proxy subdomains in docker

[ghost]

Hi,

Great project!. Apologies if this has been documented / answered before.

I am trying to set up subdomain proxy using the docker image codercom/code-server but can't seem to get it to work.
For example 5000.mydomain.com loads code server instead of the webapp.

in the usage docs it says to use this startup flag: --proxy-domain
However I can't find where to put it in docker?

It may also be relevant to say I am using jwilder/nginx-proxy image for this.

Thanks

For example 5000.mydomain.com loads code server instead of the webapp.

Can you elaborate here? I thought that's what you wanted? Also can you post your Dockerfile?

I wonder if you need to adjust your nginx config. I'm not super familiar but I'm sure we can help you

Hi thanks for the response. Code server is hosted on mydomain.com. I was reading in usage of this - https://coder.com/docs/code-server/latest/guide#proxying-to-create-a-react-app

So my intent was for 3000.mydomain.com in this case to load the development server of create-react-app (like /proxy/3000 does) instead it loads code server.

My Dockerfile? im using this image https://hub.docker.com/r/codercom/code-server

to build (roughly):

docker run -d
--name=coder
--restart=unless-stopped
-e PGID=1000 -e PUID=1000
-e password=password
-e VIRTUAL_HOST=mydomain.com,3000.mydomain.com,5000.mydomain.com
-e VIRTUAL_PORT=8080
-e LETSENCRYPT_HOST=mydomain.com,3000.mydomain.com,5000.mydomain.com
-e LETSENCRYPT_EMAIL=email
-v "/home/user/workspaces:/home/coder/project"
-v "/mnt:/mnt"
-v "/opt:/host_opt"
-v "/home/user:/home/coder/host"
--restart=unless-stopped
codercom/code-server:latest

Sorry if this doesn't clear up the questions

Figured it out. Went into the config.yml and added proxy-domain: mydomain.com rather than using a flag and now works as expected.

Ah-ha! Nice!
