|

Provides 'k' (kubectl) and 'h' (helm) shorthands to the respective
|
||||
utility. These functions leverage redis and scwrypts environments to
|
||||
allow quick selection of contexts and namespaces usable across all
|
||||
active shell instances.
|
||||
|
||||
The scwrypts group 'kubectl' has simple selection executables for
|
||||
kubecontext and namespace, but also provides the library to enable
|
||||
enriched, use-case-sensitive setup of kubernetes context.
|
||||
|
||||
All actions are scoped to the current SCWRYPTS_ENV
|

currently : \\033[0;33m$SCWRYPTS_ENV\\033[0m
