### 2 Configuration and initialize the bootstrap
#### 2.5 Run the ansible bootstrap
問題1：
MODULE FAILURE incorrect password attempt
解決：需使用root權限執行
`$sudo su root`

問題2：
無法找到localhost.yml內對ip與gateway相關的config
解決：將localhost.yml存到~

問題3: Download images failed
原因為ip與gateway設定有誤，導致無法連至internet下載所需之image
解決方法: 為配置正確之ip與gateway設定

問題4: Unable to install through ansible in stx 5.0 due to kubernetes helm being deleted
儘管成功連至internet但仍無法成功下載https://gcr.io/v2/kubernetes-helm/tiller/manifests/v2.16.1 此image，原因為此項目已被修改，導致無法尋獲
解決方法: 需更改 /usr/share/ansible/stx-ansible/playbooks/roles/common/load-images-information/vars/k8s-v1.18.1/system-images.yml 之目標下載檔案與checksum

# System images that are pre-pulled and pushed to local registry
n3000_opae_img: docker.io/starlingx/n3000-opae:stx.4.0-v1.0.0
-tiller_img: gcr.io/kubernetes-helm/tiller:v2.16.9

kubernetes_entrypoint_img: quay.io/stackanetes/kubernetes-entrypoint:v0.3.1
calico_cni_img: quay.io/calico/cni:v3.12.0

更改後需清除 system-images.yml~與.system-images.yml.un兩個檔案以免發生後續錯誤

rm -rf system-images.yml~ && .system-images.yml.un

以及更改 /usr/share/ansible/stx-ansible/playbooks/roles/common/armada-helm/templates/aramada-overrides.yml.j2 之目標下載檔案與checksum

  # Configure sane node labels values that work with armada node selector.
  # Helm v3 validation prevents null overrides.

更改後需清除 aramada-overrides.yml.j2~

rm -rf aramada-overrides.yml.j2~

完成後應顯示:

架設虛擬網卡
Interface not found

外接usb轉RJ45
同樣為Interface not found

而電腦原始網卡enp0s25則能正常對其進行配置

將OAM_IF網卡改成電腦內wifi網卡即可成功
