Dynamic provisioning of container storage

A computer-implemented method executing by at least one microprocessor, computer-readable instructions stored in at least one non-transitory storage medium coupled to said at least one microprocessor, said method comprising the steps of:

• (a) executing a container engine on a host, said container engine making a request to delete a storage volume having a volume id;
• (b) configuring said container engine to pass said request and said volume id to a container storage integration service (CSIS) integrated with said container engine;
• (c) configuring said CSIS to pass said request and said volume id to a storage allocation module (SAM);
• (d) configuring said SAM to create a global lock file and to read storage allocation persistence (SAP) information from a first partition of each of one or more storage devices and then to determine a list of one or more partitions comprising said storage volume;
• (e) configuring said SAM to pass said list to a dynamic volume manager (DVM) and configuring said DVM to delete said storage volume;
• and
• (f) configuring said SAM to mark as unused said SAP in those amongst said one or more storage devices having partitions in said list, and then to delete said global lock file.

A dynamic container storage system comprising at least one non-transitory storage medium storing computer-readable instructions and at least one microprocessor coupled to said at least one non-transitory storage medium for executing said computer-readable instructions, said system configured to:

• (a) execute a container engine on a host, wherein said container engine makes a request to create a storage volume of a required size for one or more containers managed by said container engine;
• (b) instruct a storage configuration manager (SCM) to provision one or more storage devices on said host and to partition said one or more storage devices into one or more partitions;
• (c) provide said container engine to pass said request to a storage allocation module (SAM) via a container storage integration service (CSIS);
• (d) provide said storage allocation module (SAM) to create a global lock file, and then to read storage allocation persistence (SAP) information from a first partition of each of said of one or more storage devices, and then to create an optimal list of one or more partition ids with corresponding partitions having a total size equal to or exceeding said required size;
• (e) provide a dynamic volume manager (DVM) to create a logical volume over said corresponding partitions with partition ids in said optimal list, and then to pass a volume id of said logical volume to said container engine via said CSIS;
• and
• (f) further provide said SAM to update said SAP in those of said of one or more storage devices whose partition ids are included in said optimal list and then to remove said global lock file.
