Final answer:
To run a deployment in Kubernetes, create a YAML deployment file then use 'kubectl apply' to start the deployment, 'kubectl get deployments' to check its status, and 'kubectl rollout status' for detailed rollout information.
Step-by-step explanation:
To run a deployment in Kubernetes, you primarily need to create a deployment configuration. This configuration usually is defined in a YAML file. Here's a step-by-step guide:
- Create a YAML file for your deployment. This file will specify the desired state of your deployment, including the number of replicas, the container image to use, and other relevant configurations.
- Use the kubectl apply command followed by the filename to create the deployment in your Kubernetes cluster. For example: kubectl apply -f deployment.yaml.
- After you have applied the deployment, you can use the kubectl get deployments command to check the status of your deployment and ensure it is running correctly.
- If you need to update your deployment, you can modify the YAML file and reapply it using the kubectl apply command again.
- To see more detailed information about the deployment's rollout status, use kubectl rollout status deployment/<deployment-name>.
Remember that deployments also ensure that your application can be scaled and updated in a controlled way, with zero-downtime rollouts and rollbacks if something goes wrong.
