How to set the workdir of a container launched by Kubernetes

Question

Is it possible to set the working directory when launching a container with Kubernetes ?

Answer 1

Yes, through the workingDir field of the container spec. Here's an example replication controller with an nginx container that has workingDir set to /workdir:

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

It should be also possible to set the working directory using env and command attributes. Below is an example:

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)"]
