Nocalhost's development configuration supports multiple developing ways, such as ConfigMap, Annotations, etc.
In fact, these configuration methods also suit for deployment configuration. Buts some functions need to be implemented through the K8s Admission WebHook. In Nocalhost, a component called
Nocalhost-Dep plays this role, and
Nocalhost Server will automatically deploy this component for you.
if you do not use
Nocalhost Server, then additional deployment of
Nocalhost Dep is required.
What deployment configurations does Nocalhost provide? introduces which deployment configurations require additional deployment of
To make a simple deployment configuration is mentioned in Introduction to Deployment Configuration --- Nocalhost Basic Deployment Configuration. Combining with What configuration methods are supported by Nocalhost-place the configuration in configmap, we can get the configuration:
We have prepared an demo for this, which will automatically deploy
Nocalhost Dep, and use the way of ConfigMap to make the deployment configuration.
Using the following commands to try out this demo (trying the Chart package requires ClusterAdmin)
Then use Helm to install:
The content of the deployment configuration itself will not be repeated here. let's take a look at
This ConfigMap requires to apply to Api Server first. For example, in the Helm application scenario, it should be declared as
.Values.nocalhost.config.path to render the main body of the deployment configuration. The configuration is actually declared in
./charts/bookinfo/example/config-from-cm/nocalhost-full-config.yaml, which is a standard Nocalhost deployment configuration without any additional modification:
The method of usage is exactly the same as Which configuration methods Nocalhost supports-place the configuration in annotations.
Since Annotations closely follow the workload, some configurations at the application level are not supported. Only the configurations under
application.services is supported.
Again, use the same demo project:
Use the following commands to get and try out this project (trying the Chart package requires ClusterAdmin)
Then use Helm to install:
values-annotation-config.yaml as Values.yaml, which specifies the rendering of the local configuration file to the Annotations of the workload. Take
./charts/bookinfo/templates/microservice-details.yaml as an example:
Helm will render the path configured by
.Values.nocalhost.annotations.path.details into yaml, whose content is as follows, that is,
./charts/bookinfo/example/config-from-annotations/details.yaml specified in Values :
We recommend using
Nocalhost Server to get all the functions of
