When trying to execute the example from https://github.com/jenkinsci/pipeline-model-definition-plugin/wiki/Controlling-your-build-environment:
pipeline {
agent {
docker 'node'
}
stages {
stage("testing 123") {
steps {
sh 'node --version'
}
}
}
}
I get the following output:
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Agent Setup)

Finished: FAILURE
docker is installed on the server, and is in the PATH: the image is built :-) (docker pull command succeed at the beginning of the pipeline)
I added a logger on org.jenkinsci.plugins.docker.workflow.client.DockerClient with the following result:
Apr 07, 2017 3:56:18 PM FINE org.jenkinsci.plugins.docker.workflow.client.DockerClient
Executing docker command docker -v
I also tried launching a docker in a stage with a regular agent, same issue:
pipeline {
agent any
stages {
stage("testing 123") {
agent {
docker {
image 'ubuntu:16.04'
}
}
steps {
sh 'uname -a'
}
}
}
}
using Docker.Pipeline 1.10
This seems to be related to a PATH configuration issue on the node, but I can't find where.
If I run org.jenkinsci.plugins.docker.commons.tools.DockerTool.getExecutable("docker", Jenkins.getActiveInstance(), null, null) in the node console, I get the correct (existing, executable) docker path.
any idea ?
Thanks a lot!
You can run a shell command that is something like sh "docker 'node'"
What I've done is used a Jenkinsfile and Dockerfile (since I edit my images) and have the Jenkinsfile call a script that has
docker build --tag=image-name .
docker run --rm --name=image-name-container image-name \
./someScript.sh \
-j ${SCRIPT_PARAM1} \
-u ${SCRIPT_PARAM2} > ${DOCKER_OUTPUT_FILE_NAME}
inside of it.
Adding ~/.zshenv for zshell (or other file) to put docker in the path. I did this and problem resolved:
$ cat ~/.zshenv
export PATH=/usr/local/bin:$PATH
It looks like the docker inspect not run in the same env as docker pull.
On my Mac, the docker pull failed, then I configured node/agent to add such Name: PATH, Value: /usr/local/bin:$PATH to the Environment variables, then the docker pull will run normally. And docker inspect failed.
Then I add ~/.zshenv as above (and restart node/agent), the docker inspect worked finally.
