Post-00 cloud native Engineer: use Zadig to increase revenue and reduce expenditure for the R & D of Sichuang Technology (Guangzhou public transport)

This is me and me  Zadig  The story of ！

On the Internet , In the context of digital transformation , Nowadays, Internet travel is very popular , The traditional passenger station has gradually stood on the edge of the city . More and more people choose high-speed rail 、 The plane . More often than not, the passenger station plays a role in tracing back the past youth , It is the first choice for the older generation , Because they don't know much about it “ Trendy stuff ”（ Internet travel ）, But with the change of travel mode , The ticket selling modes of passenger stations are diversified and the travel objectives of individual users remain unchanged , We need to expand diversified ticket selling methods to support users , A large number of users and requirements iteration are right  IT  Infrastructure brings new challenges .

Enterprise R & D bottleneck

Enterprise R & D efficiency is slow , Developers cannot devote themselves to requirements development

As an Internet transformation enterprise in the public transport industry , At a smaller scale, developers can take on “ Full stack engineer ”. All R & D step nodes can be completed with the participation of developers . But with the development of the company , The growth of projects and the multiplicity of demands . When the R & D personnel verify the code , It took too much time . Unable to devote himself to the R & D process .

At the same time, there are also limitations for the idea verification of R & D personnel . Innovation in an industry , It must be the need to test many wild ideas , Only in this way can we finally achieve breakthrough creation . But if we still follow the previous traditional R & D system , Then the possibility of software R & D innovation will develop over time , The R & D personnel are mentally exhausted , No inspiration for innovation .

IT  Technology development is the follow-up and change of its own technology （ Virtualization cannot meet the existing state ）

Traditional virtualization has been gradually realized in the project “ Tired out ”. In the project declaration , Servers usually have some redundant space , But it is precisely this part of the redundant space , At some point it's a waste . We need to make a change , A game that can  IT  Change with the best utilization .

DevOps  And containerization will gradually appear in our follow-up work with the R & D bottleneck .

DevOps  Exploration

Why choose  Zadig？

At first we chose  Jenkins , because  Jenkins  Too famous in the industry . Pull one at random on the side of the road  IT  practitioners , You can ask him  Jenkins  What is it? , He must know . ha-ha . In the subsequent landing , We do use  Jenkins  To make an exploration . At first, I wanted to do the following , But the effect is not ideal .

• Jenkins  The original intention of the first creation is for host services , When it was founded, it was not for  Kubernetes  Leave a convenient door

• Jenkins  There are many ways to do continuous integration deployment  Pipeline  and  Jenkinsfile,Dockerfile  And all kinds of  K8s  service  Yaml  file . Slightly disordered in document management . These things are regular documents , Lack of unified management . And if  Jenkins  If it includes the traditional host deployment projects in the past, it can be said that it will continue to explore , But now, with the large-scale implementation of containerized choreography  Jenkins  We are a little weak here .

• however  Jenkins  It has flexible plug-ins and  Pipeline , It can realize manual intervention and release , This is what we like better . But with the launch and use of the project , It is found that its concurrent construction is slow in the existing environment, so it is temporarily shelved .

• Jenkins Pipeline  In the microservice publishing project , Need modification  Pipeline , Cause unnecessary trouble

• Jenkins  Unable to change the publishing order of the service , You can only manually select sequential publishing in the form of script

In the follow-up work , Found out  Zadig , He became us

Efficient research and development “ Imperial sword ”

.

First time to know  Zadig

Zadig  Actually, I think it's very easy to touch , The premise is that you should understand the basic  K8s  Concept and the basic situation of the language you need to build the service , So you can use it

Take off directly

.

 Zadig  We have an efficient R & D process here , It is embodied in ：

• Efficient management  K8s  service  Yaml,Helm, Micro service  Dockerfile  Template
  , A perfect solution  Jenkins  Various file problems in

• Zadig 
  Perfect support for cloud native projects and host projects
  , Can achieve fish and bear's paw , I want all of them. ！

• In our flat environment , Zadig  The efficiency of can
  Perfect coverage of all our scenes
  .

• Zadig
    The ability of environmental management is very strong
  , It can provide what other tools cannot provide
  Environmental recovery
  Control function , Support different... In different environments  Configmap, Environmental variables, etc

• Zadig  Conduct  
  CI  The acceleration is obvious

• With powerful
  statistics
  modular

We from  1.6  The version starts to use  Zadig , At that time  Zadig  It is still a relatively young one  CI/CD  Tools , But now it has been released to  1.12  了 , There are too many useful functions .

At that time we were

I value very much  Zadig  Yes  Kubernetes CI/CD  Management and control

. You only need to define the related services  Yaml , This  Yaml  You can extract from the template library , It's quite  Nice. Fill in relevant service parameters , Then you can run . And he can customize the running order , It can be said to be very good .

In the follow-up to  Zadig  In the attention of , We found that he gradually launched new products . We are right.  Zadig  Also very confident . We also tried to upgrade later , But at that time on my computer  VMware  It is possible to do virtualization upgrade tests , Production and upgrading with confidence . good heavens , All the services are up , But it's just not accessible  UI  Interface . We can only go back , Later, after we contacted the authorities, we found that  Istio  and  Zadig  Gateway conflict for , During the upgrade, the related parameters are closed before the normal upgrade , Experienced better products . Through this event, I also realized

The open source product community and users are more connected

, So the problem location can be more convenient , Use the product constantly , Constant feedback , The community is constantly polishing , Create a more powerful product , It's a beautiful thing .

Landing and feedback

stay  Zadig  After landing , The development verification of the project has been

Leap forward development

, In the past, the verification was done locally  IDE  start-up , And then local testing , The tester cannot test . But as the  Zadig  Assembly line operation . The iteration speed of services is also getting faster and faster . And in flat projects , Zadig  Sure

Rapid replication validation of the project environment

, Ensure isolation in the environment .

Before that, we might also consider saying that everyone is against this , But with the successful launch of the first project , In the future, people will no longer reject these things . Instead, he took the initiative to talk about going online . After all, who doesn't want to be  “ Single mindedness ”  What about the people ？

meanwhile

It greatly increases the number of verification of development ideas every day

. Greatly improved the R & D efficiency . At the same time, with the containerization of the project , More and more virtual machines are released , Realized  IT  Further high utilization of resources .

How to judge  Zadig  Is it right for you

If your company is promoting digital transformation as we are , Containerized choreography . that  Zadig  Perfect for you .

If your company uses  Jenkins  Do traditional host release management , It's time to  Kubernetes  Implement containerization , that  Zadig  Same for you , It can be done  Jenkins  and  Zadig  Integrated release of

If your company's projects are flat , that  Zadig  Can basically cover  95%  Scene , add  Zadig  Numerous advantages , Why not ？

If your company has just started

Cloud native exploration

, that  Zadig  It's your best choice , Quick start , High community activity . Quick response to questions , It is absolutely possible for your company  DevOps  The landing of the concept provides technical support .

Zadig  Realized value

Zadig  Not just a good  CI/CD  Tools , He is more  DevOps  The practitioner of culture . adopt  Zadig  We have achieved efficient research and development , The daily R & D utilization rate of R & D personnel has been greatly improved compared with the past , Save valuable time to create more product value .

• Iterating against requirements , The daily service requirements are updated

• For development validation , The integration environment resources can be shrunk freely

• Zadig  It not only realizes its own enterprise value , It has also helped solve many bottleneck problems in the development of our software enterprises .

Usage Summary

• At present, the business line of Sichuang technology products  5  strip , among  3  All business lines have been fully connected  Zadig, rest  2  This business line belongs to the traditional business , Low update frequency .

• adopt  Zadig  Management of the 3 Clusters , among  2  Sets of clusters are remote service clusters . Some environments cannot pass through  Kubernetes  To orchestrate containers for remote publishing , adopt zadig Host project for , Implement remote container publishing , Facilitate subsequent business migration .

• Running environment  17  Among them  12  One test 、5  One production , total  200+  Applications , Realized  4000+  Second automated build and deployment , Deployment success rate  99%  above

In terms of release frequency , In the past, developers took the initiative to release , It is deployed locally on the server in the form of packaging , Release . The frequency of one-day release is about  10  Next time up and down . In the access  Zadig  After that, the frequency of code update iterations increased rapidly , A slow day is also 30  about , A quick day  70  Remaining times

Yes  Zadig  And the expectations of the open source community

Hope for the future in terms of development  Zadig  Be able to improve their own activeness in the open source field , Take part in more open source community activities and open source summit preaching , for example ： KubeCon,CloudNativeCon,Open Source Summit  etc. . Hope to let more enterprises , R&d leader , Front line employees can see  Zadig  In the age of cloud primordial  DevOps  A powerful change . Also hope that  Zadig  The community can do better .

As for what else  Zadig  Functional suggestions , I don't make a fool of myself anymore .

• Because I have less technical experience , It is inconvenient to mention .

• Zadig  Companies that have been able to meet the flattening of common technologies in the existing environment  90%  Of  CI/CD  covers . If it must be mentioned, it may be related to project management integration and version control , Cannot be  Zadig  And others such as ：CODING, Zen and other project management software .

Words and deeds so far , Feeling inside , Wish again  Zadig  Better and better .

I also wish  Zadig  The team can do everything in Shanghai , Good health ！！！

Zadig, Let engineers focus more on creating ！ Welcome to join
