3. iSCSI RPC RPC Jiva BackEnd Container Jiva FrontEnd Node Node Node Jiva BackEnd Container bitbucket UseCase of OpenEBS Jiva
4. How to get Jiva Image ? Use “docker search openebs/jiva” $ docker search openebs/jiva NAME DESCRIPTION STARS openebs/jiva OpenEBS is purpose built storage for conta... 3 openebs/jiva-ci jiva images generated by Travis CI 0
5. Pull the jiva Image ? $ docker pull openebs/jiva Using default tag: latest latest: Pulling from openebs/jiva Digest: sha256:71c59687b59e6dc7b454817c94fd4a9069e01f7b1780c7257931edacd7dff2c Status: Image is up to date for openebs/jiva:latest
6. Jiva Front End Container $docker run -d --network="host" -P --expose 3260 --expose 9501 \ openebs/jiva launch controller \ --frontend gotgt --frontendIP 172.31.28.114 vol1 10G
7. Jiva Backend Container Creation $ docker run -d --network="host" -P --expose 9502-9504 \ --expose 9700-9800 -v /mnt/store1:/store1 \ openebs/jiva launch replica --frontendIP 172.31.28.114 \ --listen 172.31.45.197:9502 --size 10G /store1 $ mkdir /mnt/store1
8. 3260 - iscsi target listener at the frontend 9501 - frontend is listening for management commands. 9502 - backends are listening for management commands. 9503 - backends are listening for a connection from frontend for data transfer. 9504 - backends are listening for data sync initiation with other backends when the backend comes up. 9700-9800 - sync threads while syncing data Ports used by Jiva frontend and backend
9. curl http://<frontend IP>:9501/v1/replicas Check the health of jiva Monitor data is synced in all backend ? curl http://<Replica IP>:9502/v1/stats
10. iSCSI Initiator Install $sudo apt install open-iscsi $iscsiadm -m discovery -t st -p 192.168.0.10 Check for the target $iscsiadm -m node -T \ "iqn.2016-09.com.openebs.jiva:vol" \ -p "172.31.28.114:3260" --login Login to the iSCSI target iSCSI Initiator Setp
11. Attach volume to the Bitbucket container $docker run -d -v /bitbucket:/var/atlassian/application-data/bitbucket \ -p 7990:7990 -p 7999:7999 \ atlassian/bitbucket-server
