E-Voting-App | simple E-voting Decentralised App | Blockchain library

I am trying to understand the docker sample application 'example-voting-app'. I am trying to build the app with docker-compose. I am confused with the behaviour of 'command' key in docker compose file and the CMD Instruction in Dockerfile. The application consists of a service called 'vote'. The configuration for the vote service in docker-compose.yml file is:

I am new to both docker and azure container services. I am trying to deploy a docker web app in the Azure Web App for Containers as single container instance. I am using the azure-vote-front image provided here. I followed the steps provided here after tagging and pushing the docker image in an Azure container register.

But after deploying the web app and navigating to the web url, all it shows is 502 Bad Gateway with nginx/1.15.8 mentioned below. Is there addtional configuration, I need to mention in any file or configure anywhere?

I'm fairly new to Kubernetes, and I am trying to get SEQ up and running in im the environment. Everything looks like its provisioned correctly, but I can not seem to hit the endpoint. Chrome just spins and eventually says ERR_CONNECTION_TIMED_OUT.

I tried another example from microsoft and it works correctly. I can hit it from the outside world.

Here is my yaml file:

I previously asked the almost same question. But the answer wasn't that good or just not good enough. I wanted to start again and now I have a lot of problems.

Here is the post.

Making a database-voting app

So for now I have another idea.

This time there is only one value which counts the votes, but the app don't get the actual amount of the value "count".

Here is my code:

I installed from here a simple training application https://github.com/dockersamples/example-voting-app

After that i want to remove working containers and then images of this app. I`m trying type this:

I'm working through a tutorial on Kubernetes on Azure tutorial (here) and everything has worked perfectly until I run the kubectl apply to configure the cluster:

I was following the tutorial Continuous deployment with Jenkins and Azure Container Service To integrate Jenkins on Azure and set it up to work with my container registry and kubernetes.

Manually, I run the commands for creating the resource group. These commands (starting from line 10).

The command on line 26:

az vm extension set --publisher Microsoft.Azure.Extensions --version 2.0 --name CustomScript --vm-name $virtualMachine --resource-group $resourceGroup --settings '{"fileUris": ["https://raw.githubusercontent.com/Azure-Samples/azure-voting-app-redis/master/jenkins-tutorial/config-jenkins.sh"],"commandToExecute": "./config-jenkins.sh"}'

, executes the following script:

This is probably going to be really embarrassing. I have file structure as follows.

I am following the code at https://github.com/Jastor11/node-express-firebase-voting-app/blob/master/views/home.ejs

This project also uses express but with ejs instead of hbs. I don't think that should be relevant though.

From login.hbs in views folder I am doing this

I was setting up some materials for a trainning, when I came around this sample compose file:

https://github.com/dockersamples/example-voting-app/blob/master/docker-compose.yml

and I couldn't find out how this volume is mounted, on lines 48 and 49 of the file:
