.1.
You try to connect from another machine which connects to your machine with you internal network ip 192.168.0.13.
This means you need to configure your docker daemon to listen to:
192.168.0.13 = only network internal
tcp://192.168.0.13:2375
0.0.0.0 = all ip addresses
tcp://0.0.0.0:2375
In Windows you need to create a Docker-Daemon config file in:
C:\ProgramData\docker\config\daemon.json
with following content:
{
"hosts": ["tcp://0.0.0.0:2376"] # IP Address for container host
}
You can probably define a Subnet but i am not sure about this.
This is because the VM network interface is only binded to your localhost.
Try forwarding the port. From powershell or command prompt with admin privileges:
netsh interface portproxy add v4tov4 listenport=2375 listenaddress=192.168.0.13 connectaddress=127.0.0.1 connectport=2375
I installed docker on virtual machine and started container there. My container is now running and I want to see the app on my host machine.
docker container ls command returns
PORTS:
0.0.0.0:8080->8080/tcp
but I'm not sure how to work with this, and how to access the app on my host browser.
first you most sure that you could access to vm whit ping or telnet to your VMs IP.
if you don't have access read this link
if you have access your URL will be ---> http://yourVMip:8080
I was doing some devops and writing a script to turn my current host/nginx server/nginx setup into a host/docker/nginx server/docker/nginx set up so I can keep directories and etc the same between them.
The problem is that any ports I expose on a docker container are only accessible on the host and not from any other machines on the host network.
When typing 192.168.0.2 from a machine such as 192.168.0.3 it just says took too long to respond, but typing 192.168.0.2 from 192.168.0.2 will bring up the welcome to nginx page?! The interesting part is I did a wireshark analysis on en0 on port 80 and there are actually some packets coming through
See pastebins of packet inspections:
LAN to docker: https://pastebin.com/4qR2d1GV
Host to docker: https://pastebin.com/Wbng9nDB
I've tried using docker run -p 80:80 nginx/nginx and docker run -p 192.168.0.2:80:80 nginx/nginx and docker run -p 127.0.0.1:80:80 nginx/nginx but this doesn't seem to fix anything.
Should see welcome to nginx when connecting from 192.168.0.3 to 192.168.0.2.
this is in my dev environment which is an osx 10.13.5 system.
when I push this to my ubuntu 16.04 server it works just fine with the containerized nginx accessible from the www and when I run ngnix on my host without docker I can connect from external machines on the network too
Your description is a bit confusing the 127.0.0.1 within the port line will bind it to localhost only - you won't be able to access the docker from another machine. Remove the IP address and you should be able to access the docker from outside localhost.
I have an Ubuntu host with a web app running inside a docker container.
The web app is accessible from Ubuntu PC via 172.19.0.XXX:8080.
Now I want to test how web app looks like in IE. For that I started VirtualBox with Win7.
How could I call web app from VM?
Already tried different VM network variants, such as default NAT with port forwarding; and bridge - without any luck
Thanks in advance!
You can map the ports between the docker container and the Ubuntu host when starting the container by using -p 8080:8080, then you should be able to connect from Ubuntu using localhost:8080
Once you do that, find the IP address of the Ubuntu host by running ifconfig and use that IP to connect from the Windows VM via http://<Ubuntu-ip>:8080
