Title: Message Title

Bartosz Rempuszewski created an issue   Jenkins / JENKINS-60242 tty is not allocated for `sh` step in `docker` agent Issue Type: Bug Assignee: Unassigned Components: jenkinsfile-runner Created: 2019-11-21 13:00 Priority: Minor Reporter: Bartosz Rempuszewski   With test pipeline: pipeline { stages { stage('test tty') { agent { docker { image 'alpine'; alwaysPull true; reuseNode true } } steps { sh "tty" } } } }     I can see in logs:   docker run -t -d [ ... other options ... ] cat so the container is started with tty   but output from `sh` command is: + tty not a tty It looks like shell command is executed with `docker exec somename somecommand` instead of `docker exec -t somename somecommand` Is there a way to start `sh` step with tty enabled?   Note: in case of some commands it is important to run with `tty`, for example https://mustache.github.io/mustache.1.html `mustache --error params template` will fail with error.     Add Comment   This message was sent by Atlassian Jira (v7.13.6#713006-sha1:cc4451f) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
