Docker basic command

docker.md

tipe: we can have a lot of containers base on an image

run a docker image. it download image if not present in local

sudo docker run hello-world 

list all docker images

sudo docker images

show all previously run container

sudo docker ps -a

download a docker image from hub.docker.com

sudo docker pull hello-world

run a docker image and then run the echo command from the created container

sudo docker run busybox echo "Hello from busybox"

Send stop signal to busybox container and wait for 30 seconds then if it still running kill the process

docker stop --time=30 busybox

remove previously created container by it is number (648795252)

sudo docker rm 648795252

remove docker image by it is name

sudo docker rmi hello-world

remove all previously created docker containers

sudo docker container prune

run docker image and after it finished remove the container

sudo docker run --rm hello-world

Run docker image and give me the interactive shell inside the container

sudo docker run -it hello-world

Give me the interactive shell inside the container with bash

docker exec -it hello-world bash

Execute a command in a running container

sudo docker exec 648795252 touch "/hi"

Run the Redis image and map port 6379 on the container to 100 in the host OS

sudo docker run -p100:6379 redis

create a name for container to access it without it's number

sudo docker run --name hello hello-world

run image in background (daemon)

sudo docker run -d hello-world

Map /data in container to /tmp/data in host os, this way we can create persistent storage for redis

sudo docker run redis -v /tmp/data/redis:/data

Create an image from a docker file in current directory

sudo docker build .

Build image and add tag, version to it

sudo docker build -t myapp:v1 .

Show already created docker network

sudo docker network ls

create a network with mynet name

sudo docker network create mynetwork

run a docker image and use mynet network this way running docker container can access other containers with thir name

docker run redis --network mynet
