| <p>To access an S3 bucket, users need AWS access key ID and AWS secret. Both of |
| these are generated by going to AWS website. When you use Ozone’s S3 |
| protocol, you need the same AWS access key and secret.</p> |
| <p>Under Ozone, the clients can download the access key directly from Ozone. |
| The user needs to <code>kinit</code> first and once they have authenticated via kerberos |
| they can download the S3 access key ID and AWS secret. Just like AWS S3, |
| both of these are secrets that needs to be protected by the client since it |
| gives full access to the S3 buckets.</p> |
| <ul> |
| <li>S3 clients can get the secret access id and user secret from OzoneManager.</li> |
| </ul> |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">ozone s3 getsecret |
| </code></pre></div><p>This command will talk to ozone, validate the user via Kerberos and generate |
| the AWS credentials. The values will be printed out on the screen. You can |
| set these values up in your <em>.aws</em> file for automatic access while working |
| against Ozone S3 buckets.</p> |
| <div class="alert alert-danger" role="alert"> |
| Please note: These S3 credentials are like your Kerberos passwords |
| that give complete access to your buckets. |
| </div> |
| <ul> |
| <li>Now you can proceed to setup these secrets in aws configs:</li> |
| </ul> |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">aws configure set default.s3.signature_version s3v4 |
