v1.13.5

Features

• A health check editor for services. A plain load balancer now has a Health check section covering every field Traefik takes: path, interval, timeout, interval when down, method, expected status, scheme, port, host header, mode and headers. All are optional, and with no path Traefik probes the server root. A pool of two or more servers without one is flagged on its card, since Traefik reports every server as up until a health check exists (#165)
• Ping checks every server in a pool. The heartbeat button asked the proxy, which answers even when one backend is dead. Each server is now checked directly, so a dead member reads as degraded and names the address, matching what the background check already reported (#165)

Fixes

• Service names were refused that Traefik accepts. The editor allowed only letters, numbers, dots, dashes and underscores, so a name like xxx (yyy) could not be opened or saved even though Traefik runs it happily. Names now allow anything Traefik does, under one rule shared by routes, services and middlewares: no @ / , : { }, nothing longer than 100 characters (#165)
• Route and middleware names were never validated at all, so a name containing @ or / could be saved and then not be addressable afterwards. They follow the same rule now
• Degraded routes were coloured but never counted. The HTTP routers card, the verdict line and the entry point rows all counted a route with a dead backend server as healthy, and a pod header read 1 down while hiding a degraded route next to it. Every one of them counts degraded now, and the count filters the Routes tab to it (#165)
• A route save truncated health check settings the route form has no editor for. Saving a route rewrote its service's health check from three fields, dropping method, port, headers and the rest. Those survive now
• A recovered pool still counted as degraded on the stat cards until the page was reloaded
• Compound durations like 1m30s were silently discarded where Traefik accepts them
• GET /api/routes/health and POST /api/settings/route-health were missing from the OpenAPI spec
