Проверю конфиг Docker и подскажу, почему он пытается вызвать `docker-credential-desktop`, которого нет в `PATH`, а затем дам безопасный фикс под Linux.

**Fixing Docker credential issue**

It sounds like I need to help with a Docker credential helper issue that the user mentioned. I should consider checking the `/.docker/config.json` file since it might be straightforward. I’m thinking about using shell commands to inspect it, but it’s likely simpler than that. I don't think I need to choose a mode or do file operations like "ls." Instead, I'll focus on directly reading the config file using the appropriate method. I'll start by updating my commentary first.

Причина уже видна: в `~/.docker/config.json` указан глобальный `credsStore: "desktop"`, это настройка от Docker Desktop, а у вас под Linux helper `docker-credential-desktop` не установлен. Проверю, есть ли у вас другой доступный helper, чтобы предложить лучший вариант.

**Exploring fix options**

I’m thinking about how to explain a fix. Maybe I should use the shell to check if docker-credential-pass or secretservice exists; that could provide some insight. I could use the "which" command in the shell to help locate these credentials. It seems like a good way to determine if they're installed or if there could potentially be an issue. I'll pursue this approach to figure things out!

Проблема в `~/.docker/config.json`: там стоит

```json
{
  "auths": {
    "docker-local-devsecops.art.lmru.tech": {}
  },
  "credsStore": "desktop"
}
```

`credsStore: "desktop"` заставляет Docker вызывать `docker-credential-desktop`, а у вас его нет. На Linux это обычно остаток от Docker Desktop.

Исправление:
1. Удалите строку `"credsStore": "desktop"` из `~/.docker/config.json`.
2. Повторите `docker pull`.

Быстрый вариант:
```bash
cp ~/.docker/config.json ~/.docker/config.json.bak
python - <<'PY'
import json, pathlib
p = pathlib.Path.home() / ".docker" / "config.json"
data = json.loads(p.read_text())
data.pop("credsStore", None)
p.write_text(json.dumps(data, indent=2) + "\n")
PY
```

Потом:
```bash
docker pull docker-security.art.lmru.tech/kube-state-metrics/kube-state-metrics:2.18.0
```

Если registry требует авторизацию, после этого выполните:
```bash
docker login docker-security.art.lmru.tech
```

Если хотите, могу сразу поправить `~/.docker/config.json` за вас.

**Considering config edits**

I’m thinking about advising on editing the config. I could suggest a command to remove credsStore and ask if the user wants help fixing it. But since they didn’t explicitly ask to change files, maybe I should avoid editing directly. I might include manual steps instead. It’s important to note that if they need authentication, it’ll store credentials plainly in the config after removing credsStore. I should keep it concise.
