Use tap interface to connect to app

Create interfaces

sudo tunctl -t tap0 -u `whoami`
sudo brctl addbr br0
sudo brctl addif br0 tap0
sudo ip link set up dev br0
sudo ip link set up dev tap0
sudo ip a add 11.11.11.1/24 dev br0

We define IP to access from the host to app inside EVE

Create dnsmasq config (sample below)

log-queries
log-dhcp
bind-interfaces
except-interface=lo
dhcp-leasefile=/run/dnsmasq.leases
interface=br0
dhcp-range=11.11.11.3,11.11.11.114,60m
dhcp-option=option:router,11.11.11.1
dhcp-host=d0:50:99:82:e7:2b,11.11.11.21

In the sample we define static host with MAC d0:50:99:82:e7:2b and IP 11.11.11.21.

Run dnsmasq

sudo dnsmasq --no-daemon --log-queries --conf-file=/conf/dhcp.conf, where /conf/dhcp.conf - is path to configuration file. You can use your favourite DHCP server here.

Prepare and run EVE

make build
./eden config add default
./eden setup
./eden start --with-tap=tap0
./eden eve onboard

Create network and application

./eden network create --type=switch --name=tap-net --uplink=eth2
./eden pod deploy docker://lfedge/eden-eclient:83cfe07 --networks=tap-net:d0:50:99:82:e7:2b

We use eth2 here, because of tap interface is connected as the third one (eth0 and eth1 used with qemu`s user networks). We define the same MAC for the app as we described in dnsmasq config above.

Try to connect to app

ssh -i tests/eclient/image/cert/id_rsa [email protected]
