Feature request: No clobber of existing environment variables #402
Comments
Looks like this might have been already requested: #87 I have forked and am keen to work on this |
Working prototype: https://github.com/mjsqu/chamber/tree/feat/no_clobber

Any movement here? This would be really useful for local development. |
When
chamber
is used to populate environment variables into a Elastic Container Services (ECS) task, you are able to add environment variables to the command usingcontainerOverrides
:However, if you are running a
chamber
command these environment variables are overwritten if they exist in the service.It would be good to be able to do:
And have chamber not overwrite and environment variables that are already set. An update to the way 'collisions' are handled in the code should achieve this.
To this end,
--noclobber
sits alongside the existing--pristine
and--strict
switches and should not be used with them as it works in the opposite way:--strict
and--noclobber
- Should raise an error, these switches do pretty much the opposite of each other,--strict
requiring the variables be set and--noclobber
telling chamber not to overwrite them--pristine
and--noclobber
- Should also error,--noclobber
is allowing existing values to come through,--pristine
explicitly prevents them from being inheritedThe text was updated successfully, but these errors were encountered:
