JovianDSS CSI plugin configuration

Plugin configuration goes through config file. Config file itself gets provided to plugin in form of Kubernetes secret and has yaml format.

Please take notice that name of a file and the name of secret resource is the same as specified in controller config.

kubectl create secret -n joviandss-csi generic jdss-controller-cfg --from-file ./deploy/cfg/cfg.yaml

If you change config file user have to restart controller service as well.

Here is example config file:

loglevel  : Debug
logpath   : /tmp/csi-log
endpoint:
  name: MainStorage
  addrs:
    - 192.168.0.100
  port: 82
  user: admin
  pass: admin
  prot: https
  pool: Pool-0
  tries: 3
  idletimeout: 5s
iscsi:
  iqn: iqn.csi.2024-04 
  addrs:
    - 192.168.0.100
  port: 3260

  • loglevel the logging level of the plugin. Logging can be done on following levels

    1. Panic
    2. Fatal
    3. Error
    4. Warn
    5. Info
    6. Debug
    7. Trace

  • logpath user can specify file to output log to, by default log would be printed to standard output.

  • endpoint is a section of config file instructing controller on how to connect to JovianDSS endpoint using REST API. REST API have to be enabled on the side of JovianDSS storage to make plugin work.

    • name name of storage, does not affect anything at the moment
    • addrs list of addresses that would be used to send REST commands to storage
    • port port that would be used to connect to storage, this port would be used for every address user provides for addrs
    • pool Pool name of the JovianDSS storage that would be used to store volumes, pool have to be created manually on the side of JovianDSS by user
    • tries how many attempts should be taken to sent single rest request to JovianDSS network interface before failing CSI request.
    • iddletimeout time to wait for REST request to complete before considering it as failed.

  • iscsi is a section of config file containing information on how to connect to JovianDSS iscsi targets.

    • iqn iqn prefix that would be used for target creation
    • addrs list of addresses that would be used to connect targets
    • port iscsi port provided by JovianDSS storage
