- Improves default filtering behavior to filter by container health/healthState
- Optionally allows filtering by service health/healthState
- Allows configuration of refresh interval
For the two existing health check parameters (path and interval), we add
support for Marathon labels.
Changes in detail:
- Extend the Marathon provider and template.
- Refactor Server.loadConfig to reduce duplication.
- Refactor the healthcheck package slightly to accommodate the changes
and allow extending by future parameters.
- Update documentation.
The IP-Per-Task feature changed the behavior for
clients without this configuration (using the task IP instead
of task hostname). This patch make the new behavior available
just for Mesos installation with IP-Per-Task enabled. It also
make it possible to force the use of task's hostname.
Previously, we did the check too late resulting in the traefik.port
label not being effective.
The change comes with additional refactorings in production and tests.
This fix allows the Traefik Rancher provider to obtain a complete view
of the environments, services and containers being managed by the
Rancher deployment.
- Split the file into smaller ones (docker, swarm and service tests)
- Use some builder to reduce a little bit the noise for creating containers

* Abort Kubernetes Ingress update if Kubernetes API call fails
Currently if a Kubernetes API call fails we potentially remove a working service from Traefik. This changes it so if a Kubernetes API call fails we abort out of the ingress update and use the current working config. Github issue: #1240
Also added a test to cover when requested resources (services and endpoints) that the user has specified don’t exist.
* Specifically capturing the tc range as documented here: https://blog.golang.org/subtests
* Updating service names in the mock data to be more clear
* Updated expected data to match what currently happens in the loadIngress
* Adding a blank Servers to the expected output so we compare against that instead of nil.
* Replacing the JSON test output with spew for the TestMissingResources test to help ensure we have useful output incase of failures
* Adding a temporary fix to the GetEndoints mocked function so we can override the return value for if the endpoints exist.
After the 1.2 release the use of properExists should be removed and the GetEndpoints function should return false for the second value indicating the endpoint doesn’t exist. However at this time that would break a lot of the tests.
* Adding quick TODO line about removing the properExists property
* Link to issue 1307 re: properExists flag.
If the ECS cluster has > 100 tasks, passing them to
ecs.DescribeTasksRequest() will result in the AWS API returning
errors.
This patch breaks them into chunks of at most 100, and calls
DescribeTasks for each chunk.
We also return early in case ListTasks returns no values; this
prevents DescribeTasks from throwing HTTP errors.
Currently with a kv tree like:
/traefik/backends/b1/servers/ẁeb1
/traefik/backends/b1/servers/web2
/traefik/backends/b1/servers/web2/url
Traefik would try to forward traffic to web1, which is impossible as
traefik doesn't know the url of web1.
This commit solve that, by ignoring backend server with no url "key"
when generating the config.
This is very useful, for people who use etcd TTL feature. They can then
just "renew" the url key every X second, and if the server goes down, it
is automatic removed from traefik after the TTL.

- traefik.mycustomservice.frontend.rule=Path:/mycustomservice
- traefik.anothercustomservice.port=8080
- traefik.anothercustomservice.frontend.rule=Path:/anotherservice
all traffic to frontend /mycustomservice is redirected to the port 443 of the container while using /anotherservice will redirect to the port 8080 of the docker container

Detect whether in-cluster or cluster-external Kubernetes client should
be used based on the KUBERNETES_SERVICE_{HOST,PORT} environment
variables.
Adds bearer token and CA certificate file path parameters.
In Swarm mode with with Docker Swarm’s Load Balancer disabled (traefik.backend.loadbalancer.swarm=false)
service name will be the name of the docker service and name will be the container task name
(e.g. whoami0.1). When generating backend and fronted rules, we will use service name instead of name if a
rule is not provided.
Initialize dockerData.ServiceName to dockerData.Name to support non-swarm mode.
SWARM Mode has it's own built in Load balancer, so if we want to leverage sticky sessions,
or if we would just prefer to bypass it and go directly to the containers (aka tasks), via
--label traefik.backend.disable.swarm.loadbalancer=true
then we need to let Traefik know about the underlying tasks and register them as
services within it's backend.
The IP-Per-Task PR introduced a bug using the marathon application
port mapping. This port should be used only in the proxy server, the
downstream connection should be always made with the task port.
This commit fix the regression and adds a unit test to prevent new
problems in this setup.
Only use one channel for all watches
Re-use stop channel from the provider
Skip events that have already been handled by the provider, builds on 007f8cc48ea9504bb7754c5e3244124be422f47d
On a reasonably sized cluster:
63 nodes
87 services
90 endpoints
The initialization of the k8s provider would hang.
I tracked this down to the ResourceEventHandlerFuncs. Once you reach the
channel buffer size (10) the k8s Informer gets stuck. You can't read or
write messages to the channel anymore. I think this is probably a lock
issue somewhere in k8s but the more reasonable solution for the traefik
usecase is to just drop events when the queue is full since we only use
the events for signalling, not their content, thus dropping an event
doesn't matter.
