    Vault password in domain mode (JBoss EAP 7)

    gfo44 Newbie

      Hi,

       

      I have a JBoss  EAP 7.0 in domain mode. I have a domain controller with several managed hosts.

      Considering that, I am trying to install "vault passwords".

       

      What I am currently doing (via Shell scripts):

      • create keystore + vault
      • put passwords in the vault
      • add the vault to the host configuration (via /host=<MYHOST>/core-service=vault:add)
      • add the vault to the host master configuration (via /host=master/core-service=vault:add)
        • => In the doc I didn't find any mention to that. Do we need to have vault conf in both hosts (domain controller and managed host) ?
      • push passwords to server groups, profiles, etc. (datasouces...)
      • try to start server-group
        • => I have a failure :

      /server-group=<MYSERVERGROUP>:start-servers

      {

          "outcome" => "failed",

          "failure-description" => {"host-failure-descriptions" => {"<MYHOST>" => "WFLYCTL0158: java.lang.SecurityException: WFLYSRV0228: security exception"}},

          "rolled-back" => true,

          "result" => {}

      }

        • I try to reload the configuration of my hosts as follow:

       

      /host=<MYHOST>:reload(use-current-host-config=true)

      /host=master:reload(use-current-host-config=true, use-current-domain-config=true)

       

        • after a while, my host <MYHOST> disepear in my domain controller (maybe because of the reload operation...) then nothing can work
          • => Do I need to reload my hosts to avoid "security exception"? If no, what can I do?

       

      Thanks a lot for your help.

      Regards

          Seems like vault misconfiguration. There are several similar posts out there.

           

          Search for exception in log. Try to mage working some simple example - e.g. vault in standalone mode. When you will ensure vault configuration is ok. Try to use one vault password in domain mode. (Yes you need vault configuration on all controllers)

            Hello,

            I still can't make it work.

             

            Can you please tell me if the following scenario seems good for you. Just an information before that, I am in domain mode. My master is installed and running. When I install my slaves, they push their configuration to the master. Then, for example, to install a slave, I need to run a bash script which will connect to the domain controller and execute JBoss command-line instruction.

             

            1/ During the installation of the domain controller, create the vault file.

            2/ Push the configuration to the domain controller (/host=master/core-service=vault:add[...])

            3/ During the installation of one of my slaves, create the vault file (a new one, not a duplication of the vault from the domain controller)

            4/ Push the configuration to the domain controller (/host=<MY SLAVE HOST>/core-service=vault:add[...])

            5/ Add passwords to my slaves vaults

            6/ Push passwords to my domain controller's vault (I run a bash script on my domain controller through a SSH connection, then my master keystore knows all the passwords and the slaves only passwords they need to know)

            7/ Push my vaults in my domain controller's configuration (for example: profile=SLAVE_PROFILE/subsystem=datasources/xa-data-source=MY_DS:write-attribute(name=password, value="${VAULT::vb::password::1}"))

            8/ I try to access my slave's app and I have this in logs:

            9/ I have read that we need to restart the domain controller because if we add vaults "on the fly", they are not loaded in memory: so I restart my domain controller

            10/ Here, nothing works: my slave host configuration is gone (I can't do /host=<MY SLAVE HOST> anymore)

             

            Thanks for your help.

            Regards
