# k8s-dump
Dump objects from a running Kubernetes cluster
**Build:** run `go build`
**Options:**
```
./dump --help
--alsologtostderr log to standard error as well as files
--apiserver-host string The address of the Kubernetes Apiserver to connect to in the format of protocol://address:port, e.g., http://localhost:8080. If not specified, the assumption is that the binary runs inside a Kubernetes cluster and local discovery is attempted.
--kubeconfig string Path to kubeconfig file with authorization and master location information.
--log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log_dir string If non-empty, write log files in this directory
--logtostderr log to standard error instead of files
--namespace string Only dump the contents of a particular namespace.
--output string Directory where the dump files should be created.
--skip-types stringSlice Types to skip in the dump. (default [serviceaccount])
--stderrthreshold severity logs at or above this threshold go to stderr (default 2)
-v, --v Level log level for V logs
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
```
In a terminal open a proxy connection to the cluster using kubectl:
```
kubectl proxy --port=8080
Starting to serve on 127.0.0.1:8080
```
**Running the command:**
```
./dump \
--output=$PWD/out \
--apiserver-host=http://127.0.0.1:8080
```
will dump all the object types (excluding service accounts) in the directory `--output` creating one file per namespace.
Each
```
./dump --output=/Users/aledbf/go/src/k8s.io/dump/out --apiserver-host=http://127.0.0.1:8080
