Don’t use sing quotes ‘, make sure you use “, that way the string can be
interpolated.
I also use a global helper that grabs the output of `sh` functions.
def runAndReturn(script){
toReturn = sh(script:script, returnStdout: true)
toReturn = toReturn[0..-2]
println toReturn
toReturn
}
stage('Build image') {
steps {
tagBefore = runAndReturn("git describe --candidate=1 --tags")
tag = runAndReturn("echo ${tagBefore} | cut -d\'-\' -f 1")
webImageName =
"${env.ACR_LOGINSERVER}/my-project-1499882073260/test:${tag}"
sh "sudo docker build -t ${webImageName} -f
WebApplication/WebApplication1/Dockerfile WebApplication/."
}
}
or something like:
stage('Build image') {
steps {
sh """
export TAG=$(git describe --candidate=1 --tags)'
export TAG=$(echo $TAG | cut -d\'-\' -f 1)'
export
WEB_IMAGE_NAME=$ACR_LOGINSERVER/my-project-1499882073260/test:$TAG
sudo docker build -t $WEB_IMAGE_NAME -f
WebApplication/WebApplication1/Dockerfile WebApplication/.
"""
}
}
First example would allow you to go through and get access to strings to have
more control over the strings. Second is an example of how you could use it to
stay in bash.
