`tail -f` experience for Kubernetes Pods

As you know, `kubectl logs` can stream only ONE pod at the same time. `k8stail` enables you to watch __log streams of ALL pods__ in the specified namespace or labels in real time, like `tail -f`.

## Requirements

Kubernetes 1.3 or above

## Installation

### Using Homebrew (OS X only)

Formula is available at [dtan4/homebrew-dtan4](https://github.com/dtan4/homebrew-dtan4).

```bash
$ brew tap dtan4/dtan4
$ brew install k8stail
```

### Precompiled binary

Precompiled binaries for Windows, OS X, Linux are available at [Releases](https://github.com/dtan4/k8stail/releases).

### From source

```bash
$ go get -d github.com/dtan4/k8stail
$ cd $GOPATH/src/github.com/dtan4/k8stail
$ make deps
$ make install
```

### Run in a Docker container

Docker image is no longer provided officially.
If you'd like to run k8sec in Docker image, see [`Dockerfile`](Dockerfile) and build image by yourself.

```bash
docker build -t k8stail .
```

## Usage

Logs of all pods, all containers in pod in the specified namespace are streaming. When new pod is added, logs of the pod also appears.
To stop streaming and exit, press `Ctrl-C`.

```bash
$ k8stail --namespace awesome-app
Namespace: awesome-app
Labels:
----------
Pod awesome-app-web-4212725599-67vd4 has detected

With `--labels` option, you can filter pods to watch.

```bash
$ k8stail --namespace awesome-app --labels name=awesome-app-web
Namespace: awesome-app
Labels:    name=awesome-app-web

```

### kubeconfig file

`k8stail` uses `~/.kube/config` as default. You can specify another path by `KUBECONFIG` environment variable or `--kubeconfig` option. `--kubeconfig` option always overrides `KUBECONFIG` environment variable.

```bash
$ KUBECONFIG=/path/to/kubeconfig k8stail
# or
$ k8stail --kubeconfig=/path/to/kubeconfig
```

### Options

|Option|Description|Required|Default|
|---------|-----------|-------|-------|
|`--context=CONTEXT`|Kubernetes context|||
|`--debug`|Debug mode using pprof (http://localhost:6060)||`false`|
|`--kubeconfig=KUBECONFIG`|Path of kubeconfig||`~/.kube/config`|
|`--labels=LABELS`|Label filter query (e.g. `app=APP,role=ROLE`)|||
|`--namespace=NAMESPACE`|Kubernetes namespace||`default`|
|`--timestamps`|Include timestamps on each line||`false`|
|`-h`, `-help`|Print command line usage|||
|`-v`, `-version`|Print version|||

## Development
