I suggest using Octane, because default Kubernetes Dashboard is a bit hard to configure correctly
user@master:~$ wget https://github.com/vmware-tanzu/octant/releases/download/v0.12.1/octant_0.12.1_Linux-64bit.deb
user@master:~$ dpkg -i octant_0.12.1_Linux-64bit.debUse OCTANT_LISTENER_ADDR=0.0.0.0:7777 to allow connections from any host
OCTANT_LISTENER_ADDR=0.0.0.0:7777 octantIf you are in production, set OCTANT_ACCEPTED_HOSTS to the value of the host you are trying to connect to Octant from, and OCTANT_LISTENER_ADDR to host IP
OCTANT_ACCEPTED_HOSTS={EXTERNAL_IP} OCTANT_LISTENER_ADDR={SERVER_IP}:80 octantuser@master:~$ cd /tmp
