Jenkins 2.176.2, linux master, agent on macOS 10.13.6
When running a pipeline script like this:
node('docker') { def CURRENT_VERSION def builtImage stage('Clone repository') { checkout scm } stage('Output version') { CURRENT_VERSION = sh (returnStdout: true, script: 'python "${SCRIPTS}/version.py" show all' ).trim() } stage('Build image') { builtImage = docker.build("${DOCKER_IMAGE}:${CURRENT_VERSION}", ".") } stage('Push image') { docker.withRegistry("${DOCKER_REGISTRY}", "${DOCKER_CREDENTIALS}") { builtImage.push() } } }
The build fails on the docker.withRegistry stage with error docker command not found:

The install location on the slave for the docker binary is in /usr/local/bin, which is not by default in PATH.
It is set as an extra variable on the executor configuration by setting an environment variable named PATH+LOCALBIN with value /usr/local/bin.
I managed to override the problem by building a custom version of the plugin, setting the docker command with a hardcoded path in DockerTool.java:58, but it's not a general solution.
