набор состояний minikube mongodb с постоянным томом для 3 реплик

/ 29 сентября 2019

Pod не запускается, и мне сложно отлаживать его из-за моего ограниченного опыта. Я также подключил том с локального компьютера к мини-кубу vm следующим образом: minikube start --cpus 4 --memory 8192 --mount-string="/data/minikube:/data" --mount

Любая помощь будет принята с благодарностью.
