Spack has support for this with *mirrors*. A -mirror is a URL that points to a directory, either on the local -filesystem or on some server, containing tarballs for all of Spack's -packages. - -Here's an example of a mirror's directory structure:: - - mirror/ - cmake/ - cmake-2.8.10.2.tar.gz - dyninst/ - DyninstAPI-8.1.1.tgz - DyninstAPI-8.1.2.tgz - libdwarf/ - libdwarf-20130126.tar.gz - libdwarf-20130207.tar.gz - libdwarf-20130729.tar.gz - libelf/ - libelf-0.8.12.tar.gz - libelf-0.8.13.tar.gz - libunwind/ - libunwind-1.1.tar.gz - mpich/ - mpich-3.0.4.tar.gz - mvapich2/ - mvapich2-1.9.tgz - -The structure is very simple. There is a top-level directory. The -second level directories are named after packages, and the third level -contains tarballs for each package, named as they were in the -package's fetch URL. - -``spack mirror`` -~~~~~~~~~~~~~~~~~~~~~~~ - -Mirrors are managed with the ``spack mirror`` command. The help for -``spack mirror`` looks like this:: - - $ spack mirror -h - usage: spack mirror [-h] SUBCOMMAND ... - - positional arguments: - SUBCOMMAND - create Create a directory to be used as a spack mirror, and fill - it with package archives. - add Add a mirror to Spack. - remove Remove a mirror by name. - list Print out available mirrors to the console. - - optional arguments: - -h, --help show this help message and exit - -The ``create`` command actually builds a mirror by fetching all of its -packages from the internet and checksumming them. - -The other three commands are for managing mirror configuration. They -control the URL(s) from which Spack downloads its packages. - - -``spack mirror create`` -~~~~~~~~~~~~~~~~~~~~~~~ - -You can create a mirror using the ``spack mirror create`` command, assuming -you're on a machine where you can access the internet. - -The command will iterate through all of Spack's packages and download -the safe ones into a directory structure like the one above. Here is -what it looks like: - - -.. code-block:: bash - - $ spack mirror create libelf libdwarf - ==> Created new mirror in spack-mirror-2014-06-24 - ==> Trying to fetch from http://www.mr511.de/software/libelf-0.8.13.tar.gz - ########################################################## 81.6% - ==> Checksum passed for libelf@0.8.13 - ==> Added spack-mirror-2014-06-24/libelf/libelf-0.8.13.tar.gz to mirror - ==> Trying to fetch from http://www.mr511.de/software/libelf-0.8.12.tar.gz - ###################################################################### 98.6% - ==> Checksum passed for libelf@0.8.12 - ==> Added spack-mirror-2014-06-24/libelf/libelf-0.8.12.tar.gz to mirror - ==> Trying to fetch from http://www.prevanders.net/libdwarf-20130207.tar.gz - ###################################################################### 97.3% - ==> Checksum passed for libdwarf@20130207 - ==> Added spack-mirror-2014-06-24/libdwarf/libdwarf-20130207.tar.gz to mirror - ==> Trying to fetch from http://www.prevanders.net/libdwarf-20130126.tar.gz - ######################################################## 78.9% - ==> Checksum passed for libdwarf@20130126 - ==> Added spack-mirror-2014-06-24/libdwarf/libdwarf-20130126.tar.gz to mirror - ==> Trying to fetch from http://www.prevanders.net/libdwarf-20130729.tar.gz - ############################################################# 84.7% - ==> Checksum passed for libdwarf@20130729 - ==> Added spack-mirror-2014-06-24/libdwarf/libdwarf-20130729.tar.gz to mirror - -Once this is done, you can tar up the ``spack-mirror-2014-06-24`` directory and -copy it over to the machine you want it hosted on. - -Custom package sets -^^^^^^^^^^^^^^^^^^^^^^^^ - -Normally, ``spack mirror create`` downloads all the archives it has -checksums for. If you want to only create a mirror for a subset of -packages, you can do that by supplying a list of package specs on the -command line after ``spack mirror create``. For example, this -command:: - - $ spack mirror create libelf@0.8.12: boost@1.44: - -Will create a mirror for libelf versions greater than or equal to -0.8.12 and boost versions greater than or equal to 1.44. - -Mirror files -^^^^^^^^^^^^^^^^^^^^^^^^ - -If you have a *very* large number of packages you want to mirror, you -can supply a file with specs in it, one per line:: - - $ cat specs.txt - libdwarf - libelf@0.8.12: - boost@1.44: - boost@1.39.0 - ... - $ spack mirror create -f specs.txt - ... - -This is useful if there is a specific suite of software managed by -your site. - - -``spack mirror add`` -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Once you have a mirrror, you need to let spack know about it. This is -relatively simple. First, figure out the URL for the mirror. If it's -a file, you can use a file URL like this one:: - - file:///Users/gamblin2/spack-mirror-2014-06-24 - -That points to the directory on the local filesystem. If it were on a -web server, you could use a URL like this one: - - https://example.com/some/web-hosted/directory/spack-mirror-2014-06-24 - -Spack will use the URL as the root for all of the packages it fetches. -You can tell your Spack installation to use that mirror like this: - -.. code-block:: bash - - $ spack mirror add local_filesystem file:///Users/gamblin2/spack-mirror-2014-06-24 - -Each mirror has a name so that you can refer to it again later. - -``spack mirror list`` -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If you want to see all the mirrors Spack knows about you can run ``spack mirror list``:: - - $ spack mirror list - local_filesystem file:///Users/gamblin2/spack-mirror-2014-06-24 - -``spack mirror remove`` -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -And, if you want to remove a mirror, just remove it by name:: - - $ spack mirror remove local_filesystem - $ spack mirror list - ==> No mirrors configured. - -Mirror precedence -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Adding a mirror really just adds a section in ``~/.spackconfig``:: - - [mirror "local_filesystem"] - url = file:///Users/gamblin2/spack-mirror-2014-06-24 - [mirror "remote_server"] - url = https://example.com/some/web-hosted/directory/spack-mirror-2014-06-24 - -If you want to change the order in which mirrors are searched for -packages, you can edit this file and reorder the sections. Spack will -search the topmost mirror first and the bottom-most mirror last. - - .. _temp-space: Temporary space |
