failed to fetch anonymous token docker

What a relief! I wont bore you with more details of the troubleshooting, but rather the final outcome about this. Power of Power Automate and a Big Limitation! Well occasionally send you account related emails. You need permission on Azure AD to be able to execute this script successfully. This topic may seem a bit outdated as there are better (and more recommended) ways now to work with Azure Container Registry (ACR). Now that Image Pull Secret is in the format we want, I was still unable to fetch the image from ACR.

By clicking Sign up for GitHub, you agree to our terms of service and If these two wont match, Image Pull Secret will still get created without any complaints, but wont be able to fetch images. I have these roles on the service account: ESP has two places to generate acces_token from service account file. At this time, I was able to pull the image successfully from my ACR Yay! Finally, this is how my application rule contained, before I could see the image getting pulled successfully by AKS. Hmm, but from the error code, it seems that you did not pass service account file to ESP. Lets first start with the known steps. Use same Kubernetes version in Client and Server, Create Image Pull Secret in the same Namespace where you are deploying your Pod. and you will find numerous discussion thread going on for years. With Sitecore now supporting Container based installations, many organizations are choosing to go that way to be future proof. If you are in luck, you will see that AKS was able to fetch your image from ACR and the pod as running, but it can also be that you receive one of the many possible errors. Please make sure it has following role. Now it was time to remove the (*) rule from Azure Firewall. As the whole idea of this article was to pull the images using Image Pull Secret. Essentially, we created one common ACR which will be shared by all AKS environments like SIT, Staging and Production. Note down the Service principal ID and Service principal password shown in the output, well make use of those to create the Image Pull Secret. So, based on my learnings, I decided to put down a few points which might help others avoid some of those troubles. What can go wrong, right? 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. privacy statement. It took me quite sometime to figure it out, so I wanted to pen these down to save same efforts and anxious hours spent on troubleshooting. But I am mentioning it here because this was one of the troubleshooting steps. 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. We can use the following script to create a Service Principal. This one is easy just connect to your AKS instance and run this command. Your email address will not be published. As you can Imagine, I suspected something to do with the Image Pull Secret created earlier. And this is how my Application Rule Collection look like. So, I added an Application Rule there to allow access to *registry-1.docker.io. I kept trying and adding the host names it was trying to access in the Azure Firewall Allow rules. Sign in I am experiencing the same error, but not when I directly docker pull . Finally, I ended up opening up these URLs in the firewall to be able to fetch images, which were imported from sitecore registry. 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. I don't know why. Thank you Anupam really helpful level of detail. Now this is a bit off topic. Just google for Imagepullsecret not working or Imagepullsecret throwing access deined etc. 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. You said you run in Mac. If you google, about this topic, there are numerous articles, really good ones too with step by guide, like this one from Microsoft. Lets summarize what we are trying to achieve here We have an image stored in our Azure Container Registry, which resides in a Resource Group in a separate subscription than where our AKS is. When I found that My AKS was unable to pull images from my ACR. So, lets try to make the world better for our fellow cloudizens :). Check your Azure Firewall Logs to examine which requests are getting blocked when the Pod is getting deployed and add them to allow rules. But well, this time, I was greeted with something new: So, it looked like that was able to reach ACR but couldnt authenticate successfully. or Win. So, I changed the image URL to point to a docker and executed the YAML. But this time too, I was greeted with this nice error message. 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. Have a question about this project? But to keep any firewall related issues out for the time being, I also added another (*) rule to allow all traffic. New technologies drive me and cloud is where we live now. You do not have permission to delete messages in this group, Either email addresses are anonymous for this group or you need the view member email addresses permission to view the original message, INFO:Constructing an access token with scope, INFO:Fetching the service config ID from the rollouts service, INFO:Fetching the service configuration from the service management service, nginx: [warn] Using trusted CA certificates file: /etc/nginx/trusted-ca-certificates.crt, 2019/09/12 19:57:26 [error] 10#10: connect() failed (111: Connection refused), 172.17.0.1 - - [12/Sep/2019:19:57:26 +0000] "GET /v1/deliveryRequest HTTP/1.1" 500 209 "-" "PostmanRuntime/7.16.3", 172.17.0.1 - - [12/Sep/2019:19:57:27 +0000] "GET /v1/deliveryRequest HTTP/1.1" 500 209 "-" "PostmanRuntime/7.16.3", 2019/09/12 19:57:28[error]10#10: Failed to call, [libprotobuf ERROR external/servicecontrol_client_git/src/service_control_client_impl.cc:182] Failed in Report call: Service control request failed with HTTP response code 403, It seems that the service account doesnthave enough roles to call service control services. So, AKS was unable to reach registry-1.docker.io, must be Azure firewall. The text was updated successfully, but these errors were encountered: Looks like this is an issue with your self-hosted runner. Image Pull Secret tag MUST be at the same level as of containers and first level inside spec. We never tested with Win or Mac. We tent to keep our client up to date whereas server is running some other version. 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. We only tested with Linux. In my case, it was the later case and I ran into ImagePullErr and ImagePullBackoff and many more. I was sure that this has nothing to do with Authentication or Authorization anymore. You signed in with another tab or window. Well, the answer the simple. However, there are still many popular products in market, Sitecore in my case, which still use Image Pull Secret as the primary way to pull images from ACR. Even though, officially, we can keep Client and Server versions different by one minor versions, I recommend to use the exact same version for both. 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. As just putting an allow all rule in firewall makes it work. 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. If everything goes well, you will receive a one liner output like secret created. And after these settings, finally when Ii deployed the YAML, saw that status Running. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Your email address will not be published. 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. And the culprit this time, a little formatting error in the YAML. Already on GitHub? Your AKS Kubernetes Server version and Kubectl client version must match: This is so easy to get it wrong. so maybe the c++ code could not open the file but Python code could with your path. Also, I was opening it in nodepad++ at times, so to indent, use space button, not tabs! 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. Like this example from official documentation. of-course, your URLs will be different depending upon your images. So, let me walk you through with some of those, so that you can avoid some sleepless nights due to such errors. In summary, focus on these: Anupam Shrivastava, a learner, explorer, traveler and tech enthusiast. So, get the idea. Required fields are marked *. You should create your ImagePullSecret in the same Namespace in which you are deploying your Pod. 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 removed the rule and tried to pull the image again and surprise surprise, I received a similar error. And this time . 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. So, like I did with the public docker images, I started to add allow rules for each of those URLs, one by one. 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. Guess you are behind a corporate proxy. I tested the YAML deployment after each additional rule, and surely, it was still blocking others. Well, depends! So, it wa time to move on and focus on getting the image fetched using Image pull secret again. 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). So, I enabled Diagnostic logging for the Firewall and started to monitor the deny traffic. Now, this was frustrating! What flags did youpass to ESP in your "docker run"? Should be able to access docker hub anonymously. So, why this article in the first place? You can check this quickly with. 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. 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. 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. Works fine on my side with GitHub runners (ubuntu-latest). And tried to deploy the YAML again. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Since accessing Images from such public registry doesnt need Image Pull Secret. I deleted and recreated the Image Pull Secret multiple times, putting the values in no quotes, single quotes, double quotes, nothing worked. My first step of troubleshooting was to isolate the problem, whether there was something wrong with AKS or ACR. We need to get these 2 points right.
