On a Single Machine

build images from configuration file

docker build -t <tag> -f <path/to/Dockerfile> .

files copying between host and containers

docker cp host_source_path container:destination_path

docker cp container:source_path host_destination_path

interactive with exisiting container
```
docker exec -it <container> bash
```
run images interactively
```
docker run -it <image>
```
remove container automatically when it exit
```
# using --rm 
docker run --rm <image>
```

clear exited containers

docker rm $(docker ps -a -q -f status=exited)

# in higher version
docker container prune

give an port automatically to container
```
docker run -d -P --name <GIVEN CONTAINER NAME> <image>
```
In the above command, -d will detach our terminal, -P will publish all exposed ports to random ports and finally --name corresponds to a name we want to give. Now we can see the ports by running the docker port [CONTAINER] command.

specify a port to a container

docker run -p <host port>:<container port> <webapp image>

launch a composed application:
```
docker-compose up -v -d
```
-v means verbose, -d means detaching from terminal.
check the network running
```
docker-compose ps
```
stop a composed application
```
docker-compose down -v 
```
This would kill all the containers and remove all data volumes if there any. Then we need to remove the network
```
docker network rm <network-name>
```
To list all the network we have now, use docker network ls.
inspect a network
```
docker network inspect <network-name>
```
This would print out the infomation in JSON format.
