问题
I'm trying to set up an app on OpenShift Online Next Gen and I need to store a small file at runtime and read it again during startup. The content of the file changes, so I cannot simply add it to my source code.
My project is already up and running, all I need is persistent storage. So, I open the Web Console, click Browse->Storage and it says there are no volumes available. Same things if I go to Browse->Deployments and try to attach a volume.
So, I logged in via cli and issued the following command:
oc volume dc/mypingbot --add --type=pvc --claim-name=data1 --claim-size=1Gi
Now my volume appears both in the Storage section and in the deplyment section. I attach it to my deployment config using the Web Console and set its mount point to /data1.
The deployment process now takes a while and then fails with the following two errors:
Error syncing pod, skipping: Could not attach EBS Disk "aws://us-east-1c/vol-ba78501e": Error attaching EBS volume: VolumeInUse: vol-ba78501e is already attached to an instance status code: 400, request id:
Unable to mount volumes for pod "mypingbot-18-ilklx_mypingbot(0d22f712-58a3-11e6-a1a5-0e3d364e19a5)": Could not attach EBS Disk "aws://us-east-1c/vol-ba78501e": Error attaching EBS volume: VolumeInUse: vol-ba78501e is already attached to an instance status code: 400, request id:
What am I missing?
