All the questions about docker you wanted to ask but felt stupid asking

[Teodor]

Hi Brian,
I thought the answers of all these questions can be found in:

• Ultra fast web development with Docker in Wappler
• Web Development with Docker Part 2, Databases and Terminals
• Web Development with Docker part 3: Deploy to Remote Hosts
• Docker Part 4 - Deploy in Seconds to the Cloud with Docker Machines

I'll try to answer them separately, referring to these docs.

It’s a CMS, your live site has lots of images uploaded by users

My belief is that they are overwritten by the local copy?

So the solution is to use a mapped drive so the images are not overwritten?

Is there an alternative? (it’s another $10 per month)

If so, how?

It there any tutorial on this?

How do we deal with the new paths in components like image upload?

How do I set this up?

You just define a users upload folder in the project option. It will be used by docker to create user upload folders that remain persistent.

@Hyperbytes

Assuming the developer has kept the database structures in sync using the database manager the structures of your development and production databases will be identical

You have lots of new database entries in your live site from users uploading information.

So does the deploy overwrite this with the local database?

If so how do you preserve your production data preventing it from being overwritten

When deploying it only deploys the files. If you want to apply changes to your db schema, use the database manager > apply changes ...
George explains it here:

Here is the video of George’s Database Manager demo for those of you who missed the User Gathering!

Not sure if this fully answers your questions, but i believe all the answers are in the links i sent.
Also deploying with docker is much easier/faster than dealing with FTP and custom hosting providers
