QUESTION
I have a local Kubernetes install based on Docker Desktop. I have a Kubernetes Service setup with Cluster IP on top of 3 Pods. I notice when looking at the Container logs the same Pod is always hit.
Is this the default behaviour of Cluster IP? If so how will the other Pods ever be used or what is the point of them using Cluster IP?
The other option is to use a LoadBalancer type however I want the Service to only be accessible from within the Cluster.
Is there a way to make the LoadBalancer internal?
If anyone can please advise that would be much appreciated.
UPDATE:
I have tried using an LoadBalancer type and the same Pod is being hit all the time also.
Here is my config:

As an example, let's say that I'm building a simple social network. I currently have two services:
Identity
, managing the users, their personal data (e-mail, password hashes, etc.) and their public profiles (username) and authenticationSocial
, managing the users' posts, their friends and their feed
The Identity
service can give the public profile of an user using its API at /api/users/{id}

ANSWER
Answered 2021-May-10 at 18:01In general, I strongly favor state replication via events in durable log-structured storage over services making synchronous (in the logical sense, even if executed in a non-blocking fashion) queries.
Note that all systems are, at a sufficiently high level, eventually consistent: because we don't stop the world to allow an update to a service to happen, there's always a delay from update to visibility elsewhere (including in a user's mind).
In general, if you lose your datastores, things get ruined. However, logs of immutable events give you active-passive replication for nearly free (you have a consumer of that log which replicates events to another datacenter): in a disaster you can make the passive side active.
If you need more events than you are already publishing, you just add a log. You can seed the log with a backfilled dump of synthesized events from the state before the log existed (e.g. dump out all the current ProfilePicture
s).
When you think of your event bus as a replicated log (e.g. by implementing it using Kafka), consumption of an event doesn't prevent arbitrarily many other consumers from coming along later (it's just incrementing your read-position in the log). So that allows for other consumers to come along and consume the log for doing their own remix. One of those consumers could be simply replicating the log to another datacenter (enabling that active-passive).
Note that once you allow services to maintain their own views of the important bits of data from other services, you are in practice doing Command Query Responsibility Segregation (CQRS); it's thus a good idea to familiarize yourself with CQRS patterns.
QUESTION
I have a toy app with a couple of tests that involve connecting to a real sql server database. The tests pass on my local machine. I want to get them to pass on Azure Devops. The entire purpose here is to get the tests of our real app running against a real database on ADO. I do not want to switch to an in-memory database.
The process I am envisioning is something like the following. But I am open to a different process if it can accomplish my purpose:
- Start a Docker container with sql server.
- Run my tests pointing at the database inside the container.
- Delete the container.
I have a hello-world yml script that starts up sql server. It is a shortened version of a script I found via How do I get MSSQL service container working in Azure DevOps pipeline? and published at https://developercommunity.visualstudio.com/content/problem/1159426/working-examples-using-service-container-of-sql-se.html. When I run it as a pipeline, it succeeds:

However I noticed that use use dotnet core. So please change your task to use dotnet command line tasks.
So you need to use
- dotnet restore

- dotnet test

host agents.

I have looked for an answer and all I can find are answers related to forms. I haven't seen anything related to a model object. I have a model called PanelType and I am trying to loop through every object to display relevant information pertaining to each panel type on a html template. I have created 3 PanelType objects through the admin page, so there is not "None". I believe I have this setup correctly but it's returning an error of returning None objects. I'd appreciate any help.

QUESTION
The mobile version of the home page slider looks very funny, it looks stretched and doesn't fit well. I have tried setting image height to auto then it becomes small and does not fit the width and height properly. Here is the link to the project. I have tried various adjustments and the mobile version of the picture and it looks stretched and funny compared to the desktop.Please check out the link and help out
...ANSWER
Answered 2020-Oct-11 at 16:32The p roblem is that the images are set to show at 100% height and 100% width. When the aspect ratio of the user's device (or window) is different from that of the image itself the image will get stretched one way or another.
As the user's viewport/window may be of any aspect ratio - you can't cater for absolutely every device out there let alone if the user shrinks the window on a desktop (which could end up with any aspect ratio) you need to think about showing just part of each image if necessary on the different aspect ratios.
One way of doing that is to use the object-fit spec in CSS. This will expand an image to cover the whole screen, but will avoid distortion by cropping either the left and right or the top and bottom as needed. If your images are chosen carefully, particularly if you center the images and make sure the central parts 'make sense' (e.g. aren't just blank) the site should still look OK.
I tried on your site adding object-fit: cover; to .home-page-slides img and your images looked OK on narrow (portrait) windows as well as landscape ones at all sorts of aspect ratios, but you probably want to make sure they are centred too.

I try to transfer my projects CI to GitHub Actions. For integration tests I need to start and access redis container. I am using info from this article. So code looks like this
...ANSWER
Answered 2020-Sep-01 at 16:52U need to host an external redis database because containers in GitHub Actions are isolated. For other hand u can prepare a docker container with all you need for testing and then u can run the tests inside.
Un can take a look here https://github.com/gonsandia/github-action-deploy Its a custom action where u define the dockerfile and the scripts to runs

QUESTION
In my github actions workflow I am getting this error (ECONNREFUSED) while running my jest test script. The test uses axios to connect to my api which is running in a container bootstrapped via docker-compose (created during the github workflow itself). That network has just has 2 containers: the api, and postgres. So my test script is, I am assume, on the "host network" (github workflow), but it couldn't reach the docker network via the containers' mapped ports.
- I then skipped jest test entirely and just tried to directly ping the containers. Didn't work.
- I then modified the workflow to inspect the default docker network that should have been created:
I've narrowed down the issue as follows. When I modified the compose file to rely on the default network (i no longer have a networks:
in my compose file):
So it looks as though the containers were never attached to the default bridge network.
UPDATE 2It looks like I just have the wrong paradigm. After reading this: https://help.github.com/en/actions/configuring-and-managing-workflows/about-service-containers
I realise this is not how GA expects us to instantiate containers at all. Looks like I should be using services:
nodes inside the workflow file, not using containers from my own docker-compose files. 🤔 Gonna try that...

Host NetworkSince you are using docker compose, when you start the api container, publish the endpoint that the api is listening on to the host machine. You can achieve this by doing:
