## Problem

Node in NotReady state, Nodeletd Phases output failing, with missing images.

{% tabs %}
{% tab title="Nodelet phases" %}

```javascript
{"L":"INFO","T":"2023-12-01T07:01:51.885Z","C":"command/command.go:120","M":"[2023-12-01 07:01:51] docker: Error response from daemon: manifest for localhost:5100/kube-proxy:v1.20.11 not found: manifest unknown: manifest unknown."}
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Edge Cloud (PEC) - Airctl v-5.3.0-2075501

## Solution

Manually push the Docker registry from DU Host to the DU VM.

Procedure to manually push the images:

Verify if the DU host has the required docker registry tar available at `/opt/pf9/airctl/imgs/docker-imgs-{airctl-version}.tar.gz`.

{% tabs %}
{% tab title="Tar on DU Host" %}

```javascript
# la /opt/pf9/airctl/imgs/docker-imgs-v-5.3.0-2075501.tar.gz
```

{% endtab %}
{% endtabs %}

Once tar is available for the required Airctl version, proceed with the below steps to push the Docker registry from the DU host to DU VM.

1. Execute the push-images command as shown below:

{% tabs %}
{% tab title="On DU Host" %}

```javascript
# /opt/pf9/airctl/airctl --config /opt/pf9/airctl/conf/airctl-config.yaml advanced-du push-images --img-tar /opt/pf9/airctl/imgs/docker-imgs-v-5.3.0-2075501.tar.gz --verbose
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="On success" %}

```javascript
Pushing images 100% |████████████████████████████████████████|  [12m42s:0s]2023-06-23T08:01:18.873Z info  finish progressbar: success

2023-06-23T08:01:18.960Z info closing tunnel
registry push done
```

{% endtab %}
{% endtabs %}

2. Verify if the images are available now.

{% tabs %}
{% tab title="DU VM - Docker path" %}

```javascript
[root@airctl-1-2683490-924.pf9.localnet ~(admin)]# cd /opt/pf9/images/data/docker/registry/v2/
[root@airctl-1-2683490-924.pf9.localnet v2(admin)]# ll
total 4
drwxr-xr-x  3 root root   20 Jun 23 07:48 blobs
drwxr-xr-x 32 root root 4096 Jun 23 08:01 repositories
[root@airctl-1-2683490-924.pf9.localnet v2(admin)]# du -sch *
4.0G	blobs
4.5M	repositories
4.0G	total
```

{% endtab %}
{% endtabs %}

```
  OR
```

{% tabs %}
{% tab title="Curl request" %}

```javascript
[root@airctl-1-2683490-924.pf9.localnet v2(admin)]# curl http://localhost:5100/v2/_catalog | jq
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1438  100  1438    0     0  43255      0 --:--:-- --:--:-- --:--:-- 43575
{
  "repositories": [
    "addon-resizer",
    "autoscaling/addon-resizer",
    "busybox",
    "calico/cni",
    .
    . 
     // multiple images should list here
    .
    "prometheus-operator/prometheus-operator",
    "python"
  ]
}
```

{% endtab %}
{% endtabs %}

3. Once confirmed with the above output, docker images are successfully extracted to the DU VM.
4. Restart the Nodeletd stack as mentioned in <https://platform9.com/kb/kubernetes/how-to-restart-pmk-stack->
