talosctl bootstrap

Bootstrap the etcd cluster on the specified node.

Synopsis

When Talos cluster is created etcd service on control plane nodes enter the join loop waiting to join etcd peers from other control plane nodes. One node should be picked as the boostrap node. When boostrap command is issued, the node aborts join process and bootstraps etcd cluster as a single node cluster. Other control plane nodes will join etcd cluster once Kubernetes is boostrapped on the bootstrap node.

This command should not be used when “init” type node are used.

Talos etcd cluster can be recovered from a known snapshot with ‘–recover-from=’ flag.

  -h, --help                      help for bootstrap

talosctl completion

Output shell completion code for the specified shell (bash, fish or zsh)

Synopsis

Output shell completion code for the specified shell (bash, fish or zsh). The shell code must be evaluated to provide interactive completion of talosctl commands. This can be done by sourcing it from the .bash_profile.

Note for zsh users: [1] zsh completions are only supported in versions of zsh >= 5.2

talosctl completion SHELL [flags]

Examples

# Installing bash completion on macOS using homebrew
## If running Bash 3.2 included with macOS
	brew install bash-completion
## or, if running Bash 4.1+
	brew install bash-completion@2
## If talosctl is installed via homebrew, this should start working immediately.
## If you've installed via other means, you may need add the completion to your completion directory
	talosctl completion bash > $(brew --prefix)/etc/bash_completion.d/talosctl

# Installing bash completion on Linux
## If bash-completion is not installed on Linux, please install the 'bash-completion' package
## via your distribution's package manager.
## Load the talosctl completion code for bash into the current shell
	source <(talosctl completion bash)
## Write bash completion code to a file and source if from .bash_profile
	talosctl completion bash > ~/.talos/completion.bash.inc

talosctl copy

Copy data out from the node

Synopsis

Creates an .tar.gz archive at the node starting at and streams it back to the client.

Command doesn’t preserve ownership and access mode for the files in extract mode, while streamed .tar archive captures ownership and permission bits.
