The fragment variant of the URIs e.g. `foo: ref+awsssm://path/prefix#key` was not working. This change fixes that by bumping `vals` which is the library providing the SSM support, along with other dependencies.
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
- `replace` for thrift had to be removed to avoid the error `go: github.com/apache/thrift@v0.12.0 used for two different module paths (git.apache.org/thrift.git and github.com/apache/thrift)`
- Other dependencies are updated by running `go get -u github.com/variantdev/vals`
This change enhances helmfile to accept terraform-module-like URLs in nested state files a.k.a sub-helmfiles.
```yaml
helmfiles:
- # Terraform-module-like URL for importing a remote directory and use a file in it as a nested-state file
# The nested-state file is locally checked-out along with the remote directory containing it.
# Therefore all the local paths in the file are resolved relative to the file
path: git::https://github.com/cloudposse/helmfiles.git@releases/kiam.yaml?ref=0.40.0
```
The URL isn't equivalent to terraform module sources. The difference is that we use `@` to distinguish between (1) the path to the repository and directory containing the state file and (2) the path to the state file being loaded. This distinction provides us enough fleibiity to instruct helmfile to check-out necessary and sufficient directory to make the state file works.
Under the hood, it uses [hashicorp/go-getter](https://github.com/hashicorp/go-getter), that is used for [terraform module sources](https://www.terraform.io/docs/modules/sources.html) as well.
Only the git provider without authentication like git-credentials helper is tested. But theoretically any go-getter providers should work. Please feel free to test the provider of your choice and contribute documentation or instruction to use it :)
Resolves#347
Seems like we are affected by https://github.com/golang/go/issues/24963. That is, even though we internally use the template option `missingkey=zero`, in some cases it still prints `<no value>` instead of zero values, which has been confusing the state yaml parsing.
This fixes the issue by naively replacing all the remaining occurrences of `<no value>` in the rendered text, while printing debug logs to ease debugging in the future when there is unexpected side-effects introduced by this native method.
Fixes#553
Fixes#344 by allowing explicit selectors to be specified for composed helmfiles using the following structure
```yaml
helmfiles:
- path: helmfile.d/a*.yaml
selectors:
- name=prometheus
- name!=zipkin
- helmfile.d/b*.yaml
- path: helmfile.d/c*.yaml
selectors: {}
```
2 modes here :
* legacy mode when no the env var HELMFILE_EXPERIMENTAL is not set to true
* no selector : inherit from the command line.
* selector: is specified then it is used (an emty means no inheritance from command line and take everything).
* experimental when the env var HELMFILE_EXPERIMENTAL=true
* no selector : nothing is inherited from the command line so use all releases.
* selector: is specified then it is used (an emty means no inheritance from command line and take everything).
