# helm-import
|
|
|
|
A tool to take a deployed set of kubernetes resources and turn them into a helm release.
|
|
|
|
Only works with helm3 > 3.2.0
|
|
|
|
Only compiles with Go < 1.15
|
|
|
|
And it's a pain to cross-compile, and my ci is currently broken
|
|
|
|
You can add jq commands to tweak the generation.
|
|
|
|
You run it from the chart folder (the one with `Chart.yaml`) in it
|
|
|
|
It's fairly opinionated but that can be turned off.
|
|
|
|
There's some kinda hacky stuff in the code related to json->yaml->helm stuff.
|
|
|
|
so... erm here's a docker command that worked for me :
|
|
|
|
```
|
|
docker run -v $(pwd):/context -v $HOME/.kube:/root/.kube --rm -it -w /context/ imartyn/helm-import /helm-import -namespace some-namespace -deployment some-deployment
|
|
```
|
|
|
|
