sharing hostpath

[schollii]

IINM, sharing the PV as done in shared-volume will only work if the pods are run on the same node. If the pods are on different nodes, you will find the passwd file missing when you go to second pod.

One way to ensure this would be to set nodeName property in second pod, to have same value as first pod (determined by scheduler). This overrides the scheduler and will always work even if the reader is running this in a cluster with multiple worker nodes.

Just noticed your note about this when you expand the solution:

If you need to access the same files in a multi-node cluster, you need a volume type that is independent of a specific node.

It might be worth mentioning that an extra method is using the nodeName property.

Other approach could be to use a nodeSelector property on both pods instead, and label one of the nodes accordingly.

It may also be possible with node affinity, although this does not constrain just "hint".

Sure I'll try to
