How to use Quarto with python:3.13.3-alpine image

[girirajguptagithub]

Description

Hello Team,

Trying to build a docker image with python:3.13.3-alpine and quarto 1.7.31 (https://github.com/quarto-dev/quarto-cli/releases/download/v1.7.31/quarto-1.7.31-linux-amd64.tar.gz)

The build is successful but seeing the following error at runtime

/usr/local/bin/quarto: line 196: /opt/quarto-1.7.31/bin/tools/x86_64/deno: cannot execute: required file not found"

Based on the searches it seems the deno requires glibc libraries and they do not come with alpine.
The Python debian image has critical vulnerabilities and hence trying to use an alpine image.

Tried to install glibc on alpine but it failed with the following error-

ERROR: glibc-2.35-r0: trying to overwrite etc/nsswitch.conf owned by alpine-baselayout-data-3.7.0-r0

Is there a workaround to build an image?

Regards,

Unfortunately, there is no way to help you with only error messages which does not seem related to Quarto CLI at least the second one.
Unless you provide more information on how you are building your Docker image, we can't help you.

Why not use the deb file?

FWIW, the Deno alpine Dockerfile: https://github.com/denoland/deno_docker/blob/main/alpine.dockerfile

Deno binary is taken from: https://dl.deno.land/release/v${DENO_VERSION}/deno-$(echo $TARGETARCH | sed -e 's/arm64/aarch64/' -e 's/amd64/x86_64/')-unknown-linux-gnu.zip

The "trick" seems to be:

• https://github.com/denoland/deno_docker/blob/d09c10834d84e10d420ee4e21162f1453f5394bf/alpine.dockerfile#L17-L23

Thanks for the look into it!

Figured it out (in parallel to my work^^):

FYI, Quarto 1.8.11 (pre-release) uses esbuild 0.25.3.
Anyhow, the CVE reported for esbuild (golang) are false positives in the context of Quarto.

Note that removing esbuild as you do is very likely to break Quarto CLI and lead to unexpected issues.

Thanks a lot for the solution.
One doubt about the following step

COPY --from=cc --chown=root:root --chmod=755 /lib/ld-linux-* /lib/

Isn't the source and the destination folder the same? Just changing the permissions here?
I am not sure but I get the following error

COPY failed: no source files were specified

[mcanouil]

No the source is from the "cc" which is an alias to another image.
As showed, I was able to build and execute the Dockerfile.
If you have issue with it you need to figure that yourself and learn more about Docker as it's really not about Quarto CLI.

@mcanouil and @cderv thanks for your help. the above approach worked with minor changes for the copy of the libs
