helm-py's Issues

Helm pull command construction seems to be wrong

Dear maintainer,

As I started using this library, I discovered another issue, this time with helm pull. Here is my code:

from helm_wrap import helm


def download_charts(source_repo, source_chart):
    chart_name = source_chart
    source_chart = helm.Helm()
    source_chart.pull(chart=chart_name, repo=source_repo)

It uses the pull method to pull a chart locally. However, what ends up happening is the following:

CompletedProcess(args=('/usr/local/bin/helm', 'pull', '--chart=cluster-autoscaler', '--repo=https://kubernetes.github.io/autoscaler'), returncode=1, stdout='', stderr='Error: unknown flag: --chart\n')

That is because the following wrong command gets constructed:

helm pull --chart=cluster-autoscaler --repo=https://kubernetes.github.io/autoscaler

instead of the right one:

helm pull cluster-autoscaler --repo=https://kubernetes.github.io/autoscaler

I tried to find out where the bogus --chart= flag is coming to prepare a fix from but I did not succeed.

ImportError: cannot import name 'ExecWrapper' from 'wrapper' (/home/UserName/.local/lib/python3.10/site-packages/wrapper/__init__.py)

Hi,

I really like the library, looking at the objects it does exactly what I want. However, I have a bit of an issue with the dependencies.

I am on:

python3 --version
Python 3.10.12

I import the package and initialize the class into an object like so:

from helm_wrap import helm

def helm_template(helm_chart):
    helm_chart = helm.Helm()
    helm_chart.template()

Although when I run the code I run into this error:

/bin/python3 /home/myuser/codebase/project-helm-docker/helm_template.py
Traceback (most recent call last):
  File "/home/myuser/codebase/project-helm-docker/helm_template.py", line 2, in <module>
    from helm_wrap import helm
  File "/home/myuser/.local/lib/python3.10/site-packages/helm_wrap/helm.py", line 1, in <module>
    from wrapper import ExecWrapper

I have the wrapper dep installed by pip:

pip install wrapper
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: wrapper in /home/myuser/.local/lib/python3.10/site-packages (1.1.0b1)

Could you lend a hand please?
