Container storage system in remote pods in Kubernetes

A system comprising:

• a memory having computer readable instructions;
• and
• one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
• determining, by a worker node virtual machine, that a volume is available for attachment to the worker node virtual machine;
• using an intermediary software of the worker node virtual machine to cause a pod container storage interface to attach the volume to a pod virtual machine;
• and
• in response to attaching the volume to the pod virtual machine, using the intermediary software of the worker node virtual machine to cause the pod container storage interface to mount the volume to the pod virtual machine such that the volume is available for use by the pod virtual machine, wherein the intermediary software is configured to:
• pull an image for a container to be created in an isolated computing environment on the worker node virtual machine;
• create the container in the isolated computing environment using the image;
• pause the container in the isolated computing environment;
• and
• in response to pulling the image for the paused container, use the isolated computing environment on the worker node virtual machine as a proxy for mounting the volume to the pod virtual machine based on an address, to the paused container within the isolated computing environment, being reassigned to the pod virtual machine.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processors to cause the one or more processors to perform operations comprising:

• determining, by a worker node virtual machine, that a volume is available for attachment to the worker node virtual machine;
• using an intermediary software of the worker node virtual machine to cause a pod container storage interface to attach the volume to a pod virtual machine;
• and
• in response to attaching the volume to the pod virtual machine, using the intermediary software of the worker node virtual machine to cause the pod container storage interface to mount the volume to the pod virtual machine such that the volume is available for use by the pod virtual machine, wherein the intermediary software is configured to:
• pull an image for a container to be created in an isolated computing environment on the worker node virtual machine;
• create the container in the isolated computing environment using the image;
• pause the container in the isolated computing environment;
• and
• in response to pulling the image for the paused container, use the isolated computing environment on the worker node virtual machine as a proxy for mounting the volume to the pod virtual machine based on an address, to the paused container within the isolated computing environment, being reassigned to the pod virtual machine.
