Authenticate to a registry and persist credentials

Usage: ocx login [OPTIONS] [REGISTRY]

Arguments:
  [REGISTRY]
          Registry hostname (e.g. `ghcr.io`, `registry.example.com`). Optional - falls back to `OCX_DEFAULT_REGISTRY`

Options:
  -u, --username <USERNAME>
          Username for the registry. Prompted when omitted on a TTY

      --password-stdin
          Read password/token from stdin. Required in non-interactive contexts

      --allow-insecure-store
          Allow plaintext fallback to `~/.docker/config.json` `auths` when no native helper is configured. Default: refuse, exit `ConfigError(78)` with install hint.
          
          Governs credential STORAGE, not transport. It does not enable plain HTTP; to reach a registry over HTTP, set `insecure = true` under `[registries."<host>"]` or add the host to `OCX_INSECURE_REGISTRIES`.

      --verify
          Verify the operation against the registry before committing it (default)

      --no-verify
          Skip verification

  -h, --help
          Print help (see a summary with '-h')
