Some considerations:

• Right now goreleaser generates a lot of package files, because it generates one for each architecture. We might want to limit those, amd64 and arm64 would probably be enough. (We still offer direct binary downloads for all architectures anyway)
• Packages are not signed yet. This causes a problem on alpine for example: ERROR: hcloud-cli_1.59.0_x86_64.apk: UNTRUSTED signature. We'd need to create a key and provide it to users so they can install it

The man pages have a 23-Jan-2026 Auto generated by spf13/cobra comment included. Is it possible to remove them, similar to how we are doing it for the markdown files?

cli/internal/scripts/generate_docs.go

Lines 52 to 72 in 097f2f0

	// Remove the 'Auto generated by...' lines at the bottom of files
	// This is done because this line contains the current date, which would create a diff when the file is re-generated
	generatedOnRegex := regexp.MustCompile(`\n###### Auto generated by spf13/cobra on .*\n`)
	for _, f := range files {
	if f.IsDir() {
	continue
	}
	path := filepath.Join(dir, f.Name())
	bytes, err := os.ReadFile(path)
	if err != nil {
	return fmt.Errorf("could not read file at %q: %w", path, err)
	}
	bytes = generatedOnRegex.ReplaceAll(bytes, nil)
	// We do this to wrap tables in a code block. Otherwise, they won't be displayed properly in markdown viewers.
	bytes = []byte(strings.ReplaceAll(string(bytes), "┌", "```\n┌"))
	bytes = []byte(strings.ReplaceAll(string(bytes), "┘", "┘\n```"))
	err = os.WriteFile(path, bytes, f.Type())
	if err != nil {
	return fmt.Errorf("could not write file at %q: %w", path, err)
	}
	}

Additionally, could you have a look at the table output in man hcloud-config? It is pretty wonky right now.

[phm07]

The manpage output (as well as the generated markdown docs) would have a way better table view if the tables are printed using markdown format. Our table renderer already supports this, we just need to find a way to switch between the pretty print and markdown. I used a custom config option for now but it doesn't seem to work, because viper is not loaded if you only generate docs/manpages. I'll have a look at this another time.
