chartify's Issues

Value conversion error for fields

Hi

I am evaluating your code to convert my kubernetes yml to helm.
Working good, but few issues:

1. When converting, for Deployment Template spec, in ImagePullSecrets, in the output file, the "name" is converted to "Name". "n" to uppercase: for which helm fails.
   imagePullSecrets:
   • Name: my-pull-secret

I've few more issues, which i was able to fix in my local fork.

Is this repo still active? i will open a PR for few changes.

Pass namespace in separate flags while necessary

Example:
Do not pass <secret-name>.<namespace> in --secrets flag

Only service name can take <namespace> after it.

Deployments support

We're moving to helm and it'd be useful if we could chartify our deployments. I've solved it for the mean time by using replicasets to generate the charts and then editing them.

This is an awesome project, and I'd happily try adding deployments support.

Is there a reason this hasn't been added yet?

Otherwise I'll try make a PR this weekend.

Chartify entrire namespace

Where is the executible, how and where to run it from?

Did go get -u kubepack.dev/chartify from home directory.
ran chartify but no go.
ran locate chartify but no go.
OS: ubuntu 20
Some more documentation on how to install, use and execute would be of great help.

Turn into Helm plugin

Support new api versions

In Kube 1.6,

• Deployments changed from extensions/v1beta1 to apps/v1beta1.
• Jobs changes from v1alpha2 -> v1

These needs to be supported.

Ingress

May you please add the functionality of adding Ingress yaml file. As I have got this error Ingress is not supported. Please add manually.

Add Support for HorizontalPodAutoscaler

While creating helm chart for kubespec having "HorizontalPodAutoscaler" , getting below exception
HorizontalPodAutoscaler is not supported. Please add manually.

Retrieve resource types from the cluster instead of hard coding them

As a developer who works across a number of different Kubernetes cluster from a number of different vendors, and as a developer using Operators in K8s; I would like to have a way to convert existing resources of types not currently defined in this application.

For example, if using the Strimzi Operator for deploying Kafka clusters, I would want to be able to extract, templatize, and convert to a chart the Custom Resource Definitions for Strimzi.

type KubeObjects struct {

Endpoints - Kube Object Pls

Typically Storage with GlusterFS ends up with creating Kube EndPoints with Kube Service before getting consumed in PV / PVCs.
Can we have this Endpoint as well part of Chartify?

For e.g https://github.com/kubernetes/charts/blob/master/incubator/patroni/templates/ep-patroni.yaml Reverse of this pls!

Thanks in advance

Support Kubernetes RBAC objects

Dynamic selector in service

While creating charts, some labels are added dynamically. In the selector of service It need to be detected. It can be done by identifying those labels from the objects at the time of modifying the labels.

Blank basic templates

Configuration being overridden

I haven't worked on a simple reproduction, but it seems like you have services and replicasets with the same names, then the service config replaced the replicaset config in my values.yaml

Use $chart-$release as fullname

Should we change the full name form?

Update conventions followed by modern charts

Flag input parameter to preserve resources name in output

Can we have some flag to pass to Chartify, which can bypass name change for resources?

Ex.
--preserve-name true - will not change resources name in output. will be same as input.
It will solve most of the scenarios when working with secret combinations & local registry.

Fix space around `{{ `
