Running inside Kubernetes

[felipeconti]

Is it possible to run it in a cluster Kubernetes?

I got this error when I tried:

❯ Starting Windows for Docker v2.10...

I have zero experience with Kubernetes, so hopefully another user who knows how to do it can help you.

Or maybe this pull-request: https://github.com/dockur/windows/pull/304/files

you can substitute --cap-add NET_ADMIN to --privileged but it s insecure. There isn't any workaround for the moment, other than that.

Got a problem on my kubernetes :

qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000007H:EDX.invtsc [bit 8]
qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000007H:EDX.invtsc [bit 8]
BdsDxe: failed to load Boot0002 "UEFI QEMU QEMU HARDDISK " from PciRoot(0x0)/Pci(0xA,0x0)/Scsi(0x0,0x0): Not Found
BdsDxe: loading Boot0001 "UEFI QEMU QEMU CD-ROM " from PciRoot(0x0)/Pci(0x5,0x0)/Scsi(0x0,0x0)
BdsDxe: starting Boot0001 "UEFI QEMU QEMU CD-ROM " from PciRoot(0x0)/Pci(0x5,0x0)/Scsi(0x0,0x0)

so best luck to youuuu as well ^^

@thomasblot1 That error is when your CPU doesnt support flags for Hyper-V, you can add the environment variable: HV: "N" to disable Hyper-V enlightments.

I have now added an example Kubernetes manifest, see:
