Description Scott Dodson 2016-08-15 15:55:45 UTC
I'm working on automated installation and when I detect that all the metrics components aren't running and we have a failed deployer pod I attempt to re-run the deployer with MODE=refresh. When I do that I get the following error.

OCP 3.3 environment.

[root@ose3-master ~]# oc version
oc v3.3.0.19
kubernetes v1.3.0+507d3a7
features: Basic-Auth GSSAPI Kerberos SPNEGO

openshift v3.3.0.19
kubernetes v1.3.0+507d3a7

Comment 4 Matt Wringe 2016-08-16 14:20:11 UTC
What is failing is the 'oc label pod' command.

Can you please verify that you can run this command against another pod in your system?

eg "oc label pod ${POD_NAME} foo=bar"

If this command fails then we need to notify the team responsible for the oc commands.

Comment 5 Matt Wringe 2016-08-16 14:22:08 UTC
Actually, I am just going to assign this to the CLI team. I can't see this being something wrong with the metric pods.

Comment 6 Scott Dodson 2016-08-16 20:12:05 UTC
Happened with oc v3.3.0.12 versus v3.3.0.21 API. Closing as not a bug as we don't assure compat between  pre-release builds.

Comment 7 Fabiano Franz 2016-08-16 20:37:45 UTC
Thanks Scott, just for the record then although I didn't use the specified IMAGE_PREFIX and IMAGE_VERSION, I couldn't reproduce the issue.

$ oc new-app -f metrics-deployer.yaml -p -p USE_PERSISTENT_STORAGE=false -p MODE=refresh -p CASSANDRA_NODES=1 -p CASSANDRA_PV_SIZE=10 -p USER_WRITE_ACCESS=true

$ oc logs metrics-deployer-fg2pg -f
validate_master_accessible: ok
validate_hostname: The HAWKULAR_METRICS_HOSTNAME value is deemed acceptable.
validate_deployer_secret: ok
Deleting any previous deployment (leaving route and PVCs)
POD_NAME metrics-deployer-fg2pg
pod "metrics-deployer-fg2pg" labeled

In your logs I see the following line:

'The Pod "metrics-deployer-78dp2" is invalid.'

Might be related to the issue. 'oc' won't be able to label the pod if it's invalid.
