Docker-Stack | repo contains a simple Docker setup | Continuous Deployment library

So in my case I've previously ran Airflow locally directly on my machine and now I'm trying to run it through containers using docker while also keeping the history of my previous dags. However I've been having some issues.
A slight bit of background ... when I first used docker-compose to bring up my containers airflow was sending an error message saying that the column dag_has_import_errors doesn't exist. So I just went ahead and created it and everything seemed to work fine.
Now however my dags are all broken and when I modify one without fixing the issue I can see see the updated line of code in the brief error information that shows up at the top of the webserver.
However when I resolve the issue the code doesn't change and DAG remains broken. I'll provide
this image of the error
this is the image of the code\

also the following is my docker-compose file (I commented out airflow db init but may I should have kept it with the db upgrade parameter as true? My compose file is based on this template\

I'm creating a dev environment to use airflow for testing. I'm using the docker-compose.yaml file available on Airflow website. I would like to know if it is possible to set my connections and variables in this file. I know that I can establish a connection using AIRFLOW_CONN_... with URI parameters. Is it possible use AIRFLOW_CONN_... and EXPORT VARIABLE inside the docker-compose.yaml file?

My docker-compose.yaml file:

I'm trying to run an airflow image using docker. A while ago it was working normally. However, I ran other applications on localhost without using docker (using VisualStudio) and when I rerun my airflow after that, localhost was no longer working.

I've tried to reinstall Docker and AirFlow imagem, but no success.

I'm using Airflow 2.1.4 docker imagem available on Apache website.

My AirFlow is set to run on localhost:8080. Is there a way to know if another application is using 8080?

I don't know what necessary information I can post here to clarify my problem. I believe that checking if there is other application binded to run on localhost:8080 (either an instance of visual studio or the docker itself) can solve the problem. But how to do this?

My docker-compose.yaml file:

The background is, I'm responsible for maintaining a fancy Docker image that is used by our team for analytics. It uses a Jupyter notebook image as the base, and then adds various customisations, extra packages, etc.

One of the team members recently wanted to run Tensorflow. No problem, I'll just run mamba install and add it to the image. However, this created an issue: Tensorflow 2.4.3 (the latest version) is somehow incompatible with R 4.1.1 (also the latest version) or something else in the ecosystem, causing R to to be downgraded to 3.6.3. So I created a new environment and installed TF into that:

I have a website where I document a list of installed pythonic libraries.

For each library, I want to have available:

• The name of the library (obviously)
• A link to the documentation for the library (because documentation is useful)
• A brief description of the library (so people can quickly see what the library does)
• The currently installed version (to stop people asking me "Are you using version x.y?")

My current solution is to use the name as the text of a link, href'd to its documentation, and accept that the version & description are supplementary information, and can be made available to the user using a tool-tip - so they can sit in a title attribute

Example:

I need use a few .ps1 from a project to make build and deploy in another. I try this:

repo with the .ps1 (its public and this repo have test2.ps1 and test3.ps1):

https://lgitlabn01vpr.xxx.com/user/test_clone

and this is the repo that needs the script to build and deploy

https://lgitlabn01vpr.xxx.com/mariano_prueba_2

in "mariano_prueba_2" i have:

dockerfile:

I want to deploy Django Application with Docker Swarm. I was following this guide where it does not use the docker swarm nor docker-compose, and specifically created two Django containers, one Nginx container, and a Certbot container for the SSL certificate. The Nginx container reverse proxy and load balance across the two Django containers which are in the two servers using their IPs

I know this is a duplicate of this, but since that was never answered, I am re-posting this question.

I am trying to build a basic connection of php-apache and mysql containers.

I am trying to update an interactive matplotlib figure while in a loop using JupyterLab. I am able to do this if I create the figure in a different cell from the loop, but I would prefer to create the figure and run the loop in the same cell.
