transfer-helper

Simple one-shot provisioning script for a fresh Ubuntu 22.04 (root) environment. Installs Docker Engine, kubectl, doctl, linode-cli, boto3, Oh My Zsh, and supporting CLI tools. Also generates an Ed25519 SSH key and prints its public part.

Quick Start (run as root)

curl -fsSL https://raw.githubusercontent.com/valiot/transfer-helper/refs/heads/main/install.sh | bash

If you are not root, prepend sudo:

curl -fsSL https://raw.githubusercontent.com/valiot/transfer-helper/refs/heads/main/install.sh | sudo bash

What It Does

• Updates and upgrades existing apt packages
• Installs: zsh, mosh, postgresql-client, ruby, git, jq, pipx, python tooling
• Removes legacy Docker-related packages, adds Docker’s official repo, installs Docker Engine + Buildx + Compose plugin
• Installs kubectl (latest stable)
• Installs DigitalOcean doctl (via snap if available, else tarball) and connects common interfaces
• Installs linode-cli and boto3 via pipx
• Installs Oh My Zsh (non-interactive) and sets zsh as default shell for root
• Adds a helper function lke-save to merge Linode LKE kubeconfigs
• Creates ~/.kube and ensures secure permissions
• Generates an Ed25519 SSH key at /root/.ssh/id_ed25519 if absent and prints the public key
• Provides a summary of versions at the end

Idempotency

Re-running the script is safe: it skips steps already completed (e.g., existing Docker keyring, kubectl, doctl, Oh My Zsh, SSH key, and lke-save function).

After Installation

• Start a new shell or run: exec zsh
• Copy the printed public SSH key to any services that require it
• Use lke-save <cluster-label> to merge an LKE cluster kubeconfig into your main kubeconfig

Notes

• Script assumes Ubuntu 22.04; a warning is shown if a different version is detected.
• Must run as root (or via sudo) because it installs system packages and modifies root’s shell.
