Create a Docker Container in the Host network

 

#Start a new container - which has the same ip as Host Container
docker run -it --network host kalilinux/kali-rolling

#Start a container 
docker start Container_ID

#Attach a container 
docker attach Container_ID
ctrl+p & ctrl+q to detach from a container without killing it 

#Start a container in Detached mode
docker run -d --network host kalilinux/kali-rolling

#Start a container in bridge network 
#Default is bridge network
docker run -dit --name test kalilinux/kali-rolling /bin/bash

Bridge network = new Docker network - separate network
Host = Docker Host network 

#Create a bridge network
docker network create --driver=bridge my_bridge_network --subnet=10.10.10.0/24 --gateway=10.10.10.1

#Run the container in Bridge network 
docker run -it --name my_container --network my_bridge_network --ip 10.10.10.2 ubuntu:latest

Moving Docker Container to a Different Host 

#list the containers and copy the id
docker container ls 

#stop the container
docker stop <Container_ID_or_name>

#Create a new image 
docker commit <container_ID> <new_name:tag>

#save the image to a tar file to export
docker save -o <container_backup.tar> <Image_name>

#Push the container to a new Host
scp <container_backup.tar> root@10.10.10.10:/home/backup/

#Login to the new host and load the container, might take some time based on the container size
docker load -i <container_backup.tar>

#List the images, confirm your new docker container here 
docker images

#Create/run the container 
docker create --name kali container_backup
docker container container_id start
or
#create and start the container 
docker run -it --name kali --hostname kali <Image_id> 

#Setup auto restart
docker update --restart unless-stopped kali

#Verify restart status
docker inspect -f '{{.HostConfig.RestartPolicy.Name}}' kali

#make sure docker starts on boot
sudo systemctl enable docker

Basic Docker Commands

#list containers
sudo docker ps 

#Get a shell 
docker exec -it <container_name_or_id> /bin/bash
