Tinytex in docker file

[hassanw65]

Hi friends, I am trying to dockerize an R shiny application which is generating a report using a Rmarkdown file. I want download a pdf report from this application. I have installed the tiny tex distribution for that purpose and my the output of tinytex:::is_tinytex() is TRUE. However when the application start to knit the file i have an error of pdflatex not found. I am sharing my docker file any help regarding it would be much appreciated.

Not a solution but you may upload your Dockerfile as a Github gist (like I did here). This way its easier to download and use. I may have time to look into your problem later this week but I can't promise.
