bug: devspace init fails with rendering error when using existing Helm chart in Go project environment

[mattwelke]

What happened?

When running devspace init on a directory for a Go project that already had a Helm chart, I get an error message and partially completed generated files after finishing the prompts.

I was trying to do this for a popular open source project that works this way (Go, has a Helm chart already). But I've created a minimal reproduction instead of referencing that open source project for this bug report.

The error:

fatal error rendering deployment: devspace render: exit status 1

The devspace_start.sh file:

#!/bin/bash
set +e  # Continue on errors

COLOR_BLUE="\033[0;94m"
COLOR_GREEN="\033[0;92m"
COLOR_RESET="\033[0m"

# Print useful output for user
echo -e "${COLOR_BLUE}

Welcome to your development container!

This is how you can work with it:
- Files will be synchronized between your local machine and this container
- Some ports will be forwarded, so you can access this container via localhost
- Run \`${COLOR_GREEN}go run main.go${COLOR_RESET}\` to start the application
"

# Set terminal prompt
export PS1="\[${COLOR_BLUE}\]devspace\[${COLOR_RESET}\] ./\W \[${COLOR_BLUE}\]\\$\[${COLOR_RESET}\] "
if [ -z "$BASH" ]; then export PS1="$ "; fi

# Include project's bin/ folder in PATH
export PATH="./bin:$PATH"

# Open shell
bash --norc

The devspace.yaml file:

version: v2beta1

dev:
  app:
    imageSelector: image
    ports:
      - port: 2345

What did you expect to happen instead?

DevSpace would initialize itself for my Go project with a pre-existing Helm chart.

How can we reproduce the bug? (as minimally and precisely as possible)

Create a test directory, create a new Helm chart within it, initialize the directory to be a Go module, run devspace init, and follow the prompts, specifying that you want it to use the existing Helm chart:

~ > mkdir devspace-test
~ > cd devspace-test/
~/devspace-test > helm create foo
Creating foo
~/devspace-test > go mod init example.com
go: creating new go.mod: module example.com
go: to add module requirements and sums:
	go mod tidy
~/devspace-test > touch main.go
~/devspace-test > devspace init

For me this was that I had no context, since I had removed my kind cluster. Check it with kubectl config current-context. The hint that helped me:

$ devspace deploy --render
warn Unable to create new kubectl client: Error loading kube config, context '' doesn't exist

ensure_pull_secrets: Please make sure you have an existing valid kube config. You might want to check one of the following things:

* Make sure you can use 'kubectl get namespaces' locally
* If you are using Loft, you might want to run 'devspace create space' or 'loft create space'

fatal exit status 1
