I am using windows 7 machine.I installed docker toolbox having version 19.03.5.When I try to fetch docker machine ip am getting error
C:\Windows\system32>docker-machine ip Error getting IP address: Host is not running
So when I check the docker status
docker-machine status default it shows stopped.I tried to start using
docker-machine start default getting error
C:\Windows\system32>docker-machine start default Starting "default"... (default) Check network to re-create if needed... (default) Windows might ask for the permission to configure a dhcp server. Somet imes, such confirmation window is minimized in the taskbar. Error setting up host only network on machine start: C:\Program Files\Oracle\Vir tualBox\VBoxManage.exe modifyvm default --nic2 hostonly --nictype2 82540EM --nic promisc2 deny --hostonlyadapter2 VirtualBox Host-Only Ethernet Adapter #2 --cabl econnected2 on failed: VBoxManage.exe: error: Code E_FAIL (0x80004005) - Unspecified error (extended in fo not available) VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Write)" at lin e 529 of file VBoxManageModifyVM.cpp
I am able to run docker commands.
When I run the command docker-machine ip on docker Quick start terminal it showing ip(192.168.99.100).When I hit the ip getting unreachable.I able am to run the docker image also when I try to access the resources present in that getting unreachable.
It looks like some network issue with Virtual Box for
default VM used by Docker.
Try following steps
It will setup
default VM again in Virtual Box

Note: You will lose all existing Docker Images if any.
As per screenshot attached. Port needs to be exposed in order to make it accessible from Host machine.
docker run -p 9999:8082 nithin4325/demo
You can access it on
8082 is your spring Application port configured and you want to access it to
9999 port on the host.
9999 port is available on the host (no application is running on that port) else might throw Port already in use error
