swh-objstorage

Content-addressable object storage for the Software Heritage project.

Quick start

The easiest way to try the swh-objstorage object storage is to install it in a virtualenv. Here, we will be using https://virtualenvwrapper.readthedocs.io_ but any virtual env tool should work the same.

In the example below we will create a new objstorage using the https://docs.softwareheritage.org/devel/apidoc/swh.objstorage.html#module-swh.objstorage.objstorage_pathslicing backend.

~/swh$ mkvirtualenv -p /usr/bin/python3 -i swh.objstorage swh-objstorage
[...]
(swh-objstorage) ~/swh$ cat >local.yml <<EOF
objstorage:
  cls: pathslicing
  args:
    root: /tmp/objstorage
    slicing: 0:2/2:4/4:6
EOF
(swh-objstorage) ~/swh$ mkdir /tmp/objstorage
(swh-objstorage) ~/swh$ swh-objstorage -C local.yml serve -p 15003
INFO:swh.core.config:Loading config file local.yml
======== Running on http://0.0.0.0:15003 ========
(Press CTRL+C to quit)

Now we have an API listening on http://0.0.0.0:15003 we can use to store and retrieve objects from. I an other terminal:

~/swh$ workon swh-objstorage
(swh-objstorage) ~/swh$ cat >remote.yml <<EOF
objstorage:
  cls: remote
  args:
    url: http://127.0.0.1:15003
EOF
(swh-objstorage) ~/swh$ swh-objstorage -C remote.yml import .
INFO:swh.core.config:Loading config file remote.yml
