in a current project I have a problem understanding (and configuring) routing within my vue.js app.
Our Setup
We have a setup, where for each Pull Request in our repos a new Snapshot Environment is created. This environment is one namespace within a kubernetes Cluster. All services in a current develop state are deployed with the new "snapshot" version of the service that triggered the CICD pipeline. To have a clear route for each snapshot environment, we use the namespace as part of the URL (https://HOST/NAMESPACE/APP/paths)
Our Problem
As you can see, the URL is highly dynamic, but currently, we could just build the container with the path and be happy. Thats our current setup. Unfortunately, we want the possibility, to deploy each and every container image on every HOST as well as every NAMESPACE, those parts are only known at runtime, not in the CICD Pipeline.
Is there any way to handle such a scenario with vue.js. I have basically every freedom to edit the app as well as the container, but can't change the way we want to host our app. Currently we build the App on the cluster and inject the NAMESPACE, which was the "easiest" way to do this. But if there is any other way, I would love to not have the build and run step together.
Thanks in advance.

We have multiple repositories that have multiple deployments in K8S.
Today, we have Tekton with the following setup:
We have 3 different projects, that should be build the same and deploy (they are just different repo and different name)
We defined 3 Tasks: Build Image, Deploy to S3, and Deploy to K8S cluster.
We defined 1 Pipeline that accepts parameters from the PipelineRun.
Our problem is that we want to get Webhooks externally from GitHub and to run the appropriate Pipeline automatically without the need to run it with params.
In addition, we want to be able to have the PipelineRun with default paramaters, so Users can invoke deployments automatically.
So - is our configuration and setup seems ok? Should we do something differently?

This sounds ok. The GitHub webhook initiates PipelineRuns of your Pipeline through a Trigger. But your Pipeline can also be initiated by the users directly in the cluster, or by using the Tekton Dashboard.
I'm currently developing a simple webapp with seperated frontend (Vue) and backend (quarkus REST API) project. For now, I've setup a MVP, where the frontend is displaying some simple data which is called from the backend. To get a working MVP i need to setup CORS support. However, first i want to explain my setup:
Setup
I'm starting developing environment of my frontend with npm run serve and of my backend with ./mvnw quarkus:dev. Frontend is running on localhost:8081 and backend running on localhost:8080.
Heroku allows to run your apps locally aswell with the command heroku local web. Frontend is running on port 0.0.0.0:5001 and backend on 0.0.0.0:5000.
To achieve this setup i setup two .env files on my frontend which are pointing to my backend api. If i want to work in development mode the file .env.development is loaded:
VUE_APP_ROOT_API=http://localhost:8080
and if i run heroku local web the file .env.local with
VUE_APP_ROOT_API=0.0.0.0:5000
is loaded.
In my backend I've set
quarkus.http.cors=true
in my application.properties.
Now I want to deploy those two projects to heroku and use it in production. Therefore I setup two heroku projects and set a config variable in my frontend project with the following value:
VUE_APP_ROOT_API:https://mybackend.herokuapp.com
Calls from my frontend are successfully working!
Question
For the next step, I want to restrict it more and just enable my frontend to call my API. I know i can set something like
quarkus.http.cors.origins=myfrontend.herokuapp.com
However, I dont know how i could do this on quarkus with different environments (development, local and production)? I've found this link but I don't know how to configure heroku and my backend app correctly. Do i need to setup different profiles which are applied on my different environments? Or is there another solution? Do i need Herokus Config Variables?
Thanks for the help so far!
quarkus.http.cors.origins is overridable at runtime so you have several possibilities.
You could use a profile and have everything set up in your application.properties with %prod.quarkus.http.cors.origins=.... Then you either use -Dquarkus.profile=prod when launching your application or you use QUARKUS_PROFILE=prod as an environment variable.
Another option is to use an environment variable for quarkus.http.cors.origins. That would be QUARKUS_HTTP_CORS_ORIGINS=....
My recommendation would be to use a profile. That way you can safely check that all your configuration is consistent at a glance.
First of all, sorry if this thread is not appropiated in Stack Overflow, but I think that is the best place of all.
We are using Rancher to manage a microservices solution. Most of the containers are NodeJS + Express apps, but there are others like Mongo or Identity Server.
We use many environment variables like endpoints or environment constants and, when we upgrade some of the containers individually, we forget to include them (most of the times, the person who deploys an upgrade is not the person who made the new version).
So, we're looking a way to manage them. We know that using a Dockerfile could be the best way, but if we need to upgrade just one container, we think that is too many work for just a minor change.
TLDR; How do you manage your enviromental variables in Rancher? How do you document them or how you extract them automatically?
Thanks!
Applications in Rancher are generally managed using Stacks/Services. Dockerfile is used to build a container image. docker-compose/rancher-compose files are used to define the applications. The environment variables can be specified in docker-compose file.
When you upgrade a service in rancher, the environment variables information is carried forward and also it's possible to edit them before upgrade.
Also Rancher "Catalog" feature might be something useful for you. Checkout: https://rancher.com/docs/rancher/v1.6/en/catalog/
I am using a GitLab docker image for integration testing of a service I'm helping to develop. Ideally, the image would be a preconfigured snapshot of GitLab with different users and repos available to run tests against. So the problem ends up being, what is a good way to automate the creation of 'snapshots' of GitLab (that can then be versioned etc.)?
My current solution to this problem is to use GitLab's built in backup utility via gitlab-rake gitlab:backup:create after getting GitLab to a state that I want. This then lets me use GitLab's gitlab-rake gitlab:backup:restore in a hook when the container is starting up to get the container back to the state that I expect (the backup having been ADDed in the Dockerfile for the image). This has the advantage of being relatively lightweight (backups are on the order of MBs) and the backups can be checked in to version control.
I have tried using docker export along with docker import to save the state of the container and then create an image based on that state. This has the advantage of being easy to automate since it is directly supported by Docker, but ends up being fairly expensive considering what the goal is (having users and repos available to test against). It also would require the images to be pushed to a registry of some kind in order to be easily distributed. Perhaps this is the best solution because it is well supported though.
I suppose my question is, what is the Docker way of approaching a problem like this?
Currently I am using ms-deploy to build and deploy on several machines using team-city. In my current scenario, I need to build, package and deploy on Dev. After this I need to deploy this package on test and Live servers (which are on different domain. I understand how we do it but problem is Web transformation only occurs for test and live configs if we build a package. It means if I want to use the same package that is created for Dev cannot be used, as web transformation only occurred for Dev web config. Also know that we can change web config when un-packaging but that parameters are very limited. We have a lot of changes not just the connection string or db changes.
Another solution is to add another step to build packages for test and live as part of Dev deployment but then it means a lot of copying on remote servers, once for test and once for live which is a lot of time consuming due to different domains.
Can you please guide what is the best solution in this scenario. So I can use team-city to publish to Dev and test and live using same package and different web configs in one go.
To configure items at deployment time which are not automatically created for you. You can add a file named parameters.xml to your project and extend what you want to make available at deployment time.
Here's some documentation on the approach Using Deployment Parameters for Web.Config File Settings.
