az acr build -t myname:ver01 -r apptestregistry .<\/em><\/li>\n<\/ul>\nThat’s all there is to it, repeat for each WebApi you want to deploy.<\/p>\n
To check all went well. We’re going to use the following az command to list the Azure registry (change the registry name to yours)<\/p>\n
\r\naz acr repository list --name apptestregistry\r\n<\/pre>\nOr you can go to the Azure container registry dashboard and select Repositories<\/em><\/p>\nDeploying to Kubernetes<\/strong><\/p>\nAt this point we’ve created our WebApi, dockerized it and deployed to the Azure registry of our choice, but to get it into k8s we need to create the k8s manifests.<\/p>\n
We create a YML file, for example kubernetes-manifest-myname.yaml (change myname to the name of your service as well is with the YML below, don’t forget to change apptestregistry to your registry name also)<\/p>\n

\r\nkubectl get pods\r\n<\/pre>\nIf you notice Status or ImagePullBackOff then it’s possible you’ve not set up the integration of k8s and your registry, to be sure type “kubectl describe pod” along with your pod name to get more informations.<\/em><\/p>\nand finally, let’s check the status of our services using<\/p>\n
\r\nkubectl get services\r\n<\/pre>\nIn the Azure Kubernetes services dashboard you can select Services and ingresses<\/em> to view the newly added service(s).<\/p>\nWe can see Cluster IP<\/em> address which is an internal IP address. So for example if our myname<\/em> service has Cluster IP 10.0.40.100 then other services deployed to the cluster can interact with the myname<\/em> service by this IP.<\/p>\nExternal facing service<\/strong><\/p>\nWe’ve created an service which is hosted in a pod within k8s but we have no external interface to it. A simple way to create an external IP from our service is by declaring a service as a load balancer which routes calls to the various services we’ve deployed. <\/p>\n
So let’s assume we created a new WebApi, with Docker support and we added the following controller which routes operations to a single endpoint in this case, but ofcourse it could route to any WebApi that we’ve deployed via it’s Cluster IP<\/p>\n
\r\n[ApiController]\r\n[Route("[controller]")]\r\npublic class MathController : Controller\r\n{\r\n [HttpGet("Get")]\r\n public async Task<string> Get(string op)\r\n {\r\n var httpClient = new HttpClient();\r\n using var response = await httpClient.GetAsync($"http:\/\/10.0.40.100\/myname\/get?operation={op}");\r\n return await response.Content.ReadAsStringAsync();\r\n }\r\n}\r\n<\/pre>\nOnce we have an External IP<\/em> associate with this load balance type of service, then we can access from the web i.e. http:\/\/{external-ip}\/myservice\/get?op=display<\/p>\n","protected":false},"excerpt":{"rendered":"We’re going to be deploying our web services to k8s using Docker, so first off we need to create a registry (if you don’t already have one) on Azure.
