# 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
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
```
and here's the help screen :
```
