[NTG-context] curl missing from Docker image -> install-modules does not work

[NTG-context] curl missing from Docker image -> install-modules does not work

[Marco Riggirello]

[-- Attachment #1.1: Type: text/plain, Size: 5543 bytes --]

Hello,

installing modules into the docker image is not possible since the curl 
command is not part of the image. If I run

    $ docker run --rm --entrypoint "" contextgarden/context:lmtx /bin/sh
    -c "cd /context/tex/ && mtxrun --script install-module --install filter"

I get (see line 4)

mtx-install-modules |
mtx-install-modules | installed: filter

This affects also installations outside docker if the user has a system 
without curl the mtxrun script end without throwing a very evident error.

I hope it helps. Thanks to all the contributors for the their work.

Best regards

Hi Marco,

I don't know who produces the contextgarden/context:lmtx build (presumably it's now part of the build farm?) but according to <https://hub.docker.com/r/contextgarden/context> it is supposed to have all modules already installed.

However, running 

 $ docker run --rm --entrypoint "" contextgarden/context:lmtx /bin/sh -c "cd /context/tex && mtxrun --script install-modules --installed"

suggests that there aren't any installed. So maybe Hans could prod whoever supports the build farm to look into it?

In the meantime, if you build your own container image using the Dockerfile on the Wiki <https://wiki.contextgarden.net/Installing_ConTeXt_LMTX_into_a_Docker_container> it is easy to include 'curl' - just add it after 'unzip' - however that doesn't seem to fix your problem since:

$ docker build -t context .
$ docker run --rm --entrypoint "" context /bin/sh -c "cd /opt/context/tex/ && mtxrun --script install-module --install filter"

appears to do something and there is no obvious error message in the visible output, but

$ docker run --rm --entrypoint "" context /bin/sh -c "cd /opt/context/tex && mtxrun --script install-modules --installed"

shows that the filter module still wasn't installed.

Sorry I can't help you any further right now - I'm not familiar enough with the install script to be able to quickly zero in on the problem

Regards,

[Marco Riggirello]

Hi Bruce,

thanks for your suggestions. Since I wanted to play with a solution 
similar to the one posted by Adityam on his blog

https://adityam.github.io/context-blog/post/markdown-with-gpp/

I ended up with a custom Docker image to have gpp, pandoc and context in 
the same environment. Here's the Dockerfile, if one wants to try it out 
(or to improve it!)

In the spirit of the context world, I think a good name for this image 
could be context-gppd ;)

If it is okay with you, I can add this to the blog post (and credit that it is from you)
