Kubelet: surface the container creation/start failure reason
 2015-04-10 17:19:32 -07:00
Yu-Ju Hong bb417e82d7 Kubelet: surface the container creation/start failure reason 
Container creation/start failure cannot be reproduced by inspecting the
containers. This change caches such errors so that kubelet can retrieve it
later.

This change also extends FakeDockerClient to support setting error response
for a specific function.

Yifan Gu 12b382ce76 kubelet/fake_docker_client: Use self's PID instead of 42 in testing. 
This is safer to use self's PID than some arbitrary PID (say 42),
since the kubelet will set the oom_score_adj for real.

RFC: Kubelet: a step towards to better encapsulation of docker functions

Daniel Smith 6be09c5e97 Stop the bleeding for #6059 2015-04-02 13:54:10 -07:00
Yu-Ju Hong d01bc660b5 Kubelet: a step towards to better encapsulation of docker functions 
We want to stop leaking more docker details into kubelet, and we also want to
consolidate some of the existing docker interfaces/structs. This change creates
DockerManager as the new home of some functions in dockertools/docker.go. It
also absorbs containerRunner. In addition, GetDockerPodStatus is renamed to
GetPodStatus with the entire pod passed to it so that it is simialr to the what
is defined in the container Runtime interface.

Eventually, DockerManager should implement the container Runtime interface, and
integrate DockerCache with a flag to turn on/off caching. Code in kubelet.go
should not be using docker client directly.
