 ====== Sonatype NEXUS ====== ====== Sonatype NEXUS ======

 +Latest version on dockerhub: [[https://hub.docker.com/r/sonatype/nexus3/tags|sonatype/nexus3]]
  
 ===== Issues ===== ===== Issues =====
  
 +===== docker: convert to H2 database =====
 +
 +Based on advice [[https://github.com/sonatype/nexus-public/issues/451#issuecomment-2295431367|Nexus migration for OrientDB to H2 for 3.70.1-02 fails as nexus-db-migrator is version 3.70.1-03 #451]]:
 +
 +  * Update docker image to tag: to 3.70.2.
 +  * Create backup task for OrientDB and run it:
 +    * Nexus --> create task --> type: ''Admin - Export databases for backup''
 +      * taskname: ''backup''
 +      * backup location: ''/nexus-data/backup''
 +  * shutdown nexus ''docker compose stop''
 +  * edit default command line to start container without running Nexus:
 +<file yaml docker-compose.yml>
 +services:
 +  nexus3:
 +    image: sonatype/nexus3:3.70.2
 +    container_name: nexus3
 +    command: "sleep 3600"
 +</file>    
 +  * Start container ''docker compose up -d''
 +  * Login into container: ''docker-compose exec nexus3 /bin/bash''
 +  * ''cd /nexus-data/backup''
 +  * Check if four backup files exists in ''nexus-data/backup''. Mine was created under subfolder name ''/'' (slash) ???. So I moved it to correct location.
 +  * ''curl -s -L -O https://download.sonatype.com/nexus/nxrm3-migrator/nexus-db-migrator-3.70.1-03.jar''
 +  * ''java -Xmx2G -Xms2G -XX:+UseG1GC -XX:MaxDirectMemorySize=28672M -jar nexus-db-migrator-3.70.1-03.jar --migration_type=h2''
 +  * ''cp nexus.mv.db /nexus-data/db''
 +  * ''vi /nexus-data/etc/nexus.properties'' and add/change: ''nexus.datastore.enabled=true'' and save.
 +  * exit from container (CTRL+D)
 +  * stop container ''docker compose stop''
 +  * remove ''command'' from ''docker-compose.yml''
 +  * run again Nexus 3.70.2: ''docker compose up -d''
 +  * check if H2 database is used: ''docker compose logs | grep H2''
 +  * stop, update Nexus to 3.71.0 and start

 +**Reason**: Due to bug [[https://issues.sonatype.org/browse/NEXUS-28078|Docker - Delete unused manifests and images task may delete referenced layers if the database query to select components encounters limits]], docker blobs were removed.
 +
 +**Solution**: redeploy image again.
