How to Install Containerd on Fedora 36 / Fedora 35 | Holhol24

7

containerd is an industry-standard container runtime that manages the container lifecycle. It handles symbol switch and garage, container execution and supervision, low-level garage and community attachments, and so on.

containerd is among the container runtimes that works with Kubernetes, and it’s neatly suited in your atmosphere because of its simplicity.

Here, we will be able to see how you can set up containerd on Fedora 36 / Fedora 35.

Install Containerd on Fedora

You can set up containerd the usage of legit binaries or from the Docker repository.

Install Containerd Using Official Binaries

Install Containerd

First, obtain the most recent model of containerd binary from GitHub and extract the recordsdata to the /usr/native/ listing.

wget https://github.com/containerd/containerd/releases/obtain/v1.6.6/containerd-1.6.6-linux-amd64.tar.gz

sudo tar Czxvf /usr/native containerd-1.6.6-linux-amd64.tar.gz

Then, obtain the systemd carrier document and set it up so you’ll be able to set up the carrier by means of systemd.

wget https://uncooked.githubusercontent.com/containerd/containerd/major/containerd.carrier

sudo mv containerd.carrier /usr/lib/systemd/gadget/

sudo restorecon -Rv /usr/lib/systemd/gadget/

Finally, get started the containerd carrier the usage of the beneath command.

sudo systemctl daemon-reload

sudo systemctl permit --now containerd

Install runC

runC is a CLI device for spawning and operating packing containers on Linux in keeping with the OCI specification.

Download the most recent model of runC from GitHub and set up it as /usr/native/sbin/runc.

wget https://github.com/opencontainers/runc/releases/obtain/v1.1.3/runc.amd64

sudo set up -m 755 runc.amd64 /usr/native/sbin/runc

Containerd configuration for Kubernetes

containerd makes use of a configuration document config.toml for dealing with its demons. When putting in containerd by means of legit binaries, you’re going to now not get the configuration document. So, generate the default configuration document the usage of the beneath instructions.

sudo mkdir -p /and so on/containerd/

containerd config default | sudo tee /and so on/containerd/config.toml

If you propose to make use of containerd because the runtime for Kubernetes, configure the systemd cgroup driving force for runC.

sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/g' /and so on/containerd/config.toml

Next, use the beneath command to restart the containerd carrier.

sudo systemctl restart containerd

Using Docker Repository

Docker provides the containerd containerd.io bundle within the .deb structure throughout the Docker repository. So, set up the specified applications for containerd set up.

Set up Docker Repository

Add the Docker repository to the gadget through operating the beneath command.

sudo dnf -y set up dnf-plugins-core

sudo dnf config-manager --add-repo https://obtain.docker.com/linux/fedora/docker-ce.repo

Install Containerd

Then, set up containerd the usage of the dnf command.

sudo dnf set up -y containerd.io

Next, get started the containerd carrier

sudo systemctl permit --now containerd

Then, take a look at the standing of the containerd carrier.

sudo systemctl standing containerd

Containerd configuration for Kubernetes

containerd makes use of a configuration document config.toml for managing demons. For Kubernetes, you want to configure the Systemd crew driving force for runC.

cat <

Then, permit CRI plugins through commenting out disabled_plugins = ["cri"] within the config.toml document.

sudo sed -i 's/^disabled_plugins =/#disabled_plugins =/g' /and so on/containerd/config.toml

Next, use the beneath instructions to restart the containerd carrier.

sudo systemctl restart containerd

Install CNI Plugins For Containerd / Kubernetes

For the container to run, you want to put in CNI plugins. In Fedora, CNI plugins get put in within the /usr/libexec/cni listing through default; this location isn't a normal for CNI plugins. So, make a symbolic hyperlink to the usual CNI listing /choose/cni/bin.

sudo dnf set up -y containernetworking-plugins

sudo mkdir /choose/cni && sudo ln -sf /usr/libexec/cni/ /choose/cni/bin

Next, restart the containerd carrier.

sudo systemctl restart containerd

Then, take a look at the standing of the containerd carrier.

sudo systemctl standing containerd

Install nerdctl (CLI)

nerdctl is a Docker-compliant command-line interface for containerd. It isn't a part of the core bundle, and you will set up the most recent model of nerdctl from GitHub.

wget https://github.com/containerd/nerdctl/releases/obtain/v0.21.0/nerdctl-0.21.0-linux-amd64.tar.gz

sudo tar Cxzvf /usr/native/bin nerdctl-0.21.0-linux-amd64.tar.gz

A pattern command:

sudo nerdctl run -d -p 80:80 --name=nginx nginx
