checontroller

Simple utility being built to do some common Eclipse che tasks such as

• ✓ refresh che pods to make it OpenShift compatible, this what currently replace_stacks does

• [] install che on to OpenShift via cli, the idea of this to build CLI installer for Eclipse that can connect to OpenShift cluster and depoloy che

• [] undeploy or cleanup, just rollback of install

Warning

This application is still under development and features might change

Pre-Requsite

• golang is installed locally

• Che is deployed and running in OpenShift

Build

go get  github.com/kameshsampath/checontroller
cd $GOPATH/src/github.com/kameshsampath/checontroller
make build (1)

1. build che controller for your platform

Usage

Options

The available options can be seen via checontroller -h

  -alsologtostderr
        log to standard error as well as files
  -cheEndpointURI string
        The Che EndpointURI usually its computed assuming the deployment name `che`, with namespace being derived form the pod
        e.g if namespace is `myproject` and deployment name is `che` - then the che endpoint will be "http://che-myproject.openshiftip.nip.io"
  -incluster
        Whether the application is deployed inside Kubernetes cluster or outside
  -kubeconfig string
        (optional) absolute path to the kubeconfig file (default "/Users/kameshs/.kube/config")
  -log_backtrace_at value
        when logging hits line file:N, emit a stack trace
  -log_dir string
        If non-empty, write log files in this directory
  -logtostderr
        log to standard error instead of files
  -namespace string
        The Kubernetes Namespace to use
  -newStackURL string
        The New Stacks URL (default "https://raw.githubusercontent.com/redhat-developer/rh-che/master/assembly/fabric8-stacks/src/main/resources/stacks.json")
  -stderrthreshold value
        logs at or above this threshold go to stderr
  -v value
        log level for V logs
  -vmodule value
        comma-separated list of pattern=N settings for file-filtered logging

Out of OpenShift Cluster

Usually it can be run out of openshift cluster like,

./checontroller
---
(OR)
[source,sh]

---

Note	The application will by default run as daemon always, so if you wish to quit it run CTRL + C

In OpenShift Cluster

git clone https://github.com/kameshsampath/checontroller
make docker (1)
oc apply -f example/app.yaml (2)

1. build the docker image

2. Deploy the application in OpenShift, you see the logs of the checontroller deployment in OpenShift for whats happening

This will wait/scan for all available che pods,and fire REST calls to refresh the stack.

Important

The pod scanning is selected based on Pod labels deploymentconfig=che app=che application=che So when you deploy che, be sure to add these labels to the deployment/pod
