# Use this script to run one-off commands inside a container of a pod where your
|
|
# Python application code lives in.
|
|
|
|
# You can accomplish the same results by using regular commands from OpenShift.
|
|
# This script is just wrapping calls to `osc` to make it a little more
|
|
# convenient to use. In the future, the `osc` cli tool might incorporate changes
|
|
# that make this script obsolete.

# Usage examples:
|
|
#
|
|
# ./run-in-container.sh ./manage.py migrate
|
|
# ./run-in-container.sh ./manage.py createsuperuser
|
|
# ./run-in-container.sh ./manage.py shell
|
|
#
|
|
# If your Python pods are labeled with a name other than "django", you can use:
|
|
#
|
|
# POD_NAME=name ./run-in-container.sh ./manage.py check
|
|
#
|
|
# If there is more than one replica, you can also specify a POD by index:
|
|
#
|
|
# POD_INDEX=1 ./run-in-container.sh ./manage.py shell
|
|
#
|
|
# Or both together:
|
|
#
|
|
# POD_NAME=frontend POD_INDEX=2 ./run-in-container.sh ./manage.py shell
|
|
|
|
|
|
# Get name of a currently deployed pod by label and index
|
|
POD_INSTANCE_NAME=`osc get pods \
|
|
-l "name=${POD_NAME:-django}" \
|
|
-t "{{ with index .items ${POD_INDEX:-0} }}{{ .metadata.name }}{{ end }}"`
|
|
|
|
# Run command in a container of the specified pod:
|
|
osc exec -p "$POD_INSTANCE_NAME" -it -- bash -c \
|
|
"cd \$HOME && source scl_source enable python33 && ${@:-echo}"
