Concatenate values to properties in YAML config

[tdferreira]

Hello,

It would be very useful if we could concatenate any value before or after any property placeholder.

For example, if I want to use a fixed server port number prefix and always keep the last number, I would like to be able to do this:

ListenPort: '@@PROP:Server.Port.Prefix@@2'

Or even concatenate multiple properties:

ListenPort: '@@PROP:Server.Port.Prefix@@@@PROP:MyServer.Port@@'

Currently I get this error:

SEVERE Messages:

    1. WLSDPLY-12409: createDomain failed to create the domain: Failed to set attribute ListenPort in path /Server/MyServer to value 75,300: 60922: Invalid port value.

60922: The listen port value 75300 of Server "MyServer" is out of range. It must be between 1 and 65535.
60922: Enter a valid port value.

Would it be possible for you to implement this?

@tdferreira The variable substitution capability you are requesting already exists. The error seems to be because the ListenPort value you have constructed is out of the valid port ranges...not because the variable substitution is not working.

Here is my model:

domainInfo:
    AdminUserName: 'web@@PROP:prop1@@ic'
    AdminPassword: '@@PROP:pass1@@@@PROP:pass2@@'
topology:
    Name: mydomain
    Server:
        AdminServer:
            ListenPort: '7@@PROP:digit2@@@@PROP:digit3@@1'

and here is my variables file:

prop1=log
pass1=wel
pass2=come1
digit2=8
digit3=9

Create Domain works fine:

Issue Log for createDomain version 4.0.0-SNAPSHOT running WebLogic version 12.2.1.4.0.231010 in offline mode:

Total:   SEVERE :    0  WARNING :    0

createDomain.sh completed successfully (exit code = 0)

The resulting config.xml shows that the ListenPort is being properly substituted:

  <server>
    <name>AdminServer</name>
    <listen-port>7891</listen-port>
    <listen-address/>
    <server-life-cycle-timeout-val>30</server-life-cycle-timeout-val>
    <startup-timeout>0</startup-timeout>
  </server>

If I start the resulting domain, I am able to log into the Console using my constructed username and password.

You're absolutely right, the error message was quite clear about that and I just didn't read it properly.
Thank you for the thorough explanation ;)
