You can set parameters on the commandline individually, like this:
wsk package update mypackage -p dbname awesomedb
This gets clunky once you have a few parameters, and you can’t add new parameters, whatever you use here will remove any previous params and overwrite. Instead I like to hold the parameters in a file, and edit it and update the action as needed.
Pro tip: you probably don’t want to store the parameters file in source control! Feed it to your deployment toolchain.
Parameters files should be formatted something like this (it’s JSON)
Then to supply this file (called
params.json) to the package:
wsk package update mypackage -P params.json
(that’s an uppercase
P not the lowercase one as in the earlier example)
You can use this approach to more easily repeat existing parameters, and just add/change what you need to.
Pro-tip: wondering what parameters are already set on this package? Use
wsk package get mypackage parameters to see :)
