To fix it, the documentation must be updated with:

ocker run -u "$(id -u):$(id -g)" -v $PWD:/app --tty --interactive --workdir /app ghcr.io/getzola/zola:v0.16.0 init

Thanks for posting this.

I've added the additional flags here in your fix, but I'm still receiving the error. Additionally, the stack backtrace isn't displaying any information, just <unknown> for most entries.

Here's my Dockerfile:

FROM ghcr.io/getzola/zola:v0.17.2 as zola

ENV RUST_BACKTRACE=full

VOLUME ["/app"]

WORKDIR /app

Zola v0.17.2

EDIT: I was able to fix this with the following.

podman run -it --rm -v $PWD:/app --security-opt label=disable --tty --interactive --workdir /app myzola build

Firstly, the -u "$(id -u):$(id -g)" flag can cause issues with a container that writes outside of itself and can screw up the UID, so I've omitted this flag.

My issue was actually caused by SELinux, so I disabled it with this --security-opt label=disable.

I also tested the container without the additional flags --tty and --interactive and was able to successfully run a zola build and zola serve without them.

[cskwrd]

Here is the command I was able to successfully use to run on a Windows host:

docker run -it --rm -v "$(pwd):/app" --workdir /app -p 8080:8080 ghcr.io/getzola/zola:v0.17.2 serve --interface 0.0.0.0 --port 8080 --base-url localhost

The -it flag is optional. --rm (also optional), instructs docker to clean up after the command ends.

I wasn't able to get live updates working. I think it might be due to the way docker runs on Windows (via WSL).
