oc-context

A script to login and manage different OpenShift clusters in your terminal.

Dependencies

This scripts needs oc-select (https://github.com/webner/oc-select) and if you want to use client certificates openssl.

Installation

mkdir -p $HOME/.local/bin
cd $HOME/.local/bin
wget -q https://raw.githubusercontent.com/webner/oc-context/master/oc-context
chmod +x oc-context

Add $HOME/.local/bin to your PATH.

export PATH="$PATH:$HOME/.local/bin"

Usage

$ oc-context help

usage: oc-context <cmd>|<context>
--------------------------------------------
help              show usage information
list              list all availabe contexts
create <context>  create a new context
edit <context>    edit config
delete <context>  deletes a context
[use] <context>   use a context
create-cert       create user certificate

Create a new OpenShift context

The configuration for a context is stored in the file $HOME/.config/oc-context/$OC_NAME/env. With the following command a new context dev will be created and the env file will be opened in your $EDITOR.

$ oc-context create dev

Import an OpenShift context

The preferred way to create new context is to first connect to the OpenShift cluster and than run the import command. With this method most of the settings will be automatically discovered.

$ oc login
$ oc-context import dev

Use an OpenShift context

$ oc-context dev

  • Set KUBECONFIG to $HOME/.config/oc-context/$OC_NAME/.kubeconfig
  • Print all exported variabled beginning with "OC_"
  • Login to the cluster with client certificate or password.
  • Fork a new $SHELL

Show current context in your shell

For ZSH add following to $HOME/.zshrc

export PROMPT="$OC_CONTEXT_INFO$PROMPT"

For Bash add following to $HOME/.bashrc

export PS1="$OC_CONTEXT_INFO$PS1"
