As an important step in agile development, continuous integration is designed to maintain high quality while accelerating product iteration. Every time when the codes are updated, an automatic test is performed to test the codes and function validity. The codes can only be delivered and deployed after they pass the automatic test, This post describes how to combine Jenkins, one of the most popular integration tools, with Alibaba Cloud Container Service to realize automatic test and image building pushing.
Deploying Jenkins Applications and the Slave Nodes
1. Create a Jenkins orchestration template.
Create a new template and create the orchestration based on the following content.
jenkins: image: 'registry.aliyuncs.com/acs-sample/jenkins:latest' ports: - '8080:8080' - '50000:50000' volumes: - /var/lib/docker/jenkins:/var/jenkins_home privileged: true restart: always labels: aliyun.scale: '1' aliyun.probe.url: 'tcp://container:8080' aliyun.probe.initial_delay_seconds: '10' aliyun.routing.port_8080: jenkins links: - slave-nodejs slave-nodejs: image: 'registry.aliyuncs.com/acs-sample/jenkins-slave-dind-nodejs' restart: always volumes: - /var/run/docker.sock:/var/run/docker.sock labels: aliyun.scale: '1'
2. Use the template to create Jenkins applications and slave nodes.
You can also directly use a Jenkins sample template provided by Alibaba Cloud Container Service to create Jenkins applications and slave nodes.
3. After the successful creation, Jenkins applications and slave nodes will be displayed in the service list.
4. After opening the access endpoint provided by the Container Service, you can use the Jenkins application deployed just now.
Realizing Automatic Test and Automatic Build and Push of Image
Configure the slave container as the slave node of the Jenkins application.
Open the Jenkins application and enter the System Settings interface. Select Manage Node > Create Node, and configure corresponding parameters. See the figure below.
Note: Label is the only identifier of the slave. The slave container and Jenkins container run on the Alibaba Cloud platform at the same time. Therefore, you can fill in a container node IP address that is inaccessible to the Internet to isolate the test environment.
Use the jenkins account and password (the initial password is jenkins) in Dockerfile for the creation of the slave-nodejs image when adding Credential. Image Dockerfile address HERE
1. Create a project to implement the automatic test.
Configure the source code management and code branch. In this example, use GitHub to manage source codes.
Configure the trigger for building. In this example, automatically trigger project execution by combining GitHub Webhooks and services.
Add the Jenkins service hook to GitHub to implement automatic triggering.
Click the Settings tab on the Github project homepage, and click Webhooks & services > Add service and select Jenkins (Git plugin). Enter ${Jenkins IP}/github-webhook/ in the Jenkins hook URL dialog box.
1. http://jenkins.cd****************.cn-beijing.alicontainer.com/github-webhook/
Add a build step of Executes shell type and write shell scripts to execute the test.
The command in this example is as follows.
1. pwd
2. ls
3. cd chapter2
4. npm test
Create a project to automatically build and push images.
Write shell scripts for building and pushing images.
The command in this example is as follows.
a.cd chapter2 b.docker build -t registry.aliyuncs.com/qinyujia-test/nodejs-demo . c.docker login -u ${yourAccount} -p ${yourPassword} registry.aliyuncs.com d.docker push registry.aliyuncs.com/qinyujia-test/nodejs-demo
Automatically Redeploy the Application
Deploy the application for the first time
Use the orchestration template to deploy the image created above to the Container Service and create the nodejs-demo application.
Example
1.
2. express:
3. image: 'registry.aliyuncs.com/qinyujia-test/nodejs-demo'
4. expose:
5. - '22'
6. - '3000'
7. restart: always
8. labels:
9. aliyun.routing.port_3000: express
10.
1. Select the application nodejs-demo just created, and create the trigger.
Add a line to the shell scripts you wrote in Realize automatic test and automatic build and push of image. The address is the trigger link given by the trigger created above.
i.curl 'https://cs.console.aliyun.com/hook/trigger?triggerUrl=***==&secret=***'
Change the Command in the example from Realize automatic test and automatic build and push of image as follows.
i. cd chapter2
ii. docker build -t registry.aliyuncs.com/qinyujia-test/nodejs-demo .
iii. docker login -u ${yourAccount} -p ${yourPassword} registry.aliyuncs.com iv.docker push registry.aliyuncs.com/qinyujia-test/nodejs-demo
v. curl 'https://cs.console.aliyun.com/hook/trigger?triggerUrl=***==&secret=***'
After pushing the image, Jenkins automatically triggers redeployment of the nodejs-demo application.
Configure The Email Notification for the Results
If you want to send the unit test or image configuration results to relevant developers or project execution initiators through email, perform the following configurations.
On the Jenkins homepage, click System Management > System Settings, and configure a Jenkins system administrator email.
Install the Extended Email Notification plugin, configure SMTP server and other relevant information, and set the default recipient list. See the figure below.
The above example shows the parameter settings of the Jenkins application system. The following example shows the relevant configurations for Jenkins projects whose results are to be pushed through email.
1. Add post-building operation steps in the Jenkins project, select Editable Email Notification, and enter a recipient list.
2. Add a mailing trigger.

I posted before about AWS, Azure and OCI but this time i am trying to cover Alibaba , in this post i will show you how to setup your first Compute instance whatever OS you want CentOS or Ubuntu depeds on what you want
What you need ?
Connect to your Alibaba Cloud
Locate the Internet IP address (Public IP address) associated with your Alibaba Cloud ECS Instance.
If you are running Linux or Mac, use a terminal application to connect to the instance via SSH. If you are on Windows, you can use PuTTy.
Change the Hostname
The hostname is a default identifier when you communicate to a Linux server. It is like a computer name that is associated with your home PC or laptop. Naming your CentOS 7 server with a descriptive hostname helps you to differentiate your machines especially if you are running a bunch of them.
check the update
$ sudo yum update
check your hostname
$ hostname
change your hostname, we need to install nano text editor using the command below:
$ sudo yum install nano
Then, edit the /etc/cloud/cloud.cfg file and find the entry preserve_hostname. Change its value from false to true.
$ sudo nano /etc/cloud/cloud.cfg
preserve_hostname true
Then, edit the /etc/hostname file using a nano editor by typing the command below:
$ sudo nano /etc/hostname
You will need to add two entries on this file just below the 127.0.0.1 localhost entry. The first entry you are adding uses the loopback interface address 127.0.1.1. Please note that this is different from the address 127.0.0.1 which have a ‘localhost’ value in the same file.
Reboot your Alibaba Cloud ECS instance for the changes to take effect by typing the command below:
$ sudo reboot
Also you can create non root user by
$ sudo adduser
For instance, to add a user identified as osama on your server, use the command below:
$ sudo adduser osama
Next, we assign a password to the user we have created above:
$ sudo passwd osama
now assign the administrative task to this user
$ sudo gpasswd -a osama wheel
Cheers

Regarding to Wikipedia, Serverless computing is a cloud computing execution model in which the cloud provider runs the server, and dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity
Today i will show you an example how to create serverless website but this time not using Amazon AWS, Azure or OCI but Alibaba Cloud Provider.
Create a Function Compute Service
Go to the console page and click through to Function Compute.
Click the add button beside Services.
In the Service slide out, give your service a name, an optional description, and then slide open the Advanced Settings.
In Advanced Settings you can grant access for Functions to the Internet, to VPC resources, and you can attach storage and a log service to a Function. You can also configure roles.
For our tutorial, we will need Internet access so make sure this configuration is on.
We will leave VPC and Log Configs as they are.
In the Role Config section, select Create New Role, and in the dropdown list pick AliyunOSSReadOnlyAccess as we will be accessing our static webpages from an Object Storage Service bucket.
Click Authorize.
You will see a summary of the Role you created.
Click Confirm Authorization Policy.
You have successfully added the Role to the Service.
Click OK.
ou will see the details of the Function Compute Service you just created.
Now let’s create a Function in the Service. Click the add button next to Functions.
You will see the Create Function process. The first part of the process is Function Template.
There are many Function Templates available, including an empty Function for writing your own bespoke Functions.
Alibaba Cloud-supplied Template Functions are very useful as they have relevant method invocation and demo code for getting started quickly with Function Compute.
let’s choose the flask-web Function written in Python2.7.
Click Select.
We are now at the Configure Triggers section of creating a Function.
Select HTTP Trigger from the dropdown list. Give the Trigger a name and choose Authorization details (anonymous does not require authorization).
Choose your HTTP methods and click Next. We are going to build a simple web-form application so we will need both the GET and POST HTTP methods.
Now we arrive at the Configure Function Settings.
Give the Function a name then scroll down to Code details.
We’ll leave the supplied code for now. Scroll down to below the code sample.
You will see Environment Variable input options and Runtime Environment details.
Click Next.
Click Next at Configure Function Permissions.
Verify the Configuration details and click Create.
You will arrive at the Function’s IDE. Here you can enter new code, edit the code directly, upload code folders, run, test, and fix your code.
Scroll down.
Copy the URL as we will need to add this to our static webpages so they can connect to our Function Compute Service and Function.
Set Up and Configure an OSS Bucket
Click through to Object Storage Service on the Products page.
If you haven’t yet activated Object Storage Service, go ahead and activate it. In the OSS console, click Create Bucket.
Choose a name for the OSS Bucket and pick the region – you cannot change the region later. Select the Storage Class – you also cannot change this later.
We have selected Public Read for the Access Control List.
When you’re ready, click OK.
You will see the Overview page for your bucket. Make a note of the public Internet URL.
In the Files tab, upload your static web files.
I uploaded a simple index.html homepage and a background picture.
<script type="text/javascript">
const functionURL = '<<Function URL>>';
const doHome = new XMLHttpRequest();
doHome.open('GET', functionURL, true);
doHome.onload = function () {
document.getElementById('home_message').innerHTML = doHome.responseText;
};
doHome.send();
</script>
In Basic Settings, click Configure to configure your Static Pages.
Add the homepage details and click Save.
Now go to a new browser window and access the OSS URL you saved earlier.
Back in the Function Compute console, you can now test the flask-app paths directly from the code.
We already tested index.html with no Path variable. Next, we test the app route signin with GET and check the Headers and status code.
The signin page code is working correctly. You can also check the Body to make sure the correct HTML will render on the page. Notice that because I entered the path variable, signin is appended to the URL.
Of course, any errors you encounter will show up in the Logs section for easy debugging.
Now, let’s test this page on the Internet.
If you get an error here, implement a soft link for the page in OSS. Go to the OSS bucket and click More dropdown for the HTML file in question and choose Set soft link.
Give the link a name and click OK.
A link file will appear in the list of static files and you will now be able to access the page online with the relevant soft link and it will render as above.
Back in Function Compute, we can test the POST method in the console with the correct username and password details in the same way.
Add the POST variables to the form upload section in the Body tab.
Now you can test this function online.

I had chance to work and test alibaba cloud, so i thought it’s good idea to write something about it since i already used AWS, Azure and OCI and this is will be my 4th cloud vendor.
Alibaba Cloud is the subsidiary of the e-commerce hub Alibaba Group. The group launched its cloud services in 2009. Today, cloud is the most ambitious project of Alibaba Group where they are investing their hard efforts to win over AWS.
The company has an exclusive range of cloud computing products and services that are divided into 7 categories of Elastic Computing and Networking, Security and Management, Database, Application Services, Domains and website, Storage and CDN and Analytics. Customers of Alibaba Cloud are eligible to get the benefits of cloud security, record breaking computing power, cloud security, safeguard your data, etc.
I really like the cloud and the portal, it’s very simple and ease of use, include to this, having a lot of different features same as AWS, you can check them from here.
the alibaba cloud known as different name also, Aliyun, Alibaba Cloud has 19 regional data centres globally, including China North, China South, China East, US West, US East, Europe, United Kingdom, Middle East, Japan, Hong Kong, Singapore, Australia, Malaysia, India, and Indonesia, right now the Data Center in Germany is operated by Vodafone Germany
Some of the clients that using this cloud : Ford, Air Aisa, Lazada, and more.
Some of the services that providing by alibaba:-
and will discuss each one of them in different post, the next one will be alibaba services.

DevOps is the union of people, process, and products to enable continuous delivery of value to your end users. Azure DevOps is a set of services that gives you the tools you need to do just that. With Azure DevOps, you can build, test, and deploy any application, either to the cloud or on premises. DevOps practices that enable transparency, cooperation, continuous delivery and continuous deployment become embedded in your software development lifecycle.
Azure DevOps provides several tools you can use for better team collaboration. It also has tools for automated build processes, testing, version control, and package management. That’s quite a bit to cover! We’ll get to all the tools eventually. For now, let’s follow the team as they begin with an overview of what Azure DevOps is and how they can get started.
Azure DevOps Services | Descriptions |
Azure Boards | agile tools that help us plan, track, and discuss our work, even with other teams. |
Azure Pipelines | build, test, and deploy with CI/CD that works with any language, platform, and cloud. |
Azure Test Plans | manual and exploratory testing tools. |
Azure Repos | provide unlimited, cloud-hosted private, and public Git repos. |
Azure Artifacts | create, host, and share packages. |
What is Agile?
Agile is a term that’s used to describe approaches to software development, emphasizing incremental delivery, team collaboration, continual planning, and continual learning. Agile isn’t a process as much as it is a philosophy or mindset for planning the work that a team will do. It’s based on iterative development and helps a team better plan for and react to the inevitable changes that occur in software development. Let’s listen in on Mara’s discussion with Andy after the latest release.
Recommendations for adopting Agile
What is Azure Boards?
Azure Boards is a tool in Azure DevOps to help teams plan the work that needs to be done. The Tailspin team will use this tool to get a better idea of what work needs to be done and how to prioritize it.
Set up Azure Boards using the Basic process
Title | Description |
Create a Git-based workflow | Migrate source code to GitHub and define how we’ll collaborate. |
Create unit tests | Add unit tests to the project to help minimize regression bugs. |
Drag Stabilize the build server to the top of the stack. Then, drag Create a Git-based workflow to the second item position. Your final board looks like this.
Assign tasks and set the iteration
