Authentication of Applications with Azure Active Directory
Access to the Azure Portal Architecture This high-level diagram shows the resources that will be created in Azure. The two nodes will be placed on their own vNet in a single subnet. These will be fronted by an Azure Load Balancer. In the portal, click on the Azure Cloud Shell button in the top right hand corner. You need a rule for port 80 and a rule for port to distrubute the load for Rancher server across our two VMs.
First lets create a variable for the name of the database server. This will make running the subsequent commands easier. If its not you will get and error when creating. If the name was not unique then an error will be displayed. If it is then update the variable with a new name and run this command again.
Sql" Add vnet rule to database access. Connect to the new MySQL server. This will deploy Docker, add the ubuntu user to the docker group and install k3s. It may take a short time to deploy Docker and K3s. Output the contents to the screen with the command below and copy this to your clipboard. You can use a xip. See the screenshot below. First, disconnet from node1. Now create the new directory and edit the file. Paste in the updated contents. Kubectl and Helm are installed in the Azure Cloud Shell.
Install the CustomResourceDefinition resources separately. Ensure you set the host name with the URL of you Rancher server. In this article, we are taking advantage of the xip.
By using K3s, not only have we been able to get up and running extremely quickly, we also have been able to remove etcd and some of the headaches associated with running it in production. By using the Azure Cloud Shell, authentication was easy and all of the tools we needed were available out of the box. Read our free white paper: How to Build a Kubernetes Strategy.
Creating application registration in Azure Active Directory The first step is to create an application registration in Azure Active Directory. To do this, first access Azure Active Directory, then click on App registrations and then New application registration. The application used in this configuration was configured in a common virtual machine with Linux, and the URL is the access for this restricted application.
After creation, the following result will appear: Click the name of the application, and on the next screen, click on Keys. Now, we need to define the name and the duration of key expiration. After this is filled in, click Save and copy the key shown in the Value field. I recommend that you save the information in a secure place, because we will use this in the next steps of this configuration.
To complete this Azure configuration, we need to add the allowed users who can access our application. But in the new Azure portal, it is not possible to add users. Authorization of users Now, in the old portal, click on Active Directory, and click on your directory. Next, click on Applications, and then on your application info created at the beginning of this article. To finish, click on Users. Select the users that will have access to the application and click Assign in the bottom menu bar.
To do this, create a oauth2proxy. You can get the Application ID inside the application properties. Client-secret is the key created.
The upstream is the address and port from where your application is running. Now, if you try to access the URL app, you will see the authentication page. When you click the sign-in button, you will be redirected to the Azure authentication page to log in and authorize access if you are not logged in.
If you are already logged in, you will be redirected to the application page. Software Engineer with experience in analysis and development of systems. Free software enthusiast and apprentice of new tech. Previous Article.

Because the cluster is RBAC-enabled, we need a cluster account and a role binding as well. The following tasks take care of all that: - task: KubectlInstaller 0 inputs: kubectlVersion: '1.
Deploy AKS and Traefik with an Azure DevOps YAML pipeline
We use the —admin flag to gain full access. Note that this downloads sensitive information to the build agent temporarily. The last task just runs a shell script to configure the service account and role binding and install tiller.
Check the repository to see the contents of this simple script. Note that this is the quick and easy way to install tiller, not the most secure way! The values.
Run Rancher 2.4 in Azure with K3s and MySQL
We could have used the chart from the Helm repository but I prefer having the chart in source control. Hopefully, this post together with the GitHub repo gave you some ideas about automating these deployments with Azure DevOps.
All you need to do is create a pipeline from the repo.
