Here's what my Dockerfile looks like for an image I'm creating.
FROM python:3.7-alpine
COPY requirements.txt /
RUN pip install -r /requirements.txt
ENV U_PATH="a"
WORKDIR $U_PATH
I override the env variable U_PATH when I call it using docker run -it -e U_PATH=/mnt temp:v1 /bin/sh but the WORKDIR is set during build time and I cannot change that during runtime.
Is there any way to dynamically set the working directory at runtime by passing an env variable?
While not an environment variable, don't forget you can alter the working directory of a Pod's container via the workingDir: PodSpec field
containers:
- name: foo
image: 'temp:v1'
workingDir: /mnt
