Discuss maybe some pros and cons ```yaml apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig strategy: RelativeToBundle keep: Namespace|Image|Repositiry dashed: Namespace|Image|Repository ``` other.reg.io/some/bundle@sha... reg.io/my/team/one/image namespace == my/team/one keep: Namespace dashed: Namespace other.reg.io/some/my-team-one/image keep: Namespace other.reg.io/some/my/team/one/image Strategy: RelativeToRegistry keep: Namespace dashed: Namespace reg.io/my-team-one/image keep: Namespace other.reg.io/my/team/one/image Other Option: ```yaml apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig keep: Namespace|Image|Repository dashed: Namespace|Image|Repository relative: Bundle|Registry ``` Default case: ```yaml apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig keep: Image relative: Bundle ``` ```yaml apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig dashed: Namespace relative: Bundle ``` reg.io/my/team/name/img@sha:0 -> other.reg.io/some/my/team/name@sha:0 reg.io/my/team/name/img1@sha:1 -> other.reg.io/some/my/team/name@sha:1 ```yaml apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig keep: Namespace relative: Bundle ``` - Decide if we are going to postpone the ability to do overrides or not ### Open Questions/Help Needed: ~30-minutes * Kapp and Tekton working together (Charandas) https://github.com/vmware-tanzu/carvel-kapp/issues/77 * Would need to figure out what to do first and then who would work on it. Needs a lightweight proposal, list of options of what can be done here. [Dmitriy] * Will bring it up with rest of maintainers. * If interested in contributing to this issue, please reach out to us in Kubernetes Slack in [#carvel](https://kubernetes.slack.com/archives/CH8KCCKA5). --- # April 22, 2021 Agenda ### Working Group Session: This week's Office Hours will be primarily centered around [imgpkg-003 Rename images when copying bundles #22](https://github.com/vmware-tanzu/carvel-community/pull/22), which is a re-write of the proposal to address [Eli Wrenn's comment](https://github.com/vmware-tanzu/carvel-community/pull/22#discussion_r610195408). #### Goals: * Feedback on the document * Address other possibilities of creating strategies: * An example of that would be: *Also, is it really better to have different Strategies, than one single strategy with configuration options as values? (e..g)* ```bash-plain apiVersion: imgpkg.carvel.dev/v1alpha1 kind: CopyConfig strategy: KeepNamespace prependBundleName: True # Defaults to True ``` *As I’m not sure when people will really understand the difference a bundle will introduce so that he needs to change the strategy* ### Discussion Topics: (for next time) * Should we continue using GitHub discussions? How can we improve our process for discussions? [Here's](https://github.com/concourse/concourse/blob/master/CONTRIBUTING.md#contributing-to-concourse) what concourse does. --- # April 8, 2021 Agenda ### Discussion Topics: 30-minutes * New scenario on Copy with Rename Proposal for `imgpkg` [proposal url](https://github.com/vmware-tanzu/carvel-community/pull/22#issuecomment-815906327) ### Open Questions/Help Needed: ~30-minutes * <Replace with **your question or help needed**> ___ # March 25, 2021 Agenda ### Discussion Topics: 30-minutes * [[ytt] Bring back support for Starlark multi-line strings #327 ](https://github.com/vmware-tanzu/carvel-ytt/issues/327) * Example: [Community Issue Brought up in K8s Slack](https://kubernetes.slack.com/archives/CH8KCCKA5/p1616177776070200) * **Action Item:** Helen will prioritize this * [kbld] Should we support regex matching for images [#97](https://github.com/vmware-tanzu/carvel-kbld/issues/97) ### Open Questions/Help Needed: ~30-minutes * Pete: I have a project where I’m trying to take a helm chart as input, and rewrite all of the possible image references to a new registry (for purposes of using an unmodified chart to a private registry). I am wondering if there’s a way to do this with kbld or imgpkg, but they might not fit perfectly. # March 11, 2021 Agenda ### Discussion Topics: 30-minutes * Provide a way to add custom waiting functionality for resource types ([kapp #11](https://app.zenhub.com/workspaces/carvel-backlog-6013063a24147d0011410709/issues/vmware-tanzu/carvel-kapp/11)) * Dustin: I would prefer a string query vs complicated ytt or starlark * John: Explore the suggestion, write a proposal * Dmitriy: Proposal on possible approaches * Joao: Check with users on what they need first * <Add Your Discussion Item Here> ## Triage Help _Community suggestions requiring resolution._ - [ytt#260: GitOps friendly command for ytt](https://github.com/vmware-tanzu/carvel-ytt/issues/260) \ _Support "Application Groups" for `ytt` ala `kapp`._ **Action Item:** Cari to add in comments on past discussions surrounding this and if there is more discussion to be had, will add to next meeting. #### Did not have time to discuss - [*kapp#183: kapp should be a little more lenient for poorly formatted manifests when `kapp.k14s.io/versioned` is involved*](https://github.com/vmware-tanzu/carvel-kapp/issues/183)\ _*Versioned sub-functionality should succeed in deploying when iterating over null arrays*_ - [*kbld#97: Images present as args to a container command are not included nor substituted with kbld*](https://github.com/vmware-tanzu/carvel-kbld/issues/97) \ _Extend `kbld`'s image reference scanning capabilities to search _within_ a value._ ## Open Questions/Help Needed: ~30-minutes * [tylerrasor](https://github.com/tylerrasor) Cardinal Health, Dublin OH - Org's use case is loosely define by [this specific issue in concourse](https://github.com/concourse/concourse/issues/1994). Looking into how to solve the concourse reusability and templating. Not currently using Carvel, but ytt keeps coming up. * My biggest question is going to be about testing though… as far I’ve been able to research, there doesn’t seem to be a good way to take these templates -> ytt it -> assert output == expected * and we’d be using it in an internal project that would have multiple contributors from across different teams, so maintainability and change confidence is a huge deal ***Dmitriy:** [ytt Overlays](https://carvel.dev/ytt/#example:example-overlay-files) is a way to do the validation
