vkube 2.0.0

VKube-CLI User-End

Vkube Command Tool For User

Install && Use

pip install vkube
vkube config -w GHCRToken/DockerhubToken=xxx
vkube deploy -f xxx/VKubefile.yaml

Run CLI Locally

Install virtualenv to run the CLI tool locally:

pip3 install virtualenv

Create virtual environment:

cd vkube-cli && virtualenv venv

Activate virtual environment:

source venv/bin/activate

Install CLI：

pip install -e .
vkube deploy -f xxx.yaml
vkube config -w GHCRToken=xxx

Deactivate virtual environment:

deactivate

Install CLI Globally from Source Code

Navigate to the repository root:

cd /path_to_project #directory containing setup.py
pip3 install -e . # may need to manually create ~/.vkube/config.yaml

or

pip3 install . # auto generates ~/.vkube/config.yaml

Install CLI with isolated dependencies:

pip3 install --user pipx
export PATH="$HOME/.local/bin:$PATH"
pipx install ~/path_to_project
pipx install --editable ~/path_to_project

Using vkube-cli

After installing locally, from the root path ("xxx/vkube-cli"):

1. Add DockerhubToken or GHCRToken:

vkube config -w DockerhubToken=dckr_pat_xxxx
vkube config -w GHCRToken=ghcr_xxx

2.Configure VKubefile.yaml

3.Deploy using:

vkube deploy -f ./VKubefile.yaml #can deploy from any directory by specifying VKubefile.yaml path

Export Dependencies

pip freeze > requirements.txt

Notes

When configuring VKubefile.yaml, the build image context is "." (current directory where command is executed):

vkube deploy -f .VKubefile.yaml

For example, if running from vkube_cli directory, the build context is vkube_cli. Using COPY app.py /app in Dockerfile will fail if app.py doesn't exist in vkube_cli.

Known Issues

1. Docker Not Running

If Docker isn't running, you'll see:

Error: Unable to connect to Docker. Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

2. Image Push Failures

Network issues may prevent image pushing:

Pushing image encountering error: [{'status': 'The push refers to repository [docker.io/yourusername/myapp]'}, {'errorDetail': {'message': 'Get "https://registry-1.docker.io/v2/": net/http: TLS handshake timeout'}, 'error': 'Get "https://registry-1.docker.io/v2/": net/http: TLS handshake timeout'}]

Release CLI to PyPI

Build Package

Ensure setuptools, wheel and twine are installed:

pip install setuptools wheel twine

Build package from project root:

python setup.py sdist bdist_wheel

This creates a dist/ directory containing .tar.gz and .whl files for PyPI upload.

Generate Version Number from Git Tags

Install:

pip install setuptools_scm

Use specific tag to release:

git fetch --tags
git checkout v1.0.0  # switch to v1.0.0 tag

Upload to PyPI

twine upload dist/* -u __token__ -p <your-pypi-api-token>
