Will be tested locally on my Github codespace console and deployed to check if it works.

@Abdur-rahmaanJ Can you give me a list of environment variables that the application needs to run? My plan is to feed the docker image a .env file while starting it. What do you think?

@kfields You can check it out too.

[Abdur-rahmaanJ]

@teezzan we are currently using instance/config.py. Have you ever heard of instance/ in Flask?

[teezzan]

Not at all. Have you any link to it? Maybe how I can integrate it with Docker.

[teezzan]

I will probably just allow the user to pass in a .env file or config.py then move it into the newly created /instance folder.

[Abdur-rahmaanJ]

@teezzan https://flask.palletsprojects.com/en/2.0.x/config/#instance-folders ok that sounds good. See readme, we are creating an instance folder then adding config.py file

Btw are you on the Pallets discord?

[teezzan]

@Abdur-rahmaanJ Thank you. Please share with me a link to the Pallets Discord channel.

Let's remove this.

[michaelbukachi]

Do we need to add dev requirements if the docker image will only be used for deployments?

[teezzan]

Thanks. I think I don't need to add maildev to the services too. Since it is only for deployment. Is that okay?

[teezzan]

But it leads to a series of problems. First one is that the application can't find Faker when it starts.
I removed the initialise command and the seeding command because they were raising errors about things that are Dev dependencies not found. What do you say about this?

[kfields]

Nice! Some competition. However I'm getting errors

WARNING: The MYSQLDB_ROOT_PASSWORD variable is not set. Defaulting to a blank string.
WARNING: The MYSQLDB_DATABASE variable is not set. Defaulting to a blank string.

ERROR: The Compose file './docker-compose.yml' is invalid because:

You need to use a .env file or a combination of .env and env_file:

env_file can only set environment variables inside a service container. Variables from env_file cannot be injected into docker-compose.yml itself.

I encountered the same problem, so I quit using env_file. Now that I understand more fully I might use a combination of .env and env_file

[teezzan]

@kfields, I had the same issue. I simply stopped using the .env file for now.

[teezzan]

@Abdur-rahmaanJ @michaelbukachi The final error that I have is the inability to connect to the SQL server instance. I am trying to debug that as we speak.

[kfields]

Put the dev stuff back in. We can write a production configuration later. It won't even run because it can't find 'faker'

COPY dev_requirements.txt /app
RUN pip install -r dev_requirements.txt

PS: I'll look into your MySQL problem

[Abdur-rahmaanJ]

@teezzan great!!! waiting for it to finish

[Abdur-rahmaanJ]

Btw we dont need nodejs for tests.

[teezzan]

It was a mistake 😂. I Am still unable to connect to the SQL server instance created by docker compose. Every other thing works. I might need a little bit of help at this point. If you are available for a joint troubleshooting, let me know. @kfields @Abdur-rahmaanJ
