Continuous deployment with Web App for Containers using Azure Container Registry – Part 6

  • Artikel

This Post is in continuation of Post : https://blogs.msdn.microsoft.com/paraspatidar/continuous-deployment-with-web-app-for-containers-using-azure-container-registry-part-5/ and it is Part 6 of the thread.

To start Over , please begin from Here

Our next steps are from Verifying Continuous Deployment  section .

20. Go to Docker CLI.

21. Modify the image or give the same tag mapping to any other image.

     1) So now to do so , I will download the phpmyadmin container image from docker by running following command :

               docker pull phpmyadmin/phpmyadmin

               clip_image021_thumb1

     2) Now if I verify the images in my docker by running command

          docker images

         it shows something like :

          17_thumb3

    watch carefully here:

      Line 2 : the image NGINX is having tag as latest with image id 40960******
      as I have mapped that image with Azure container registry end point sample1/php,
      Line 1 : my sample1/php end point is having same tag and same image id as line 2.
      This also gives us indication , that currently which image is mapped to our azure registry end point.

   3) Line number 7 : Now my recently downloaded phpmyadmin/phpmyadmin image tag is also latest ,with image id f4674******
        But that is not mapped with my existing azure end point ,
       Thus in line number 9 , that end point with that image id is having Tag as <none>.

   4) Now let me map the phpmyadmin image to azure end point by running following command :
           docker tag phpmyadmin/phpmyadmin myregistry.azurecr.io/samples1/php

      clip_image025_thumb1

   5) Now verify the docker image again to see if it pointing to correct end point

       18_thumb2

  6) Look closely ,

  7) Now line 1 NGINX local image having image id 4096*** with tag latest.

  8) Line number 4 :This same image id 4096*** , the tag has become <none> , that means now NGINX is not pointing to azure end point samples1/php any more

  9) Line number 5 : Phpmyadmin/phpmyadmin local one having image id f46764*** with tag latest ,

  10) Line number 6 : Same image id is now pointing to azure container registry end point samples1/php with tag latest.

  11) From above, we have mapped phpmyadmin/phpmyadmin image to azure container registry and pushing this on on registry will auto deploye phpmyadmin image on our web app , which is currently running nginx image.

22. Push the image to Azure Container Registry.

     docker push myregistry.azurecr.io/samples1/php

     Run following command will push this image on azure registory , which should ideally push it on Azure web app as well .

       clip_image029_thumb1

     Now , in few minutes it should auto deploy phpmyadmin container on my web app

23. Browse the web app to see that new image is up and running.

    clip_image031_thumb2

24. After some time, the auto deployment logs are visible in the Azure Container Registry’s Web hook’s Logs/events
