kandi X-RAY | containerd Summary
containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc. containerd is a member of CNCF with 'graduated' status. containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users.

I have a problem installing docker on my virtual machine. I have followed the steps below:
1. Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:
sudo apt-get remove docker docker-engine docker.io containerd runc
2. Update the apt package index
sudo apt-get update
3. install packages to allow apt to use a repository over HTTPS:

Answered 2021-Aug-09 at 12:48Make sure the content of the /etc/apt/sources.list.d/docker.list
corresponds to the output of the command in the documentation, bullet #3.
At the time of this writing executing the command on my Ubuntu 20.04 LTS results in the following content of the docker.list file:
deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu focal stable
which seems to be different from that of yours.
QUESTION
I am running into the following error when starting up containers on my Raspberry Pi 3B on Raspbian Buster:
...ANSWER
Answered 2022-Mar-04 at 17:33I was able to resolve this, unfortunately I won't be able to find out why this happened.
I tried removing and installing docker-ce
and dependencies again. I wasn't able to remove due to containerd.service
not stopping. I found it was set to always restart, which would normally make sense. I then ran sudo systemctl disable docker containerd
and rebooted. I confirmed those services were no longer running by following journalctl output, looking for the usual restarting and core-dump errors from docker
and containerd
.
I ran sudo apt remove docker-ce
and sudo apt autoremove
again, then ran docker's get-docker.sh
which reinstalled docker. I then ran sudo systemctl enable docker containerd
and sudo systemctl start docker containerd
. Docker is the same version it was before and the hello-world container and other containers of mine that wasn't previously running is now running successfully.

I have installed using instructions at this link for the Install NGINX using NodePort option.
When I do ks logs -f ingress-nginx-controller-7f48b8-s7pg4 -n ingress-nginx
I get :
ANSWER
Answered 2022-Mar-04 at 16:49I have installed using instructions at this link for the Install NGINX using NodePort option.
The problem is that you are using outdated k0s documentation:
https://docs.k0sproject.io/v1.22.2+k0s.1/examples/nginx-ingress/
You should use this link instead:
https://docs.k0sproject.io/main/examples/nginx-ingress/
You will install the controller-v1.0.0
version on your Kubernetes cluster by following the actual documentation link.

I have kubernets cluster in gcp with docker container runtime. I am trying to change docker container runtime into containerd. Following steps shows what I did.
- New node pool added ( nodes with containerd )
- drained old nodes
Once I perform above steps I am getting " Pod is blocking scale down because it has local storage " warning message.

Answered 2022-Feb-10 at 04:01You need to add the once annotation to POD so that cluster autoscaler can remove that POD from POD safe to evict.

Answered 2022-Feb-01 at 07:59Your actual ls
command piped to xargs
is seen as a single argument where file names are separated by null bytes (shortly said... see for example this article for a better in-depth analyze). If your version of xargs
supports it, you can use the -0
option to take this into account:

Answered 2022-Jan-29 at 20:57I'm going to assume that you used the Console to create your task definitions, because I saw the same behavior (and didn't expect it). The documentation says this:
Although you can also specify CPU and memory at the container level for Fargate tasks, this is optional. Most use cases are satisfied by only specifying these resources at the task level
I first created a task definition that specified CPU/memory at the task level. When I ran it, I saw the same output as you, and this is what the task definition looked like (irrelevant information omitted):
QUESTION
I am at a complete loss and really freaking out, because this project of mine was close to being done. I will give out a bounty for the answer that helps me (when I can). I am desperate, please help.
I have an Elastic Beanstalk project that has been working fine for literally months. Today, I decide to enable and disable a port listener as seen in the photo below:
I enabled port 80
and then the website stopped working. So I was like "oh crap, I will change it back". But guess what? It is still broken. The code has not changed whatsoever, but the application is now broken and I am freaking out.
I have restarted the app servers, rebuilt the environment and nothing. I can't even access the environment site by clicking Go to environment
. I just see a Bad Gateway
message on screen. The health status of the environment when first deployed is OK
and then quickly goes to Severe
.
If my code has not changed, what is the deal here? How can I find out what is going on here? All I changed was that port, by enabling and then disabling again.
I have already come across this question: Question and I am already doing this. This environment variable is on my application.properties
file like this:
server.port=5000
and its been like this for months and HAS ALREADY been working. So this can't be the reason that it broke today. I even tried adding it directly to the environment variables in Elastic Beanstalk console and same result, still getting 502 Bad Gateway.
I also have a path for the health-check configured and this has not changed in months.
Here are the last 100 lines from my log file after health status goes to Severe

ANSWER
Answered 2022-Jan-27 at 17:18Okay, so I decided to just launch a new environment using the same exact configuration and code and it worked. Looks like Elastic Beanstalk environments can break and once that happens, there is no fixing it apparently.
QUESTION
I'm fairly new to docker and I'm trying to run some minecraft containers, however they don't seem to be honoring the cpu limits I'm setting. As you can see in the commented out portions, i'v also tried using v3. No matter what limit I set, the container shows up to 400% cpu usage in docker stats. It is a 4cpu virtual machine hosted with Oracle, running Ubuntu.
Is there any other way to enforce this limit?

Something wrong happend with my RPi 4 cluster based on k3sup.
Everything works as expected until yesterday when I had to reinstall master node operating system. For example, I have a redis installed on master node and then some pods on worker nodes. My pods can not connect to redis via DNS: redis-master.database.svc.cluster.local
(but they do day before).
It throws an error that can not resolve domain when I test with busybox like:
...ANSWER
Answered 2022-Jan-16 at 15:05There was one more thing that was not mentioned. I'm using OpenVPN with NordVPN server list on master node, and use a privoxy for worker nodes.
When you install and run OpenVPN before running kubernetes master, OpenVPN add rules that block kubernetes networking. So, coredns does not work and you can't reach any pod via IP as well.
I'm using RPi 4 cluster, so for me it was good enough to just re-install master node, install kubernetes at first and then configure openvpn. Now everything is working as expected.
It's good enough to order your system units by adding After
or Before
in service definition. I have VPN systemd service that looks like below:
