failed to fetch anonymous token docker

After this step, most of the official documentations asks you to deploy a sample YAML to test if you can fetch the image from ACR. Finally, I ended up opening up these URLs in the firewall to be able to fetch images, which were imported from sitecore registry. In summary, focus on these: Anupam Shrivastava, a learner, explorer, traveler and tech enthusiast. But I am mentioning it here because this was one of the troubleshooting steps. Apparently, in a production environment, there are multiple parameters, all of which need to work well in order to this solution to work which look so simple in first glans, otherwise, you could end up spending hours, even days, troubleshooting what went wrong. You need permission on Azure AD to be able to execute this script successfully. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Your email address will not be published. https://github.com/joseph-jclab/open-vm-tools-builder/blob/e49844400fd0d01bbf8fcb9fad956185927230d3/.github/workflows/build.yaml, https://github.com/joseph-jclab/open-vm-tools-builder/runs/2680858043?check_suite_focus=true. I deleted and recreated the Image Pull Secret multiple times, putting the values in no quotes, single quotes, double quotes, nothing worked. Since I was getting 401 unauthorized error, I thought maybe I should try to get the image from ACR without using Image pull secret first, just to isolate that the problem was indeed with image pull secret itself.

So, AKS was unable to reach registry-1.docker.io, must be Azure firewall. If everything goes well, you will receive a one liner output like secret created. Finally, this is how my application rule contained, before I could see the image getting pulled successfully by AKS. But this article is NOT about Sitecore in general, its about how can we make use of Image Pull Secrets to pull images stored in a private container registry, ACR in my case. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. So, it wa time to move on and focus on getting the image fetched using Image pull secret again.

But this time too, I was greeted with this nice error message. I kept trying and adding the host names it was trying to access in the Azure Firewall Allow rules. We need to get these 2 points right. So, based on my learnings, I decided to put down a few points which might help others avoid some of those troubles. Just google for Imagepullsecret not working or Imagepullsecret throwing access deined etc. This can easily be overlooked, so if you passing the namespace name as sitecore-sit in the Image pull secret, ensure that the YAML file also contains the exactly same namespace. As the official documentations explain we first need to create a Service Principal in Azure AD and give it at least acrPull permission in the ACR.

By clicking Sign up for GitHub, you agree to our terms of service and This topic may seem a bit outdated as there are better (and more recommended) ways now to work with Azure Container Registry (ACR). Since accessing Images from such public registry doesnt need Image Pull Secret. It seems to me like docker compose fetches images differently than docker pull, failed to authorize: rpc error: code = Unknown desc = failed to fetch anonymous token (Bad Request). We only tested with Linux. So, I added an Application Rule there to allow access to *registry-1.docker.io. When I found that My AKS was unable to pull images from my ACR. We never tested with Win or Mac. You can check this quickly with. Use same Kubernetes version in Client and Server, Create Image Pull Secret in the same Namespace where you are deploying your Pod. And our environment is complete with VNET, Application Gateway, Azure Firewall, AKS etc, so it resembles a proper staging/production environment and not a POC setup. to i.mar@gmail.com, Google Cloud Endpoints, https://www.googleapis.com/auth/service.management.readonly, local@gl-beefastdelivery-dev.iam.gserviceaccount.com, https://servicecontrol.googleapis.com/v1/services/ENDPOINTS_SERVICE_NAME:report, https://groups.google.com/d/msgid/google-cloud-endpoints/06a2ca49-eb46-4b29-b580-6f5591ac4014%40googlegroups.com, google-cloud-endpoints+unsub@googlegroups.com, https://groups.google.com/d/msgid/google-cloud-endpoints/8736d7c3-56db-4e88-86e3-a542bd4aec76%40googlegroups.com. And this time . So, the idea is simple, when we deploy a Pod in say staging AKS environment, it references to the ACR and pulls the image using ImagePullSecret directive in YAML file. And tried to deploy the YAML again. I tested the YAML deployment after each additional rule, and surely, it was still blocking others. If these two wont match, Image Pull Secret will still get created without any complaints, but wont be able to fetch images. This one is easy just connect to your AKS instance and run this command. And after these settings, finally when Ii deployed the YAML, saw that status Running. Fresh with the first success, I cross verified that ACR is added as allowed in Azure Firewall using the Service Tag and imported an image in my ACR and tried to pull the image from ACR this time, using Image Pull Secret.

Like this example from official documentation. I don't know why. So, I changed the image URL to point to a docker and executed the YAML. privacy statement. to your account, workflow : https://github.com/joseph-jclab/open-vm-tools-builder/blob/e49844400fd0d01bbf8fcb9fad956185927230d3/.github/workflows/build.yaml, log : https://github.com/joseph-jclab/open-vm-tools-builder/runs/2680858043?check_suite_focus=true. so maybe the c++ code could not open the file but Python code could with your path.

So, why this article in the first place? We tent to keep our client up to date whereas server is running some other version. Also, I was opening it in nodepad++ at times, so to indent, use space button, not tabs! So, like I did with the public docker images, I started to add allow rules for each of those URLs, one by one. Your AKS Kubernetes Server version and Kubectl client version must match: This is so easy to get it wrong. Have a question about this project? Essentially, we created one common ACR which will be shared by all AKS environments like SIT, Staging and Production. But to keep any firewall related issues out for the time being, I also added another (*) rule to allow all traffic. Image Pull Secret tag MUST be at the same level as of containers and first level inside spec. So, I removed the rule and tried to pull the image again and surprise surprise, I received a similar error. And the culprit this time, a little formatting error in the YAML. Lets first start with the known steps. What a relief! Thank you Anupam really helpful level of detail.

I was able to get the images with Docker pull -u -p , so the service principal surely has the required permissions to pull the image. Already on GitHub? Well, depends! or Win. I am experiencing the same error, but not when I directly docker pull . Check your Azure Firewall Logs to examine which requests are getting blocked when the Pod is getting deployed and add them to allow rules. So, get the idea. And to my surprise, even though, I was trying to pull an image which I imported in my ACR, when AKS was trying to pull the image after deploying YAML file, it was trying to refer to lot many more URLs which were getting blocked by the firewall. Now this is a bit off topic. What flags did youpass to ESP in your "docker run"? We can use the following script to create a Service Principal. As you can Imagine, I suspected something to do with the Image Pull Secret created earlier. I wont bore you with more details of the troubleshooting, but rather the final outcome about this. You said you run in Mac. Now it was time to remove the (*) rule from Azure Firewall. Sitecore has been busy updating their documentation related to installation and configuration on Azure Kubernetes Services (AKS) and has published a great installation guide. So, I executed this command, since my ACR and AKS are in two different subscriptions: Deployed the YAML again, and guess what, I received the same 401 unauthorized error. My first step of troubleshooting was to isolate the problem, whether there was something wrong with AKS or ACR. Power of Power Automate and a Big Limitation! I was sure that this has nothing to do with Authentication or Authorization anymore.
