Jenkinsfile docker exec error executable file not found in $PATH while running ruby tests - ruby

Question

I have a stage in Jenkinsfile to run some ruby test files using rake test. But the tests are taking too long, so I am planning to implement the parallel running of individual tests. But I am getting an error while executing individual tests in parallel stages.
All the test cases are ran using rake test when we are in lib folder.
Individual test cases are ran using ruby test1.rb when we are in lib/test folder.
Currently working Jenkinsfile :
stage('Test Image') {
steps {
script {
sh "docker run --rm --entrypoint '' -v \${AWS_CONFIG_FILE:-/home/ubuntu/.aws/config}:/root/.aws/config:ro -v \${AWS_SHARED_CREDENTIALS_FILE:-/home/ubuntu/.aws/credentials}:/root/.aws/credentials:ro -v ${WORKSPACE}/test-results:/srv/www/lib/test/html_reports ${IMAGE_NAME} rake test"
}
}
}
Modified Jenkinsfile with Parallel tests:
stage('Test the Image') {
parallel {
stage('Test1'){
steps {
script {
sh "docker run --rm --entrypoint '' -v \${AWS_CONFIG_FILE:-/home/ubuntu/.aws/config}:/root/.aws/config:ro -v \${AWS_SHARED_CREDENTIALS_FILE:-/home/ubuntu/.aws/credentials}:/root/.aws/credentials:ro -v ${WORKSPACE}/test-results:/srv/www/lib/test/html_reports docker exec -it ${IMAGE_NAME} bash -c 'cd test && ruby test1.rb'"
}
}
}
stage('Test2'){
steps {
script {
sh "docker run --rm --entrypoint '' -v \${AWS_CONFIG_FILE:-/home/ubuntu/.aws/config}:/root/.aws/config:ro -v \${AWS_SHARED_CREDENTIALS_FILE:-/home/ubuntu/.aws/credentials}:/root/.aws/credentials:ro -v ${WORKSPACE}/test-results:/srv/www/lib/test/html_reports docker exec -it ${IMAGE_NAME} bash -c 'cd test && ruby test2.rb'"
}
}
}
}
}

I think you can just remove docker exec -it in your commandline
