I am working on a new webapp in azure cloud.
The challenge is that I am working on a new python module that I dont know that well, Pyspice. Pyspice interface to a program Ngpspice.
On my windows PC it works fine but not on the cloud. So I would like to be able to do debugging without pushing and then wait 25min for each build.
Right now I am using SSH to connect to the webapp. Then I can create a simple python script to see if I can get the connection to work between pyspice and ngspice. The challenge I have is that when I run python in SSH then it uses a different environment than the webapp, i.e. all the modules in the requirements.txt is not available. So how can I change environment to be able to debug?
I have created an Azure App service with Python version 3.8, when I check the version in Azure SSH it is showing me different version.
To install the latest version in Azure SSH, run the below command
apt update
apt install python3.9
python --version
Run the below command to change the python version of the Azure App service in Azure Cloud Shell (Bash).
az webapp config set --resource-group MyRGName --name WebAppName --linux-fx-version "PYTHON|3.9"
To check the updated version, run the below command
az webapp config show --resource-group MyRGName --name Python4Nov --query linuxFxVersion
debug azure webapp using ssh
To remote debug Azure Linux App Service, we need to open a TCP Tunnel from the development machine to Azure App Service.
Configure for SSH and Remote Debugging
In Azure CLI run the below command
az webapp create-remote-connection --resource-group MyRG -n WebAppName

I'm running Docker Desktop 3.6.0 on Windows 10 with WSL2.
When I try to enable Kubernetes I only see "Failed to start" within the Docker Desktop UI.
Docker itself works fine. Not sure how I can get any further logs.
Here the output from kubectl version:
kubectl version
Client Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.3", GitCommit:"ca643a4d1f7bfe34773c74f79527be4afd95bf39", GitTreeState:"clean", BuildDate:"2021-07-15T21:04:39Z", GoVersion:"go1.16.6", Compiler:"gc", Platform:"windows/amd64"}

From other posts it seems that and internet connections is required for initial setup:

Direct internet connection is not possible on my work environment, I can only manually copy required images on my pc.
I also do not have admin access.
Is there a way to manually setup Kubernetes on Docker Desktop or somehow indicate where the required images can be found?
I have a nexus Docker repository where I can push required images to.
I have changed the ~\.docker\daemon.json and added my docker repository in insecure-registries. After first login docker is able to pull images from there and run them.
Already tried to reset or enable and disable Kubernetes. Also deleting ~/.kube/config did not work.
High level answer...
Get a docker registry
If you work for an old skool cool enterprise; use JFrog Artifactory
If you just want to get it to work; use Harbor
GitHub and GitLab (depending on license) have registries available too...
Edit the docker daemon on the kubernetes nodes (your workstation) to only pull from these registries.
if redhat; /etc/containers/registries.conf
if debain; /etc/docker/daemon.json
you might be able to hack a /etc/hosts entry too...
Populate the new registry
Run kubernetes and yoiu should be good to go. Depending on the configuration you choose you may need to add a registry credential secret.
I'm having a .Net Framework and .NetCore Containers and I would like to run them in Kubernetes. I have Docker Desktop for Windows installed and Kubernetes with it. How can I run these Windows Containers in Kubernetes?
This Documentation specifies how to create a Windows Node on Kubernetes, but it is very confusing. As I am on windows machine and I see linux based commands in there (And no mention of what OS you need to run all those). I am on Windows 10 Pro Machine. Is there a way to run these containers on Kubernetes?
When I try to create a Pod with Windows Containers, it fails with the following error message "Failed to pull image 'imagename'; rpc error: code = Unknown desc = image operating system 'windows' cannot be used on this platform"
Welcome on StackOverflow Srinath
To my knowledge you can't run Windows Containers on local version of Kubernetes at this moment. When you enable Kubernetes option in your Docker Desktop for Windows installation, the Kubernetes cluster is simply run inside Linux VM (with its own Docker Runtime for Linux containers only) on Hyper-V hypervisor.
The other solution for you is to use for instance a managed version of Kubernetes with Windows nodes from any of popular cloud providers. I think relatively easy to start is Azure (if you don't have an Azure subscription, create a free trial account, valid for 12 months).
I would suggest you to use an old way to run Kubernetes on Azure, a service called Azure Container Service aka ACS, for one reason, it has been verified by me to be working well with Windows Containers, especially for testing purposes (I could not achieve the same with its successor, called AKS):
Run following commands in Azure Cloud Shell, and your cluster will be ready to use in few minutes.
az group create --name azEvalRG --location eastus
az acs create -g azEvalRG -n k8s-based-win -d k8s-based-win --windows --agent-count 1 -u azureuser --admin-password 'YourSecretPwd1234$' -t kubernetes --location eastus
After Running this command on Azure Cli:
az vm extension set --publisher Microsoft.Compute --version 1.8 --name CustomScriptExtension --vm-name avmUat --resource-group argUat --settings '{"commandToExecute":"powershell.exe Install-WindowsFeature -Name Web-Server"}'
I get this error
Deployment failed. Correlation ID:
8d6972da-6d46-42e8-a053-f8e899348893. VM has reported a failure when
processing extension 'CustomScriptExtension'. Error message: "Invalid

Edit:
The result when I run it in powershell on Azure Cloud Shell:
Bash and this is on bash (Gladly it worked)
It seems that these commands do not work in the Azure CLI locally on the windows command prompt. You should run these on a bash environment.
With the same Azure CLI version. The same commands could work in Azure cloud Shell but not local Azure CLI in command prompt. I also tried running it on local Azure CLI 2.0.58, still failure.
Moreover, Here is the same Sample script, which is running in a bash environment.
Run this on my local command prompt.
Run it on Azure Cloud Shell
I'm using a Kubernetes cluster in Azure running an ingress controller. The ingress controller routes to different services via a given context root.
To add another service and connect it to my ingress I build a simple shell script looking like this:
kubectl apply -f $1'-svc.yaml'
some script magic here to add a new route in the hello-world-ingress.json
kubectl apply -f 'hello-world-ingress.json'
I tested the script on my local machine and everything works as expected. Now I want to trigger the script with an HTTP rest call on Azure.
Does anyone have an idea how to do that? So far I know:
I need the Azure cli with Kubernetes to run the kubectl command
I need something to build the HTTP trigger. I tried using AzureFunctions, but I wasn't able to install the Azure cli in Azure Functions on the Azure Portal and I wasn't able to install Azure cli + Azure Functions in a Docker Container.
Does anyone have an idea how to trigger my shell script via HTTP in Azure in an environment where the Azure cli exists?
The easiest way, in my opinion, is to set up an Azure instance with kubectl and the Azure cli configured to talk to your cluster and on that same server setup something like shell2http. For example:
shell2http -export-all-vars /mybash "yourbash.sh"
shell2http -form /apply "kubectl apply -f $v'-svc.yaml'"
shell2http -export-all-vars /domore "domore.sh"
Where $v above is the name of your deployment.
I am trying to install an ArangoDB cluster on google cloud. I run the install script. At every try I run up against and issue with an SSH onto the server. In the script there is an SSH user "core" and the script is looking for a password for this user to do SSH onto the server to set it up. I have no idea what that could be and have searched everywhere.
I am running the script from my local machine using gcloud SDK.
Any thoughts welcome!
