This is the GA version of the helm-x integration #673 developed last year.
You get all the following benefits without an extra helm plugin:
- Ability to add ad-hoc chart dependencies/aliases, without forking the chart (Fixes#876 )
- Ability to patch resulting K8s resources before installing the helm chart
- Ability to install a kustomization as a chart (Requires `kustomize` binary to be available in `$PATH`
- Ability to install a directory of K8s manifests as a chart
- etc.
The problem was that `--namespace NS` had been not taken into account while deleting releases, that resulted in releases that should be deleted are not deleted.
* fix: Fix `needs` to work for upgrades and when selectors are provided
Fixes#919
* Add test framework for `helmfile apply`
* Various enhancements and fixes to the DAG support
- Make the order of upgrades/deletes more deterministic for testability
- Fix the test framework so that we can validate log outputs and errors
- Add more test cases for `helmfile apply`, along with bug fixes.
- Make sure it fails with an intuitive error when you have non-existent releases referenced from witin "needs"
Introduces DAG-aware installation/deletion ordering to Helmfile.
`needs` controls the order of the installation/deletion of the release:
```yaml
relesaes:
- name: somerelease
needs:
- [TILLER_NAMESPACE/][NAMESPACE/]anotherelease
```
All the releases listed under `needs` are installed before(or deleted after) the release itself.
For the following example, `helmfile [sync|apply]` installs releases in this order:
1. logging
2. servicemesh
3. myapp1 and myapp2
```yaml
- name: myapp1
chart: charts/myapp
needs:
- servicemesh
- logging
- name: myapp2
chart: charts/myapp
needs:
- servicemesh
- logging
- name: servicemesh
chart: charts/istio
needs:
- logging
- name: logging
chart: charts/fluentd
```
Note that all the releases in a same group is installed concurrently. That is, myapp1 and myapp2 are installed concurrently.
On `helmdile [delete|destroy]`, deleations happen in the reverse order.
That is, `myapp1` and `myapp2` are deleted first, then `servicemesh`, and finally `logging`.
Resolves#715
