support for windows containers-as-workspaces #6657
Description
we've received requests for running windows containers as Coder workspaces. in my attempts to POC this use-case, i've run into issues with how containerd executes powershell commands/scripts as part of the entrypoint command in the kubernetes_pod spec in Terraform. related issue: containerd/containerd#5067
versions
- host: GCP Windows LTSC with containerd (Windows Server 2019 Datacenter)
- runtime:
containerd://1.6.13-gke.1 - k8s provider:
2.12.1
error
Error: failed to start containerd task "coder-container":
hcs::System::CreateProcess coder-container: The system cannot find the file specified.: unknowntests
1. execute powershell against the init_script terraform object
resource "kubernetes_pod" "main" {
container {
image = "docker.io/stefanscherer/node-windows:latest"
command = ["powershell.exe", "-NoExit", "-Command", coder_agent.main.init_script]
}
}2. mount the init_script as a volume, execute the file via powershell
resource "kubernetes_pod" "main" {
spec {
container {
image = "docker.io/stefanscherer/node-windows:latest"
command = ["powershell.exe", "-NoExit", "-Command", "C:\\coder_init\\init.ps1"]
}
volume_mount {
mount_path = "C:\\coder_init"
name = "coder-init-script"
}
volume {
name = "coder-init-script"
secret {
secret_name = "coder-init-script"
}
}
}
resource "kubernetes_secret" "init_script" {
metadata {
name = "coder-init-script"
namespace = "oss"
}
type = "Opaque"
data = {
"init.ps1" = base64encode(coder_agent.coder.init_script)
}
}3. set the SHELL & ENTRYPOINT in the Dockerfile
FROM stefanscherer/node-windows:latest
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]
ENTRYPOINT ["powershell.exe"]resource "kubernetes_pod" "main" {
container {
image = "ericpaulsen/windows-test:latest"
command = ["C:\\coder_init\\init.ps1"]
}
}any feedback, troubleshooting ideas are appreciated.
