Kubernetes 中容器的命令行参数

Question

我正在尝试将 docker 容器部署到我的 Kubernetes 集群，但我运行遇到了将所需命令行参数传递给容器的问题。我需要传递两个参数 --provider local 和 --basedir /tmp。这是 docker 运行命令的样子（我可以运行在我的 docker 主机上没有任何问题）：

docker run -d -p 8080:8080 --name transfer-sh -v /tmp:/tmp dutchcoders/transfer.sh:latest --provider local --basedir /tmp

但是，当我将部署 YAML 应用到我的集群时，容器失败并出现此错误（我正在运行宁 kubectl apply -f deploy.yaml 将我的更改应用到集群）：

Incorrect Usage. flag provided but not defined: -provider local

所以我的 YAML 指定标志应该是 --provider，但由于某种原因我还没有找到容器只看到 -provider 这确实不是一个有效的选项。这是完整的帮助信息：

这是我要部署的映像的 Docker 中心：dutchcoders/transfer.sh

这里是GitHub：https://github.com/dutchcoders/transfer.sh

我的集群版本是 1.23.4 完整的部署 YAML 在这里：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: transfer-sh
  namespace: transfer-sh
  labels:
    app: "transfer-sh"
spec:
  replicas: 1
  selector:
    matchLabels:
      app: transfer-sh
  template:
    metadata:
      labels:
        app: transfer-sh
    spec:
      containers:
      - name: transfer-sh
        image: dutchcoders/transfer.sh:latest
        args:
        - "--provider local"
        - "--basedir /tmp"
        ports:
        - containerPort: 8080

我有意没有包含任何持久卷声明。此时我只是在测试以确保容器将运行.

最初，我认为这可能是某种转义序列问题。在尝试了各种可能逃避这两个破折号的方法之后，什么都没有真正改变。我还尝试设置包含这些参数的环境变量，但这只会导致 --profile 变成 -profile.

的相同行为

如果有人有任何想法，我可以寻求帮助。我现在有点卡住了（尽管仍在排除故障）。我很好奇是否有不同的方式来传递命令标志而不是参数（或者就 k8s 而言可能没有任何区别）。

尝试：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: transfer-sh
  namespace: transfer-sh
  labels:
    app: transfer-sh
spec:
  replicas: 1
  selector:
    matchLabels:
      app: transfer-sh
  template:
    metadata:
      labels:
        app: transfer-sh
    spec:
      containers:
      - name: transfer-sh
        image: dutchcoders/transfer.sh:latest
        args:  # <-- in this case each arg is individual
        - --provider
        - local
        - --basedir
        - /tmp
        ports:
        - containerPort: 8080


NAME          READY   UP-TO-DATE   AVAILABLE   AGE
transfer-sh   1/1     1            1           91s
