File upload does not work with directories with ":" in their names

[martinkou]

Let's say I have a directory structure like this, which I wish to copy to a target host..

$ tree gpu-workstation/

gpu-workstation/
├── etc
│   └── k0s
│       ├── certs.d
│       │   └── gpu-workstation:30101
│       │       ├── hosts.toml
│       │       └── ca.pem
│       └── containerd.d
│           └── registry.toml
└── var
    └── lib
        └── tailscale
            └── tailscaled.state

Which I then put into k0sctl.yaml like this..

spec:
  hosts:
  ...
  - ssh:
      address: 100.92.34.7
      user: martin_kou
      port: 22
      keyPath: null
    role: worker
    files:
      - name: test
        src: gpu-workstation
        dstDir: /

The directory gpu-workstation:30101 would cause the file upload to always fail with an "invalid path" log entry. e.g.

If I remove any directory with ":" from the source files, then the upload would succeed. Unfortunately, in this particular case I actually need the "gpu-workstation:30101" to be named in that particular way.

That's strange.

It looks like the command install -m 0644 /dev/null /etc/k0s/certs.d/gpu-workstation:30101/hosts.toml fails which creates an empty file with 0644 permissions.

It looks like it didn't use sudo but I can't understand how that could happen.

I need to try this out myself.

I think the colon is a red herring, this is probably the same issue I had in https://github.com/k0sproject/k0sctl/issues/638
