Using Portainer to Deploy OpenWRT Docker

If you had an already running container that you wanted to change the restart policy for, you could use the docker update command to change that:

docker pull sulinggg/openwrt:latest
docker run --restart always --name openwrt -d --network macnet --privileged sulinggg/openwrt:latest /sbin/init

After deployed the dock, check the ip address allocated from network macnet. You will need to manually set this ip into docker’s /etc/config/network file. 

bash-5.0# cd /etc/config
bash-5.0# nano network 
bash-5.0# cat network

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd7d:334c:6108::/48'

config interface 'lan'
        option type 'bridge'
        option ifname 'eth0'
        option proto 'static'
        option netmask '255.255.255.0'
        option ip6assign '60'
        option ipaddr '192.168.2.96'
        option gateway '192.168.2.1'
        option dns '8.8.8.8'

config interface 'vpn0'
        option ifname 'tun0'
        option proto 'none'

bash-5.0# 

Now you should be able to access your OpenWRT web gui from http://192.168.2.96

Note：

Ubuntu has systemd-resolved listening on port 53 by default. In case you want to run your own DNS server, you can’t because port 53 is already in use, so you’ll get an error similar to this: “listen tcp 0.0.0.0:53: bind: address already in use”.

You have systemd-resolved enabled as the local DNS server. You can disable it by setting DNSStubListener=no in /etc/systemd/resolved.conf and then restart the systemd-resolved service. It will then start without binding to port 53, allowing dnsmasq to bind instead.
