Automatically configure the host to support a development URL

[takielias]

👉 Describe the problem

Current Situation: As a WSL2 user, I've been using ddev for a few months and really like it. The only big downside is that it doesn't have features for deploying to a live server. However, ddev is great for local development; when I run ddev start, it automatically sets up a development server URL based on my project's folder name and updates the hosts file for me.

Limitation in Spin: Spin currently lacks this automated functionality, requiring manual modification of the hosts file and definition of the development server URL.

👥 Problem evidence & reach

Manual Configuration in Spin: After spinning up a project, you need to manually modify the hosts file and define the server URL, which is a cumbersome and potentially error-prone process, especially for those new to Docker.

🥰 Describe the "impact" on users?

User Experience Enhancement: Automating this process in Spin would greatly simplify the setup for new Docker users, reducing the learning curve and potential for configuration errors.

🏆 How to solve this problem

Investigation into ddev's Approach: While the exact solution is not known, a good starting point would be to examine how ddev implements this functionality. This could involve reviewing ddev's source code or its documentation to understand its method for automating these tasks.

Adaptation for Spin: Based on the findings from ddev, propose a method to integrate similar functionality into Spin. This might include scripting or leveraging existing tools within the Docker ecosystem.

💯 How do we validate the problem is solved?

Automated Setup in Spin: The solution would be validated if, after spinning up a project in Spin, the development URL is automatically generated, and the hosts file is modified accordingly for Windows users, without any need for manual intervention.

Hey @takielias,

Thanks for sharing!! I totally agree. The hosts file was an "MVP" approach that I took, knowing that I needed to come back to it.

I will review DDEV and see if there are any methods that they use to do this.

Whatever method it is, I want to be able to do it without root permissions (if possible) and make it very easy to centralize the management.

Hello @jaydrogers

I don't know if there will be a super automated way, however, without using spin, i believe it could work the same, i've used dnsmasq which worked alright. There's only one issue, if you have Laravel Valet running for some reason it causes conflicts with the config i've applied, unless i've fully stop Valet and it works.

Thanks for chiming in!

I've done this before. DNSMasq works great, but making it "auto-magic" is difficult because it requires root permissions and different configurations across MacOS, Windows, and Linux.

I was hoping to figure out a way where I could deploy a pre-configured DNSMasq container, but I don't want the container to handle ALL of the DNS name forwarding. Making it a conditional forward for Mac, Windows, and Linux without much user interaction would be the tricky part.

Yeah. If you have ideas i can help test as i've been also trying different things but nothing seems to work exactly how i would prefer (which is the more "auto-magic" way)
