Title:
"socket.getaddrinfo" of "metadata.google.internal" fails on GCE
Status in cloud-init:
Expired
Bug description:
When booting an Ubuntu 18.04 based image on GCE, we see the following
messages in the log:
2019-05-30 00:05:27,818 - util.py[DEBUG]: Resolving URL: http://metadata.google.internal/computeMetadata/v1/ took 0.001 seconds
2019-05-30 00:05:27,818 - DataSourceGCE.py[DEBUG]: http://metadata.google.internal/computeMetadata/v1/ is not resolvable
2019-05-30 00:05:27,818 - util.py[DEBUG]: Crawl of GCE metadata service took 0.013 seconds
2019-05-30 00:05:27,818 - DataSourceGCE.py[WARNING]: address "http://metadata.google.internal/computeMetadata/v1/"; is not resolvable
Further, the contents of "/run/cloud-init/instance-data.json" doesn't
have any meaningful data.
What I've found is that, read_md() in DataSourceGCE.py will call
util.is_resolvable_url() on the address
"http://metadata.google.internal/computeMetadata/v1/";, which results
is calling socket.getaddrinfo() for "metadata.google.internal", and
it's this socket.getaddrinfo() call that fails.
This failure appears to be due to the fact that "cloud-init.service"
does not ensure it waits for DNS (i.e. "systemd-resolved.service") to
be working before it runs. I say this because:
1. If I add "After=systemd-resolved.service" to the "cloud-
init.service" definition, this failures goes away.
2. If I run "cloud-init init" after the system has booted up (i.e.
after enough time has passed, such that DNS is working), the failure
doesn't occur.
