Adding my two cents.

• Ports
  All examples so far are getting ports from 0.0.0.0, but (for those that don't know), we can listen to a port in a specific IP, not just 0.0.0.0 (or *).
  This way we can have different services in the same port, but with different IPs (to access both you will probably need a reverse proxy or edit /etc/hosts or your DNS, but it is out of scope here).

docker run -d ...  -p 192.168.32.12:53:53 ...
docker run -d ...  -p 192.168.44.5:53:53 ...

I use it in my PiHole, and virt-manager. PiHole listens my LAN IP, virt-manager listens its own subnet...

I am using this to extract the ports from all IPs. To get IPv6, I am using a different expression.

container_ports=( $(docker port "$container_id" | grep -o -e ":[0-9]\+*" | cut -f2 -d:) )

• IPAddress and Gateway
  The same container can be added to different Networks, and on each one it will get its own IP and Gateway. The commands are correct, but it is better to add a space just to visually represent better.

container_ip="$(docker inspect --format "{{range .NetworkSettings.Networks}}{{.IPAddress}} {{end}}" "$container_id")"
container_gateway="$(docker inspect --format "{{range .NetworkSettings.Networks}}{{.Gateway}} {{end}}" "$container_id")"

• Networks
  Still in the case of a container in multiple networks, just .HostConfig.NetworkMode won't give you all of them.
  Loop .NetworkSettings.Networks to get key and value and print just the key.

container_network=( $(docker inspect --format "{{range \$k, \$v := .NetworkSettings.Networks}}{{printf \"%s\n\" \$k}}{{end}}" "$container_id") )

For now, I am happy with this.
Other changes:

• search for ID or Name
• only calls inner function if ID/Name found
• show only ID's first 6 chars
• inspect only network or only container

Anyone wanna add these changes to the repo version? https://github.com/GammaGames/dz
It’s also got a command to sh into containers.

showing local ports might be useful too, sometimes I bind stuff to 127.0.0.1 and they don’t show up

Edit: brccabral, thanks for the pr! I've also updated the ip function to show host ip when the container isn't listening on 0.0.0.0 since your changes made that way easier to implement, here's what that looks like with a bunch of different configs:

Container Ports
5432:5432/tcp
127.0.0.1:9090:80/tcp
127.0.0.1:8082:80/tcp
127.0.0.1:8084:80/tcp
127.0.0.1:9093:80/tcp
127.0.0.1:8083:80/tcp
host                           
127.0.0.1:9092:80/tcp
9200:9200/tcp 9300:9300/tcp

If anyone interested, GammaGames repo has many updates now, https://github.com/GammaGames/dz . Specially for speed, running the inspect in a single command returns data much faster
