Version

Current Version: 0.1.0

Hardware Requirements

CPU

  • No stats avaible to say the number of core that you need for the size of your storage

Memory

  • No stats avaible to say the memory that you need for the size of your storage
  • I think add some guster option to allow the setting some cache on memory

Storage

The storage determine the size of your potential volume. It's depend of the number of volume and the number of replica.
If you create many volume, and you should that volume can't take more space, you can use environment varibale "GLUSTER_QUOTA".
By default, all data are store on '/data'. So it's good idea to add volume on it. You can also setting this with 'GLUSTER_DATA' environment variable.

Main section

  • NAME : Put 'gluster' as a name of your service. If you change this name, you must add environment variable name SERVICE_NAME with the name of your current service.
  • SCALE: Run 2 or more container. I think you can start with 2 and upgrade later with 4 if needed
  • SELECT IMAGE : put 'webcenter/rancher-glusterfs-server:latest'

ADVANCED OPTIONS - Command

    • SERVICE_NAME : it' the name of you service. By default it's 'gluster'
    • GLUSTER_DATA : It's path to store glusterfs data. By default it's '/data'
    • GLUSTER_VOLUMES : It's the list of volume you need to host on the glusterfs (for exemple : 'dbvol,appvol'). By default it's 'ranchervol'.
    • GLUSTER_TRANSPORT : It's the transport on glusterfs. By default it's 'tcp'.
    • GLUSTER_REPLICA : It's the number of replica for your data hosted on gluster. By default it's '2'.
    • GLUSTER_STRIPE : It's the stripe of your volume . By default it's disable.
    • GLUSTER_QUOTA : It's the quota size for your each volume (for exemple '10GB'): By default it's disable.

ADVANCED OPTIONS - Volumes

  • VOLUMES : Put '/data' on your host. For exemple : '/data/MY_STACK:/data'

ADVANCED OPTIONS - Security/Host

  • CAPABILITIES : Add 'SYS_ADMIN'. It's needed lauchn glusterfs
  • DEVICE BINDING : Put '/dev/fuse'. It's needed by glusterfs (for exemple if you use quota)

ADVANCED OPTIONS - Scheduling

  • Add scheduling with the following rules : 'The host must not have a service with the name 'MY_STACK/gluster'. This rules permit to lauchn a unique container gluster of this stack on each host (it's better to avoid SPOF).
