vals v0.3.0 introduces the terraform output source that can be accessed by `ref+tfstate://path/to/tfstatefile/type.resourcename.prop` syntax. Please see the updated README section of vals for more info.
since mergo had been bumped to 0.3.9 an environment value like:
```
affinity: {}
```
was not merged properly (not merged at all) instead it threw an error
that it cannot find the key "affinity" in the environment values even
though it was outputted in debug output as read in properly.
Enhances Helmfile to print more helpful message on error while calling `exec` template function.
Helmfile has been printing error messages like the below:
```
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sha" (list)>: error calling exec: exit status 1
```
Adding captured stdout and stderr, with some indentation to make it readable, it now produces the following message on missing executable:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sha" (list)>: error calling exec: fork/exec ./exectest.sha: no such file or directory
COMMAND:
./exectest.sha
ERROR:
fork/exec ./exectest.sha: no such file or directory
```
On non-zero exit status without output:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sh" (list)>: error calling exec: exit status 1
COMMAND:
./exectest.sh
ERROR:
exit status 1
```
On non-zero exit status with output:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sh" (list)>: error calling exec: exit status 2
COMMAND:
./exectest.sh
ERROR:
exit status 2
COMBINED OUTPUT:
out1
err1
```
Resolves#1158
`--retain-values-files` prevents temporary values files that were passed to Helm commands run by Helmfile for debugging purpose.
With that, you can manually rerun helm commands that were logged when `--log-level=debug` is enabled.
Resolves ##1117
* Add option to suppress diff on apply
Add --supress-diff option on apply. Usable for fresh installs when a
lot of output is produces by diff.
Resolves#458
* fix tests for suppress-diff
When chart is not set, an exception without any hints occure due
normalizeChart tries to access the first character of a 0 length string.
Properly inform user of missing chart.
This makes it possible to pass the API Capabilities to helmfile when executing a task that does not render against an actual cluster (diff, template, apply).
