856 | <title>Machine and Image Names</title> | |
857 | ||
858 | <para>The <command>machinectl</command> tool operates on machines | |
b938cb90 | 859 | and images whose names must be chosen following strict |
91913f58 LP |
860 | rules. Machine names must be suitable for use as host names |
861 | following a conservative subset of DNS and UNIX/Linux | |
862 | semantics. Specifically, they must consist of one or more | |
863 | non-empty label strings, separated by dots. No leading or trailing | |
864 | dots are allowed. No sequences of multiple dots are allowed. The | |
a8eaaee7 | 865 | label strings may only consist of alphanumeric characters as well |
91913f58 LP |
866 | as the dash and underscore. The maximum length of a machine name |
867 | is 64 characters.</para> | |
868 | ||
869 | <para>A special machine with the name <literal>.host</literal> | |
870 | refers to the running host system itself. This is useful for execution | |
a8eaaee7 | 871 | operations or inspecting the host system as well. Note that |
91913f58 LP |
872 | <command>machinectl list</command> will not show this special |
873 | machine unless the <option>--all</option> switch is specified.</para> | |
874 | ||
a8eaaee7 | 875 | <para>Requirements on image names are less strict, however, they must be |
91913f58 LP |
876 | valid UTF-8, must be suitable as file names (hence not be the |
877 | single or double dot, and not include a slash), and may not | |
878 | contain control characters. Since many operations search for an | |
b938cb90 | 879 | image by the name of a requested machine, it is recommended to name |
91913f58 LP |
880 | images in the same strict fashion as machines.</para> |
881 | ||
882 | <para>A special image with the name <literal>.host</literal> | |
a8eaaee7 | 883 | refers to the image of the running host system. It hence |
91913f58 LP |
884 | conceptually maps to the special <literal>.host</literal> machine |
885 | name described above. Note that <command>machinectl | |
7ca41557 | 886 | list-images</command> will not show this special image either, unless |
91913f58 LP |
887 | <option>--all</option> is specified.</para> |
