          Description

          Dear,

          You could try to setup a cloud-init script with specific configuration for your instance. Here you have an example: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/4/html/End_User_Guide/user-data.html on how to write it.

          You should be able to inject the configuration to your instance from the section under tab “4. Post-Creation” in the instance launch window.

          Best,
          Daniele

It seems that when you do it in this way, the cloud environment sets the hostname automatically with a name based on the image name itself. Later, when I try to modify the hostname following the CentOS typical procedures (hostnames file, hostname command, etc) the image seems to do it correctly but if I reboot the machine the hostname is reverted to the original one. ¿How could I prevent this to happen?.

            I’m 99% sure you can’t modify the cloud-init script already associated with an instance from the UI. An idea could be to see in the vm this folder (if present): /etc/cloud/, probably you can modify some scripts from there. Also be aware that the cloud-init script is started with an upstart job present in /etc/init.d/cloud-init*.

            Anyway, my suggestion is: try to create a snapshot of your instance and then boot up a new instance from the image/snapshot previously created. Before booting the image you can configure your cloud-init script from the UI.

            Best,
            Daniele

            Thanks Daniele,

            Does it mean that I can only do that when creating the instance? Is there
            any procedure to modify it once created?.

            Dear,

            You could try to setup a cloud-init script with specific configuration for
            your instance. Here you have an example:
            https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenS
            tack_Platform/4/html/End_User_Guide/user-data.html on how to write it.

            You should be able to inject the configuration to your instance from the
            section under tab “4. Post-Creation” in the instance launch window.

            Best,

            launched on the Lab.
            launched an instance of a CentOS 6.5 based image. It seems that when you do
            it in this way, the cloud environment sets the hostname automatically with
            a name based on the image name itself. Later, when I try to modify the
            hostname following the CentOS typical procedures (hostnames file, hostname
            command, etc) the image seems to do it correctly but if I reboot the machine
            the hostname is reverted to the original one. ¿How could I prevent this to
            happen?.
