如何设置Kubernetes启动的容器的workdir

Question

使用Kubernetes启动容器时，是否可以设置工作目录？

Answer 1

可以，通过container spec的workingDir字段。下面是一个复制控制器示例，其中包含一个将workingDir设置为/workdir的nginx容器

apiVersion: v1
kind: ReplicationController
metadata:
  name: nginx
spec:
  replicas: 1
  template:
    metadata:
      labels:
        name: nginx
    spec:
      containers:
        - name: nginx
          image: mynginximage
          workingDir: /workdir

Answer 2

还可以使用env和command属性设置工作目录。下面是一个示例：

​

apiVersion: v1
kind: Pod
metadata:
  name: print-greeting
spec:
  containers:
  - name: env-print-demo
    image: bash
    env:
    - name: GREETING
      value: "Warm greetings to"
    - name: HONORIFIC
      value: "The Most Honorable"
    - name: NAME
      value: "Kubernetes"
    command: ["echo"]
    args: ["$(GREETING) $(HONORIFIC) $(NAME)"]
