Using the CLI with Docker

The CLI can be used in Docker without any problem.

Basic usage

In order to use it you must mount the scaleway configuration file:

docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0

If you want to use scw instead of docker run you can add the following in your ~/.bashrc:

scw() {
    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 "$@"
}
export -f scw

Or if you use ZSH, add the following in your ~/.zshrc:

scw() {
    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 $@
}

Autocompletion

You can still use autocompletion while running the CLI in Docker, you just need to modify script generated by the CLI. For instance, scw autocomplete script shell=bash will return:

_scw() {
	_get_comp_words_by_ref -n = cword words

	output=$(scw autocomplete complete bash -- "$COMP_LINE" "$cword" "${words[@]}")
	COMPREPLY=($output)
	# apply compopt option and ignore failure for older bash versions
	[[ $COMPREPLY == *= ]] && compopt -o nospace 2> /dev/null || true
	return
}
complete -F _scw scw

And in your ~/.bashrc you can add:

scw() {
    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 "$@"
}
export -f scw

_scw() {
	_get_comp_words_by_ref -n = cword words

	output=$(docker run -i --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 autocomplete complete bash -- "$COMP_LINE" "$cword" "${words[@]}")
	COMPREPLY=($output)
	# apply compopt option and ignore failure for older bash versions
	[[ $COMPREPLY == *= ]] && compopt -o nospace 2> /dev/null || true
	return
}
complete -F _scw scw

The trick is to remove the -t when using docker inside the completion function.
