Kaniko reset build context in Gitlab pipeline

Question

I detected following problem with Kaniko in GitLab CI: Lets say I have this Dockerfile:

FROM nginx:latest
RUN mkdir test

Now I want to create two images from this Dockerfile. When building the second image it fails saying that the directory has been created already.

I think the reson of this has something to do with kanikos build context.

Do you have an idea how I can still build multiple images inside a single pipeline job using Kaniko?

While it might be linked to the Kaniko build context (since it does not depend on a Docker daemon and executes each command within a Dockerfile completely in userspace), a simple solution would be:

RUN mkdir -p test

That way, even if test already exist, it won't fail in error.

Its true, but it will fail at other commands such as `touch` and `git clone` – Moritz Apr 13 '23 at 11:39
