Use helm in the devops-toolkit

Prerequisite

Familiar with the kubectl_usage first so we can have the correct k8s integration

Helm document

Some document to help you start with helm

Run with devops-toolkit-cli

Start the container

Navigate to your workspace folder, then run:

devops-toolkit-cli init demo_helm01
devops-toolkit-cli run demo_helm01

# You now in the container terminal. Execute the helm command normally
helm --version

It will mount the workspace code to container and you then can execute desired scripts inside the devops-toolkit container.

Run with Docker command

Note

To use the existing container instead of creating one, use docker exec command instead of docker run

docker exec -it my_devops_toolkit /bin/bash

Common Run Modes

For instructions on common run modes, visit DevOps Toolkit Common Run Mode.

Use case 1: Deploy an application with Helm

docker run --rm --network host -it -v ~/.dtc:/dtc tungbq/devops-toolkit:latest
