I am really not sure whether you know Telugu or not ఇంత in-depth kubernetes knowledge చాలా ఓపికగా చాలా ఎక్కువ విషయాన్ని చెబుతూ చెప్పినా యూట్యూబ్ మీరు ఒక్కరే Thankyou so much.... Expecting more in the future...

Should we have to download & install "ctr" individually or it is already attached with containerd ??? I made a k8s cluster using containerd as a container runtime, but dont understand how to see containers in worker node.. Please help me to know....

@learnwithgvr 9 месяцев назад

Ctr is already available

@k8s.junior Год назад

Hi. , How can we delete the unused images and snapshots and content inside /var/lib/containerd because its taking too much of space . Is there any command like docker image prune or system prune , if anything let us know .

@learnwithgvr Год назад

Try these... removes all unsed images, stopped containers, volumes etc ctr --namespace xyz containers prune ctr --namespace xyz images prune ctr --namespace xyz content prune Pls subscribe and like

@albertadiprasetyo5284 3 дня назад

@@learnwithgvr Hi venkata, my ctr only have content prune option available. I cannot do image prune or container prune. I wonder why ? If i just use content prune does it prune unused image, containers and volume ?

Hi Can anyone tell me how we can run ctr container as non root user?

@learnwithgvr Год назад

containerd is runtime and ctr is cli tool based on the GRPC api for debugging troubleshooting etc. In order to run as non root user, you need harden at docker image creation level, then container orchestration level, implement various CKS security hardening mechanisms. I hope you get it what i mean.

@adarshrao4393 Год назад

@@learnwithgvr well the problem is, in case of docker cli, in order to run container as non root user, i used to create docker group and add the user to the group(in host) and then create same user in dockerfile and then run container with -u , but im not sure how to do the same using ctr cli.

@learnwithgvr Год назад

@@adarshrao4393got it. ContainerD is completely loosely coupled, can achieve anything. for your use case -uidmap --gidmap, --privileged=false to be used with ctr. refer ctr run -h for all commands Alternatively you can achieve using nerdctl or RootlessKit. Refer github.com/containerd/containerd/blob/main/docs/rootless.md rootlesscontaine.rs/ github.com/containerd/nerdctl Hope it helps

@adarshrao4393 Год назад

@@learnwithgvr i need to strictly use ctr cli, i knw we can do it with nerdctl, but anyways this will help me. Thanks a lot😀.
