I'm try to run 2 Spring Boot applications within the same Pod (essentially one is a reverse proxy for the other one - a small implementation of the sidecar pattern) and I've that one of the containers can't start. In fact, it crashes with the following error:

I deployed a Django app in a K8s cluster and have some issues with the routing by Ingress.

I am trying to deploy a Vue app in the frontend and the .net core api in the backend. Using docker-compose file I have been to able to spin up the network and containers but I am struggling to have them communicate. I am pretty new to docker however, do understand that the Vue app dockerfile uses an Nginx base to feed the web app but it seems that may be affecting the network communication as the frontend container does not resolve the backend container name though it should since they are in the same virtual private network with the default bridge driver. When executing a bash shell in the frontend container and doing a curl to the backend container, I do get the correct response.

I did try to expose the backend container to the host and then use the server IP to reach it from the frontend and that does work however, I was hoping to not have to expose my api this way and wanted to make it work through the docker virtual private network if possible.

Example url I am trying in the frontend which encounters a name not resolved error: littlepiggy-api/api or littlepiggy-api:5000/api

I'm having trouble to config my Laravel application to run on my web server.

The problem is that I'm getting the Welcome to nginx! page and not my laravel app when using the browser.

The set up is the following

• It's a server running on Ubuntu 20.04 LTS
• The nginx service is installed directly on the machine (not using docker)
• I have a docker-compose to run 3 containers: postgres (database) + keycloak (auth server) + My laravel app.

Keycloak and the postgres db are running like charms for months.

Laravel app path -> /var/www/dev.mycompany.com/

Laravel Dockerfile -> /var/www/dev.mycompany.com/Dockerfile

I am building an Alpine based image of a Django application to connect with a MySQL db. For connecting with the database, I am using mysqlclient. For building the image, I am using docker-compose. When I do docker-compose build I get the respective error:

I have a web application built with Codeigniter. I recently implemented Docker in the application on the localhost. Now how do I deploy modified application and the docker containers on the server.

I have provided my docker-compose file below.

I'm new to docekr and I'm setting up a Codeigniter docker image on my local machine bitnami/codeigniter:3

Everything works fine but the mysql container looses it's DB and all the data everytime I perform sudo docker-compose down

This is docker-compose file
