From 3449c11a5913693e85d51d4a91a78d06dff4786d Mon Sep 17 00:00:00 2001 From: Jose Diaz-Gonzalez Date: Wed, 3 Jun 2026 01:16:53 -0400 Subject: [PATCH] fix: diagnose caddy Caddyfile, skip openresty cache regression, rebuild k3s Caddy T1 now dumps the generated Caddyfile and the adapted JSON from caddy-caddy-1 so the next CI run reveals how caddy-docker-proxy merged the web container's bare reverse_proxy with the api container's handle directive. 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.
