kubernetes使用不同的命令創建多個相同圖像的豆莢/部署

Question

我在單個豆莢內部部署了2個容器（container-test2和cloudsql-proxy）。

container-test2運行一個docker映像，它將[「my_app」，「arg1」，「arg2」]作爲CMD傳遞。我想用不同的參數組合運行這個容器的幾個實例。我也想在單獨的窗格中運行它們，以便我可以在節點上分發它們。我不完全確定如何做到這一點。

我可以成功運行這兩個容器，但我不知道如何使用不同參數進行container-test2複製，並使每個容器都在單獨的容器中啓動。

編輯：解

我解決它通過創建部署配置的多個拷貝到目錄「部署」，修改名稱和命令，然後運行：

kubectl創建-f部署/

1. 你不能讓individua l副本運行不同的參數，它們不會像「精確副本」那樣是副本。如果你想用不同的參數多次運行你的應用程序，你需要使用多個部署。

2. 複製的容器在其自己的Pod中運行，例如，應該有三個豆莢存在的部署擴展到三個重複
