Are you maybe behind a firewall or proxy?
Can you pull that image with plain docker?
r
I manually pulled image, what should I do next to include that so this error get resolved
I'm in office laptop trying to do local setup using k3d tried everything related to it with the help of chatGPT and claude but couldn't able to resolve. I also tried pull manually that image and apply it to cluster but still same issue, Any help appreciated.
w
Are you maybe behind a firewall or proxy? What version of k3d and K3s are you using?
r
Yes it maybe behind proxy config as it's corporate laptop for security purpose. k3d version v5.8.1 k3s version v1.31.4-k3s1 (default)

thanks, may i know for this command from where I can find certs.crt and yourcert.crt mentioned below?
Copy code
Mounting the CA Certificate from your host into the node containers at start time via k3d cluster create --volume /path/to/your/certs.crt:/etc/ssl/certs/yourcert.crt
c
those are YOUR certs. They are wherever you find your org’s CA certs.
r
oh got it, is this should be only in /etc/ssl/certs/yourcert.crt path I need to copy? As I don't have root level access on my macbook, but I'm using the helm chart is there way I can do the same there?
w
What helm chart? This is a k3d flag you use when creating the cluster in the first place 👍
r
Copy code
k3d cluster create feature-flag-demo \
  --volume ~/corporate.com.cer:/etc/ssl/certs/corporate-ca.crt \
--registry-config ~/.k3d/registries.yaml
I tried creating cluster with above command but still same issue it's output looks like below
