1. Caddy version (caddy version
): Caddy V2.1.1
2. How I run Caddy:
I am running cadddy from a Docker container, this is my build file:
'FROM caddy/caddy:2.1.1-alpine
ENV CONFIG_DIR /etc/caddy
ENV DATA_DIR /usr/share/caddy
COPY Caddyfile $CONFIG_DIR/Caddyfile
COPY index.html /usr/share/caddy/index.html'
and this is the command I am using to run it:
docker run -d --name="caddy" -p 2019:2019 -p 2015:2015 caddy:1.0
a. System environment:
I am running on Windows 10, Docker Desktiop 2.3.0.4
b. Command:
Caddy gets started automatically with the launch fof the docker container
c. Service/unit/compose file:
See above.
d. My complete Caddyfile or JSON config:
:2015 {
reverse_proxy localhost:8080
}
3. The problem I’m having:
I am all new to Caddy and I was simply tryin gthe most basic revese proxey setup following the Documentation given on the Caddy Site and on the Github repo site:
The backend app that I am reverse-proxying to is running on localhost:8080. It is a payara webap server with a J2EE app in a context called dashboard.
The standalone URL for the app is http://localhost:8080/dashboard/login.xhtml
When I now try to reach his URL through Caddy, I point my browser to http://localhost:2015/dashboard/index.html assuming that the redirect from Caddy will resolve this to the roper (standalone, see above) URL.
It is not happening, instead I get the following Error.
4. Error messages and/or full log output:
{“level”:“error”,“ts”:1606145180.5917492,“logger”:“http.log.error”,“msg”:“dial tcp 127.0.0.1:8080: connect: connection refused”,“request”:{“method”:“GET”,“uri”:"/dashboard/login.xhtml",“proto”:“HTTP/1.1”,“remote_addr”:“172.17.0.1:57374”,“host”:“localhost:2015”,“headers”:{“Cache-Control”:[“max-age=0”],“User-Agent”:[“Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.66 Safari/537.36”],“Accept”:[“text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9”],“Sec-Fetch-Site”:[“none”],“Sec-Fetch-User”:["?1"],“Cookie”:[“JSESSIONID=55a3bb1e303291b68d1025bcbc78; JSESSIONID=583ef41f3383351a4a14dacd7ac1”],“Connection”:[“keep-alive”],“Upgrade-Insecure-Requests”:[“1”],“Sec-Fetch-Mode”:[“navigate”],“Sec-Fetch-Dest”:[“document”],“Accept-Encoding”:[“gzip, deflate, br”],“Accept-Language”:[“de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7”]}},“duration”:0.0003584,“status”:502,“err_id”:“a2wcuz85x”,“err_trace”:“reverseproxy.(*Handler).ServeHTTP (reverseproxy.go:411)”}
5. What I already tried:
- I made sure that the backend service is up and running.
- I tried to put the Caddy container and the Payara Web App in two different containers into a docker-compose setup (this is closed to what I want to deploy ultimately). There, I am getting the exact same error message like above.
