分析
主要是這個(gè)報(bào)錯(cuò)信息很奇怪，一開始沒(méi)有往掛載目錄上的問(wèn)題去想，沒(méi)想到會(huì)是這個(gè)方向的上的錯(cuò)誤
https://github.com/kubernetes/kubernetes/issues/63477
使用 configmap 掛載目錄的時(shí)候掛載到了 /etc 目錄下面，而這個(gè)目錄是 read-only 的兼雄，所以報(bào)錯(cuò)了梧税。重新選擇掛載目錄或者掛載單個(gè)文件就可以了。
volumeMounts:
- name: config-volume
mountPath: /etc/conf.yaml
subPath: conf.yaml
其實(shí)建議還是最好不要掛 etc 目錄侵蒙，后面可能也會(huì)有問(wèn)題的
