Overview

Internet connection and DNS routing are broken from WSL2 instances, when some VPNs are active. The workaround breaks down into two problems:

1. Network connection to internet
2. DNS in WSL2

This problem is tracked in multiple microsoft/WSL issues including, but not limited to:

• microsoft/WSL#5068

  class Application < Rails::Application
    if Rails.env == 'test'
      require 'diagnostic'
      config.middleware.use(MyApp::DiagnosticMiddleware)
    end

export DOCKER_EMAIL=Type your dockerhub email, same as when you `docker login`
export DOCKER_PASSWORD=Type your dockerhub pw, same as when you `docker login`

kubectl create secret docker-registry myregistrykey \
  --docker-server=$DOCKER_REGISTRY_SERVER \
  --docker-username=$DOCKER_USER \

Caveats

Remember that using vue jsx has some caveats. Most importantly that most vue builtin directives are not supported (for example, v-for, v-model, etc.), expect for v-show. Some of them can be implemented manually, but v-model for example is kind of a pain in the ass.

https://github.com/vuejs/babel-plugin-transform-vue-jsx#vue-directives
There's this though:

Also the sourcemap result is kind of crappy, things like @ are not mapped correctly, I resorted to just using 'eval' as webpack config.devtool, it's good enough for what I'm doing.
