- Problem: inside the container, the certificate of the corporate proxy cannot be validated
- Possible Solution: 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`
- Issue: [rancher/k3d#535](https://github.com/rancher/k3d/discussions/535#discussioncomment-474982)
### Spurious PID entries in `/proc` after deleting `k3d` cluster with shared mounts
- When you perform cluster create and deletion operations multiple times with **same cluster name** and **shared volume mounts**, it was observed that `grep k3d /proc/*/mountinfo` shows many spurious entries
- Problem: Due to above, at times you'll see `no space left on device: unknown` when a pod is scheduled to the nodes
- If you observe anything of above sort you can check for inaccessible file systems and unmount them by using below command (note: please remove `xargs umount -l` and check for the diff o/p first)
- `diff <(df -ha | grep pods | awk '{print $NF}') <(df -h | grep pods | awk '{print $NF}') | awk '{print $2}' | xargs umount -l`
- As per the conversation on [rancher/k3d#594](https://github.com/rancher/k3d/issues/594#issuecomment-837900646) above issue wasn't reported/known earlier and so there are high chances that it's not universal.
