    --source-secret=<optional_secret(basic auth + crt)> \
    --build-env <build_environment_variables> \
    --context-dir=<dir_for_dockerfile> \

# change uploaded objects
oc edit <bc/dc/object_type>/<project_name>

# print out uploaded object
oc describe <object_type> <project_name>

## Template
# upload a template from file to a specific project
oc create -f <path_to_tmpl_file>{.yaml|.json} -n <project_name>

# convert a template file into objects (to stdout)
oc process <path_to_tmpl_file>{.yaml|.json}

# convert and upload the new built objects to project
oc process <uploaded_template_name> | oc create -f -

# create a template from uploaded objects
oc export all --as-template=<template_name> > <template_filename>
