| 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. |
