Azure Container instances
This is the first time i use docker image
when i trying build and upload new version code and push in Azure Container registries
but if i want to apply new version code , i must restart Container instances by manual to apply new version code , it annoys me and is a waste of time
How to resolove auto restart or redeploy when i push new version code in Container registries in Azure ?
this is log deploy azure of myself
I can think of a couple of ways to do this.
AKR Webhooks
I probably will approach this by looking at the webhooks in AKR.
Then, create a Logic App to receive the webhook call when a new image is pushed. References.
In the Logic App, you can call one of the Azure Container Instance APIs to restart the container group.
You will need to consider the security of the Logic App, which can only be called by your AKR's webhook.
CI/CD Pipelines
Assume that you have used a CI/CD platform like Azure DevOps, where you can create build pipelines.
The pipeline can build and push the images to your AKR, then create a step to run Az command to update the instance group.
I probably prefer the pipeline approach as I can see the history of what images have been released on the DevOps page.

I have a pipeline that publishes to my private Azure container registry but if I push a new image tagged with latest, my Azure app service does not pull the newly tagged latest image. I have Continuous deployment turned on via the DOCKER_ENABLE_CI app setting.
Additionally, I'm using a managed identity to authenticate with the ACR. I feel like the CD portion was working when I was using credentials to pull the image but after switching to managed identity it appears to have stopped. In order to get the new image I have to restart the app service which is not idea and makes this CD option useless...
When you enable Continuous deployment, App Service adds a webhook to your ACR to notify the web apps. The webhook causes your App Service app to restart and run the docker pull to get the updated image.
So, please go to your ACR, and under webhook, please check if there are running webhooks or not, if not you can create a webhook manually and see if the WebApp get the latest image in the following deployment.

I'm currently using resource: container in azure pipeline to pull my custom image tools from ACR, and use this image to create a container than can run several CLI commands on my pipeline.
Pulling this custom image tools takes so much time, roughly around 5mins and I want to avoid that as it is considered as a wasted time and a blockage since I do debugging most of the time.
Question: Is it possible to create an Azure Container Instance that constantly run my custom image tools then call this container inside my pipeline to run some cli commands?
I'm having a hard time finding documentation, so I'm not really sure if it is possible.
You can try to set up a self-hosted agent in your custom Docker image, and when running the container on ACI, it will install the agent and connect it to your Azure DevOps.
Then, you can use this self-hosted agent to run your pipeline job which needs to run the CLI commands. Since the self-hosted agent is hosted in the container, the job runs on the self-hosted agent will run in the container.
About how to configure set up self-hosted agent in Docker image, you can reference the document "Run a self-hosted agent in Docker".
I have a containerized app's image that builds on master push and ends up in azure container registry. I need to setup the next step where this image ends up on my linux on prem server.
I have established the connection with the server using a deployment group agent, which claims is healthy.
I have created a pipeline which takes the built image artifact as input but I am completely failing to grasp and create the step in which the artifact is being pulled on / pushed to the server (and ideally run too).
I am looking at the tasks in the pipelines > task section in Azure Devops but I cannot find a place to add some specific steps neither I am very sure what steps to add.
I would very much appreciate any tip on how to deploy a container from acr to on premises linux server using azure devops pipelines. Thank you in advance.

I have created an application by using azure's kubernates service.
In my yaml I specified "latest" as image version for every image I'm using.
Is there any option to make so that, when I update the image registry so that "latest" changes, kubernates auto-deploys that? And everything is managed so that it only updates one replica and then scales so that service is not interrupted during deploy?

It's not kubernetes's work to handle this. There are two steep to work on this:
Add webhook on docker registry, for docker-hub, it is Docker Hub Webhooks. When new image has been pushed to registry, you can send a POST request to somewhere as notification.
Deploy a CI/CD to receive that notification and roll update your application. Or just create a simple HTTP Server to handle notification request and do something like kubectl ....
And everything is managed so that it only updates one replica and then scales so that service is not interrupted during deploy?
Kubernetes handle this by rolling update. For Deployment or StatefulSet, current kubernetes auto update pods by rolling update, all you need to do is kubectl apply -f new-spec.yaml.
Kubernetes is not aware of the changes at your registry, it is not monitoring for new container images. You would need to create a process that is triggered when a new version is released and updates your Kubernetes deployment. You could use CI/CD tools for this, or things like Azure Functions, Azure Automation etc.
For deploying without downtime you would want to look at rolling updates.
you should really use release management for this or something like gitops that would trigger updates when new version of container is available. using Azure Functions\Automation for this is just not right. Its not meant for that, it would be complicated\unreliable.
Let's assume that we have 3 different container registries. Is there any available azure devops jobs/tasks that can provide a way to trigger my build pipeline when a new image is pushed on any of these 3 registries?
I have some insights with MS Flow but i want to limit the scope on azure devops.
Find a way or recommendation to trigger the build pipeline using devops jobs/tasks.
You can create in Azure Container Registry a web hook that trigger the build in Azure DevOps when new image pushed.
For this you need to write a service with Web API that handle the API Post calls. the ACR web hook send a Post call to the service when new image is pushed.
In the service you trigger the Azure DevOps build pipeline using the Azure DevOps .Net Libraries (if the service is in C#) or with Azure DevOps Rest API.
How to create ACR Web Hook? find here.
How to trigger build pipeline from code? find here.
you can have releases triggered with new images in the docker hub (reading). I dont think the same can be done for builds. You can create a release that would get triggered on the new image and that release would talk to the API to trigger the build.
