Creating the Resonate User trif-user

Resonate RFID Reader Management 2.1 Software Installation Guide

Create the user

trif-user

. This user is required to run

Resonate

. The user will own the installation directory and have access to the Kubernetes cluster. If setting up a multi-node cluster, perform these steps only on the primary node.

Create the required directory:

TRIFECTA_INSTALL_DIRECTORY="/opt/zebra/trifecta"
TRIFECTA_USER="trif-user"

sudo mkdir -p "$TRIFECTA_INSTALL_DIRECTORY"

Create the user trif-user.

For Ubuntu:

sudo adduser --no-create-home $TRIFECTA_USER --home $TRIFECTA_INSTALL_DIRECTORY --shell "$(command -v bash)" --disabled-password --gecos ""

For Red Hat:

sudo adduser --no-create-home $TRIFECTA_USER --home-dir $TRIFECTA_INSTALL_DIRECTORY --shell "$(command -v bash)"

Configure snap home directories (for newer snap versions):

SNAP_VERSION=$(snap version | grep snapd | awk '{print $2}')
if [ "$(printf '%s\n' "$SNAP_VERSION" "2.59" | sort -V | head -n1)" = "2.59" ]; then
    sudo snap set system homedirs="$(dirname $TRIFECTA_INSTALL_DIRECTORY)"
fi

To use snap with other home directories for non-

Resonate

installation purposes (for example, installing security agents), set the

homedirs

parameter to a comma-delimited list of paths (for example,

homedirs="$(dirname $TRIFECTA_INSTALL_DIRECTORY),/home,/other/home"

Set up directories and permissions:

sudo mkdir -p $TRIFECTA_INSTALL_DIRECTORY
sudo mkdir -p $TRIFECTA_INSTALL_DIRECTORY/.kube
sudo chown -R $TRIFECTA_USER $TRIFECTA_INSTALL_DIRECTORY

# Add user to microk8s group
sudo getent group microk8s >/dev/null || sudo groupadd microk8s
sudo usermod -aG microk8s $TRIFECTA_USER

Extract the

Resonate

application from the

trifecta.tar

file:

if [ -f trifecta.tar ]; then
    sudo cp trifecta.tar $TRIFECTA_INSTALL_DIRECTORY/
    sudo chown $TRIFECTA_USER $TRIFECTA_INSTALL_DIRECTORY/trifecta.tar
    sudo -u $TRIFECTA_USER tar xf $TRIFECTA_INSTALL_DIRECTORY/trifecta.tar --no-same-owner --no-same-permissions -C $TRIFECTA_INSTALL_DIRECTORY
    sudo rm $TRIFECTA_INSTALL_DIRECTORY/trifecta.tar
fi
