Trying to install wallabag docker image

I’ve been struggling for several days to install a Wallabag docker image on my Hestia CP server.

I followed the instructions in the Docker documentation, to create a docker-compose.yml file and at SYMFONY__ENV__DOMAIN_NAME I put: https://wb.mycloud.com

But I’m stuck at the reverse proxy configuration stage.

I went to /usr/local/hestia/data/templates/web/nginx/, copied the existing template and modified it.

But I don’t know how I can modify the template, what I should keep and what I can change. Every time I try to enter the new modified template in the HestiaCP Edit Web Domain > Proxy template interface, I get a nginx error.

The tutorial gives the template as :

server {
listen 443;
server_name wallabag.foo.bar;

ssl on;
ssl_certificate /etc/letsencrypt/live/wallabag.foo.bar/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/wallabag.foo.bar/privkey.pem;

location / {
proxy_pass http://wallabag;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-For $remote_addr;
}

}

Could you help me make wallabag accessible from https://wb.mycloud.com? Thanks for your help.
