Reverse Proxy

Installation of Caddy

Sample configuration

In this example, we use Caddy as reverse-proxy in front of Portainer. We start with a fresh Ubuntu 22.04LTS Server.

Installation of Docker and Portainier

Step 1 : Docker installation

apt install docker docker-compose

Step 2 : Portainer installation This is a summary of the commands, see the official doc for more informations.

docker pull portainer/portainer-ce
docker volue create portainer_data
docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Installation of Caddy

This is a summary of the commands, see the official doc for more informations.

Step 1 : Installation

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

Step 2 : Configuration of the proxy As portainer is running locally on port 9443, we will configure the reverse proxy to redirect port 8080 to this localport.

The configuration file /etc/caddy/Caddyfile content will be:

paxcounter.isc.heia-fr.ch:8080 {
    reverse_proxy https://localhost:9443 {
        transport http {
            tls
            tls_insecure_skip_verify
        }
    }
}

Step 3 : (re) start the Caddy proxy server
```
service caddy restart
```

Configuration of portainer

The access to the portainer is now possible through the URL https://paxcounter.isc.heia-fr.ch:8080. Follow the documentation to use this tool.
