Antaranya:

Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for gcr.io/google_containers/pause:2.0, this may be because there are no credentials on this request.  details: (unable to ping registry endpoint https://gcr.io/v0/\nv2 ping attempt failed with error: Get https://gcr.io/v2/: dial tcp 74.125.204.82:443: getsockopt: connection refused\n v1 ping attempt failed with error: Get https://gcr.io/v1/_ping: dial tcp 74.125.204.82:443: getsockopt: connection refused)

Tidak sukar untuk melihat gcr.io tidak boleh diakses
Terdapat penyelesaian berikut:

1. Naik dinding

2. Ubah suai fail hos

3. Muat turun bekas "pause:2.0" daripada sumber lain, dan kemudian tandainya sebagai "gcr.io/google_containers/pause:2.0"

gcr.io disekat, anda boleh menambah parameter kubelet pada --pod-infra-container-image untuk menentukan cermin domestik.

Kami mengalihkan imej ke registry.aliyuncs.com/archon/pause-amd64:3.0 dan anda boleh menggunakannya.
