Add regex support in filters

[moflotas]

There is currently no way of filtering components by name, when deploying. I have 2 cases that this feature would resolve

Deploying multiple instances of same kind

I am working on the database project. I have 2 ConfigMaps in one component, first one is for the app configuration (when updated, the app should be redeployed), the second is storing the index fields for the database (when updated, the app can automatically fetch new updates from the file). So I somehow need to be able to deploy 2nd ConfigMap separately from the first, however I didn't find a way to filter same kind of k8s objects.

Deploying to particular availability zone

Sometimes there is a need to deploy component only in one availability zone for testing purposes and then deploy to all zones. This can be mitigated with the proper configuration in jsonnet, but it would be easier to just filter components by zone name.

Hope this feature would also benefit other users, since filtering by regexp will allow users to more gradually make deployments using qbec.

@michael-burt are there any ways to promote code reviews?

Hi @moflotas , thank you for the contribution.

Have you tried using an ext-var for this use case? I believe it would allow you to accomplish your goal of conditionally deploying your second configMap.

https://qbec.io/userguide/usage/runtime-params/#using-qbecioenv

You can use a syntax like this: qbec apply dev --vm:ext-str enable_configmap=true

In your component you can reference this variable like this:

local enableConfigmap = std.extVar('enable_configmap');

Hi, @michael-burt , thank you for the response!

I believe it does not solve my problem, probably my example was not clear, I will try to explain better.

So I have a component which is made of k8s Deployment and 2 ConfigMaps (there are ingresses and other stuff, but they does not matter for the explanation). Sometimes I need to change only one part of the component (2nd ConfigMap) without redeploying Deployment and changing 1st ConfigMap (even if there is a diff between local and remote).

I do not understand, how using your suggestion would allow me to not include some parts of the component for diff evaluation. I can only imagine conditionally include/exclude component, but that would remove it from the remote and it is not what I desire to accomplish.
