To deploy a web application in OpenShift using the command-line interface (CLI), follow these steps:
- Create a new project: Before deploying your application, you need to create a new project. You can do this using the
oc new-project
command. For example, to create a project named “myproject”, run the following command:javascriptCopy codeoc new-project myproject
- Create an application: Use the
oc new-app
command to create a new application from a source code repository, Docker image, or binary file. For example, to create an application from a GitHub repository, run the following command:javascriptCopy codeoc new-app https://github.com/myuser/myapp.git
This will create a new application and automatically configure the necessary resources, such as a build configuration, deployment configuration, and service. - Monitor your application: Once your application is deployed, you can monitor its status and performance using the
oc status
andoc logs
commands. For example, to view the status of your application’s pods, run the following command:luaCopy codeoc status
To view the logs for your application’s pods, run the following command:phpCopy codeoc logs <pod-name>
In addition to the oc new-app
command, you can also use the oc create
command to manually create resources such as pods, services, and routes. For example, to create a new service, run the following command:
oc create service clusterip myservice --tcp=8080:8080
This will create a new service named “myservice” that maps port 8080 on the container to port 8080 on the service.
In summary, deploying a web application in OpenShift using the command-line interface involves creating a new project, creating an application using the oc new-app
command, and monitoring your application using the oc status
and oc logs
commands. You can also manually create additional resources using the oc create
command.
