    Customizing of Kernel tunables below is solving issue "no route to host" between docker containers:

    sysctl net.bridge.bridge-nf-call-iptables=0
    sysctl net.bridge.bridge-nf-call-arptables=0
    sysctl net.bridge.bridge-nf-call-ip6tables=0
    

    These control whether or not packets traversing the bridge are sent to iptables for processing.

    Note if you'll add it to sysctl.conf it may not automatically apply during reboot as known bug depending on your linux distribution.
