Installing Docker

Add Docker’s GPG key

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

Setup the Docker Repo

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Install the Docker Engine

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Pull an Image from DockerHub

sudo docker pull debian

Create a Docker Image from a Running Container

docker commit [container ID] [new image name]

E.g.

docker commit busy_wiles nadimdg/xmrig:auto4

List All Running Containers

docker ps

List All Containers

docker ps -a

Delete a Container

docker rm <container-name>

List all Docker Images

docker images

Delete a Docker Image

docker rmi <image-name>

docker exec -it xmrig-dev /bin/sh

Run a Container

This starts the container and detaches the process from it.

docker run -di --name flast101 alpine:latest

Where:

-d: detach
-i: interactive

Stop a Container

docker stop <image-name>

Create a Container from a Dockerfile

Create a Dockerfile

First create a docker file. An example is shown below, let’s call it p2pooldev.Dockerfile.

FROM p2pool:built
WORKDIR /opt/p2pool
CMD ["/opt/p2pool/p2pool"]

The FROM keyword indicates which docker image the container is built from.
The WORKDIR keyword sets the current working directory for the CMD.
The CMD keyword holds the command to be executed.

Note that if the CMD requires arguments, then in the Dockerfile you must split the command and it’s arguements as shown below:

CMD ["/bin/ls", "-l", "-t", "-r"]

Create a Docker Image from a Dockerfile

docker build -f p2pooldev.Dockerfile -t sallykolodny/db4e:p2pooldev .
