IPvlan

ip addr

docker network create -d ipvlan \
    --subnet=192.168.50.0/24 \
    --gateway=192.168.50.1 \
    -o ipvlan_mode=l2 \

Overlay

(host 1) ip addr
(host 1) sudo ethtool -K ens33 tx-checksum-ip-generic off

(host 2) ip addr
(host 2) sudo ethtool -K ens33 tx-checksum-ip-generic off

(host 1) docker swarm init
(host 2) docker swarm join ...
(host 1) docker network create -d overlay --attachable my-overlay-net
(host 1) docker network ls

(host 1) docker run -d --name myapp --network my-overlay-net aputra/myapp-188:v3
(host 2) docker network ls
(host 2) docker run -dit --name myapp-v2 --network my-overlay-net aputra/myapp-188:v3
