If you need access to the `secrets` file from a non-root user, you'll need to set the `uid` in the `--mount` argument:

```Dockerfile
#syntax=docker/dockerfile:1.2

FROM alpine

# Create non-root user
RUN addgroup -S newuser && adduser -u 1001 -S -g newuser newuser

# Run everything after as non-privileged user.
USER newuser

RUN --mount=type=secret,uid=1001,id=github_token \
