@ beginning of pipeline)
i added logger on org.jenkinsci.plugins.docker.workflow.client.dockerclient following result:
apr 07, 2017 3:56:18 pm fine org.jenkinsci.plugins.docker.workflow.client.dockerclient executing docker command docker -v i tried launching docker in stage regular agent, same issue:
pipeline { agent stages { stage("testing 123") { agent { docker { image 'ubuntu:16.04' } } steps { sh 'uname -a' } } } } using docker.pipeline 1.10
this seems related path configuration issue on node, can't find where.
if run org.jenkinsci.plugins.docker.commons.tools.dockertool.getexecutable("docker", jenkins.getactiveinstance(), null, null) in node console, correct (existing, executable) docker path.
any idea ?
thanks lot!
adding ~/.zshenv zshell (or other file) put docker in path. did , problem resolved:
$ cat ~/.zshenv export path=/usr/local/bin:$path it looks docker inspect not run in same env docker pull.
on mac, docker pull failed, configured node/agent add such name: path, value: /usr/local/bin:$path environment variables, docker pull run normally. , docker inspect failed.
then add ~/.zshenv above (and restart node/agent), docker inspect worked finally.
