For more\n information, refer to\n [Rollbacks, gradual rollouts, and traffic migration](/kubernetes-engine/enterprise/knative-serving/docs/rollouts-rollbacks-traffic-migration).\n\n- You can optionally use [revision tags](/kubernetes-engine/enterprise/knative-serving/docs/rollouts-rollbacks-traffic-migration#tags)\n to test a revision that is not serving traffic.\n\n- You don't need to [manually delete revisions](#delete), although you can if you want.\n\n- Non-serving revisions do not consume any resources and are not billed.\n\n- There is a maximum of 1000 revisions per service: If you exceed that limit, older revisions are automatically deleted.\n\n- The revision suffix is assigned automatically. If you want to use your own\n version suffix, you can do so using the Google Cloud CLI parameter\n [--revision-suffix](/sdk/gcloud/reference/run/deploy#--revision-suffix).\n\nViewing the list of revisions for a service\n-------------------------------------------\n\n### Console\n\nTo view the list of revisions in your project:\n\n1. Go to Knative serving in the Google Cloud console:\n\n [Go to Knative serving](https://console.cloud.google.com/kubernetes/run)\n2. Locate the service in the services list, and click\n on it.\n\n3. Click the *Revisions* tab to show the list of current revisions for that\n service.\n\n### Command line\n\n\nTo view the list of revisions for a given service:\n\n1. Find your service name from the list of services available in your\n project:\n\n ```bash\n gcloud run services list\n ```\n2. List all the revisions for a service by specifying the name of that\n service in the following command:\n\n \u003cbr /\u003e\n\n ```bash\n gcloud run revisions list --service SERVICE\n ```\n\n \u003cbr /\u003e\n\n Replace \u003cvar translate=\"no\"\u003eSERVICE\u003c/var\u003e with the name of your service.\n\nViewing revision details\n------------------------\n\n### Console\n\nTo view the details of a revision in your project:\n\n1. Go to Knative serving in the Google Cloud console:\n\n [Go to Knative serving](https://console.cloud.google.com/kubernetes/run)\n2. Locate the service in the services list, and click\n on it.\n\n3. Click the *Revisions* tab to show the list of current revisions for that\n service.\n\n4. Select the service revision you are interested in:\n\n5. Examine the *DETAILS* panel at the far right for revision-specific\n information such as the URL of the deployed container image, amount of\n memory allocated, environment variables, and possibly\n [build and source repository information](#build-source).\n\n### Command line\n\nTo view the details of a revision in your project:\n\n1. Find your service name from the list of services available in your\n project:\n\n \u003cbr /\u003e\n\n ```bash\n gcloud run services list\n ```\n\n \u003cbr /\u003e\n\n2. List all the revisions for a service by specifying the name of that\n service in the following command:\n\n \u003cbr /\u003e\n\n ```bash\n gcloud run revisions list --service SERVICE\n ```\n\n \u003cbr /\u003e\n\n Replace \u003cvar translate=\"no\"\u003eSERVICE\u003c/var\u003e with the name of your service.\n3. Display details of a revision by specifying the name of that revision\n in the following command:\n\n \u003cbr /\u003e\n\n ```bash\n gcloud run revisions describe REVISION\n ```\n\n \u003cbr /\u003e\n\n Replace \u003cvar translate=\"no\"\u003eREVISION\u003c/var\u003e with the name of the revision you want to\n learn more about.\n | **Tip:** You can use the [`--format` flag](/sdk/gcloud/reference#--format) to format the output. For example as YAML:\n\n \u003cbr /\u003e\n\n ```bash\n gcloud run revisions describe REVISION --format yaml\n ```\n\n \u003cbr /\u003e\n\nNote that a non-current revision may have the status of `RETIRED`, which means\nthat Knative serving has retired the infrastructure needed for that\nparticular revision.\n\n### About build and source repository information in the *Details* panel\n\nIf the\n[Artifact Analysis API](/container-registry/docs/container-analysis)\nis enabled and the container was built with [Cloud Build](/build),\nbuild information is displayed in the *Details* panel.\n\nAdditionally, if a\n[Cloud Build trigger](/build/docs/running-builds/create-manage-triggers)\nwas used to build the container, source repository information is also displayed\nin the *Details* panel.\n\nDeleting revisions\n------------------\n\nA common use case for deleting a revision is when you want to make sure a\nparticular revision won't be accidentally used.\n\nYou cannot delete a revision if:\n\n- it is able to receive traffic,\n- it is the only revision of the service,\n- it is the latest revision of the service.\n\nWhen you delete a revision, the container image used by this revision is not\ndeleted automatically from Container Registry or Artifact Registry. To delete a\ncontainer image from a registry, see the deletion instructions for\n[Container Registry](/container-registry/docs/managing#deleting_images) or\n[Artifact Registry](/artifact-registry/docs/docker/manage-images#deleting_images).\n\nYou cannot undo a revision deletion.\n\nYou can use either the console or the command line: \n\n### Console\n\nTo delete a revision:\n\n1. Go to Knative serving in the Google Cloud console:\n\n [Go to Knative serving](https://console.cloud.google.com/kubernetes/run)\n2. Locate the service in the services list, and click\n on it.\n\n3. Click the *Revisions* tab to show the list of current revisions for that\n service.\n\n4. Locate the service revision you want to delete.\n\n5. Click the three-dot vertical ellipse to the left of the revision to show\n the *Delete* menu.\n\n6. Click **Delete** to delete the revision.\n\n### Command line\n\nTo delete a revision, use the following command:\n\n\u003cbr /\u003e\n\n```bash\ngcloud run revisions delete REVISION\n```\n\n\u003cbr /\u003e\n\nReplace \u003cvar translate=\"no\"\u003eREVISION\u003c/var\u003e with the name of the revision you want to delete.\n\nWhat's next\n-----------\n\nAfter you deploy a revision, you can do the following:\n\n- [Gradual rollouts, rollback revisions, traffic migration](/kubernetes-engine/enterprise/knative-serving/docs/rollouts-rollbacks-traffic-migration)"]]
