* alpine: dl-4.alpinelinux.org is dead, use another server
* increase buffer for docker stats
Attempt to avoid the following message:
docker container: dropping stats.
* probe: better timeout error messages
The logs contains the following messages:
Process reporter took longer than 1s
K8s reporter took longer than 1s
Docker reporter took longer than 1s
Endpoint reporter took longer than 1s
This patch prints how long it takes.
* Remove individually vendored k8s.io/kubernetes/pkg/<foo>
* Vendor the whole of vendor/k8s.io/kubernetes/pkg
* Add k8s pod log control
* Tag pods with host id and include them in the host topology as children.
* adding a basic test for kubernetes.Reporter.GetLogs
* Bump github.com/ugorji/go/codec, to get fixes which make
github.com/2opremio/go-1/codec unnecessary
* Remove github.com/2opremio/go-1/codec
* Remove type embeddings to avoid the problem explained at
https://github.com/ugorji/go/issues/141#issuecomment-185450157
This caused a dependency chain reaction (sigh):
* All the k8s packages had to be fetched again. This in turn required:
* Pining github.com/docker/docker/pkg/parsers to
0f5c9d301b9b1cca66b3ea0f9dec3b5317d3686d to cirvumvent
https://github.com/kubernetes/kubernetes/issues/18774
* Update github.com/juju/ratelimit
* Make probe/kubernetes/client.go comply with API changes.
* New encoding format:
* Msgpack reports between probe<->app (smaller representation, faster to
encode/decode).
* Still use JSON between app<->UI (try to avoid making javascript deal with
mspack).
The app still suports publishing reports in both gob and JSON, not braking
backwards compatibility.
* Use compile-time generated marshallers/unmarshallers for higher performance. In
order to be able to skip code-generation for certain types, I included
https://github.com/2opremio/go-1/tree/master/codec/codecgen instead of
upstream until https://github.com/ugorji/go/pull/139 is merged.
* Encode/decode intermediate types using github.com/ugorji/go/codec.Selfer
for higher performance and reducing garbage collection (no temporary buffers).
- Run the Weave integrations regardless of if weave is detected.
- Make everything backoff and not spam the logs.
- Add miekg dns to vendor.
- Have the app periodically register with weaveDNS, and the probe do lookups there.
- Decide what the local networks are at runtime, not once at startup.
- Correctly resolve app ids, fixes#825
- Restructure main funcs for clean defer-stack-unwinds
- Fix Docker container to handle signals properly
- Introduce runsvinit for container init process
- Integration test
