Setting up docker on the mac: Cannot connect via localhost
I’m just setting up docker on my Mac. The installation worked and I got some containers running (following the getting-stared guide), but now I want to connect with my browser to localhost, to show a web app.
For that I’m following this guide: https://docs.docker.com/engine/userguide/containers/usingdocker/
In the last section it is said, that you simple go with your browser to: localhost:XXXXX wheras XXXXX is the port, that you found out using the command
docker ps -l
First problem: here nothing happends. The browser is showing an empty page (ERR_CONNECTION_REFUSED)
Further more in the guide it is explained, that for Mac you can check your ip address via the command:
docker-machine ip your_vm_name
Here appears the second problem: This command results in an error-message:
Host does not exist: "your_vm_name"
So my questions are:
How to set up the virtual machine (or “your_vm_name” respectively)?
Does it have to do anything with the vhosts file on my Mac OS?
Is there mybe a conflict with MAMP (which I’m also using sometimes)?
Thanks in advance!

Hello the process to start to use docker on mac with docker-machine is like:
Create a new docker machine on virtualbox, you can use a name like “your_vm_name” or just “default” in this way you can not use the name because “default” is a keyword that docker-machine try to use when you don’t specify nothing.
The problem here is, why docker-machine ip your_vm_name doesn’t provide the good ip? Can you copy the result of your command
Usually it’s 192.168.99.100
thanks a lot
And thanks to GianArb for the very fast answer! That solution works as well.
Just to contribute to the community, I just found out by myself, that the solution was too simple to be true.
Instead of your-vm-name use default (obviously the default-host that is set up by docker), so I just used:
docker-machine ip default
and then I got the right IP.
