Multiple containers per domain possible?

[OmgImAlexis]

How would I setup multiple containers making up a single domain?

For example all containers would use example.com but with different paths /, /admin, /dashboard for each. Currently if I add multiple containers with the same domain the generator just creates multiple entries for the domain.

You can add paths to address label. Caddy accepts with multiple config entries for same domain.

Just use:
caddy.address=example.com
caddy.address=example.com/admin
caddy.address=example.com/dashboard

Test:

docker service create --network caddy -l caddy.address=whoami.caddy-proxy -l caddy.targetport=8000 -l caddy.tls=off --name whoami0 jwilder/whoami
docker service create --network caddy -l caddy.address=whoami.caddy-proxy/path1 -l caddy.targetport=8000 -l caddy.tls=off --name whoami1 jwilder/whoami
docker service create --network caddy -l caddy.address=whoami.caddy-proxy/path2 -l caddy.targetport=8000 -l caddy.tls=off --name whoami2 jwilder/whoami

curl -H Host:whoami.caddy-proxy http://localhost:2015
curl -H Host:whoami.caddy-proxy http://localhost:2015/path1
curl -H Host:whoami.caddy-proxy http://localhost:2015/path2

So more or less the caddy.targetpath isn't needed then? I know this is a work in progress but the readme is a tad confusing.

[lucaslorentz]

Actually it is still needed. because it is the path the proxy target will receive the requests.

You can combine both to achieve different results.

Redirects whole domain to whole container

address=whoami.caddy-proxy

Redirects whole domain to container path

address=whoami.caddy-proxy
targetpath=/my-path

Redirects domain path to whole container

address=whoami.caddy-proxy/path1

Redirects domain path to container path

address=whoami.caddy-proxy/path1
targetpath=/path1
