Install Docker On Arch

MicroK8s is the simplest production-grade upstream K8s. Lightweight and focused. Single command install on Linux, Windows and macOS. Made for devops, great for edge, appliances and IoT. Full high availability Kubernetes with autonomous clusters. Elementary OS 0.4.1. Elementary OS 5.1.3. Install docker on your Linux distribution. Choose your Linux distribution to get detailed installation. Free downloads for building and running.NET apps on Linux, macOS, and Windows. Runtimes, SDKs, and developer packs for.NET Framework,.NET Core, and ASP.NET. Finally, install Docker: sudo apt install docker-ce Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it's running: sudo systemctl status docker The output should be similar to the following, showing that the service is active and running. Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository. Raspbian users cannot use this method! For Raspbian, installing using the repository is not yet supported. You must instead use the convenience script.

1. Install MicroK8s on Linux

   sudo snap install microk8s --classic

   Don't have the snap command? Get set up for snaps

2. Check the status while Kubernetes starts

3. Turn on the services you want

   microk8s enable dashboard dns registry istio

   Try microk8s enable --help for a list of available services and optional features. microk8s disable turns off a service.

4. Start using Kubernetes

   microk8s kubectl get all --all-namespaces

   If you mainly use MicroK8s you can make our kubectl the default one on your command-line with alias mkctl='microk8s kubectl'. Since it is a standard upstream kubectl, you can also drive other Kubernetes clusters with it by pointing to the respective kubeconfig file via the --kubeconfig argument.

5. Access the Kubernetes dashboard

6. Start and stop Kubernetes to save battery

   Kubernetes is a collection of system services that talk to each other all the time. If you don't need them running in the background then you will save battery by stopping them. microk8s start and microk8s stop will do the work for you.

Self-healing high availability clusters

Automatic data store, API services and leader election

MicroK8s automatically chooses the best nodes for the Kubernetes datastore. When you lose a cluster database node, another node is promoted. No admin needed for your bulletproof edge.

Lightweight upstream Kubernetes

No APIs added or removed

MicroK8s is small, with sensible defaults that ‘just work'. A quick install, easy upgrades and great security make it perfect for micro clouds and edge computing.

Best of breed

Enterprise

• Clustering
• Auto-updating
• Confinement
• Storage

Networking

• CoreDNS
• Ingress
• Istio
• Linkerd

Built-in

• Registry
• Knative
• Kubeflow
• GPU support

Full enterprise support available,
with no subscription needed

Optional 24/7 support with 10 year security maintenance

As the publishers of MicroK8s, we deliver the world's most efficient multi-cloud, multi-arch Kubernetes.

Embedded Kubernetes – try a Raspberry Pi cluster

ARM or Intel. Standalone or cluster. Minimal space, maximum edge.

Under the cell tower. On the racecar. On satellites or everyday appliances, MicroK8s delivers the full Kubernetes experience on IoT and micro clouds.

Fully containerized deployment with compressed over-the-air updates for ultra-reliable operations.

Zero-ops infrastructure

Set it up and let it run

Our goal is to eliminate everyday administration from Kubernetes clusters.

Install, cluster, and then just watch it fly. You can configure MicroK8s if you want. Most people don't bother.

MicroK8s will apply security updates automatically by default, defer them if you want. Upgrade to a newer version of Kubernetes with a single command. It's really that easy.

Fully containerised Kubernetes

MicroK8s runs in an immutable container

People love Docker images because they have no moving parts, for better security and simpler ops.

MicroK8s also runs in an immutable container, so your Kubernetes itself is fully containerised. It sounds like an infinite loop, but it works quite nicely.

Sensible defaults

Kubernetes has a million options. We select the most popular and reliable.

MicroK8s defaults to the most widely used Kubernetes options, so it ‘just works' with no config necessary. Networking, storage and standard services are all provided out of the box with best of breed defaults.

GPU acceleration

Nvidia auto-detection with CUDA at the ready

Pass GPUs to docker apps for deep learning. Define AI pipelines with Kubeflow on your workstation.

We work with Amazon, Azure, Google, Oracle and IBM to simplify multi-cloud GPU enablement. Build and test locally on MicroK8s, then deploy to EKS, AKS or GKE with confidence.

Batteries included

Tracing. Metrics. Service Mesh. Registry.

Prometheus is popular for metrics, so we bundled it. Just like Jaeger, Istio, LinkerD and KNative.

Turn them on or off with one command.

Automatic security updates

Let it roll, or take control

Choose stable security releases only, or try release candidates, betas and daily builds. MicroK8s can update automatically, with rollback on failure.

Stick with a major version, or follow the latest upstream work. Go with the flow, or take control in the enterprise to specify versions with perfect precision.

Safe and easy CI/CD

Docker app developers love pipelines

So your CI/CD machine spins up a clean VM for each test run? Just install MicroK8s at the top of your script for a crisp, clean K8s to run your tests.

Experience MicroK8s

Here's a quick intro video. Pause and copy commands straight from this text console.

The team behind MicroK8s

Microk8s is built by the Kubernetes team at Canonical. We work with public cloud K8s teams, and also have two K8s distributions of our own. MicroK8s is on-rails and opinionated, for the zero-ops experience. We also make Charmed Kubernetes for total control of all the permutations of Kubernetes components.

To get started with Docker Engine on Debian, make sure youmeet the prerequisites, theninstall Docker.

Prerequisites

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Debian orRaspbian versions:

• Debian Buster 10 (stable)
• Debian Stretch 9 / Raspbian Stretch

Install Docker On Arches

Docker Engine is supported on x86_64 (or amd64), armhf, and arm64 architectures.

Uninstall old versions

Older versions of Docker were called docker, docker.io, or docker-engine.If these are installed, uninstall them:

It's OK if apt-get reports that none of these packages are installed.

The contents of /var/lib/docker/, including images, containers, volumes, andnetworks, are preserved. The Docker Engine package is now called docker-ce.

Installation methods

You can install Docker Engine in different ways, depending on your needs:

• Most usersset up Docker's repositories and installfrom them, for ease of installation and upgrade tasks. This is therecommended approach, except for Raspbian.

• Some users download the DEB package andinstall it manually and manageupgrades completely manually. This is useful in situations such as installingDocker on air-gapped systems with no access to the internet.

• In testing and development environments, some users choose to use automatedconvenience scripts to install Docker.This is currently the only approach for Raspbian.

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you needto set up the Docker repository. Afterward, you can install and update Dockerfrom the repository.

Raspbian users cannot use this method!

For Raspbian, installing using the repository is not yet supported. You mustinstead use the convenience script.

Set up the repository

1. Update the apt package index and install packages to allow apt to use arepository over HTTPS:

2. Add Docker's official GPG key:

3. Use the following command to set up the stable repository. To add thenightly or test repository, add the word nightly or test (or both)after the word stable in the commands below. Learn about nightly and test channels.

   Note: The lsb_release -cs sub-command below returns the name of yourDebian distribution, such as helium. Sometimes, in a distributionlike BunsenLabs Linux, you might need to change $(lsb_release -cs)to your parent Debian distribution. For example, if you are using BunsenLabs Linux Helium, you could use stretch. Docker does not offer any guarantees on untestedand unsupported Debian distributions.

Install Docker Engine

This procedure works for Debian on x86_64 / amd64, armhf, arm64, and Raspbian.

1. Update the apt package index, and install the latest version of DockerEngine and containerd, or go to the next step to install a specific version:

   Got multiple Docker repositories?

   If you have multiple Docker repositories enabled, installingor updating without specifying a version in the apt-get install orapt-get update command always installs the highest possible version,which may not be appropriate for your stability needs.

2. To install a specific version of Docker Engine, list the available versionsin the repo, then select and install:

   a. List the versions available in your repo:

   b. Install a specific version using the version string from the second column, for example, 5:18.09.1~3-0~debian-stretch .

3. Verify that Docker Engine is installed correctly by running the hello-worldimage.

   This command downloads a test image and runs it in a container. When thecontainer runs, it prints an informational message and exits.

Docker Engine is installed and running. The docker group is created but no usersare added to it. You need to use sudo to run Docker commands.Continue to Linux postinstall to allow non-privilegedusers to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, first run sudo apt-get update, then follow theinstallation instructions, choosing the newversion you want to install.

Install from a package

If you cannot use Docker's repository to install Docker Engine, you can download the.deb file for your release and install it manually. You need to downloada new file each time you want to upgrade Docker.

1. Go to https://download.docker.com/linux/debian/dists/,choose your Debian version, then browse to pool/stable/, choose amd64,armhf, or arm64, and download the .deb file for the Docker Engineversion you want to install.

   Note: To install a nightly or test (pre-release) package,change the word stable in the above URL to nightly or test.Learn about nightly and test channels.

2. Install Docker Engine, changing the path below to the path where you downloadedthe Docker package.

   The Docker daemon starts automatically.

3. Verify that Docker Engine is installed correctly by running the hello-worldimage.

   This command downloads a test image and runs it in a container. When thecontainer runs, it prints an informational message and exits.

Docker Engine is installed and running. The docker group is created but no usersare added to it. You need to use sudo to run Docker commands.Continue to Post-installation steps for Linux to allownon-privileged users to run Docker commands and for other optional configurationsteps.

Upgrade Docker Engine

To upgrade Docker Engine, download the newer package file and repeat theinstallation procedure, pointing to the new file.

Install using the convenience script

Docker provides convenience scripts at get.docker.comand test.docker.com for installing edge andtesting versions of Docker Engine - Community into development environments quickly andnon-interactively. The source code for the scripts is in thedocker-install repository.Using these scripts is not recommended for productionenvironments, and you should understand the potential risks before you usethem:

• The scripts require root or sudo privileges to run. Therefore,you should carefully examine and audit the scripts before running them.
• The scripts attempt to detect your Linux distribution and version andconfigure your package management system for you. In addition, the scripts donot allow you to customize any installation parameters. This may lead to anunsupported configuration, either from Docker's point of view or from your ownorganization's guidelines and standards.
• The scripts install all dependencies and recommendations of the packagemanager without asking for confirmation. This may install a large number ofpackages, depending on the current configuration of your host machine.
• The script does not provide options to specify which version of Docker to install,and installs the latest version that is released in the 'edge' channel.
• Do not use the convenience script if Docker has already been installed on thehost machine using another mechanism.

Install Docker Ce Arch Linux

This example uses the script at get.docker.com toinstall the latest release of Docker Engine - Community on Linux. To install the latesttesting version, use test.docker.com instead. Ineach of the commands below, replace each occurrence of get with test.

Warning:

Always examine scripts downloaded from the internet beforerunning them locally.

If you would like to use Docker as a non-root user, you should now consideradding your user to the 'docker' group with something like:

Remember to log out and back in for this to take effect!

Warning:

Adding a user to the 'docker' group grants them the ability to run containerswhich can be used to obtain root privileges on the Docker host. Refer toDocker Daemon Attack Surfacefor more information.

Docker Engine - Community is installed. It starts automatically on DEB-based distributions. OnRPM-based distributions, you need to start it manually using the appropriatesystemctl or service command. As the message indicates, non-root users can'trun Docker commands by default.

Note:

To install Docker without root privileges, seeRun the Docker daemon as a non-root user (Rootless mode).

Upgrade Docker after using the convenience script

If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There is no advantage to re-running theconvenience script, and it can cause issues if it attempts to re-addrepositories which have already been added to the host machine.

Uninstall Docker Engine

1. Uninstall the Docker Engine, CLI, and Containerd packages:

2. Images, containers, volumes, or customized configuration files on your hostare not automatically removed. To delete all images, containers, andvolumes:

You must delete any edited configuration files manually.
