  5. Install cortx-py-utils

SSPL mini-provisioner configs

SSPL mini-provisioner interfaces are supposed to be executed in order i.e post-install, prepare, config, init. And each stage must be executed on each node before proceeding to next stage. And rest of interfaces can be executed in any order i.e for test, reset, cleanup.

Input config required at each mini provisioner stage is a cumulative i.e. super set of current plus previous stage config. The input config from post-install stage will be available to prepare stage, post-install and prepare stage input config will be available to config stage. Same way, post-install, prepare and config stage input configs to init stage. Init stage is expected to have all configs required for sspl-ll service to start and run smoothly.

At each mini-provisioner stage, argument "--config <template_file>" needs to be passed , which is a reference to required configs backend, depending on the stage.

The template file is a key-value mapped yaml file, maintaining the config requirement template for each stage. All the strings start with TMPL_ should be replaced with valid values. If no values identified, then it can be left blank.

Template fields

  1. TMPL_{field} is a identifier for consumer to update variable keys & values(ex. CI CD pipeline)

    Template fields used accross mini provisioner interfaces

    n will be 1,2 and 3 for first, second and 3rd node

    BMC information such as IP, USER and SECRET can be blank for VM.

    Stage Field Example Value Description Required

  2. Note

    1. Mini provisioner interfaces are supposed to be executed in following order

      1. post-install, prepare, config, init
      2. And when needed, remaining stages has no order dependency to execute, i.e for test, reset, cleanup

    2. Config required at each mini provisioner stage is a super set of current plus previous stage config

Provisioning

  1. Post Install

    1. Run utils post_install on all 3 nodes

      /opt/seagate/cortx/utils/bin/utils_setup post_install --config /tmp/cortx-config-new

    2. Run SSPL post_install on all 3 nodes

      /opt/seagate/cortx/sspl/bin/sspl_setup post_install --config /opt/seagate/sspl/conf/sspl.post-install.tmpl.3-node

  2. Prepare

    1. Run SSPL prepare on all 3 nodes

      /opt/seagate/cortx/sspl/bin/sspl_setup prepare --config /opt/seagate/sspl/conf/sspl.prepare.tmpl.3-node

  3. Config

    1. Run utils config on all 3 nodes

      /opt/seagate/cortx/utils/bin/utils_setup config --config /tmp/cortx-config-new

    2. Run SSPL config on all 3 nodes

      /opt/seagate/cortx/sspl/bin/sspl_setup config --config /opt/seagate/sspl/conf/sspl.config.tmpl.3-node

  4. Init

    1. Run SSPL init on all 3 nodes

      /opt/seagate/cortx/sspl/bin/sspl_setup init --config /opt/seagate/sspl/conf/sspl.init.tmpl.3-node

Start

Run below stpes in all 3 nodes

  1. Start SSPL service

    systemctl start sspl-ll

  2. Check service status

    systemctl status sspl-ll

Note: Starting service using systemctl is recommended only when HA framework is not in place, otherwise service is supposed to be started in Cortx cluster automatically by HA

Test

Run below step in all 3 node to execute tests

Note: Test check features on single node alone(on one which its executed)

  1. Start SSPL tests with plan

    /opt/seagate/cortx/sspl/bin/sspl_setup test --config <config_url> --plan [sanity|alerts|self_primary|self_secondary]

    Ex.

    /opt/seagate/cortx/sspl/bin/sspl_setup test --config <config_url> --plan sanity
