Continuous deployment with Web App for Containers using Azure Container Registry – Part 5

 

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-4/ and it is Part 5 of the thread.

To start Over , please begin from Here

Our next steps are from Setting up Continuous Deployment for Azure Web app for container for that Image section .
16. Enable the auto deployment mode on Web app.

In the App settings, add an app setting called DOCKER_ENABLE_CI with the value true.

 

17. Get the service URL from publishing profile.

For the Webhook URL, you need to have the following endpoint: https://<publishingusername>:<publishingpwd>@<sitename>.scm.azurewebsites.net/docker/hook.
You can obtain your publishingusername and publishingpwd by downloading the web app publish profile using the Azure portal.

 

So service url looks like :

https://<publishingusername>:<publishingpwd>@<sitename>.scm.azurewebsites.net/docker/hook.

 

18. Go to Azure Container Registry & create Web hook.

Couple of values which you will require are :
Webhookname : any meaning full name
Service URI : the service uri from step number 17 something like below :
https://<publishingusername>:<publishingpwd>@<sitename>.scm.azurewebsites.net/docker/hook.

Scope : this will be in format of Image:Tag (see point number 5,9 & 11 from previous posts)

Thus earlier we have been using Image as samples1/php and by default the tag was latest ,
Thus the value here will be samples1/php :latest
I have created one more image names samples1/php with tag latest and that what is being shown here in figure.

 

19. Fill up the values and save and do a test ping.

Sometime your kudu is down or process not running ,thus you may encounter error , please make sure your KUDU process is running while ping or deployment .
Now your continuous deployment is up and running, you can test it with deploying modified image or new image with same tag , lets see how to do it ?

Here, to setup and test auto deployment,  either we can do:

Real life Practical Scenario :
1) Modify the locally residing nginx image
2) rebuild it so that changes are persistence
3) push the new image on Azure portal to verify it should auto deploy .

OR

Quickly do a tricky way , just to check auto deployment and get confident in it
1) Or we can do a trick by using another container image lets say phpmyadmin docker image.
2) tag it with same name/endpoint as nginx end point in docker/CMD cli.
3) Push that image so that it can be auto deploy  to azure web app .
4) so now our Azure Web app will show phpmyadmin page on browsing, which is also a verification that auto deployment worked.

I am going to show second way by putting phpmyadmin image via continuous deployment , which will override the nginx image automatically if everything has been setup correctly , this will show that setup is successful.

in practical scenario , you will actually be modifying actual image and build and re-upload it , which we will see in this post Here :
