Bump Kubetail

Bump Kubetail Skill

Bump the kubetail components (dashboard, cluster-api, cluster-agent) to their latest releases and update config variables as needed.

Context

The helm-charts repo manages the kubetail Helm chart with three main components:

The source code is available at https://github.com/kubetail-org/kubetail. Git tags follow the pattern <component>/v<semver> (e.g., dashboard/v0.10.1, cluster-api/v0.5.3, cluster-agent/v0.6.2).

Runtime config for each component is rendered via Helm ConfigMap templates:

Steps

1. Ensure the helm-charts branch is up-to-date

First, determine which remote points to kubetail-org/helm-charts:

git remote -v | grep 'kubetail-org/helm-charts.*fetch'

Use that remote name (e.g., origin, upstream, etc.) for all subsequent commands. Call it <remote>.

Then run in parallel:

• git fetch <remote>
• Check the current branch name with git branch --show-current

Then check if the current branch is behind <remote>/main:

git log HEAD..<remote>/main --oneline

• If there are commits the current branch doesn't have, warn the user and stop -- they should rebase/merge before proceeding.

2. Determine current versions

Read charts/kubetail/values.yaml and extract the current image tags:

• kubetail.dashboard.image.tag (e.g., "0.10.1")
• kubetail.clusterAPI.image.tag (e.g., "0.5.3")
• kubetail.clusterAgent.image.tag (e.g., "0.6.2")

3. Find latest versions

Use the GitHub API to list tags for each component:

gh api repos/kubetail-org/kubetail/git/matching-refs/tags/dashboard/v --jq '.[].ref' | sed 's|refs/tags/dashboard/v||' | grep -v '\-rc' | sort -V | tail -1
gh api repos/kubetail-org/kubetail/git/matching-refs/tags/cluster-api/v --jq '.[].ref' | sed 's|refs/tags/cluster-api/v||' | grep -v '\-rc' | sort -V | tail -1
gh api repos/kubetail-org/kubetail/git/matching-refs/tags/cluster-agent/v --jq '.[].ref' | sed 's|refs/tags/cluster-agent/v||' | grep -v '\-rc' | sort -V | tail -1

Take the highest non-rc version for each component.

4. Check for config changes

For each component where the version has changed, use the GitHub compare API to diff the config struct between the old and new tags:

Dashboard (Go):

gh api repos/kubetail-org/kubetail/compare/dashboard/v<old>...dashboard/v<new> --jq '.files[] | select(.filename == "modules/dashboard/pkg/config/config.go") | .patch'

Cluster API (Go):

gh api repos/kubetail-org/kubetail/compare/cluster-api/v<old>...cluster-api/v<new> --jq '.files[] | select(.filename == "modules/cluster-api/pkg/config/config.go") | .patch'

Cluster Agent (Rust):

gh api repos/kubetail-org/kubetail/compare/cluster-agent/v<old>...cluster-agent/v<new> --jq '.files[] | select(.filename == "crates/cluster_agent/src/config.rs") | .patch'

Also fetch the current config struct at the new tag and read the current Helm ConfigMap template + values to understand all available options:

gh api repos/kubetail-org/kubetail/contents/<path>?ref=<component>/v<new> --jq '.content' | base64 -d

5. Assess config changes

For each config diff:

• If the diff is empty or only contains trivial changes (comments, formatting), proceed to image tag updates.
• If there are new config fields: check if they map cleanly to existing runtimeConfig values structure. If the new fields can be added as simple key-value pairs under the existing runtimeConfig hierarchy, propose the additions.
• If there are removed config fields: propose removing them from runtimeConfig in values.yaml.
• If the config changes require non-trivial template modifications (new template logic, conditionals, structural changes to ConfigMap rendering, new Kubernetes resources, etc.): stop and tell the user that a manual chart update is needed. Explain what changed and why it can't be handled by a simple bump.

Collect all proposed config changes and present them to the user for approval before making any edits. Show a clear diff-like summary of what will change.

6. Apply approved changes

After the user approves (or modifies) the config proposals:

1. Update image tags in charts/kubetail/values.yaml -- replace the old tag value with the new one for each component that changed.

2. Apply config changes to charts/kubetail/values.yaml -- add/remove/modify runtimeConfig fields as approved.

3. Update charts/kubetail/Chart.yaml — determine the bump severity by looking at the semver change across all components:

   • If any component has a major version bump → bump appVersion and version major.
   • If any component has a minor version bump → bump appVersion and version minor.
   • If all component changes are patch only → bump appVersion and version patch.

   Both version and appVersion get the same bump level and stay in sync.

7. Report

Summarize what was changed:

• List each component: old version -> new version (or "no change")
• List any config keys added or removed
• Note the new chart version and appVersion

Rules

• NEVER skip the user approval step for config changes.
• Only bump components where the latest tag is newer than the current version.
• If a component is already at the latest version, mention it but make no changes.
• Exclude release candidate tags (those containing -rc) when determining the latest version.
• If config changes require non-trivial template modifications, bail out and explain what needs to be done manually.
• Make best-effort guesses for new config values based on context (existing config patterns, field names, defaults in the source struct). Acknowledge uncertainty where it exists.
• Do NOT guess secret values -- for fields that are clearly secrets (keys, passwords, tokens), note them as <REPLACE_ME> and call them out to the user.
• When reading Go config structs, pay attention to validate:"required" tags -- these fields must have values.
• When reading Rust config structs, pay attention to #[serde(default)] and Option<T> types to determine which fields are optional.
• Run all independent git/read operations in parallel for speed.
