Introduction to template set

stay BCS in , The template collection is Kubernetes Collection of profile templates . You can form a template set by configuring multiple applications , To simplify the complexity of service management ; You can also set the frequently modified data in the template as variables , To facilitate maintenance .

adopt 『 Template set 』+『 Variable 』 It will be very convenient to manage your business .

1、 understand “ service ”

If your service consists of multiple applications , adopt Template set + Variable Generate “ application ” It will be very convenient to manage your service .

For your convenience , This article will take a simple Nginx Service as an example . There is only one under this service Nginx application , By modifying NGINX_PORT The value of the variable , Deploy applications to different namespaces with different ports .

2、 Create a template set

Push image to warehouse

Before creating a template , First, the following steps will Nginx The image of the application is pushed to the image warehouse of the blue whale container service .

Get the compressed package of the image

Execute locally docker save Get the image compressed package , You can also click download directly nginx.tar.

docker pull nginx
docker save nginx > nginx.tar

In this case , Just create one Deployment. First fill in some basic information , Include the name 、 describe , Number of instances .Kubernetes Use selector （spec.selector.matchLabels） Linked resources , So when creating a template, you need to put a fixed label on the application , And add this tag to the selector . Click on the 【Pod Template settings 】, Set the network policy to Host Pattern , You can use the host network directly , take Nginx The container port is exposed .

Then define Nginx Containers , You need to fill in the name 、 describe , choice Nginx Mirror image , At the same time, set the container port to a variable , In this way, applications can be deployed to different namespaces with different ports (nginx Default listening 80 port , The use of variables here is only for example effect , When actually specified, it is set to 80).

Click on the 【 preservation 】 Button , Save the template set to a version .

3、 Set a variable

A set of templates , By setting variables , Different template set instances can be instantiated . The variables are 3 Types ： Global variables 、 Cluster variables and namespace variables .

Global variables ： A variable that has only one value under a project . Such as in the system variable ： project ID、 Business ID
Cluster variables ： The same variable can set different values for different clusters . Such as in the system variable ： colony ID、 Warehouse domain name
Namespace variables ： The same variable can set different values for different namespaces

Be careful ： Variables under the same project key No repetition
