In this repository you can find a demo to create a docker image based on ubuntu with python3.7, postgreSQL and nginx installed

Open a terminal and run this command to pull the image

docker pull davidezanin/demodocker:x.x.x

To create the docker image, docker file should be in this folder, use release version instead of x.x.x (e.g. RELEASE=7.1.5):

docker build --build-arg RELEASE=x.x.x -t davidezanin/demodocker:x.x.x .

To create and start the container:

sudo docker run -d --name demodockerContainer -p 80:80 davidezanin/demodocker:x.x.x

To create and start the container using the console (example to try flat project):

sudo docker run -it --name demodockerContainer -p 80:80 davidezanin/demodocker:x.x.x /bin/sh

To start after the first run:

docker start demodockerContainer

To stop:

docker stop demodockerContainer

To inspect:

docker inspect demodockerContainer

To open bash (or running command) on running container in detached mode

docker exec -i -t demodockerContainer bash

List running containers:

docker ps

List all containers:

docker ps -a

List all images:

docker images

Delete containers:

docker rmi <ContainerID1> <ContainerID2> ...

Delete images:

docker rmi <ImageID1> <ImageID2> ...

Delete all images:

docker rmi $(docker images -q)

Delete all containers:

docker rm $(docker ps -a -q)

Delete dangling images:

docker rmi -f $(docker images -f "dangling=true" -q)

Delete - all stopped containers, - all networks not used by at least one container, - all volumes not used by at least one container, - all dangling images, - all dangling build cache , - and with the option --volumes also unused volumes,

docker system prune --volumes

##Push on dockerhub

Push images on dockerhub (tagged during build):

docker login docker push davidezanin/demodocker
