Feeling really dumb here. Created a cluster with the following commands on my Macbook Pro M1 and am able to connect over localhost just fine, but when I try it on my Ubuntu desktop I can't connect. I've got Rancher Desktop installed and configured with docker/moby on both. 🧵

Hey, I want to use k3d in a Github action for e2e tests. Anyone have a preference on https://github.com/AbsaOSS/k3d-action vs https://github.com/nolar/setup-k3d-k3s ? AbsaOSS looks a bit more recent?

I am deploying a cluster with 3 node apple M1 macs, and noticed that “distributed cluster” was moved to milestone 5.5, hoping for this enhancement asap.

skaffold + k3d is unbeatable combo for CI / CD and e2e testing of helm charts very smoothly running on GH Actions and allows doing "crazy things" 😉

So I'm trying to deploy cert-manager on a bare k3d server, and I'm getting issues with cert-manager's ca-injector not being able to perform leader election, is this a known issue with k3d? I think I had it working before

Hi all I see this issue is closed https://github.com/k3d-io/k3d/issues/122 But I can't find related topic in docs https://k3d.io/v5.0.0/ Am I missing smth ?

Hi all I never used internal k3d traefik before, so encountered an issue when creating a new cluster with LB and traefik the

k3d cluster create

doesn't wait until traefik is up , so I manually must check if helm chart and CRDs are installed is there any way to improve this experience ?

Hello everyone! How can I add a private registry to an existing cluster? From the doc on the site, it's not clear if it's possible. Initially, I created a cluster with

--registry-config

flag.

05/11/2022, 1:26 AM

I added a register in the docker container

{name}-server-0

directly but wondering if there is another way.

Hey all--anyone know why when I create a cluster with one node with the

--host-alias

flag, that works… unless I restart the node, in which case the alias I configured earlier goes missing?

I've got an issue with k3d on ArchLinux with my firewalld configuratuion.

kubectl cluster-info

returned a valid config but

kubectl get pods

showed all bootstrap containers in

CreatingContainer

state.

Is it better to use k3s with multipass or docker (via k3d) on a Mac M1? Using multipass VMs seems a bit closer to how k8s is deployed in production as at least you can interact with the individual nodes. Just curious if anyone has noticed any advantages/disadvantages with either approach. Thanks!

👋🏻 k3d experts! I’m looking into k3d and found it interesting that it bundles an nginx container in front of k3s clusters by default. Can anybody explain the reasoning behind that design decision?

Hi there, I'm working with

k3d

and tilt.dev on a helmchart that requires

sysbox

and

CRI-O

is there anyway to get k3d to utilize a

CRI-O

runtime?

Good day, I am manually creating k3d cluster on a fresh AWS EC2 instance. 1. Installed docker, k3s, k3d. 2. Run k3d command to create cluster with 3 + 3 nodes (k3d cluster create my-cluster --servers 3 --agents 3). Issue- when performing kubectl get nodes, I assume to list all created k3d nodes, instead, I get EC2 instance. When running k3d node ls, I clearly see all created nodes. Question- how can I work in the k3d cluster, example, install helm charts in cluster instead of on EC2 instance. Many thanks!

Are network policies applied/in effect by default with k3d when I start the cluster with

k3d cluster create $CLUSTER_NAME

and without any configuration files?

Hi folks. My team is intending to adopt k3d for a local development environment, and we have to deploy infrastructure tools such as PostgreSQL, Kafka, Prometheus and so on. I’ve already been able to deploy all of them, but I’m struggling to enable access from the host machine (esp. kafka). I’m wondering if somebody here did it before and if so, could they point me towards the right path? Normally what I would do is to setup a load balancer, but this doesn’t work, I suspect is because of Docker for Mac. Thanks in advanced and have a nice day.

Hi all, I try to switch from Kind to k3d. But I fail in the very beginning because I am using flux to deploy my stuff. If I deploy the following manifest:

apiVersion: <http://source.toolkit.fluxcd.io/v1beta1|source.toolkit.fluxcd.io/v1beta1>

kind: HelmRepository metadata: name: vault spec: interval: 5m url: https://helm.releases.hashicorp.com I got the following error from flux:

I have no glue what's going wrong there in k3d. Can anybody help me please in this issue Thanks a lot Klaus

I'm using https://k3d.io/v5.4.1/usage/exposing_services/ and

k3d cluster create $CLUSTER_NAME -p "8081:3000@loadbalancer"

to create my local cluster and get something exposed. This works well, but now I'd like to expose two things. Is that possible? Can I do something like

k3d cluster create $CLUSTER_NAME -p "8081:3000,8082:8000@loadbalancer"

melodic-market-42092

06/24/2022, 10:00 AM

I'm doing

k3d cluster create $CLUSTER_NAME \
    -p "8081:3000@loadbalancer" \
    -p "8082:8000@loadbalancer" \
    -p "8086:8086@loadbalancer" \
    -p "8087:2746@loadbalancer"

to expose a few things from my k3d cluster. The first three of those work, but the last one just.. doesn't. I'm struggling to figure out why. If I do a port-forward to the service, then things work as expected. The ingress and service for the fourth entry there (8087:2746) looks exactly similar to the ingress'es for the other three 🤔 The application behind 2746 is https://argoproj.github.io/argo-workflows/argo-server/. Any hints anybody could give on this? Hopefully someone has seen this before.

What I don't get is how the configs get written into the

/etc/confd/values.yaml

file. Is this a shared volume between the nodes or is there some other mechanism in play?

Hello Looks like I found a regression in 5.4.4 1. create k3d cluster 2. deploy smth there - not sure what because I deploy few tools includinig custom traefik 3. restart PC / laptop 4. docker container from this image rancher/k3s:v1.23.6-k3s1 is constantly failing to start 5. this causes kubectl to work unstable, with lags etc ( apparetnly because API is unavailable ) 5.4.3 works fine

hi, I think it may have come up many times, still trying one more time. Is it possible anyway to make k3d use local docker cache via any proxy or anything else which makes my life easier rather than importing images everytime into the cluster?

k3d is mentioned in a 1st place https://traefik.io/blog/top-5-open-source-tools-local-development-kubernetes/?utm_[…]&utm_medium=social&utm_source=twitter&hss_channel=tw-4890312130

If I modify my

/etc/hosts

like this:

localhost       myapp.local

And have an ingress like this:

spec:
  rules:
    - host: myapp.local

And run k3d like this:

k3d cluster create $CLUSTER_NAME \
    -p "80:80@loadbalancer" \

Should I then be able to reach the service that my ingress points to by going to http://myapp.local in the browser?
