kubernetes使用不同的命令创建多个相同图像的豆荚/部署

Question

我在单个豆荚内部部署了2个容器（container-test2和cloudsql-proxy）。

container-test2运行一个docker映像，它将[“my_app”，“arg1”，“arg2”]作为CMD传递。我想用不同的参数组合运行这个容器的几个实例。我也想在单独的窗格中运行它们，以便我可以在节点上分发它们。我不完全确定如何做到这一点。

我可以成功运行这两个容器，但我不知道如何使用不同参数进行container-test2复制，并使每个容器都在单独的容器中启动。

我解决它通过创建部署配置的多个拷贝到目录“部署”，修改名称和命令，然后运行：

kubectl创建-f部署/

Answer 1

1. 你不能让individua l副本运行不同的参数，它们不会像“精确副本”那样是副本。如果你想用不同的参数多次运行你的应用程序，你需要使用多个部署。

2. 复制的容器在其自己的Pod中运行，例如，应该有三个豆荚存在的部署扩展到三个重复
