If sprites are in k8s configMap, image names get garbled

[nyurik]

SVG files could be stored as binary blobs in the kubernetes' ConfigMap, and bound to Martin using config example below. Viewing files by connecting to the pod seem ok, but all files are actually symlinks (which should be ok).

/ # ls /app/sprites/foobar
foo.svg           bar.svg

/ # ls -alh /app/sprites/foobar
total 12K    
drwxrwxrwx    3 root     root        4.0K May 17 17:57 .
drwxr-xr-x    3 root     root        4.0K May 17 17:57 ..
drwxr-xr-x    2 root     root        4.0K May 17 17:57 ..2024_05_17_17_57_51.390489675
lrwxrwxrwx    1 root     root          31 May 17 17:57 ..data -> ..2024_05_17_17_57_51.390489675
lrwxrwxrwx    1 root     root          18 May 17 17:57 foo.svg -> ..data/foo.svg
lrwxrwxrwx    1 root     root          22 May 17 17:57 bar.svg -> ..data/bar.svg

The sprite json file on the other hand is incorrectly generated - http://.../sprite/foobar.json:

{
  "..2024_05_17_17_57_51.390489675/foo": {
    "height": 84,
    "pixelRatio": 1,
    "width": 85,
    "x": 170,
    "y": 0
  },
  "..2024_05_17_17_57_51.390489675/bar": {
    "height": 85,
    "pixelRatio": 1,
    "width": 85,
    "x": 0,
    "y": 0
  }
}

The catalog is also showing incorrect images, and they are duplicated?

{
  "sprites": {
    "foobar": {
      "images": [
        "..2024_05_17_17_57_51.390489675/foo",
        "..2024_05_17_17_57_51.390489675/foo",
        "..2024_05_17_17_57_51.390489675/foo",
        "..2024_05_17_17_57_51.390489675/bar",
        "..2024_05_17_17_57_51.390489675/bar",
        "..2024_05_17_17_57_51.390489675/bar"
      ]
    }
  }
}
