Step 4 - Working with Docker ImagesДocker containers are built from Docker images. To view system-wide information about Docker, use: To view the options available to a specific command, type: Wait Block until one or more containers stop, then print their exit codes Version Show the Docker version information

DOCKSTATION UBUNTU UPDATE

Update Update configuration of one or more containers Unpause Unpause all processes within one or more containers Top Display the running processes of a container Tag Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE Stats Display a live stream of container(s) resource usage statistics Start Start one or more stopped containers

DOCKSTATION UBUNTU ARCHIVE

Save Save one or more images to a tar archive (streamed to STDOUT by default) Push Push an image or a repository to a registry Pull Pull an image or a repository from a registry Port List port mappings or a specific mapping for the container Pause Pause all processes within one or more containers Load Load an image from a tar archive or STDIN Inspect Return low-level information on Docker objects Import Import the contents from a tarball to create a filesystem image Output attach Attach local standard input, output, and error streams to a running containerД¬ommit Create a new image from a container's changesД¬p Copy files/folders between a container and the local filesystemДiff Inspect changes to files or directories on a container's filesystemД®vents Get real time events from the serverД®xec Run a command in a running containerД®xport Export a container's filesystem as a tar archive If you attempt to run the docker command without prefixing it with sudo or without being in the docker group, youвЂ™ll get an output like this: Step 2 - Executing the Docker Command Without Sudo (Optional)Д«y default, the docker command can only be run the root user or by a user in the docker group, which is automatically created during DockerвЂ™s installation process.

WeвЂ™ll explore how to use the docker command later in this tutorial. Installing Docker now gives you not just the Docker service (daemon) but also the docker command line utility, or the Docker client. в””в”Ђ7854 /usr/bin/dockerd -H fd:// -containerd=/run/containerd/containerd.sock Loaded: loaded (/lib/systemd/system/rvice enabled vendor preset: enabled)ДЄctive: active (running) since Fri 21:30:25 UTC 22s ago

rvice - Docker Application Container Engine.YouвЂ™ll see output like this, although the version number for Docker may be different:

DOCKSTATION UBUNTU INSTALL

Make sure you are about to install from the Docker repo instead of the default Ubuntu repo:

Update your existing list of packages again for the addition to be recognized:

echo 'deb $(lsb_release -cs ) stable' | sudo tee /etc/apt//docker.list > /dev/null.

curl -fsSL | sudo gpg -dearmor -o /usr/share/keyrings/docker-archive-keyring.gpgДЄdd the Docker repository to APT sources:.

Then add the GPG key for the official Docker repository to your system:

sudo apt install apt-transport-https ca-certificates curl software-properties-common.

Next, install a few prerequisite packages which let apt use packages over HTTPS: To do that, weвЂ™ll add a new package source, add the GPG key from Docker to ensure the downloads are valid, and then install the package.ДЇirst, update your existing list of packages: To ensure we get the latest version, weвЂ™ll install Docker from the official Docker repository. The Docker installation package available in the official Ubuntu repository may not be the latest version.

An account on Docker Hub if you wish to create your own images and push them to Docker Hub, as shown in Steps 7 and 8.

One Ubuntu 22.04 server set up by following the Ubuntu 22.04 initial server setup guide, including a sudo non- root user and a firewall.To follow this tutorial, you will need the following: YouвЂ™ll install Docker itself, work with containers and images, and push an image to a Docker Repository. In this tutorial, youвЂ™ll install and use Docker Community Edition (CE) on Ubuntu 22.04. TheyвЂ™re similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.ДЇor a detailed introduction to the different components of a Docker container, check out The Docker Ecosystem: An Introduction to Common Components. Containers let you run your applications in resource-isolated processes. Docker is an application that simplifies the process of managing application processes in containers.
