Manage multiple Astra Trident instances

Multiple instances of Trident are needed when you desire to have multiple storage configurations available simultaneously. The key to multiple instances is to give them different names using the --alias option with the containerized plugin, or --volume-driver option when instantiating Trident on the host.

Steps for Docker managed plugin (version 1.13/17.03 or later)

  1. Launch the first instance specifying an alias and configuration file.

    docker plugin install --grant-all-permissions --alias silver netapp/trident-plugin:21.07 config=silver.json

  2. Launch the second instance, specifying a different alias and configuration file.

    docker plugin install --grant-all-permissions --alias gold netapp/trident-plugin:21.07 config=gold.json

  3. Create volumes specifying the alias as the driver name.

    For example, for gold volume:

    docker volume create -d gold --name ntapGold

    For example, for silver volume:

    docker volume create -d silver --name ntapSilver

Steps for traditional (version 1.12 or earlier)

  1. Launch the plugin with an NFS configuration using a custom driver ID:

    sudo trident --volume-driver=netapp-nas --config=/path/to/config-nfs.json

  2. Launch the plugin with an iSCSI configuration using a custom driver ID:

    sudo trident --volume-driver=netapp-san --config=/path/to/config-iscsi.json

  3. Provision Docker volumes for each driver instance:

    For example, for NFS:

    docker volume create -d netapp-nas --name my_nfs_vol

    For example, for iSCSI:

    docker volume create -d netapp-san --name my_iscsi_vol
