can't add favicon when shinyproxy is in container

[kuzmenkov111]

Hello!

I can't add favicon.png when ShinyProxy is running as docker container.

Dockerfile:
`FROM openjdk:8-jre

RUN mkdir -p /opt/shinyproxy/
RUN wget https://www.shinyproxy.io/downloads/shinyproxy-2.3.0.jar -O /opt/shinyproxy/shinyproxy.jar
COPY application.yml /opt/shinyproxy/application.yml

RUN mkdir /opt/shinyproxy/templates
ADD templates /opt/shinyproxy/templates
ADD favicon.png /opt/shinyproxy/favicon.png

WORKDIR /opt/shinyproxy/
CMD ["java", "-jar", "/opt/shinyproxy/shinyproxy.jar"]`

And application yml:
`spring:
servlet:
multipart:
max-file-size: 300MB
max-request-size: 300MB
proxy:
title: Myapp
template-path: ./templates/1col

Maybe something is wrong with configuration files?

Hi,

Can you try favicon-path: favicon.png? I glanced at one of our config files which used a similar Dockerfile.

Depending on your setup, you can run your applications with app_direct/ (no iframe) instead of app/ (iframe) and then add the favicon to the Shiny application's head section. Of course, the login page of ShinyProxy would still have a favicon that needs to be customised then.

Best regards,

Michael

Many thanks!!!
It is solved.

1. when I use app_direct/my_app for direct access to shiny app without iframe I should add tags$head(tags$link(rel = "icon", type = "image/png", href = "favicon.png")) to shiny app. It's work!
2. when I use custom login template, I should add <link rel="shortcut icon" href="/assets/img/favicon.png" type="image/png"> to login.html file.

FYI
There is some info about login page modification
