gcloud

The following example returns a configurable 3xx response code, sets the Location response header with the appropriate URI, and replaces the host and path as specified in the redirect action.

  1. Export the existing URL map using the gcloud compute url-maps export command:

    gcloud compute url-maps export web-map-http \
  --destination=lb-map-config.yaml \
  --global

  2. Update the URL map file lb-map-config.yaml by adding this to the end of the file:

    hostRules:
- hosts:
  - '*'
  pathMatcher: path-matcher-1
name: web-map-http
pathMatchers:
- defaultUrlRedirect:
    hostRedirect: NEW_HOSTNAME # Omit to keep the requested host
    httpsRedirect: false
    pathRedirect: /NEW_PATH # Omit to keep the requested path
    redirectResponseCode: MOVED_PERMANENTLY_DEFAULT
    stripQuery: true
  name: path-matcher-1

  3. Update the URL map using the gcloud compute url-maps import command:

    gcloud compute url-maps import web-map-http \
   --global \
   --source=lb-map-config.yaml
