- use Println to print newline instead of custom format - use apiClient instead of client for the API client to prevent shadowing imports. - use dockerCLI with Go's standard camelCase casing. - suppress some errors to make my IDE and linters happier - fix some tests to work with "go test -update" - rewrite TestSwarmInit to use sub-tests Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
