OpenStack Compute (nova)

cloudpipe instance fails to get payload.b64

Asked by Hyunsun Moon

Hello,
I'm trying to test VPN. I added some scripts to the cloudpipe image's rc.local for fetching user-data from metadata server.(I found the useful scripts from this board).

Here's the script.

----------------------------------------------------------------------
echo Downloading payload from userdata
wget http://169.254.169.254/latest/user-data -O /tmp/payload.b64
echo Decrypting base64 payload
openssl enc -d -base64 -in /tmp/payload.b64 -out /tmp/payload.zip

mkdir -p /tmp/payload
echo Unzipping payload file
unzip -o /tmp/payload.zip -d /tmp/payload/

# if the autorun.sh script exists, run it
if [ -e /tmp/payload/autorun.sh ]; then
  echo Running autorun.sh
  cd /tmp/payload
  sh /tmp/payload/autorun.sh

else
  echo rc.local : No autorun script to run
fi

exit 0

-----------------------------------------------------------------------

I was able to run vpn instance successfully but during the boot processing, I got the following errors so that the OpenVPN server fails to launch. No more debug messages...

Did I miss something?

the autorun.sh script configures the openvpn server, so if there's no autorun script, then we wouldn't expect the vpn server to start. So the root problem is why aren't you getting the autorun.sh script from the payload.zip?

The error message suggests you're connecting to the metadata server, so the network is up.

To get more diagnostic information, you can log into the cloudpipe server, and try executing the rc.local script again, adding some statements to print some diagnostic output.

are you able to 'curl http://169.254.169.254/latest/user-data'?

are you starting the cloudpipe server with 'nova-manage vpn run <project>'?

have you inspected the logfiles in /var/log/nova for the timeperiod of your test?

Hi Barton,
here are the results of curl http://169.254.169.254/latest/meta-data/
local-ipv4
reservation-id
local-hostname
placement/
ami-launch-index
public-hostname
mpi/
hostname
ami-id
public-keys/
instance-action
public-ipv4
block-device-mapping/
ami-manifest-path
security-groups
instance-type
instance-id

It's from the normal instance because I don't know how to log in to the cloudpipe server.
Frequently the same command (curl http://169.254.169.254/latest/meta-data/) occurs the following error!!!
