Is there a way to erase docker history?

When building an image I have to pass in credentials to get through a corporate proxy through a build-arg. These credentials are then visible through the docker history command. Is it possible to erase or redact my credentials from the build history?

First use the docker export command to prevent sensitive data from being shown with the history command. You need to start a container from an image first. Then we can export and import the container in one line:

docker export <CONTAINER ID> | docker import - some-image-name:latest

Then you can use some common Linux tricks to shrink Docker images. One simple trick is to clear the cache of the package manager:

# clean apt cache
apt-get clean

For details, this blog post seems to support the idea.

Using a multi-stage build, you can copy the build artifacts from the first stage into a new second stage. The second stage won't have the history of the first stage.
