Other updates, such as scaling the Deployment, do not trigger a rollout.\n\nFollow the steps given below to update your Deployment\n\nLet's update the nginx Pods to use the nginx:1.16.1 image instead of the nginx:1.14.2 image.\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl set image deployment.v1.apps/nginx-deployment nginx=nginx:1.16.1\n```\n\nor use the following command\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl set image deployment/nginx-deployment nginx=nginx:1.16.1\n```\n\nwhere deployment/nginx-deployment indicates the Deployment, nginx indicates the Container the update will take place and nginx:1.16.1 indicates the new image and its tag.\n\nBounded code example (external data; do not execute automatically):\n```text\n   deployment.apps/nginx-deployment image updated\n```\n\nAlternatively, you can edit the Deployment and change .spec.template.spec.containers[0].image from nginx:1.14.2 to nginx:1.16.1\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl edit deployment/nginx-deployment\n```\n\nBounded code example (external data; do not execute automatically):\n```text\n   deployment.apps/nginx-deployment edited\n```\n\nTo see the rollout status, run\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl rollout status deployment/nginx-deployment\n```\n\nThe output is similar to this\n\nBounded code example (external data; do not execute automatically):\n```text\n   Waiting for rollout to finish: 2 out of 3 new replicas have been updated...\n```\n\nBounded code example (external data; do not execute automatically):\n```text\n   deployment \"nginx-deployment\" successfully rolled out\n```\n\nGet more details on your updated Deployment\n\nAfter the rollout succeeds, you can view the Deployment by running kubectl get deployments. The output is similar to this\n\nBounded code example (external data; do not execute automatically):\n```text\n  NAME               READY   UP-TO-DATE   AVAILABLE   AGE\n  nginx-deployment   3/3     3            3           36s\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
