Keepstore can store data in object storage compatible with the S3 API, such as Amazon S3, Google Cloud Storage, or Ceph RADOS.
-h2. Configure keepstore
-
-Copy the "access key" and "secret key" to files where they will be accessible to keepstore at startup time.
-
-<notextile>
-<pre><code>~$ <span class="userinput">sudo sh -c 'cat >/etc/arvados/keepstore/aws_s3_access_key.txt <<EOF'
-zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz==
-EOF</span>
-~$ <span class="userinput">sudo chmod 0400 /etc/arvados/keepstore/aws_s3_access_key.txt</span>
-</code></pre>
-</notextile>
-
-Next, edit the @Volumes@ section of the @keepstore.yml@ config file.
-
-h3. Example config for Amazon S3

- # storage.

- # The bucket to use for the backing store.

- UnsafeDelete: false
-</pre>
-
-Start (or restart) keepstore, and check its log file to confirm it is using the new configuration.
-
-h3. Example config for Google cloud storage
-
-See previous section for documentation of configuration fields.
-
-<pre>

-
-Start (or restart) keepstore, and check its log file to confirm it is using the new configuration.
