This article outlines basic server access details for artifactory.



 new artifactory at http://artifactory.errigal.com is run as a Nexus docker container via docker-compose.yml file, located at ''ubuntu@10.91.133.220:/home/ubuntu/docker/nexus/docker-compose.yml''
 <code>docker compose up -d</code>

 Stopped using <code>docker compose down</code>

 restarts are done via  <code>docker compose down; docker compose up</code>


**Location:**
  * The Artifactory server is hosted on our Waterford openstack.
**Access:**
  * The key for accessing this account can be found on dropbox in the following location: 
  * ssh to the server via ssh ubuntu@10.91.133.220





**URL:**

  * http://artifactory.errigal.com/


** Out of Space Issues **

If the nexus server drops below 4G you will see in the logs the DB has moved to read only

The only known approach so far is 

   * login to the docker container as root ** sudo docker exec -u 0 -it nexus /bin/bash
**
   * edit the **nexus.vmoptions** file located in **cd /opt/sonatype/nexus/bin/**
   * or **vi /opt/sonatype/nexus/bin/nexus.vmoptions**
   * add or uncomment the following line **-Dstorage.diskCache.diskFreeSpaceLimit=1024
**
   * exit docker bash
   * restart nexus **sudo docker restart nexus**
   * the Nexus is now in an editable state and artifacts can be removed in an effort to claim back space


===== Cheats approach =====

* edit file and remove # from last line
   * **sudo docker exec -u 0 -it nexus  vi /opt/sonatype/nexus/bin/nexus.vmoptions**
   * restart nexus **sudo docker restart nexus**


Once you have deleted number of artifacts, (start with largest first, to get going) you must run the **Compact Blob store** task to reduce space

   * Go to the tasks list under the Admin tab (you must be logged in)
   * run the Compact process, as its only set to weekly due to length of execution
   * This may affect the artifactory being written to (it has performance implications)
{{:development:2023-nexus-compact-blob-store.jpg?400|}}
   * on success run the **df -h** command and verify that the disk space is > 3G
      * **/dev/nvme0n1p1   60G   53G  7.5G  88% /**


===== Enable Admin Execute Script =====

Nexus allows the execution of groovy scripts on the repo, which is useful to find largest files etc

but this must be enabled

Reference [[https://support.sonatype.com/hc/en-us/articles/360045220393-Scripting-Nexus-Repository-Manager-3|Sonatype Support page]]

  * Edit $data-dir/etc/nexus.properties. 
  * Add the following on a new line, making sure the file is saved with an ending new line and with the original file permissions:
<WRAP center round box 60%>
nexus.scripts.allowCreation=true
</WRAP>
  * Restart NXRM to pick up the property change.


===== Configure Cleanup Policy =====

The artifactory needs to ensure that older redundant builds are periodically cleaned out, otherwise it will quickly fill up. SnmpManager is a large war file on its own.

To do this we use the Clean Up Policy Manager, example configuration deletes after 15 days
