All Longhorn versions.

Symptoms

Not able to create the support bundle with a web browser.

Solution

1. Expose Longhorn backend service. Below is an example using NodePort, you can also export via load balancer if one is set up.

   ip-172-30-0-21:~ # kubectl -n longhorn-system     patch svc longhorn-backend -p '{"spec":    {"type":"NodePort"}}'
   service/longhorn-backend patched
   ip-172-30-0-21:~ # kubectl -n longhorn-system get     svc/longhorn-backend
   NAME               TYPE       CLUSTER-IP          EXTERNAL-IP   PORT(S)          AGE
   longhorn-backend   NodePort   10.43.136.157       <none>        9500:32595/TCP   156m
   

2. Run the below script to create and download the support bundle. You will need to replace the BACKEND_URL, ISSUE_URL, ISSUE_DESCRIPTION.

   # Replace this block ====>
   BACKEND_URL="18.141.237.97:32595"
   
   ISSUE_URL="https://github.com/longhorn/longhorn/issues/dummy"
   ISSUE_DESCRIPTION="dummy description"
   # <==== Replace this block
   
   # Request to create the support bundle
   REQUEST_SUPPORT_BUNDLE=$( curl -sSX POST -H 'Content-Type: application/json' -d '{ "issueURL": "'"${ISSUE_URL}"'", "description": "'"${ISSUE_DESCRIPTION}"'" }' http://${BACKEND_URL}/v1/supportbundles )
   
   ID=$( jq -r '.id' <<< ${REQUEST_SUPPORT_BUNDLE} )
   SUPPORT_BUNDLE_NAME=$( jq -r '.name' <<< ${REQUEST_SUPPORT_BUNDLE} )
   echo "Creating support bundle ${SUPPORT_BUNDLE_NAME} on Node ${ID}"
   
   while [ $(curl -sSX GET http://${BACKEND_URL}/v1/supportbundles/${ID}/${SUPPORT_BUNDLE_NAME} | jq -r '.state' ) != "ReadyForDownload" ]; do
     echo "Progress: $(curl -sSX GET http://${BACKEND_URL}/v1/supportbundles/${ID}/${SUPPORT_BUNDLE_NAME} | jq -r '.progressPercentage' )%"
     sleep 1s
   done
   
   curl -X GET http://${BACKEND_URL}/v1/supportbundles/${ID}/${SUPPORT_BUNDLE_NAME}/download --output /tmp/${SUPPORT_BUNDLE_NAME}.zip
   echo "Downloaded support bundle to /tmp/${SUPPORT_BUNDLE_NAME}.zip"
