kubectl copying and transfering file to a pod without tar installed

In general we would have tar installed on a kubernetes pod. Sometimes when things are not happening, we can still copy to the container using the following command :-  Copy to container cat local-backup.tar.gz | kubectl exec -i -n cattle-resources-system \ rancher-backup-57c997f8cd-fxlb4 -c rancher-backup -- \ sh -c 'cat > /var/lib/backups/backup.tar.gz' Copying from container  kubectl exec -n cattle-resources-system rancher-backup-84576c498c-lpjh2 \ -c rancher-backup -- cat /var/lib/backups/default-location-recurring-backup-8723b2bd-e272-430e-89f6-14a133f8a417-2026-02-25T03-12-05Z.tar.gz \ > local-backup.tar.gz

qwen code - error installing

Image
When installing qwen code using the following command  curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.sh | bash  it stuck in endless loop. This is due to installer not having permission to the /usr folder. To resolve it # 1. Create the directory for global packages mkdir -p ~/.npm-global # 2. Tell npm to use this new directory npm config set prefix '~/.npm-global' # 3. Open (or create) your shell profile file # If you use Bash (default on many Linux): echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc source ~/.bashrc Install gwen  npm install -g @qwen-code/qwen-code@latest And walla!
