What is this?

remotexec will connect to a Kubernetes master node using SSH and will fetch the node list using kubectl.
Once the node list has been created, it will execute a script on each node.

Usage

To use this application, there are a number of prerequisites:

• All Kubernetes nodes MUST support SSH key authentication with the same user
  
• The SSH user MUST be able to run the command 'kubectl get nodes'
  

Run the application:

docker run -it -p 5000:5000 rtortori/remotexec

or daemonized, if you want:

docker run -itd -p 5000:5000 rtortori/remotexec

That's it. Connect with your browser to: http://127.0.0.1:5000

Frequently used scripts

In the sample_scripts folder, you will find a collection of scripts that can be run on all Kubernetes nodes.
A frequent use case is to configure the docker daemon to use an HTTP proxy, without altering the Cisco Container Platform tenant image.
