Jenkins Pipleline using Groovy_Terraform plan job - sh

Question

I am creating a pipeline using jenkins, trying to add a logic where if the terraform-plan is successful then only it will proceed with apply, therefore need get the return value as 0/1/2 from the sh terraform plan command but getting an error as below:
+ gt
+ echo 2
2
C:/Users/Smi/.jenkins/workspace/Pipe_Groovy#tmp/durable-33bd46fb/script.sh: line 2: gt: command not found
+ status
C:/Users/Smi/.jenkins/workspace/Pipe_Groovy#tmp/durable-33bd46fb/script.sh: line 2: status: command not found
[Pipeline] }
Below is the code:
sh "terraform init"
sh "terraform get"
sh "set +e; terraform plan -out=plan.out -detailed-exitcode; echo \$? > status"
def exitCode = readFile('status').trim()
def apply = false
echo "Terraform Plan Exit Code: ${exitCode}"
if (exitCode == "0") {
currentBuild.result = 'SUCCESS'
}
if (exitCode == "1") {
slackSend channel: '#ci', color: '#0080ff', message: "Plan Failed: ${env.JOB_NAME} - ${env.BUILD_NUMBER} ()"
currentBuild.result = 'FAILURE'
}
if (exitCode == "2") {
stash name: "plan", includes: "plan.out"
slackSend channel: '#ci', color: 'good', message: "Plan Awaiting Approval: ${env.JOB_NAME} - ${env.BUILD_NUMBER} ()"
try {
input message: 'Apply Plan?', ok: 'Apply'
apply = true
} catch (err) {
slackSend channel: '#ci', color: 'warning', message: "Plan Discarded: ${env.JOB_NAME} - ${env.BUILD_NUMBER} ()"
apply = false
currentBuild.result = 'UNSTABLE'
}
}
Please advice

Answer 1

Shell is trying to find a command named gt and fails, so your job fails at this step. You probably wanted to use > instead.
There is a way to get the exit code of a bash command without redirecting it into a file and than reading it:
def status = sh(returnStatus: true, script: "set +e; terraform plan -out=plan.out -detailed-exitcode")

Do something as follows:
#!/bin/bash -xe
set +e
/terraform plan -var-file="${env}-custom.tfvars" -refresh=false -detailed-exitcode
PLAN_ECODE=$?
echo ${PLAN_ECODE}
set -e
if [ "${PLAN_ECODE}" -eq 1 ]; then
echo "ERROR!!! something is wrong planning!"
exit 1
elif [ "${PLAN_ECODE}" -eq 0 ]; then
echo "No changes!"
elif [ "${PLAN_ECODE}" -eq 2 ]; then
echo "Applying in progress!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
/terraform apply -auto-approve -var-file="${env}-custom.tfvars"
echo "$i has been updated (check logs above for details)" >> /tmp/logs.txt
fi
