Provisioning data volumes for containers running in virtual machines

A non-transitory computer readable medium comprising instructions to be executed in a computer system having a virtualization software on which a virtual machine is run, the virtualization software supporting execution of the virtual machine in which a container is run, the virtual machine comprising a guest operating system on which the container executes, the container comprising one or more applications deployed therein, wherein the instructions when executed cause the computer system to carry out a method of provisioning a data volume for the container, said method comprising:

• monitoring, by the virtualization software, a designated virtual socket of the virtual machine, wherein the virtual socket enables the virtual machine to communicate with the virtualization software;
• based on said monitoring, detecting, by a component running within the virtualization software, a request from a plug-in of the container to create a data volume, the data volume backed by a storage device, the plug-in providing an interface between the container and the virtualization software, wherein the virtualization software is configured to provide an interface between the plug-in and the storage device;
• and
• upon detecting the request, communicating, by the component, the request to the virtualization software to cause the virtualization software to create the data volume.

A computer system having a first host computer system including a first virtualization software on which a first virtual machine is run, the virtualization software supporting execution of the first virtual machine in which a first container is run, and a second host computer system including a second virtualization software supporting execution of a second virtual machine in which a second container is run, the first virtual machine comprising a guest operating system on which the first container executes, the first container comprising one or more applications deployed therein, wherein the first virtualization software has a first background process running therein to perform the steps of:

• monitoring, by the virtualization software, a first designated virtual socket of the first virtual machine, wherein the first designated virtual socket enables the first virtual machine to communicate with the first virtualization software;
• based on the monitoring of the first designated virtual socket, detecting a request from a plug-in of the first container to create a data volume, the data volume backed by a storage device, the plug-in providing an interface between the container and the virtualization software, wherein the virtualization software is configured to provide an interface between the plug-in and the storage device;
• and
• upon detecting the request, communicating the request to the first virtualization software to cause the first virtualization software to create the data volume.
