I am new to both GITLAB and GATLING. I am trying to implement shift-left performance testing as part of CI/CD pipeline using the mentioned tool. Although I am very proficient with Jenkins and Jmeter. I am trying to write Gitlab Pipeline ID to gatling simulation log file.

I have referred to the GITLAB variable and $CI_PIPELINE_IID is used to expose the pipeline execution ID. In case of scala I can fetch or infuse environment variables using JAVA_OPTS but not able to fetch the gitlab pipeline id.

I did some further research and i was able to print the pipeline ID on the Gitlab Console

$ echo $CI_PIPELINE_ID
141683

Further I read as part of scala[Gitlab], CI variables can be used as ENV variables during the build, so retrieving them as
System.getEnv("$CI_PIPELINE_IID")

But while i try the same I get null value.

val varPipelineId = System.getenv("$CI_PIPELINE_ID")
println(varPipelineId)

Console log:

$ echo $CI_PIPELINE_ID
141694
$ mkdir /opt/gatling/user-files/simulations/cloudnative/
$ cp gatling-reports/cloudnativems.scala /opt/gatling/user-files/simulations/cloudnative/
$ /opt/gatling/bin/gatling.sh -s cloudnative.cloudnativems
GATLING_HOME is set to /opt/gatling
null

Second Part of the requirement:
I want to write the value of pipeline id in gatling simulation.log file with each log entry

Actual format of simulation.log

Modified format of simulation.log

REQUEST 1 account_movement_post 1553663401413 1553663404218 KO status.find.in(200,201,202,203,204,205,206,207,208,209,303), found 500 [pipeline_id]

I made a logical change - removed $ from the environment variable

val varPipelineId = System.getenv("CI_PIPELINE_ID")
println(varPipelineId)

Output:

 $ echo $CI_PIPELINE_ID
 141714
 $ mkdir /opt/gatling/user-files/simulations/cloudnative/
 $ cp gatling-reports/cloudnativems.scala /opt/gatling/user-files/simulations/cloudnative/
 $ /opt/gatling/bin/gatling.sh -s cloudnative.cloudnativems
 GATLING_HOME is set to /opt/gatling
