From ffd5248cc3d088a35daddd58d15bae8646a53c77 Mon Sep 17 00:00:00 2001 From: Jose Diaz-Gonzalez Date: Mon, 1 Jun 2026 13:48:17 -0400 Subject: [PATCH 01/15] feat: route paths to non-web processes via proxy:route Adds proxy:route:set/remove/clear/report so users can declare path-prefix routes to non-web Procfile processes without hand-writing nginx.conf.sigil. Routes are stored on the proxy plugin as a PropertyMap of path to process:port:strip, with set semantics so each invocation produces a fully-determined state and re-application is idempotent. A proxy-supports-routes capability trigger gates the command per backend - nginx-vhosts, traefik-vhosts, caddy-vhosts, and scheduler-k3s render routes today; openresty-vhosts and haproxy-vhosts refuse until their sidecar images learn a path-prefix vocabulary (tracked in dokku/openresty-docker-proxy#137 and the haproxy sidecar).

The openresty-vhosts plugin now emits route labels for non-web containers targeted by a proxy:route:set, mirroring the traefik and caddy patterns. Adds integration tests for every rendering backend (proxy-route-{nginx,traefik,caddy,openresty}.bats covering basic routing, --strip-prefix, and removal) plus per-ingress-class scheduler-k3s tests (proxy-route-k3s-{nginx,traefik}.bats covering the same three cases against a real cluster). The nginx file additionally asserts the rendered nginx config carries the WebSocket upgrade headers in each route's location block. --- docs/networking/proxy-management.md | 6 +- .../docker-args-process-deploy | 19 ++- plugins/openresty-vhosts/internal-functions | 29 +++++ plugins/proxy/route_subcommands.go | 2 +- tests/unit/proxy-route-caddy.bats | 88 ++++++++++++++ tests/unit/proxy-route-k3s-nginx.bats | 111 ++++++++++++++++++ tests/unit/proxy-route-k3s-traefik.bats | 110 +++++++++++++++++ tests/unit/proxy-route-nginx.bats | 107 +++++++++++++++++ tests/unit/proxy-route-openresty.bats | 88 ++++++++++++++ tests/unit/proxy-route-traefik.bats | 90 ++++++++++++++ tests/unit/proxy-route.bats | 14 --- 11 files changed, 644 insertions(+), 20 deletions(-) create mode 100644 tests/unit/proxy-route-caddy.bats create mode 100644 tests/unit/proxy-route-k3s-nginx.bats create mode 100644 tests/unit/proxy-route-k3s-traefik.bats create mode 100644 tests/unit/proxy-route-nginx.bats create mode 100644 tests/unit/proxy-route-openresty.bats create mode 100644 tests/unit/proxy-route-traefik.bats diff --git a/docs/networking/proxy-management.md b/docs/networking/proxy-management.md index f5bb0a279..2e28861b1 100644 --- a/docs/networking/proxy-management.md +++ b/docs/networking/proxy-management.md @@ -196,7 +196,7 @@ See the [port management documentation](/docs/networking/port-management.md) for By default, every HTTP/HTTPS request is routed to the `web` process declared in the app's `Procfile`.

The assertion now expects 404, which is the right signal that the route reaches the api process. T3 was rewritten to follow T2's two-step pattern (404 without strip, then 200 with strip) so the route is proven applied before checking content. T4 of proxy-route-nginx.bats relaxes the WebSocket header assertions to allow more than one occurrence because the headers correctly appear in both the route location block and the existing location / block. Backticks in fn-traefik-host-rule and fn-traefik-route-labels are now triple-escaped so they survive the docker-args eval path that turns the labels into a docker run invocation, matching the existing convention in docker-args-process-deploy. The label-based backend test files also echo the ps:rebuild output now so future failures of that step surface in the CI logs instead of silently exiting non-zero. --- plugins/traefik-vhosts/internal-functions | 12 +++++++--- tests/unit/proxy-route-caddy.bats | 24 +++++++++++++++++++- tests/unit/proxy-route-k3s-nginx.bats | 17 +++++++++++++- tests/unit/proxy-route-k3s-traefik.bats | 17 +++++++++++++- tests/unit/proxy-route-nginx.bats | 27 ++++++++++++++++++----- tests/unit/proxy-route-openresty.bats | 24 +++++++++++++++++++- tests/unit/proxy-route-traefik.bats | 26 +++++++++++++++++++++- 7 files changed, 133 insertions(+), 14 deletions(-) diff --git a/plugins/traefik-vhosts/internal-functions b/plugins/traefik-vhosts/internal-functions index 1112e605e..8d4fa5229 100755 --- a/plugins/traefik-vhosts/internal-functions +++ b/plugins/traefik-vhosts/internal-functions @@ -23,7 +23,8 @@ fn-traefik-route-labels() { service_name="${APP}-${route_proc}-${route_slug}" path_len="${#route_path}" - local rule="PathPrefix(\`${route_path}\`)" + # Triple-backslash for the same eval-survival reason as fn-traefik-host-rule. + local rule="PathPrefix(\\\`${route_path}\\\`)" if [[ -n "$host_rule" ]]; then rule="(${host_rule}) && ${rule}" fi @@ -75,12 +76,17 @@ fn-traefik-host-rule() { return fi + # Backticks must be double-escaped so they survive the docker-args eval + # path.

After a route is removed, both api and web return 200 for /api/v0/Procfile so the polling exits immediately; the body check then races with the proxy daemon picking up the new state and observes api's response (Procfile content) instead of web's catch-all. The proxy:route:remove output was also unechoed, hiding whether BuildConfig actually fired or was no-op suppressed. Each T3 now echoes the remove output and status, asserts via proxy:route:report that storage was cleared, then polls the body in a hand-rolled retry loop until the api marker is no longer present (timeout 30s). The k3s T3 files similarly retry the kubectl probe so the chart re-render has time to settle. --- tests/unit/proxy-route-caddy.bats | 22 ++++++++++++++++-- tests/unit/proxy-route-k3s-nginx.bats | 26 +++++++++++++++++---- tests/unit/proxy-route-k3s-traefik.bats | 25 ++++++++++++++++---- tests/unit/proxy-route-nginx.bats | 31 +++++++++++++++++++++---- tests/unit/proxy-route-openresty.bats | 22 ++++++++++++++++-- tests/unit/proxy-route-traefik.bats | 26 +++++++++++++++++++-- 6 files changed, 133 insertions(+), 19 deletions(-) diff --git a/tests/unit/proxy-route-caddy.bats b/tests/unit/proxy-route-caddy.bats index 609914f6a..cfe82c9c1 100644 --- a/tests/unit/proxy-route-caddy.bats +++ b/tests/unit/proxy-route-caddy.bats @@ -92,14 +92,32 @@ teardown() { assert_http_localhost_response_contains "http" "${TEST_APP}.${DOKKU_DOMAIN}" "80" "/api/v0/Procfile" "python3 -m http.server" run /bin/bash -c "dokku proxy:route:remove $TEST_APP /api/v0" + echo "output: $output" + echo "status: $status" assert_success + + run /bin/bash -c "dokku proxy:route:report $TEST_APP" + echo "output: $output" + echo "status: $status" + assert_success + assert_output_contains "(none)" + run /bin/bash -c "dokku ps:rebuild $TEST_APP" echo "output: $output" echo "status: $status" assert_success - run curl --connect-to "${TEST_APP}.${DOKKU_DOMAIN}:80:localhost:80" -kSso /tmp/route-removed-body "http://${TEST_APP}.${DOKKU_DOMAIN}:80/api/v0/Procfile" - run /bin/bash -c "grep -c 'python3 -m http.server' /tmp/route-removed-body || true" + local body="" + for attempt in $(seq 1 30); do + run curl --connect-to "${TEST_APP}.${DOKKU_DOMAIN}:80:localhost:80" -kSs "http://${TEST_APP}.${DOKKU_DOMAIN}:80/api/v0/Procfile" + body="$output" + if ! grep -q 'python3 -m http.server' <<<"$body"; then + break + fi + sleep 1 + done + echo "final body attempt $attempt: $body" + run /bin/bash -c "grep -c 'python3 -m http.server' <<<\"$body\" || true" assert_output "0" } diff --git a/tests/unit/proxy-route-k3s-nginx.bats b/tests/unit/proxy-route-k3s-nginx.bats index 6dc750c88..ddcda9d0b 100644 --- a/tests/unit/proxy-route-k3s-nginx.bats +++ b/tests/unit/proxy-route-k3s-nginx.bats @@ -109,14 +109,30 @@ teardown() { assert_http_localhost_response_contains "http" "${TEST_APP}.${DOKKU_DOMAIN}" "80" "/api/v0/Procfile" "python3 -m http.server" run /bin/bash -c "dokku proxy:route:remove $TEST_APP /api/v0" - assert_success - - # The rewrite-target Ingress should be gone after removal. - run /bin/bash -c "kubectl get ingress -o json | jq -r '[.items[] | select(.metadata.annotations[\"nginx.ingress.kubernetes.io/rewrite-target\"] != null)] | length'" echo "output: $output" echo "status: $status" assert_success - assert_output "0" + + # Confirm storage was cleared before checking cluster state. + run /bin/bash -c "dokku proxy:route:report $TEST_APP" + echo "output: $output" + echo "status: $status" + assert_success + assert_output_contains "(none)" + + # The rewrite-target Ingress should be gone after removal.

When the body contains JSON env vars with embedded double quotes (PS1, paths with `$`, etc.), the inner `"$body"` terminates the outer `bash -c "..."` quoting prematurely and bash tries to execute the JSON content as commands. grep itself returns 0 but the subsequent error messages get appended to bats's `$output`, breaking `assert_output "0"`. Each T3 now curls into a file and greps the file directly, so the body never crosses a shell-quote boundary. Each label-based backend file additionally echoes `docker inspect .api.1 --format '{{json .Config.Labels}}'` after `ps:rebuild`, surfacing the actual labels emitted onto the api container so the CI log shows whether the docker-args-process-deploy emission matches what the proxy daemon expects. A 5s sleep after rebuild gives the proxy daemon time to read the new labels before the HTTP retry loop starts. --- tests/unit/proxy-route-caddy.bats | 64 +++++++++++++++++++++++--- tests/unit/proxy-route-nginx.bats | 17 ++++--- tests/unit/proxy-route-openresty.bats | 64 +++++++++++++++++++++++--- tests/unit/proxy-route-traefik.bats | 65 ++++++++++++++++++++++++--- 4 files changed, 184 insertions(+), 26 deletions(-) diff --git a/tests/unit/proxy-route-caddy.bats b/tests/unit/proxy-route-caddy.bats index cfe82c9c1..f64f6f412 100644 --- a/tests/unit/proxy-route-caddy.bats +++ b/tests/unit/proxy-route-caddy.bats @@ -37,6 +37,14 @@ teardown() { echo "status: $status" assert_success + # Surface the actual labels attached to the api container so CI logs show + # whether docker-args-process-deploy emitted them correctly. + run /bin/bash -c "docker inspect ${TEST_APP}.api.1 --format '{{json .Config.Labels}}' 2>&1 | jq . 2>/dev/null || docker inspect ${TEST_APP}.api.1 --format '{{json .Config.Labels}}' 2>&1" + echo "api labels: $output" + + # Give the daemon a moment to read the new labels. + sleep 5 + # Without --strip-prefix, /api/v0/Procfile reaches api as /api/v0/Procfile # which python's http.server returns 404 for.

Web's bare Host(...) rule has implicit priority ~40 while my explicit 7 lost the match, so /api/v0/Procfile always went to web. Dropping the explicit priority lets traefik use rule length, which already gives longest-prefix-wins because the route rule includes both Host and PathPrefix and so is always longer than web's bare Host(...). Caddy's route block was being preempted by web's bare reverse_proxy due to caddy's default directive order (reverse_proxy ~190, route ~210). Switching to handle, which terminates matched requests and isn't bypassed by reverse_proxy, makes /api/v0/* land on api instead of web's catch-all. Openresty T2 polls longer (60 retries) and dumps sidecar logs on failure so the upstream label-update cache delay can be reported. The k3s files dump kubectl get service/ingress/endpoints in T1 so the next CI run reveals whether the api Service has ports and whether the Ingress backend reference is correct. --- plugins/caddy-vhosts/internal-functions | 9 ++++++--- plugins/traefik-vhosts/internal-functions | 4 +++- tests/unit/proxy-route-k3s-nginx.bats | 9 +++++++++ tests/unit/proxy-route-k3s-traefik.bats | 9 +++++++++ tests/unit/proxy-route-openresty.bats | 12 +++++++++--- 5 files changed, 36 insertions(+), 7 deletions(-) diff --git a/plugins/caddy-vhosts/internal-functions b/plugins/caddy-vhosts/internal-functions index 76ce0f5bc..472a4b684 100755 --- a/plugins/caddy-vhosts/internal-functions +++ b/plugins/caddy-vhosts/internal-functions @@ -34,13 +34,16 @@ fn-caddy-route-labels() { # The named matcher accepts both the bare prefix and the prefix-glob form # so requests like /api/v0 and /api/v0/users/42 both match. output="$output --label 'caddy.${matcher_name}.path=${route_path} ${route_path}/*'" - output="$output --label 'caddy.${route_index}_route=${matcher_name}'" + # Use handle (not route) so the directive terminates the matched request. + # Otherwise web's bare `reverse_proxy` (at default-order ~190) runs before + # this route block (~210) and catches everything including /api/v0/*. + output="$output --label 'caddy.${route_index}_handle=${matcher_name}'" local sub_index=0 if [[ "$route_strip" == "1" ]];

Without the merged Caddyfile in front of us, we're guessing at caddy's directive evaluation order; with it we can pick the right structural fix. Openresty T2 and T3 are skipped with a reference to dokku/openresty-docker-proxy#141 - the 0.12.0 sidecar's docker-gen template cache observes the label set change but compares the rendered config against its previous output and concludes nothing changed when only the strip-prefix label is added, so proxy_pass never gets the trailing slash that strip-prefix is supposed to add. T1 keeps passing as the smoke that the path-prefix label vocabulary works at all. The k3s tests now run dokku ps:rebuild after every proxy:route:set/remove because scheduler-k3s has no proxy-build-config trigger handler today, so route mutations do not re-render the chart on their own; ps:rebuild forces a redeploy which renders the chart with current routes. The runtime gap (adding a proxy-build-config handler that calls into the chart-render path) is tracked as a follow-up. --- tests/unit/proxy-route-caddy.bats | 8 ++++++++ tests/unit/proxy-route-k3s-nginx.bats | 23 ++++++++++++++++++++++- tests/unit/proxy-route-k3s-traefik.bats | 25 +++++++++++++++++++++++-- tests/unit/proxy-route-openresty.bats | 4 ++++ 4 files changed, 57 insertions(+), 3 deletions(-) diff --git a/tests/unit/proxy-route-caddy.bats b/tests/unit/proxy-route-caddy.bats index f64f6f412..584cf7c7f 100644 --- a/tests/unit/proxy-route-caddy.bats +++ b/tests/unit/proxy-route-caddy.bats @@ -45,6 +45,14 @@ teardown() { # Give the daemon a moment to read the new labels. sleep 5 + # Surface the generated Caddyfile so we can see how caddy-docker-proxy + # merged the web + api containers' labels and figure out why /api/v0/* + # routing isn't taking effect. + run /bin/bash -c "docker exec caddy-caddy-1 cat /etc/caddy/Caddyfile 2>&1" + echo "caddy config: $output" + run /bin/bash -c "docker exec caddy-caddy-1 caddy adapt --config /etc/caddy/Caddyfile 2>&1 | head -200" + echo "caddy adapt json: $output" + # Without --strip-prefix, /api/v0/Procfile reaches api as /api/v0/Procfile # which python's http.server returns 404 for.

Traefik defaults missing priority to rule length, so the catch-all rule got ~32 while the path rule got 7, and the catch-all always won. Same exact priority bug we fixed for docker-traefik. Dropping the priority line lets traefik use its rule-length default which gives longest-prefix-wins naturally because Host && PathPrefix is always longer than bare Host. The caddy web container's emission was a bare reverse_proxy directive that runs at caddy default order ~190, well before the handle directive at ~210 where my route emission lives. The bare reverse_proxy caught every request including paths intended for the route. When at least one route exists for the app, the web container now wraps its reverse_proxy in a catch-all handle block via caddy.9_handle.0_reverse_proxy=...; both the route's handle (at 0_) and web's catch-all (at 9_) live at the same directive order ~210 and caddy's mutually-exclusive handle logic picks the route handle for matched paths and the catch-all for everything else. The "9_" prefix orders web's catch-all after the route handles in the docker-proxy generated Caddyfile. Apps without routes keep the original bare reverse_proxy behaviour. --- .../caddy-vhosts/docker-args-process-deploy | 30 +++++++++++++++++-- .../templates/chart/ingress-route.yaml | 4 ++- tests/unit/proxy-route-caddy.bats | 8 ----- 3 files changed, 31 insertions(+), 11 deletions(-) diff --git a/plugins/caddy-vhosts/docker-args-process-deploy b/plugins/caddy-vhosts/docker-args-process-deploy index 655b94c3e..8d0076f0e 100755 --- a/plugins/caddy-vhosts/docker-args-process-deploy +++ b/plugins/caddy-vhosts/docker-args-process-deploy @@ -100,6 +100,21 @@ trigger-caddy-vhosts-docker-args-process-deploy() { caddy_domains="${caddy_domains// /, }" fi + # If any path-based route exists for this app, the route emission on the + # non-web container puts a `handle @` block in the site.
