shinyproxy-docker-compose-example_nginx-forwarder_1 exited with code 1

When I run "docker-compose up" , nginx-forwarder exited with following messages. Please check it.

--- docker-compose messages ------

You mean you cloned the repo, run docker-compose up without any modification and you got the above error message?

Hi @shrektan I also get the same error,

app-in-compose_1 | Loading required package: shiny

@shrektan, thanks so much for putting togeather this example!

Just in case anyone else experiences similar issues, I had to do the following to get the shinyproxy service working on my computer (YMMV):

1. Download the most recent version of shinyproxy (e.g. shinyproxy-2.5.0.jar from https://www.shinyproxy.io/downloads/shinyproxy-2.5.0.jar).
2. Rename the .jar file as shinyproxy.jar
3. Move the file to shinyproxy-docker-compose-example/shinyproxy/shinyproxy.jar

Note that this didn't fix the nginx forwarder, which terminates with the following log:

nginx-forwarder_1  | 2021/08/04 00:30:59 [emerg] 7#7: no host in upstream ":3838/" in /etc/nginx/nginx.conf:21
nginx-forwarder_1  | nginx: [emerg] no host in upstream ":3838/" in /etc/nginx/nginx.conf:21
shinyproxy-docker-compose-example_nginx-forwarder_1 exited with code 1

I have the same problem too
