OPENSHIFT CLI SET(1)

NAME

openshift cli set env - Update environment variables on a pod template

SYNOPSIS

openshift cli set env [OPTIONS]

DESCRIPTION

Update environment variables on a pod template or a build config

List environment variable definitions in one or more pods, pod templates or build configuration. Add, update, or remove container environment variable definitions in one or more pod templates (within replication controllers or deployment configurations) or build configurations. View or modify the environment variable definitions on all containers in the specified pods or pod templates, or just those that match a wildcard.

If "--env -" is passed, environment variables can be read from STDIN using the standard env syntax.

OPTIONS

--output-version=""
    Output the formatted object with the given group version (for ex: 'extensions/v1beta1').

--overwrite=true
    If true, allow environment to be overwritten, otherwise reject updates that overwrite existing environment.

--sort-by=""
