Using literal variables in a Wildfly OFFLINE CLI

[reisub83]

I'd like to use an offline Wildfly CLI to add system properties

The problem is that the value should be a variable

This is the desired result:

        <property name="user.country" value="${country}"/> 

the problem is that the CLI try to resolve the variable

[disconnected /] embed-server [standalone@embedded /] /system-property=user.country:add(value="${country}") { "outcome" => "failed", "failure-description" => "WFLYCTL0211: Cannot resolve expression '${country}'", "rolled-back" => true } 

I tried to escape the '$' with '$$' or '\$', but it doesn't worked.

Or rather, with '$$' I got

<property name="user.language" value="$${countrylowercase}"/> 

If I run the server an retry with a connect CLI , it works normally, because the resolve-parameter-values is false in jboss-cli.xml

How to do this offline?

As a workaround I'm doing a sed on the resultef standalone to replace '$${' with '${'  , but I don't like it too much...

Thanks

You can use cli scripting like described here JBoss EAP 6 : using variables in CLI scripts (jboss-cli.sh) - Red Hat Customer Portal

[reisub83]

Sorry, I can't access that link

This page describes 2 approaches.

     1. via properties

• Use the "--properties=/path/to/file.properties" to pass in the properties.

               Example: myvar=value

• The notation in the CLI script is then as per usual "${myvar}"

               Example: /subsystem=datasources/xa-data-source=MyDS/statistics=pool:read-resource(include-runtime=${myvar})

     2. via bash scripting

• Example:

     #!/bin/bash

     PASSWORD=secret

     KEYFILE=ourKeyFileName

     FQHN=host.domain.com

     $JBOSS_HOME/bin/jboss-cli.sh --connect <<EOF

          batch

               /subsystem=web/connector=https:add(secure=true,name=https,socketbinding=https,scheme=https,protocol="HTTP/1.1")

               /subsystem=web/connector=https/ssl=configuration:add(name=ssl,password="$PASSWORD",certificate-keyfile="\${jboss.server.config.dir}/$KEYFILE.jks",key-alias="$FQHN")

          run-batch

          exit

     EOF

Thanks

actually the properties file is my approach, this is what I'm running

${WILDFLY_HOME}/bin/jboss-cli.sh -Djboss.server.base.dir=/home/user/server/basedir --file=/home/user/properties.cli

and in the .cli file

embed-server

/system-property=user.language:add(value="${countrylowercase}")
/system-property=user.region:add(value="${country}")
/system-property=user.country:add(value="${country}")


stop-embedded-server

But I've also tried the inline mode in a bash script , same results, the cli tried to resolve the variables

[mayerw01]

Your file contain cli commands. But as mentioned above you should first create a properties file like

country=Amerika

countrylowercase=amerika

You should then provide this flle to the jboss-cli

like

${WILDFLY_HOME}/bin/jboss-cli.sh -Djboss.server.base.dir=/home/user/server/basedir --file=/home/user/commands.cli  --properties=/home/user/properties.cli

[reisub83]

But this is not what I want to achieve...

This is how the standalone should results:

...   

</extensions>

<system-properties>

     <property name="file.encoding" value="UTF-8"/>

     <property name="user.language" value="${countrylowercase}"/>

     <property name="user.region" value="${country}"/>

     <property name="user.country" value="${country}"/>

</system-properties>

<management>

...

[mayerw01]

So why don't you just set uo your properties file like

country=$country

countrylowercase=$countrylowercase

[reisub83]

Already tried, same result : "Cannot resolve expression"

[mayerw01]

At least in my environment this is working as expected.

cat cli.commands

    embed-server 

    /system-property=user.language:add(value="${countrylowercase}") 

    /system-property=user.region:add(value="${country}") 

    /system-property=user.country:add(value="${country}") 

    stop-embedded-server 

cat cli.property

country=$country

countrylowercase=$countrylowercase

$JBOSS_HOME/bin/jboss-cli.sh --properties=./cli.property --file=./cli.commands

{"outcome" => "success"}

{"outcome" => "success"}

{"outcome" => "success"}

what is your WildFly version and where do you get this error message?

[reisub83]

Now I begin to understand.

What I tried is different but I just assumed it was idempotent:

I had set the variables directly in the cli script:

    embed-server

    set country=${country}

    set countrylowercase=${countrylowercase}

    /system-property=user.language:add(value="${countrylowercase}")

    /system-property=user.region:add(value="${country}")

    /system-property=user.country:add(value="${country}")

    stop-embedded-server

I need to try with the dedicated properties file

[reisub83]

# cat variables.cli

country=${country}

countrylowercase=${countrylowercase}

# cat properties.cli

embed-server

/system-property=user.language:add(value="${countrylowercase}")

/system-property=user.region:add(value="${country}")

/system-property=user.country:add(value="${country}")

stop-embedded-server

${WILDFLY_HOME}/bin/jboss-cli.sh -Djboss.server.base.dir=/home/user/server/base/ --properties=/home/user/variables.cli --file=/home/user/properties.cli

Running properties.cli

{

    "outcome" => "failed",

    "failure-description" => "WFLYCTL0211: Cannot resolve expression '${countrylowercase}'",

    "rolled-back" => true

}

this is a Wildfly 18

[reisub83]

Ok so

this is not working

# cat variables.cli

country=${country}

countrylowercase=${countrylowercase}

this is working

cat cli.property

country=$country

countrylowercase=$countrylowercase

thanks for your help and your time!
