Create:
driver create json_options
Delete:
driver delete json_options
Mount:
driver mount mountpoint json_options
Unmount:
driver unmount mountpoint
Currently we support 2 major use cases
driver does nothing
./cifs create '{"host":"146.148.46.118","export":"/var/cifs"}'
stdout output: {"status":"Success","message":""}
driver does nothing
./cifs delete '{"host":"146.148.46.118","export":"/var/cifs"}'
stdout output: {"status":"Success","message":""}
driver mounts CIFS using pre-existing remote share provided by user
./cifs mount /home/ubuntu/cifsMnt '{"host":"146.148.46.118","export":"/var/cifs","mntOptions":"ro,vers=4.1"}'
mntOptions key-value pair is optional for mount, but host and export are the must
stdout output: {"status":"Success","message":""}
The result is that 146.148.46.118:/var/cifs is mounted at /home/ubuntu/cifsMnt
driver unmount CIFS file system
./cifs unmount /home/ubuntu/cifsMnt
stdout output: {"status":"Success","message":""}
Rancher have default host and export environment variables set on the host identifying default CIFS remote share. Driver will use them to create a directory for each volume during create command and delete it at delete command. For instance:
export HOST=146.148.46.118
export EXPORT=/var/cifs
user supplies volume name, driver creates a directory under default remote share using volume name. The output is the status and newly created directory name
./cifs create '{"mntDest":"/home/ubuntu/mnt","name":"vol1"}'
name represents volume name and mntDest is the mount point this remote volume(HOST:EXPORT/name) will be mounted.
mntDest is needed for driver to temporarily mount remote share in order to create a subdirectory named "name"
stdout output: {"status": "Success”,"options":{"created":true,"name":"vol1”}}
the options map from the output will be passed in as part of json_input for delete command
driver deletes created directory at create phase
./cifs delete '{"mntDest":"/home/ubuntu/mnt", "created":"true", "name":"vol1"}'
the options map from create command output is passed in to delete command as part of json_input
stdout output: {"status":"Success","message":""}
driver mounts CIFS src share using HOST:EXPORT/name created at create command phase
./cifs mount /home/ubuntu/cifsMnt '{"name":"vol1","mntOptions":"ro,vers=4.1"}'
mntOptions key-value pair is optional for mount, but name is a must
stdout output: {"status":"Success","message":""}
The result is that 146.148.46.118:/var/cifs/name is mounted at /home/ubuntu/cifsMnt
driver unmount CIFS remote share
./cifs unmount /home/ubuntu/cifsMnt
stdout output: {"status":"Success","message":""}
