Docker-无法在Kubernetes群集上启动Webpack dev服务器

我尝试在DigitalOceanKubernetes集群的Rails应用程序中启动WebpackDev服务器。我想不出正确的命令。这个应用程序在Docker本地工作。

我总是出现这样的错误:

错误:无法启动容器“exactpos webpack”:来自的错误响应 守护进程:oci runtime create失败:container_linux.go:348:正在启动 容器进程导致“exec:\”bin/bash \“:stat bin/bash:no such 文件或目录“:未知的后退重新启动失败的容器

以下是docker-compose.yml文件中的代码:

webpack_dev_server: build: .
command: ./bin/webpack-dev-server 
ports:
- 3035:3035 
volumes:
- .:/usr/src/app
- gem_cache:/gems 
env_file:
- .env/development/web
- .env/development/database environment:
- WEBPACKER_DEV_SERVER_HOST=0.0.0.0

这是我的kubectl部署yaml文件:
