description |
While implementing the GCE provider for Juju we found that the metadata API breaks when trying to retrieve certain binary formats. In our case the gz of user-data. The API only streams out the first 5 bytes, encounters what it preceives as a EOF/nil character and truncates the rest of the request.
We've opened an issue with Google directly, but in the meantime a work around is to allow an explicit encoding to be set for the user-data field of the GCE metadata. This will allow use to base64 encode the binary blob, which the API returns the entire contents of without issue. |
[IMPACT] Due to limitations in GCE, binary user-data is mangled when sent as user-data.
[FIX] Allow user to declare binary encoding on user-data.
[VERIFICATION]
1. Create pristine image from -proposed
2. For step 6
3. Boot GCE instance w/ normal user-data, i.e.:
$ cat user-data
#cloud-config
ssh_import_id: [utlemming]
$ gcloud compute instances create <image from step 1> \
--metadata-from-file user-data=user-data
4. Confirm that user-data was parsed properly
5. GZIP user-data, and encode using base64:
gzip -c user-data.txt | base64 > user-data.b64
6. Boot GCE instance w/ user-data.b64 and character encoding meta-data
set:
$ gcloud compute instances create <image from step 1> \
--metadata-from-file user-data=user-data.b64 \
--metadata user-data-encoding=base64
7. Confirm that user-data was consumed; attach /var/log/cloud-init.log
to report.
[RISK] If a user sets the user-data-encoding to base64, but does not provide base64 data the instance will fail to provision. However, since the user has to explicitly setup the circumstances, it is low risk.
[ORIGINAL REPORT]
The GCE datasource uses the long hostname. Hostnames longer than 64 characters can break several tools.
