1. Run:

(
  set -x; cd "$(mktemp -d)" &&
  OS="$(uname | tr '[:upper:]' '[:lower:]')" &&
  ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&
  KREW="krew-${OS}_${ARCH}" &&
  curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz" &&
  tar zxvf "${KREW}.tar.gz" &&
  ./"${KREW}" install krew
)

2. Add the following line to ~/.bashrc:

export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"

3. Install T4K Log Collector:

kubectl krew index add tvk-plugins https://github.com/trilioData/tvk-plugins.git
kubectl krew update
kubectl krew install tvk-plugins/tvk-log-collector
#kubectl krew upgrade tvk-log-collector # upgrade the tvk-log-collector plugin
#kubectl krew uninstall tvk-log-collector # uninstall

4. Use it:

kubectl tvk-log-collector --clustered --log-level debug

The paths inside the target have the following format:

./<target_path>/76eef5b5-c47e-4a0e-a678-2d5c07e14cc1/263a4aae-bde1-49cd-8685-b3869328f0b4

^ First UID is from BackupPlan: kubectl get backupplan <bakplan> -o jsonpath='{.metadata.uid}'
^ Second UID is from Backup: kubectl get backup <bak> -o jsonpath='{.metadata.uid}'

# When using ClusterBackup, we will have three directories under <target_path> (considering we are backing up 2 namespaces):
# ./<target_path>/<ClusterBackupPlan_UID>/<ClusterBackup_UID>
# ./<target_path>/<BackupPlan_NS1_UID>/<Backup_NS1_UID>
# ./<target_path>/<BackupPlan_NS2_UID>/<Backup_NS2_UID>

Connecting to and testing a S3 bucket:

sudo apt install -y awscli # Ubuntu
sudo yum install -y awscli # RHEL
#curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" && unzip awscliv2.zip && sudo ./aws/install # if no repos are available
#sudo pip3 install awscli # this command can also be used if running from a TVM. Using sudo is MANDATORY so we don't touch the virtual environment!

During the installation of Trilio, you can enable observability to view logs directly in the UI instead of using the CLI. For detailed instructions, please refer to the Trilio Observability Integration documentation.
