I'm using the Azure resource "Web app for containers" with a Linux docker image. I would like to use docker commands such as "docker inspect" but I'm not sure how this is possible. Via the Kudo interface this doesn't seem possible. I cannot even get the SHA256 hash of the image currently deployed. All I have is the initial docker run command executed by the app service itself.
Does anyone know how such operations can be executed with app containers in Azure ?
The Azure Web app for container is different from the container. It is a web app service when you create it. The difference is that it comes out from a container.
So you cannot execute a docker command to a web app. You can execute the command of the web app.
For example, if you want to check the container image, the command is az webapp config container show --resource-group groupName --name webName and the result like this:
For more details about Web app command, see Web App commands.

I have an Azure Container App with simple nodeJs api service. I need to read logs of this application, just to see my console.log('Hi there!').
Container App has Monitoring Logs with huge list of different queries. Which one I need to use to see my console? Or can some one provide a simple query to fetch my logs?
p.s. I want to see same logs which I can see with command:
az container logs show -n <containerName> -g <resource group>
I have tried to reproduce the issue by deploying a sample app and app service container in Azure.
To view our application console logs go to Revision Management-->click on your app-->select console logs(view details) as shown in below image:
After running the query above you can see the console logs which were generated by your application.
I have a Web app running on Linux which is deployed from Docker Container.
Container comes from Azure container registry and was defined when I created the web app.
When I try to set my release pipeline to deploy to this web app, it doesnt offer me this choice.
When I set my subscription and Web app on Linux, I only see web apps that are deployed from code. My web app from docker container is not in the list in the App Name select:
I tried to do this manually using Azure PowerShell. I have set up local connection and trying to test the deploy but it doesnt work.
I have downloaded the repository locally as a zip file and I am trying to deploy it from this local zip file to the Web app on Azure. I try to deploy it from Powershell:
$webapp = Get-AzWebApp -ResourceGroupName "MyResourceGroup" -Name "my-container-app"
$path = 'C:\temp\repository.zip'
Publish-AzWebApp -WebApp $webapp -ArchivePath $path -Force
I am using Publish-AzWebApp command.
This command goes without an error, I also tried without -Force parameter, and with -AsJob parameter.
Everytime the command is executed successfully, but when I check my web app there is nothing deployed there. If I try this exact procedure with web app that is not from container, but from code than it works. By code/container I mean this setting that you choose when creating web app:
Currently I am using docker image that is also used by Azure as default so it should be the same Debian. I need to use it because I want to set some things differently in my web app, so I want to have my own system on web app, but deploy code from Devops to it.
However it seems that this type of web app is not supperted for deploy - nether from Devops gui, nor from Azure CLI. Can I somehow deploy my code on a web app that is running on my custom docker image?
PS: One option is to use the agent in Devops pipeline, compile a docker image from it and publish it with my code to the Azure container repository, from which it can be used form my web app. Problem is that you can only choose from 2 Ubuntu versions as an agent for build pipeline and I dont want that.
Any help is appreciated, thanks
For your requirements, first of all, you need to know the Web App on Linux and Web App for Container are two different resources, so it does not list your app deployed from the docker image. And second, when you use the docker image, it means you need to create a new image when your code change. So it does not support that create the Web App from the docker image and then publish the code from the DevOps.
The option that you think is right. Don't worry about the OS, you can use the Azure CLI command to create the docker image and push it to the Azure Container Registry directly:
az acr build -t image_name:tag -r acr_name source_code_path
And then deploy the image from the ACR to the Web App. In this way, the DevOps agent just use to run the task, not for the creation of the docker image.
I am unable to run docker image dpage/pgadmin4 on azure web app (Linux) which is available on docker hub.
I have installed Docker in my Linux machine and was able to run that docker image locally. Then I created Web app in Azure with options as given below:
OS: Linux
Publish: Docker Image
App service plan: Linux app service
After creating web app, I added two env variables in App Settings section:
PGADMIN_DEFAULT_EMAIL : user#domain.com
PGADMIN_DEFAULT_PASSWORD : SuperSecret
Finally login screen is visible but when I enter above credentials, it doesn't work and keeps redirecting to login page.
Update: If login is working properly, screen appears as shown below.
!(pgadmin initial screen)
After several retries i once got an message (CSRF token invalid) displayed in the right-top corner of the login screen.
For CSRF to properly work there must be some serverside state? So I activated the "ARR affinity" in the "General Settings" on the azure "Configuration".
I also noticed in the explamples on documentation the two environment-variables PGADMIN_CONFIG_CONSOLE_LOG_LEVEL (which is in the example set to '10') and PGADMIN_CONFIG_ENHANCED_COOKIE_PROTECTION (which is in the example set to 'True').
After enabling "ARR" and setting PGADMIN_CONFIG_ENHANCED_COOKIE_PROTECTION to False the login started to work. I have no idea what PGADMIN_CONFIG_ENHANCED_COOKIE_PROTECTION is actually doing, so please take that with caution.
If thats not working for you, maybe setting PGADMIN_CONFIG_CONSOLE_LOG_LEVEL to 10 and enabling console debug logging can give you a clue whats happening.
For your issue, I do the test and find that it's really a strange thing. When I deploy the docker image dpage/pgadmin4 in Azure service Web App for Container through Azure CLI and set the app settings, there is no problem to log in with the user and password. But when I deploy it through the Azure portal, then I meet the same thing with you.
Not sure what is the reason, but the solution is that set the environment variables PGADMIN_DEFAULT_EMAIL and PGADMIN_DEFAULT_PASSWORD through the Azure CLI like below:
az webapp config appsettings set --resource-group <resource-group-name> --name <app-name> --settings PGADMIN_DEFAULT_EMAIL="user#domain.com" PGADMIN_DEFAULT_PASSWORD="SuperSecret"
If you really want to know the reason, then you can make feedback to Microsoft. Maybe it's a bug or some special settings.
Update
The screenshot of the test on my side here:
Am following node application deployment guide in Azure app service .After creating the web app in azure it asks to redirect to below url
https://<app_name>.scm.azurewebsites.net/ZipDeployUI
But after redirecting it says.
"No route registered for '/ZipDeployUI'
Any clue to fix this issue.
https://<app_name>.scm.azurewebsites.net/ZipDeployUI does not work for Linux App Services at this time. Consider using FTP or the ZIP deploy API instead.
Uploading the zip file through the cli.It worked fine for me
az webapp deployment source config-zip --resource-group myResourceGroup --name <app_name> --src clouddrive/<filename>.zip
You have few options. Don't worry about not having the zipDeploy endpoint. You can ssh file, you can upload from a CLI, and a few others options are also there. Please refer to the below documentation:
https://learn.microsoft.com/en-us/azure/app-service/deploy-zip
I got this error on a Linux App Services instance. According to the documentation for the ZipDeployUI endpoint:
The above endpoint does not work for Linux App Services at this time.
Consider using FTP or the ZIP deploy API instead.
Switching to a Windows App Services instance fixed the issue for me.
I have a container building in gitlab and registering itself with the gitlab custom registry. Inside this container is a command that runs a very long time. I would like to somehow deploy this container to azure, and only kick off this long running process inside a new container instance on demand from an administrative api service. I don't want the container running all the time, only for the time it takes to run the command.
I was thinking that this admin api could be a classic http rest api service hosted under Azure "App Services", or possibly using the new "Function Apps" feature of Azure.
In my research, I found that using the azure cli commands, I can start a container like so:
az container create \
--resource-group myResourceGroup \
--name mycontainer2 \
--image microsoft/aci-wordcount:latest \
--restart-policy OnFailure \
--environment-variables NumWords=5 MinLength=8
https://learn.microsoft.com/en-us/azure/container-instances/container-instances-environment-variables
I would like to do this from the admin api, preferably using what looks to me like the official Azure npm package located here:
https://www.npmjs.com/package/azure
Ideally, it would be a single command to create and start the instance, being able to set the environment variables like this example at the launch of the container is important to me. I'm not interested in moving all my code over into Azure, I would like to continue using gitlab for the source code and container registry but if there is some reason I have to switch to using the Azure container registry, I need a way to somehow move the container registration over there using the gitlab ci yaml.
In all my searching, I couldn't find any way to do this but the closest documentation I found was here:
https://learn.microsoft.com/en-us/javascript/api/azure-arm-containerservice/containerserviceclient?view=azure-node-latest
At the current time there is no way to officially do this from the api, maybe in the future there will be
