Traefik on DC/OS (DCOS_OSS-1807).

[deric]

Traefik is a HTTP reverse proxy and load balancer that supports multiple backends (Marathon, etcd, consul, ZooKeeper, ...). Current version offers simple integration with Marathon backend(s). Jira Ticket DCOS_OSS-1807.

@deric This is great. PR lgtm, but @ryadav88 PTAL

[bearnard]

Is there a way to specify something like maxDcosReleaseVersion? Not sure if this will work on 1.1x due to traefik/traefik#2115

[deric]

@joerg84 Thanks Joerg.
@bearnard Good point! Currently Traefik Marathon backend go-marathon is not fully compatible with Marathon 1.5 API gambol99/go-marathon#324. So, we would have support up to DC/OS 1.9. AFAIK there's no attribute maxDcosReleaseVersion.

There's already a PR in progress, hopefully go-marathon will be backward compatible with Marathon 1.4, otherwise we would have to require DC/OS >= 1.10. Maybe somebody from Marathon developers could verify the changes?

Meanwhile can we test backwards compatibility with earlier DC/OS releases?

[ryadav88]

@deric please add a documentation example for Traefik. You can create a PR against dcos/examples and use the template from other examples there.
This is now a requirement for adding new packages to Universe.

[deric]

@ryadav88 I've added basic documentation.
@bearnard IMHO missing support for ipAddresses feature is not a blocker right now. The upcoming Traefik 1.5.0 (a rc1 is already available) might fix that. Routing to host ports or containers ports behind NAT works fine.

Traefik web interface is now accessible via DC/OS UI, also I've lowered default CPU and memory requirements. Even cpu:0.1 and mem:100 should be enough for testing Traefik.

@deric is there a work in progress to support marathon 1.5?

[deric]

@GoelDeepak Yes, see the comments above gambol99/go-marathon#327
I'm testing Traefik against Maraton 1.5.1.2 (DC/OS 1.10.1) so far without problems, but I haven't tested VLANs yet.
