Does the Docker method just work for everyone? Doesn't for me.

[amityweb]

Update: I have reported this as a bug #15916

I try to avoid Docker because over the years, every single time I use it it has some sort of errors I need to fix and it can me longer to fix them than if I were to set an app up without Docker.

Unfortunately with Saleor I am having a real hard time. I did deploy Saleor direct to Heroku last year by connecting Heroku to my Github fork. I use to update it that way and it always worked.

Now when I update it it breaks. Saleor say they dont support Heroku anymore, its Docker.

I dont know how to can migrate my app to Docker, it throws errors when I try, so I thought I would start from scratch.

The first hurdle is that "docker compose build" as per the instructions on this page https://docs.saleor.io/docs/3.x/setup/docker-compose throws a version error and stops. Removing the version line then it just does nothing. Absolutely nothing.

Verbose output just says:
DEBU[0000] Enabled Docker Desktop integration (experimental) @ unix:///Users/me/Library/Containers/com.docker.docker/Data/docker-cli.sock

So instead of building from the files from Github, within Docker I search for Saleor in the repos there and find the mirumee/saleor one and it does download and builds the image OK. I do have to specify a port when I run it, else there is no port assigned and localhost does not work. When I assign a custom port it works.

But when i run it, the webpage and logs show the following error in that it cannot connect to port 5432 (I think postgres)

Did you checked Saleor Platform it always work for me

also i have a slightly modified version of saleor-platform, i meant it to be a production ready docker-compose setup Saleor Stack

[amityweb]

Saleor make it clear Saleor Platform is not for production. It's strange though, because their Saleor instal documentation says use that.

[amityweb]

I think its working for me OK when I use Saleor Platform, and I expected something visible to happen when I typed "docker compose build" but nothing did. But if I proceed with the instructions it seems work then. I guess the issue above was I was only using Saleor Core but expected the database to be setup inside also? Maybe its not.

[amityweb]

I am using Saleor Platform though, not each individual setup they recommend. I wonder why they say it should not be used for production?
